Introduction
This study analyzes the best cross-cutting practices for successful new product development (NPD) based on a systematic literature review, in which we intend to observe new patterns related to the topic. Why is this type of analysis relevant at this moment? The growing evolution of the market imposes a greater flexibility from companies in the application of Cross-cutting best practices for NPD different strategies, methods and techniques that yield competitive advantage for their products (Cheng, Chen & Tsou, 2012; Rodr ıguez-Pinto, Rodr ıguez-Escudero, & Guti errez-Cill ab, 2012), considering the intensification of globalization and connectivity. While the quality of products increases, technological development has also been shortening distances, improving communication and reducing processing. Thus, customers have more access to a greater variety of products and services than in the past, which increases competition, differentiation and customization. Therefore, to develop a value proposition and a cost-benefit perception by aggregating differentiation factors, such as quality and innovation attributes, delivery time and connectivity, investment in new technologies for NPD is essential at the product and process level.
In this sense, the capability for identification and technological absorption, supported mainly by the level of organizational learning and available human and financial resources, becomes a determining factor for promoting competitive differentiation, based on the degree of technological differentiation. In this new scenario, it is necessary to consider that competition is no longer limited to companies. Corporate networks and supply chains are responsible for the creation of a complex business environment globally, in which companies are compelled to collaborate to create competitive differentiations and technological integration; this new dynamic, therefore, affects practices related to NPD (Flynn, Huo, & Zhao, 2010;Koufteros, Rawski, & Rupak, 2010).
Thus, identifying and cataloging NPD practices have been the subject and purpose of several studies over the past years (Cooper & Kleinschmidt, 1995;Griffin, 1997;Carrizo-Moreira & Leonidivna, 2014;Boehe, Milan, & de Toni, 2009;O'dwyer & Cormican, 2017). These studies aim at understanding the variables that positively influence the process. Furthermore, as far as research on NPD consolidated, meta-analysis approaches also contributed significantly to the understanding of the critical success factors of NPD and innovation in general over the last decade, such as the approaches by Montoya-Weiss and Calantone (1994), Henard and Szymanski's (2001), Chen, Damanpour, and Reilly (2010), Crossan and Apaydin (2010) and Evanschitzky, Eisend, Calantone, and Jiang (2012). Evanschitzky et al. (2012) mentions a relevant finding in the NPD field; the author affirms that the importance of critical success factors declines over time as new theoretical approaches emerge and as these practices begin to become more known globally thanks to benchmarking. Therefore, within the NPD field, it is expected to find cycles of renewal of the practices. An important characteristic to be observed in studies on NPD practices is that they depend on and need to be contextualized and understood by considering the business segment, company size, national culture and even the level of internationalization. This is the reason why one finds in the literature a diversity of practices that positively affect the performance of NPD. Therefore, with the evolution and new configuration of the business environment, mainly due to the need for digital transformation (Zapata, Berrah, & Tabourot, 2020), there is a need to identify the patterns of practices mapped by literature while considering the dynamics of NPD in different business segments. Therefore, considering such context and due to the theoretical gap exposed, our research identifies the main crosscutting practices associated with NPD, in addition to determining new patterns.

