Introduction
This paper concentrates on the innovativeness processes of the information technology (IT) industry, as its development is having a tremendous effect on society as a whole through changes to the way people think, work, live and interact with one another. Technological innovations support assimilating and organizing diverse technological inputs to create original inventions or facilitate successful new product development. This study aims to understand and compare how the mechanism (causal effects) of innovative processes is shaped by knowledge and learning culture in the IT industrythe most innovative industry worldwide. All knowledge is rooted in tacit knowledge (Polanyi, 1966), and several studies have explored tacit knowledge as an innovativeness power. For example, Sheng (2019) and Ganguly et al. (2019) found that tacit knowledge contributes to innovation capabilities. However, what is still needed is understanding of how knowledge and learning culture influence the processes of tacit knowledge awareness and sharing and contribute to internal and external innovativeness. Based on empirical research, knowing exactly how a learning culture composed of a learning climate and mistake acceptance  shapes tacit knowledge awareness and sharing in the context of organizational internal and external innovativeness may be critical for knowledge management. Mistakes are often ignored, yet they may be a precious learning resource. This study aims to deal with this issue.
Undoubtedly, tacit knowledge is a fantastic source of innovation (Ganguly et al., 2019;Jisr and Maamari, 2017;Pé rez-Luñ o et al., 2019). This knowledge is novel and thus beneficial for organizations focused on innovativeness. This form of expertise is specificit is produced and stored in people's minds and is personal rather than communal. In its early stage, it is difficult to be aware of or articulate this knowledge, and its development requires social interactions (Insch et al., 2008). One of the earliest distinctions between explicit and tacit knowledge comes from sociology. Polanyi (1966) noted that "we know more, than we can tell" (p. 4), and introduced a specifictacit kind of knowledge. But tacit knowledge was applied specifically to knowledge management by Nonaka and Takeuchi (1995). Nonaka (1994) conceptualized tacit knowledge in the following two ways: 1. a cognitive aspect including all experiential inputs needed to create an idea; and 2. a technical aspect comprised of new learned skills thanks to acting (learning by doing).
More recently, the two-part categorization has had suggested extensions, including the third aspect of effectuation or "what I know" (Jisr and Maamari, 2017) and an aspect of socialization, characterized by task-related interaction and social interaction (Insch et al., 2008). The latter view makes explicit the idea that, even though tacit knowledge tends to be gained through personal experience and might be learned through repeated on-the-job activities, it can also be obtained by means of guidance from another willing to share their knowledge (Olaisen and Revang, 2018).
Asher and Popper's (2019) recent conceptualization of an "onion" model posits different layers of tacit knowledge and a description of knowledge as a matter of degree along a single axis, where knowledge is more explicit at one end and more tacit at the other end, with elements of both forming the middle. The forms of knowledge range from more explainable and closer to explicit knowledge to virtually impossible to explain and only demonstrable, at the furthest reaches of tacit knowledge (perhaps verging on insight/ intelligence). Ryan and O'Connor (2013) examined software project teams and claimed that tacit knowledge is acquired and shared directly through good quality social interactions between team members. Koriat and Gelbard (2014) studied IT teams and claimed that exchanging tacit knowledge is a real challenge today. Tacit knowledge is personal, therefore sharing it cannot be formalized or forced (Kucharska and Kowalczyk, 2016). Thus, understanding the acts of acquiring and sharing tacit knowledge are crucial for innovativeness in IT. This study aims to explore this issue.
Without organizational learning, there can be no sustainable organizational innovativeness in response to the changing world (Choi and Chandler, 2020;Bjö rkdahl and Bö rjesson, 2012;Bligh et al., 2018). There is also no learning without mistakes (Van Dyck et al., 2005). All people make mistakes, but especially those who actively seek new horizons, break conventions and want to learn and grow, as observed in the IT industry. Therefore, this study examines the cultural factors of learning climate and mistake acceptance  as a potential stimulus of tacit knowledge capturing. The recent studies by Farnese et al. (2019Farnese et al. ( , 2020 demonstrated the importance of cultural orientation to learn from errors. If organizational culture is important for mistakes, the national cultural context must also be influential. Therefore, this study presents a comparison of Poland and the USA in the context of organizations gaining tacit knowledge from mistakes to increase innovativeness. This comparison is significant, given that the USA is one of the most technologically innovative countries. In contrast, Poland is a post-soviet nation that, however fast-growing is only 30 years free from the soviet system. So, this long-lasting national experience of the soviet system might still be reflected in business culture. Such harmful events may have lasting effects for generations, which could influence both focuses of this studya learning culture that accepts mistakes and knowledge sharingas both these factors require organizational safety (Andersson et al., 2020). Thus, this study aims to understand and compare how the mechanism of innovative processes in the IT industry -the most innovative industry worldwideis shaped in Poland and in the USA in terms of tacit knowledge awareness and sharing driven by a culture of knowledge and a learning culture composed of a learning climate and mistakes acceptance.

Conceptual framework
Errors, mistakes and failuresall refer in some manner to actions that have unintended effectsand the approaches to perceiving, defining and managing them differ, depending on the industry lens. Errors relate to a deviation from norms, and this term is often used in error management studies in production (Seifried and Hö pfer, 2013;Love et al., 2018;Seckler et al., 2017). A mistake is usually associated with a wrong decision (Mangels et al., 2006) and could be caused by, for instance, data errors. Meanwhile, failure is conceptualized as the lack of the desired results, and it includes avoidable mistakes and the unavoidable negative outcomes of risk taken, such as in experiments or new venture creation (Cannon and Edmondson, 2001;Politis and Gabrielsson, 2009). Therefore, failure could be equally attributable to negligence and diligence when acting under uncertain conditions, characteristic of early-stage entrepreneurs (e.g. those launching startups) or mature entrepreneurs seeking new business opportunities. Senders and Moray (1991) described an error as the act that is "not intended by the actor; not desired by a set of rules or an external observer, or that led the task or system outside its acceptable limits" (p. 25). Frese and Keith (2015) defined it as "unintended deviations from plans goals, or adequate feedback processing, as well as incorrect actions resulting from lack of knowledge" (p. 662). Error management is defined as an organizational strategy to minimize the negative consequences of errors through early detection and correction and to prevent errors through learning (Van Dyck et al., 2013). In this regard, the aviation industry (Hagen, 2013) and the construction industry (Love et al., 2013(Love et al., , 2015(Love et al., , 2106(Love et al., , 2018 have adopted this strategy. In addition, the health-care industry offers many positive examples and ideas related to error management and learning from errors (Fischer et al., 2006;Kalender et al., 2020;Metcalfe, 2017;Van Dyck et al., 2013;Waeschle et al., 2015). Kalender et al. (2020) and Anderson and Abrahamson (2017), similarly to Zhao and Olivera (2006), noted that a critical problem regarding organizational learning from mistakes is the lack of reporting, and therefore, they highlighted the need for change in organizational attitudes toward errors. Further, Ferguson (2017) and Robertson and Long (2018) asserted that the lack of reporting in the health-care field may be caused by the organizational "culture of blame and shame" (p. 404). If mistakes are hidden, they cannot serve as lessons for anyone except those who make them. Thus, Mohsin et al. (2019) suggested that error reporting should be a standard taught at medical school.
Many positive examples of learning from mistakes have emerged from entrepreneurship studies, that is, from entrepreneurial learnings from business failures (Cardon et al., 2011;Cope, 2011;Eggers and Song, 2015;McGrath, 1999;Politis and Gabrielsson, 2009;Shepherd, 2003;Yamakawa and Cardon, 2015). Recent studies on the hospitality industry (Guchait et al., 2016(Guchait et al., , 2018Pasamehmetoglu et al., 2017;Jung and Yoon, 2017;Wang et al., 2020) simplified the organizational attitude toward errors to the primary question: Should mistakes at work be tolerated? As they observed that error tolerance yields positive outcomes for employees, such as psychological safety, self-efficacy, supportive employee behaviors, employee learning and increased error reporting ratesthey asserted that it should be tolerated. Moreover, the organizational gains through reporting are work engagement and service recovery performance. Frese and Keith (2015) and Weinzimmer and Esken (2017) studied learning from mistakes and revealed that the essence of deep organizational learning is to identify and modify errors. It is visible in the error management approach in IT.
Error management studies on IT are classified into four categoriesmethods, people, tools and requirements (Anu et al., 2018;De Felice and Petrillo, 2017) and focus on error detection and correction, often by applying statistical methods (Challa et al., 2020;Di Sanzo et al., 2021;Singh and Walia, 2020). Software development is a knowledge-intensive process, and in this field, employees' cognitive failures are the primary causes of software errors (Balaji and Murugaiyan, 2012). Therefore, learning from mistakes in this field is focused on reflections throughout the software development lifecycle (i.e. analyzing errors in requirements, coding and testing) by adopting, for instance, the V model for testing (Akinsola et al., 2020) or an approach to improve the software development process, such as the capability maturity model (Huang and Liu, 2017) or the agile retrospective process as part of the Scrum method (Annosi et al., 2020;Gaikwad et al., 2019). Agile learning is supported by a learning culture in IT (Tripathi et al., 2020), and this support is crucial for continuous innovation (Denning, 2013).
Innovation in the IT industry in the context of organizational culture has attracted much attention recently (Abubakre et al., 2020;Bourdeau et al., 2020;Fan et al., 2019;Nguyen et al., 2019). However, none of the studies has considered the culture of knowledge or learning in the context of tacit knowledge. As tacit knowledge is a source of innovation (Kodama, 2019) and a culture that enables creating a channel of knowledge flows supports tacit knowledge sharing (Mabey et al., 2012;Mabey and Zhao, 2017), such studies are important. Moreover, Cabrilo et al. (2018Cabrilo et al. ( , 2020 demonstrated the direct and positive influence of intellectual capital on organizational innovativeness in IT. Saint-Onge (1996) noted that tacit knowledge influences organizational intellectual capital. Therefore, tacit knowledge is perceived as vital for innovativeness (Ganguly et al., 2019;Pé rez-Luñ o et al., 2016. Therefore, to fill this literature gap, this study focuses on how tacit knowledge can be captured in the IT industry driven by a culture of knowledge and a learning culture composed of a learning climate and mistake acceptance. Mistakes are often perceived as an unwelcome side effect of human learning; however, they can be a precious experience resource enabling learning, if they are accepted. We cannot learn from mistakes if we do not accept them. Nonaka and Takeuchi (2019), developing the SECI approach that they proposed in 1994, stressed that continuous innovation results when companies constantly and repeatedly create new knowledge. Mistakes seem to be a good stimulus for constant learning as a result of the comparably easy access to mistakes, given that we all make them. Knowledge capture is a prerequisite for enhancing innovation and performance (Rutten et al., 2016). Several studies have highlighted that knowledge sharing fosters idea generation among employees, which enables innovation (Henri, 2016) and effective organizational change (Park and Kim, 2015). However, there is a lack of studies exploring the capture of tacit knowledge from mistakes to support organizational innovativeness. This study aims to fill this gap.