New product development practices
According to Buyukozkan and Feyzioglu (2004) and Zabala-Iturriagagoitia (2017), new product development can be understood as transforming a market opportunity and considerations about a product technology into a product available for sale. Thus, in order to achieve this transformation, it is necessary to integrate knowledge and activities in marketing, engineering, operations, among others; a good performance in NPD depends on the combination of resources, capacities and skills existing in the company in the form of best practices (Tai, 2017;Woschke & Haase, 2016;Song & Parry, 1997;Verona, 1999). Therefore, this multidisciplinarity engenders particular characteristics of research, and it is necessary to systematize the different perspectives of analysis in this new value chain (Carrizo-Moreira & Leonidivna, 2014), which tends to expand the inventory of practices in the literature. Therefore, academics and NPD practitioners are interested in analyzing NPD practices because identifying a practicea technique, a method, a process or an activitythat is capable of delivering a new product more efficiently and effectively could be the difference between success and failure of the product and the company (Barczak & Kahn, 2012). Cooper (2019) points out that, globally, approximately 40% of new products fail in the launch; thus, the constant identification and updating of NPD practices become necessary.
NPD practices are organized in a few dimensions. Barczak and Kahn (2012), for instance, conceptualize the NPD in seven different dimensions of performance according to their role in the fields of strategy, research, commercialization, process, organizational environment, organizational culture, metrics and performance measurement.
In this sense, several studies focus on the themes presented by these dimensions, among which are knowledge management (Li, Pehlken, Qian, & Hong, 2016;Jia, Kang, & Gao, 2016), market strategy (Chao & Chen-Hao, 2015;Haverila, 2010), project strategy (Yang, 2012) and interorganizational strategies (Yan & Azadegan, 2017) as success factors for NPD. From a systemic approach, Cooper (2019) revisited the successful drivers of NPD and organized NPD information in a structure with three levels. These three levels explain that NPD success is a function of the individual drivers of the project, of strategic organizational drivers of the business and of the adopted system and process drivers. This view denotes the multidimensional approach of the NPD field. Furthermore, it indicates the approach of agile methods with greater emphasis on the exchange of information between customers and suppliers seeking greater speed in comparison to the initial linear models of NPD ( Figure 1). Evanschitzky et al. (2012), when updating the meta-analysis of Henard and Szymanski (2001) based on the practices described in Figure 2, identified an important finding, which is the effect of time on NPD best practices. There is evolutionary evidence that best practices may lose their effect size over the years as they become known and the business environment changes. Furthermore, culture emerges as a key moderating factor, in which countries with greater risk aversion have better performance in NPD, and individualist countries, with a low capacity for collaboration, present a worse performance.
When comparing the most recent models, e.g. the one developed by Evanschitzky et al. (2012) based on Henard and Szymanski's (2001) and the one of Cooper (2019), one identifies a few similarities concerning NPD practices; however, at the same time, such comparison indicates a new managerial problem, namely the number of variables and the complexity of the models for NPD managers.
As resources become scarcer in companies, there is an increasing need to prioritize them, and issues about which variables are more explanatory for NPD variability turn into an opportunity for investigation. Each practice variable translates, in managerial terms, into the need for resource allocation, know-how and experience curve. Therefore, it becomes necessary to advance in the understanding of more strategic and systemic decisions about NPD, whose allocation of resources implies direct and indirect impacts on the entire system.
One of these approaches refers to the capability concept, as investigated by Zawislak, Fracasso, and Tello-Gamarra (2018): companies can obtain innovative capacity, even in different technological intensities, as long as they balance their technological, operational, managerial and transnational capabilities. This approach is especially critical in the case of Brazilian companies, which, in general, are not provided with the same level of resources as companies investigated in international and more developed scenarios. Therefore, this analysis is extended to emergent countries.
According to Evanschitzky et al. (2012), it is necessary to understand the NPD from a cultural perspective, in which the availability of resources is asymmetric not only among   Practices for NPD development countries but also among the different types of business segment. Even in Brazilian cases, one finds divergent findings, as in the study of De Toni, Milan, and Reginato (2011) and Tumelero, Santos, and Plonski (2012); the explanation for such mismatch is attributed to the sectors analyzed. In the latter study, intensive high-tech sectors are usually related to different kinds of relationship with universities (Costa, Porto, & Plonski, 2010), which was not identified in the first case. These elements justify the need to evaluate NPD practices in recent articles of greater scientific relevance, identifying new transversal standards to the segment of activity.