Knowledge culture and constant learning culture Islam et al. (2015) described knowledge culture as conditions that support the broad flow of knowledge in an organization. Knowledge culture is a base for organizational development in a knowledge-driven economy (Powell and Snellman, 2004); however, passive knowledge is insufficient to bring business value. Knowledge in use (in action) is needed. As Rothberg and Erickson (2017) stated, knowledge in action requires strategic and tactical intelligence, which derives from the organization's intellectual capital and knowledge processes. Nonaka and Takeuchi (2019) confirmed the SECI approach when they developed the SECI model that they had presented in their 1994 study. They noted that continuous innovation results from companies constantly and repeatedly creating new knowledge, disseminating the knowledge and converting the knowledge into explicit knowledge and action. To achieve this, the set of knowledge routines visible in the organizational pattern of behaviors must be developed. Such a pattern of knowledge-related behaviors determines a knowledge culture of the company. Culture is the "key ingredient in shifting from knowledge to intelligence" (Rothberg and Erickson, 2017, p. 283). Mueller (2014Mueller ( , 2018 noted that knowledge culture and learning culture are both vital, but learning culture is essential for constant development. Garvin (1993, p. 80) defined learning culture as "an organization skilled at creating, acquiring, and transferring knowledge and modifying its behavior to reflect new knowledge and insights." Thus, a desire to possess knowledge is a motivation for learning. Learning fosters the knowledge development, but a knowledge culture must enhance the positive attitude and motivation among employees to learning routines. Kucharska and Bedford (2020) defined constant learning culture as comprising a learning climate and mistakes acceptance. Hence, it can be concluded that a knowledge culture supports both of learning culture's components. Zappa and Robins (2016) noted that the essence of organizational learning is to identify and modify errors. Therefore, based on all the above information, the following hypotheses were proposed: H1a. Knowledge culture positively influences the learning climate.
H1b. Knowledge culture positively influences the acceptance of mistakes.
Moreover, Ö rtenblad (2002) noted that learning climate encourages learning through trial and error and enhancing reflection. Therefore, H2 was developed as follows: H2. A constant learning climate positively influences mistakes acceptance.

Constant learning culture and tacit knowledge
A constant learning culture is composed of the overall learning climate and mistakes acceptance as an internal part of the learning process. We cannot learn from mistakes without accepting them. The studies by Farnese et al. (2019Farnese et al. ( , 2020 stressed the importance of cultural orientation to learn from errors. Moreover, Vanderheiden and Mayer (2020) highlighted the cultural factor of mistake perception. Mistakes are probably one of the most common human experiences and, equally, one of the least appreciated, despite being vital for learning (Guchait et al., 2015;Harteis et al., 2008;Simonsson and Heide, 2018). There is no learning without mistakes (Van Dyck et al., 2005). Thus, considering all the above, it is assumed that learning from mistakes is an opportunity to gain tacit knowledge. From Saint-Onge (1996) perspective, tacit knowledge is organizational knowledge on a greater level, given its contribution to novelty creation. It is composed of intuition, personal beliefs, assumptions, attitudes, values and overall experiences at the individual level. As Polanyi (1966) stated, we know more than we can tell, and we know more than we can logically explain (Dö rfler and Ackermann, 2015; Koestler, 1971). It is easier to sense or observe tacit knowledge than to describe it during its very early stage. Asher and Popper's (2019) "onion" model introduced various layers of tacit knowledge related to tacitness degrees. From their point of view, three layers are focal: a hidden practical layer, a tacit reflective layer and a demonstrated layer. This suggests that the level of tacitness determines awareness and sharing. Tacit knowledge sharing requires trust collaboration and an overall learning climate and psychological safety (Kucharska and Kowalczyk, 2016;Andersson et al., 2020). Therefore, the mistakes acceptance component of the constant learning culture, alongside learning climate, is vital for tacit knowledge awareness. Based on the above elaboration, hypotheses were developed as follows: H3a. A learning climate facilitates tacit knowledge awareness.
Olaisen and Revang (2018) advocated for a three-level model that reveals the essence of tacit knowledge awareness and sharing. The levels are representable knowing, nonrepresented knowing and non-representable knowing. In the current research, tacit awareness is presented as the stage at which tacit knowledge evolves to a stage enabling the articulation of new ideas through metaphors, demonstrations, contextual storytelling or sharing impressions. Therefore, in its early stage, tacit knowledge can be called "intuitive knowledge." Following El-Den and Sriratanaviriyakul (2019), tacit knowledge awareness is the stage at which an individual realizes something new (e.g. an opinion or idea). At this stage, it can be shared. Therefore, the following hypothesis was developed: H4. Tacit knowledge awareness positively influences tacit knowledge sharing.