Method
We adopted a quantitative approach to our study with exploratory features. As research strategy, we carried out a systematic review approach, in which a few patterns were identified. The Web of Science and Scopus databases were selected as data sources, considering the CAPES CAFe system. These databases were chosen for their high coverage in terms of worldwide reach, expanding the search results (Gusenbauer & Haddaway, 2020;Meho & Yang, 2007;Falagas, Pitsouni, Malietzis, & Pappas, 2008). As query operator, the term "New Product Development" was applied, proceeding with the selection of articles before 2018, in English, and without restricting the area. The decision to apply such operator was related to the expansion of the range of studies, aiming at a more comprehensive identification of different types of practices. From this consultation, we selected the articles according to the following criteria ( Figure 3). The articles selected were organized in an electronic spreadsheet according to the following variables: (1) name of the article, (2) issue date, (3) researched segment, (4) practice analyzed and (5) relationship with the NPD identified based on the observation of the models and hypothesis testing. Considering that the research aim was not to provide a bibliometric analysis in which the frequency of publications by authors or journals is evaluated, such variables were not considered in our study. Thus, as the article was analyzed according to the above-mentioned stages and the variables identified, the new information was reported in the table. The final structure is shown in Figure 4; at a first level, the practice was reported, and at

Step Procedure

1
The authors classified the articles in order of relevance, thus understanding the level of citation and adherence to the keyword. In this way, the articles selected are the most relevant when consulted the term "New Product Development" from the classification of the relevance of the bases, which considers citations and views concerning time. With this approach, there is a selection based on the level of the relative importance of the selected works to the great NPD theme.
2 Based on this classification, the title and abstract were analyzed, in the sequence provided by the bases: if the article expressed in the title or abstract a link to terms related to the NPD, such as "best practices/strategies", "innovation", "critical factors", "NPD success", among others. The authors selected the articles for the database for further identification of the NDP practices presented in the documents.

The aim was to identify in the author's research conclusions in terms of the positive or negative role of such practices in NPD performance.  Categorization structure for analysis a second level, the practices were categorized to standardize the nomenclature. When several practices were observed, they were identified for a secondary analysis and traceability.
The data collection was conducted based on these criteria; 50 articles were allocated to the Web of Science and the other 50 to Scopus. Concerning the periodicals that publish research articles, the selected publications were published in major journals, such as Journal of Product Innovation Management, Industrial Marketing Management, Technovation, Journal of Business Research, Long Range Planning, International Journal of Technology Management, International Journal of Innovation Management, Research Technology Management, R&D Management, among others. We emphasize one more time that the aim of our article is not to provide a bibliometric analysis in which the panorama of the area is approached; our research aim is, however, to identify new standards related to best practices by using this method. After the organization of the database, we carried out an analysis seeking to identify patterns and categories posteriori.

Results and discussions 4.1 Categorization and analysis of the practices identified
From the analysis of the articles, we identified the following categories related to the practices that are positively associated with NPD, as shown in Figure 5. Table 1 presents the result of the analysis, and, considering the multifunctional nature of NPD, it is possible to observe the occurrence of several practices. Among these practices, however, there are a few patterns. The higher incidence found is in the analysis of integration practices at a horizontal level (suppliers and customers), as well as at a vertical level (strategic alliances). Therefore, three categories (i.e. 7% of the total) correspond to 30% of the articles, which indicates that the authors should focus the analysis on them.
Another relevant finding we identified (Table 2), which provides an overview of the publications over the period analyzed, is that the integration of suppliers and customers, as well as strategic alliances, are topics that have been gaining research interest overtime. There is a trend toward the emergence of some practices that have not yet been studied. Some NPD practices, such as sustainability, marketing and the role of design in the process of developing