Tacit knowledge and innovations
Tacit knowledge fosters innovations (Berraies et al., 2020;Goffin et al., 2010;Goffin and Koners, 2011;Jimé nez-Jimé nez and Sanz-Valle, 2011;Jisr and Maamari, 2017;Kodama, 2019;Pé rez-Luñ o et al., 2016;Sakellariou et al., 2017;Sheng, 2019). As a result of tacit knowledge acquisition and recognition at the individual level, knowledge can be applied and shared at work and thanks to this shifted to communal level. Knowledge acquisition is a precondition for innovation (Rutten et al., 2016); if knowledge is not acquired, it cannot be shared. Moreover, Henri (2016) highlighted that knowledge sharing fosters idea generation among employees, which undoubtedly fosters innovation. Innovation can be perceived in several ways, but product versus process innovation is common (Eidizadeh et al., 2017; Jimé nez-Jimé nez and Sanz-Valle, 2011). The product or service innovation concept is wellestablished by many researchers, including Sheng (2019) and Ganguly et al. (2019), and it was operationalized by Kucharska and Erickson (2021). Product innovation relates to changes in an existing product or service in the aim of its development or the introduction of a new product or service. For clarity, this study refers to market-oriented external innovation, understood as product or service innovation and internal innovation, which refers to innovative methods of working. Process innovation, as the name suggests, develops operational management processes. Thus, tacit knowledge is a source of innovation (Brachos et al., 2006;Ganguly et al., 2019;Goffin et al., 2010;Goffin and Koners, 2011;Jisr and Maamari, 2017;Kodama, 2019;Pé rez-Luñ o et al., 2019;Sakellariou et al., 2017;Sheng, 2019). Both service and product innovation, in contrast to internal-oriented innovations of aspects, such as processes, are market-oriented innovations. Therefore, for the purposes of this study, these innovations are referred to as market innovations. Besides, the innovative working methods may also inspire the external innovations of the product or service. These external innovations obtained thanks to internal often occur because of technological innovations (Donbesuur et al., 2020). So, it suggests that new solutions might inspire new ideas. As Crane and Bontis (2014, p. 1136) stated, "tacit knowledge is acquired unconsciously and automatically, but capable of influencing action." Based on this, the following hypotheses were formulated: H5. Tacit knowledge awareness positively influences process innovation.
H6. Tacit knowledge awareness positively influences market innovation.
Moreover, Hagedoorn and Wang (2012) suggested that complementarity exists between internal and external innovativeness, while Wong and Chin (2007) and Jimé nez-Jimé nez et al. (2008) noted that internal process innovations might increase overall innovativeness. Therefore, it is assumed that internal innovations may significantly support external, marketoriented product or service innovations. Thus, the following hypothesis was proposed: H9. Process innovations positively influence market innovations.

Control variables
A control variable (CV) represents an additional factor (third variable) that may influence the relationship between an independent and dependent variable. A CV may act as a confound, a moderator or a suppressor (MacKinnon et al., 2000;Spector and Brannick, 2011). The CV's imputation methodology enables extraneous variables to be included in a modelthey are not the focal point of the study, yet remain theoretically important (Becker et al., 2016;Kish, 1959;Nielsen and Raswant, 2018). For this study, such theoretically important variables were risk and critical thinking. Tacit knowledge is highly personal; thus, for this knowledge to arise, reflexivity is needed. All experience gained must be facilitated by critical thinking to create new knowledge (Oswald and Mascarenhas, 2019). Moreover, knowledge sharing, especially tacit knowledge, may also depend on risk-taking readiness. Risk taking implies uncertainty acceptance (Zinn, 2020). Tacit knowledge is novel, sometimes not fully developed, and just newly learned; thus, implementing such new learning in practice can require a certain degree of risk. Sharing, externalizing and implementing novel knowledge must be undertaken by somebody, mentally ready to be wrongthis person must feel comfortable and safe in facing uncertainty and risk in front of others (Andersson et al., 2020). Therefore, the general risk-taking attitude toward internal innovation introduction was included in this study as a CV. Based on all the above, the hypotheses were developed as follows: Cv1. Critical thinking positively influences tacit knowledge awareness.
Based on all the above assumptions, the theoretical model was developed and is presented in Figure 1.

Questionnaire
According to deVellis (2017, p. 2), "measurement is a fundamental activity of science." Social science measures focus on social constructs that are not easy to measure directly via, for example, observation. Hence, scales, which are collections of statements that reflect the meaning of a construct, are used to reveal unobserved social variables. Moreover, the methodological literature warns that measurement bias may occur by statement overlap (deVellis, 2017). Therefore, the current authors proposed their own scales, based on existing studies' findings and definitions, to ensure that the statements did not overlap and that the proposed model measured all constructs correctly to examine the above-described relations accurately and fulfill the study objectives. In summary, the first statements were developed according to given definitions from prior qualitative studies' findings, and then these scales were validated according to procedures described by deVellis (2017). Table 1 Figure 1 Theoretical model j JOURNAL OF KNOWLEDGE MANAGEMENT j presents a summary of this stage of the studynamely, the measured constructs and their definitions, and statements of the proposed measurement scales.

Sampling
The study's sensitivity and complexity required high-quality sampling procedures; however, given the population size (in Poland and the USA) and dispersion, simple random sampling would have been challenging. Therefore, panel-based quota samplingwith Poland's labor market structure as the reference (Statistics Poland, 2017)provided the necessary randomness with reasonable efficiency. Sampling administration was provided online and executed by professional partners, Qualtrics (USA) and ASM (Poland). Survey execution took two months (January to February 2020). The questionnaire started with a short introduction that provided an overview of the study, including a definition of tacit knowledge. Next, a qualification question was asked to establish the respondents' minimum work experience and Knowledge culture is consisted of all surrounding conditions that support the effective and efficient flow of knowledge throughout the whole organization (Islam et al., 2013(Islam et al., , 2015 All employees perceive knowledge as a value We have a common language to support knowledge exchange We are encouraged to share knowledge, ideas and thoughts We care about quality of knowledge we share (Kucharska and Bedford, 2020) Learning culture "(. . .) learning as one of the organization's core values, a focus on people, concern for all stakeholders, stimulation of experimentation, encouraging an attitude of responsible risk, readiness to recognize errors and learn from them, and promotion of open and intense communication, as well as the promotion of cooperation, interdependence, and share of knowledge" (Rebelo and Gomes, 2011a, p. 174) Hence, organizational constant learning culture is composed of "learning climate" and "mistakes acceptance." "Learning climate" dimension: All staff demonstrate a high learning disposition We are encouraged to personal development We are encouraged to implement new ideas every day We are encouraged to new solutions seeking "Mistakes acceptance" dimension: People know that mistakes are learning consequence and tolerate it up to a certain limit Most people freely declare mistakes We discuss problems openly without blaming Mistakes are tolerated and treated as learning opportunities (Kucharska and Bedford, 2020) Critical thinking "Critical thinking (CT) is constructive thinking about the world of ours that questions and evaluates its operations, history, and management" (Oswald and Mascarenhas, 2019, p. 151) Making sense of things is important to me I learn from constructive questioning I like to evaluate my work and find out better solutions on my own (Kucharska and Erickson, 2021) Tacit knowledge awareness Tacit knowledge is a common outcome from many episodes of non-formal learning. It is often a reactive, situational nearspontaneous and unplanned process. The learner is usually aware of it, but the articulation of its effects in explicit form is delicate without setting aside time for more refection and thus becoming deliberative (Eraut, 2000) I can create and explain new ideas or insights Even if my idea is hard to explain, I am able to express it or demonstrate it Sometimes I am absolutely sure about a new idea but find it difficult to express As I have accumulated experience, I find it is easier to express (Kucharska and Erickson, 2021) Tacit knowledge sharing Tacit knowledge sharing is a voluntary, social process. Sharing informal knowledge is an informal voluntary act of the knowledge owner (Kucharska and Kowalczyk, 2016) The tacit knowledge is obtained and shared through experience (Gö ksel and Aydintan, 2017) I share knowledge learned from my own experience I have the opportunity to learn from others' experiences Colleagues share new ideas with me Colleagues include me in discussions about best practices (Kucharska and Erickson, 2021) Process innovation Process innovation is an ability to constant improvement methods of working (Manu, 1992 We constantly improve the way we work We are good at managing changes We are highly disposed to introduce new methods and procedures We are highly disposed to accept new rules (Kucharska and Erickson, 2021) Product or service innovation Product or service innovation is an ability to introduce a competitive new product or service on the market (Manu, 1992;Jimé nez-Jimé nez et al., 2008;Jimé nez-Jimé nez and Sanz-Valle, 2011;Eidizadeh et al., 2017) We provide competitively superior innovations to our clients Our innovations are perceived positively by our clients We are better than competitors at introducing innovations I am proud of our innovations (Kucharska and Erickson, 2021) status as a "knowledge worker" in the IT industry. Respondents were also prompted with a short explanation of the meaning of "tacit knowledge" to ensure they understood what they were asked. The survey's core, excluding classification items, used a seven-point Likert scale to assess the intensity of statements. Data management was straightforward. Only fully completed questionnaires with SD > 0.4 were included. Table 2 presents the sample structure.
The main difference between samples was the structure of company size. US companies were mostly represented by large companies, whereas Polish companies were mostly small-and medium-sized enterprises.

Data quality
The sample quality assessment started with invariance, then the Kaiser-Meyer-Olkin (KMO) measure of sampling adequacy and Harman one-factor tests. The samples came from two countries; thus, the invariance tests of adequacy were run first to verify if the measurement instrument operated properly across different populations. All scales were proposed by the authors, so required validation. Namely, this test measures if the questionnaire is nationally invariantworks properly in different populations. Thus, it verified if the questionnaire composed of the scales presented in Table 2 measured the constructs properly in both samples. To achieve this, multigroup confirmatory factor analysis (CFA) was applied (Byrne, 2016). For both samples included in the research size n > 300, so the liberal alternative of models' global fit indices were appliedcomparative fit index (CFI) and root mean square error of approximation (RMSEA) (Chen, 2007). The measured change (D) in model fits was about 0.01 or less for CFI, and 0.015 or less for RMSEA; thus, the measurement model was nationally invariant (Byrne, 2016;Chen, 2007;Raudenska, 2020). Table 3 presents the  details of the invariance measurement, which indicate that the applied scales in the questionnaire created a nationally invariant tool. Table 3 presents the invariance  measurement, while Table 4 presents the sample quality assessment.
Summarizing this stage, for all obtained KMO tests of the sample's adequacy, results were 0.872 for Poland and 0.927 for the USA, which confirmed that the samples were adequate (Hair et al., 2010;Kaiser, 1974). In addition, we ran one Harman single-factor test (Podsakoff and Organ, 1986), and both samples achieved an acceptable result, with 30% for Poland and 39% for the USA, which confirmed that the sample quality was good and enabled further analysis.

Measures
After positive verification of the sample and questionnaire quality, CFA was conducted to assess the convergent and discriminant validity of the empirical models run, separately for Poland and the USA, based on the theoretical model presented in Figure 1. The critical thinking (CT) and risk (RISK) CVs were imputed. CT was operationalized as a composite variable from the seven-point Likert scale. The mean value of CT was 6.45 (Poland/USA). Thus, the imputation of CT as the CV in the ordinal scale was the best option to measure the influence of CT properly (differences between respondents were sensitive). RISK was measured and operationalized more simply (1 = risk-taking person, 0 = opposite). For Poland, the majority worked in small companies, and 78% of respondents described themselves as risk-taking people. The majority of the US sample comprised employees working in large companies, where 69% of respondents described themselves as risktaking people. All latent variables were measured using seven-point Likert scales. The other measured constructs achieved indicator loadings (standardized) above the reference level of >0.6 (Bartlett, 1950;Fornell and Larcker, 1981;Hair et al., 2010).
The internal consistency of the constructs was assessed using Cronbach's alpha > 0.7 (Francis, 2001) and average variance extracted (AVE) > 0.5 (Byrne, 2016;Hair et al., 2010). Further, composite reliability > 0.7 (Byrne, 2016;Hair et al., 2010) was used to justify the reliability of the scales. Next, after the positively assessed statistical power of the chosen items, discriminant validity was checked (deVellis, 2017;Fornell and Larcker, 1981;Hu and Bentler, 1999). Namely, similar theoretically related constructs were verified to ensure they did not supercharge each other (Fornell-Larcker criterion). The obtained square root of the AVE was larger than the correlation observed between the constructs for all except the process innovation (PI) and market innovation (PSI) variables in the US model, which meant that the discriminant validity of the proposed scales worked properly, except for this one case, which required deeper investigation. Therefore, Model C for the US sample was later run, analyzed and elaborated to further explain the relation between internal and external innovations in the IT industry in the USA. Table 5 presents the obtained basic statistics and correlations between the measured constructs.
The mean values for critical thinking, tacit knowledge awareness and knowledge culture were very close for Poland and the USA, while the mean values for process innovation and market innovations were slightly higher for the US sample. The mean values for learning climate and j JOURNAL OF KNOWLEDGE MANAGEMENT j mistakes acceptancethe learning culture variableswere lower for the Polish sample. Therefore, learning culture, tacit knowledge sharing and internal and external innovations were areas where differences between Poland and the USA were expected (Figure 1).

Results
The results obtained for Poland and the USA are presented based on two models: Model Arun with CVs, and Model Brun without CVs (Aguinis and Vandenberg, 2014;Carlson and Wu, 2012). The results of both models are presented following the procedure suggested by Becker et al. (2016) in Table 6. Based on these results, the conclusion was reached that Model B with imputed CVs fit the data better for both samples -Polish and American. Thus, further analysis based on Model B with CVs was undertaken and discussed. Additionally, for the American sample, Model C without the PSI (external innovations) variable was analyzed, as the Fornell-Larcker criterion was not fulfilled for the American sample in Model B, yet the common method bias and Harman one-factor tests achieve acceptable levels ( Table 4)none of the results exceeded 50% (Fuller et al., 2016;Podsakoff et al., 2012). Therefore, Model C was created to verify if PSI variable inclusion in the model was justified. Namely, if PI (internal innovations) supercharged PSI (external, market innovations), then it may be better to exclude this variable. The results obtained for Model C demonstrated that inclusion of both variables -PI (process innovation) and PSI (market innovations)was necessary to fully understand the whole mechanism of learning via mistakes to develop innovativeness in IT organizations. PSI inclusion was justified because Model B (with both PI and PSI variables) obtained R 2 = 89%, whereas, without PSI, it obtained only 24%. Altogether, this indicated that the PSI variable should be included and analyzed for better understanding the whole explored mechanism of relations. Based on the presented results, it may be theorized that the IT industry in the USA is simply innovation oriented, and all internal innovations are focused on market innovations delivery (b = 0.87 ÃÃÃ ). Moreover, Model B fitted better to the data than Model C. Therefore, the Notes: Poland, n = 350; USA, n = 379; KC = knowledge culture; TKA = tacit knowledge awareness; CT = critical thinking; LA = learning culture (atmosphere/climate); LM = learning culture (mistakes acceptance); TKS = tacit knowledge sharing; PI = process innovation; PSI = market innovation (product or service); RISK = risk taking conclusion was reached that the American IT industry is greatly consistently innovation oriented. This conclusion is supported by the fact that PI supercharges PSI (Table 5b). However, if the PSI variable is excluded (Table 6, Model C), the model quality decreases, as described above. Thus, it means that internal innovations in the US IT companies strongly support external innovations. Moreover, the influence of tacit knowledge sharing on market innovations is fully supported by internal innovations.
Thus, the internal processes of IT companies (represented in 66% by large companies) are market innovation oriented, whereas in Poland (represented in 77% by small companies), they are not. This is a particularly important discovery worth discussing in greater depth, especially in the context of the full results obtained based on hypotheses verification (Table 6). Figure 2 presents graphically all the obtained results based on Model B with CVs.
This study aimed to understand and compare how the mechanism of innovative processes in the IT industry is shaped in Poland and the USA in terms of tacit knowledge awareness and sharing driven by mistakes acceptance. There was no other way to undertake this investigation in detail with a simple model. Therefore, the presented model comprises seven latent variables linked by 11 hypotheses to ensure that the whole mechanism was simulated  and ensure two critical CVs were imputed and the indirect (mediated) effects were analyzed. So, elaborating the model quality issues, it is methodologically correct if such complex model obtain slightly lower than referenced by Bentler (1990) 0.9 CFI and referenced TLI also 0.9 (Tucker and Lewis, 1973) levels if only RMSEA and CMIN/df are correct (Cheung and Rensvold, 2009). Exactly this situation was observed in the case of the present study. This study was complex because the study aim required itnamely, detailed modeling was required to understand the mechanism of learning from mistakes to increase innovativeness via tacit knowledge awareness and sharing. Simplification by reducing degrees of freedom would somewhat improve the quality of the model, but the delivery of the knowledge in which we were interested would be at risk. Table 6 and Figure 2 visualize the obtained results.
The R 2 of the model developed based on the Polish IT sample obtained 52%. This result indicates that other important factors influence the market innovativeness of Polish companies that were not included in this research. The R 2 obtained was 89% for the US IT sector, which was perceived as impressive and the obtained results could thus be discussed as endorsed.

Discussion
The presented study results exposed several issues. Starting from knowledge culture, the influence of it on learning culture is equally observed for Poland and the USA, but only in terms of learning climate (H1a). When considering the mistakes acceptance component, for Poland, this influence was not significant, whereas, for the USA, the result was the opposite (H1b). This means that, in Poland, there exists some kind of "learning illusion"namely, employees are expected to learn without making mistakes. This finding aligns with Kucharska and Bedford's (2020) findings. They observed that Polish employee intelligence increases by learning from mistakes, whereas organization's intelligence is not. For the US sample, mistakes acceptance significantly influenced tacit knowledge awareness (H3b), whereas, for the Polish sample, it did not. Inversely, the learning climate positively influenced tacit knowledge awareness for Poland, yet was not significant for the USA. Thus, this situation is a result of knowledge culture, which, in Poland, supports learning climate (H1a), yet ignores mistake acceptance (H1b). For the US sample, both learning culture componentsmistakes acceptance and learning climatewere fostered by knowledge culture. However, the direct and indirect (mediated) effects of the learning climate on tacit knowledge awareness were both not significant. This means that, for IT in the USA, the mistakes acceptance factor of the learning culture is a focal stimulus for tacit knowledge awareness. This finding aligns with Ö rtenblad (2002) that a learning climate encourages learning through trials, experiments and errors, and enhances reflections. Developing these thoughts, Srirama et al. (2020) examined the IT sector in India, and noted that it is important to allow employees to experiment, explore and debate. To achieve true learning, organizations must create a working environment where people can discuss without hesitation, and employees must be able to accept critical feedback and questioning. This highlights the second important issue noted in this studythat true learning derives from mistakes acceptance. According to Senge's (2006) statement, to truly learn, we must be ready to be wrong. This study demonstrates this empirically. Moreover, learning climate mediates between knowledge culture and mistakes acceptance, as observed for both Poland and the USA. This means that learning climate is an important facilitator for learning from mistakes.
The next tremendous difference between models worth to be discussed is tacit knowledge awareness influence on internal and external innovations. Tacit knowledge awareness is the moment when we start to realize something new, so we have learned something. As Crane and Bontis (2014, p. 1136) stated, tacit knowledge is on its early stage "acquired unconsciously and automatically, but capable of influencing action." This statement was supported by the current study's findings. However, although the direct influence of tacit knowledge awareness on external innovations (H6) was not significant, and on internal was significant only for Poland; this influence was mediated by tacit knowledge sharing. Namely, tacit knowledge awareness influence on market innovations was fully mediated by internal innovations. In contrast, for Poland, mediation is noted for internal innovations, and the direct effect of tacit knowledge awareness on PI was significant (H5), and the mediation of internal innovations was partial. Further, for the USA, tacit knowledge sharing (H4) was crucial for innovativeness (internal and external). Process innovation directly influenced market innovation and was high and significant for both samples; however, the US internal innovativeness in the IT industry strongly supports market innovativeness. As noted in the results section describing the high correlation between PSI and PI for the US sample, and in the poor results of Model Cwhich was run only to test what would occur with the whole model when PSI was excluded -Model C was much weaker than Model B, where, despite the high correlation between PI and PSI, bias was not observed. Altogether, these results indicate that the IT industry in the USA is completely innovation oriented, and all internal innovations are focused on improving methods of working to create better external innovations. Notably, the direct influence of tacit knowledge sharing on market innovation was not significant (H8), but the indirect effect was significant. Further, the impact of TKS on PSI was fully mediated by PI (internal innovations). All these results suggest that there is a remarkable internal innovation mindset in the US IT industry that affects externally oriented innovativeness (market innovations). This is important empirical evidence delivered by this researchnamely, that true learning leads to innovativeness consistency of organizations, as evident in internal and external innovativeness.
More light on this situation put an analysis of CVs: critical thinking and risk. Both CVs were significant for the US samplenamely, critical thinking mattered for tacit knowledge awareness and risk-taking attitude mattered for process innovations. For the Polish sample, risk was not a significant influencer, whereas critical thinking was (Table 5). This finding was interesting. As Zinn (2020) stated, risk taking implies uncertainty acceptance. Tacit knowledge is novel, sometimes not fully developed, and just newly learned, so implementing such new learning in practice includes a certain degree of uncertainty, such as the risk of mistake. Therefore, for the Polish sample, where mistakes are not accepted, employees do not take the risk, and their innovativeness is not as strong as in the USA. Another issue worth discussion is the fact that the Polish sample comprised a majority of small company entrepreneurs who declared themselves risk-taking people, and the average level of the critical thinking factor in the Polish sample was also high. This means that the lack of mistakes acceptance affects the learning process, thereby influencing tacit knowledge awareness much more intensively in Poland than in the USA. To enable a better understanding of these theorized interrelations, Figure 3 presents a visualization of tacit knowledge awareness, mistakes acceptance, risk taking and critical thinking. This visualization is presented for the US sample because all these factors were significant only for the USA. Figure 3 presents that employees with the strongest critical thinking obtained the highest level of tacit knowledge awareness in the group of risk-taking employees, which correlated with the highest level of mistakes acceptance. Based on this visualization, the conclusion reached was that a high level of mistakes acceptance stimulated by a risk-taking attitude generates a high level of tacit knowledge awareness because of critical thinking. The same strong level of critical thinking without a risk-taking attitude generates a stable level of tacit knowledge awareness, even when mistakes acceptance is high. This suggests that risktaking attitude is only partially shaped by working conditions. The best example of this is that "critical thinkers" on the higher level, who are not risk-taking people, obtain a lower level of tacit knowledge awareness than those whose critical thinking is not as high but are ready to take a risk. Namely, the inner criticism of persons who cannot take a risk kills new ideas. So, critical thinking without readiness to take a risk is not good for tacit knowledge capturing. All the above findings lead to interesting practical and scientific implications.

Implications and limitations
Tacit knowledge is personal, and this study indicates that organizational culture might significantly stimulate tacit knowledge, yet the personality of the employee is shaped by their home culturefor example, family, friends, former experiences and national culture may also influence readiness to gain tacit knowledge and implement it in action. Both samples were represented by knowledge workers, so personal, intellectual disposition was not the issue of this study. The essence was the individual and communal attitude shaped Figure 3 Mistakes acceptance and tacit knowledge awareness in terms of critical thinking and risk-taking conditionsthe US case by cultureorganizational and national . This national culture influence may also explain why Polish employees' attitudes toward mistakes acceptance and risk taking are so negative and so opposite to those presented by the US IT knowledge workers. Poland is a post-soviet country who, after harmful the Second World War experiences, lived more than 50 years in fear. Such harmful events can affect many generations. It is an interesting topic for sociologists to investigate how deeply and how long such hidden fear can be transferred at unconscious levels through generations. Therefore, it is worth examining other post-soviet countries. Does their national experience affect the way tacit knowledge is created, shared and generally managed? Does it differentiate across industries? Which factors influence tacit knowledge sharing in large and small companies? The obtained differences observed in this study between the USA and Poland may also be caused by company size factor. These questions require further research.
Practical implications based on the presented findings are clear. The illusion of learning without making mistakes causes a kind of organizational waste, reflected in the lost opportunity to learn. True learning comes from mistake acceptance, as empirically demonstrated by this study. Thus, organizations should develop a culture and rules to support learning from mistakes. If a true learning culture leads to remarkable "consistent innovativeness," both internal and external. Therefore, the organizational effort needed to support learning from mistakes is worth investing in. If a company can support learning from mistakes by developing an appropriate culture and selecting suitable leaders, then the chance for tacit knowledge capturing and sharing grows. Another important factor is hiring suitable peoplenot only leaders but generally, all knowledge workers, who think critically and take risks of the uncertainty of new ideas formulation. If not, the organizational effort to organize the learning process may be lost.
The main limitation of this study is that it provided a comparison between two countries (including one of the most innovative globally) and one industry (also the most innovative globally). Thus, further studies exploring other countries and industries would be beneficial to learn more about the "mistake acceptance" phenomenon around the world. It would be useful to include other Asian and European countries in future studies, including other postsoviet countries. National cultural context matters for organizational studies including cultural factor. This fact can determine that the same phenomenon can be perceived differently considering national cultures lens. Moreover, the difference between the Polish and US sample regarding company size may have affected the identified differences. This limitation should be considered when analyzing and applying the knowledge from this study. This is a good starting point for further research about tacit knowledge awareness and the sharing of small and large companies' differences. Moreover, in this study, "mistake acceptance" is perceived as a proxy for learning from mistakes. Indeed, learning is not possible if the source of learning is not accepted. Still, the obtained R 2 = 52% (Poland) suggests that some other variables are not included in this study but might be significant for the better understanding of gathering tacit knowledge from mistakes for Poland. For the USA (R 2 = 89%), the applied proxy seems to be quite accurate. This fact justifies further cross-country studies. Different factors might be focal to explain the phenomenon in national cultures. So, knowing them enables us to broaden the body of knowledge.
A new, exciting direction for further studies on organizational behavior naturally emerges based on the presented findings. That is, it is particularly important to identify all factors that may influence learning from mistakes, other than the abovementioned factors of supportive leadership and authentic learning culture, which are undoubtedly crucial. A question arises: "How exactly should rules to support learning from mistakes be created?" Learning from mistakes requires deep reflexivity as well as a climate of psychological safety that comforts the individual (Edmondson and Verdin, 2018;Frazier et al., 2017;Kurtessis et al., 2017). This study is based on knowledge workersa skilled group of employeesbut even for such groups, important factors, such as personal motivation, an open-minded attitude or the general capability of the particular individual to learn, may affect individuals' ability to learn from mistakes. In addition, Parker et al. (2020) noted that organizational reflexivity is not exclusively the individual's actionit is a co-created corporate practice within a specific organizational context. Therefore, it is essential to identify factors that support organizational learning from mistakes in different contexts. This proposed research direction is vital to organizational development and hence requires more in-depth qualitative and quantitative studies.

Conclusion
This study aimed to understand and compare how the mechanism of innovative processes in the IT industrythe most innovative industry worldwideis shaped in Poland and the USA in terms of tacit knowledge awareness and sharing driven by a culture of knowledge and learning, composed of learning climate and mistake acceptance. Empirical research based on the IT industry in Poland and the USA was analyzed using the structural equation modeling method. As a result of a risk-taking attitude and critical thinking, the IT industry in the USA is consistently innovation oriented. Specifically, external innovations are highly correlated with internal innovations. It was empirically demonstrated based on a true learning culture composed of learning climate and mistake acceptance. Moreover, the learning climate is an important facilitator for learning from mistakes. The novelty of the presented findings can be summed up by stating that this research delivered empirical proof that a high level of mistake acceptance stimulates a risk-taking attitude that provides a high level of tacit knowledge awareness due to critical thinking. Thus, this study revealed that true learning derives from mistake acceptance.