Patterns identified: discussions on integration capability
After the gathering of the 100 most cited and published articles in international journals on NPD practices, we conducted an analysis to organize their categories concerning the best Cross-cutting best practices for NPD practices that influence NPD. The patterns found present an emerging issue for discussionintegration capabilityaccording to the following aspects: (1) the three most cited practices in these articles (7% of the NPD practices account for 30% of the articles analyzed) are related to integration, (2) the positive relationship between integration practices and successful NPD, as discussed in Section 4.1, (3) occurrence of these integration practices in different research environments, as discussed in Section 4.1 and (4) the distribution of these integration practices over different periods of time (Section 4.1, Table 2). The findings suggest and support the proposal of integration with suppliers, customers and strategic alliances as a set of structural and transversal best practices for the development of new products. It is important, however, to distinguish integration and from the capability for integration. For Johnson and Fillipini (2013), the application of integration practices, whether internal (where the company seeks to integrate its areas and processes of marketing and sales, product/engineering development and operations) or external (such as connectivity with customers and suppliers during the development) is essential to NPD success, considering the necessary multidisciplinarity. However, the authors point out that the adoption of integration practices does not always lead to better performance (for example, too much functional collaboration can have a nonbeneficial effect due to the specialization of and focus on internal activities); in order to understand the reason that lies behind such argument, the authors introduce the concept of integration capabilities as mediators between NPD integration and performance practices. In line with Winter (2003), capabilities in essence are distinguished from operational and short-term processes (considered ordinary capabilities) and are considered dynamic higher-order capabilities, which they allow the organization to expand, modify or create ordinary capacities, reconfiguring itself. Thus, in accordance with such concept, copyable integration practices are not the ones that become the source of success for NPD, but how they are composed to become real organizational capabilities. This implies, in practical terms, the company's ability to dynamically generate value and change in its relationship with suppliers and customers (Tzokas, Kim, Akbar, & Al-Dajani, 2015). To sustain and reconfigure the operational procedures necessary to maintain these relationships over time as environmental changes occur is a dynamic process, considering that capabilities are associated with the ability to adapt and change. NPD managers face up to the challenge of the duality exploring core capabilities versus exploring organizational core rigidities: when the latter are higher, the capacity for change is compromised and consequently the performance of NPD (Leonard- Barton, 1992). Generally, a level of integration can exist between supplier and customer, but in a rigid way with no room for adaptations. A valid example is vertical integration contracts. In other words, there is an integration practice but not necessarily a dynamic integration capacity. If some changes in the environment require an adaptation in the way this integration takes place (contracts, communication flows, informational integration, among others), integration will distinguish from integration capability. Thus, the capability goes beyond the procedure itself as it also incorporates the capacity for change, especially in response to turbulent environments.
Thus, the integration capability is a central issue for new product development. This perspective demonstrates that when an organization establishes a higher and better level of integration in the horizontal (suppliers and customers) and vertical (strategic alliances) dimension, there are better chances to enhance NPD, and consequently a more effective product launch, in addition to risk sharing in alliances (Sivadas & Dwyer, 2000). A possible explanation for the association between integration capacity and NPD success is that product development should be the creation of new knowledge at the organizational level; it deals with the boundaries where knowledge is generated and structured differently in distinct organizational functions (Amaya Rivas, Cheng, & Yang, 2020;Carlile, 2002). Thus, in order to integrate it, it is necessary to understand that this differentiation exists. Considering the necessary combination of knowledge in phases of the entire process, whether marketing, technological, management, tacit or explicit knowledge, the capability for integration becomes decisive to generate the necessary conditions to accelerate or create barriers to the process. It occurs due to the involvement of companies, suppliers, customers and alliances, such as universities and research and development centers, in building and combining knowledge in the NPD process.
The ability to integrate is also fundamental since it enables the complementation of competencies through the combination of external and internal knowledge (Hoang & Rothaermel, 2011) and through resources and assets that the company lacks internally through the interface with external knowledge, which enables the feasibility of new development projects (Ferraris, Devalle, Ciampi, & Couturier, 2019) and promotes competitive advantage (Rothermel, 2001). Thus, many of the successful NPD practices cited in the literature can be built based on integration, where competence is acquired through a synergy of efforts.
Another emerging practice to be discussed herein is co-creation. Considering the importance of integration capability, it enables the co-creation capability in the NPD context at its different stages (Hoyer, Chandy, Dorotic, Krafft, & Singh, 2010). Although co-creation is not directly observed among the most cited articles identified, there is a growing interest in the subject concerning NPD, as shown in Figure 6, which can be explained by the fact that it is a more recent theme in the area.
According to the co-creation concept, it is necessary to differentiate the role of co-producer from co-creator; while the first refers to the involvement in the productive process of a good or service, the second involves more active participation in this value chain (Chathoth, Altinay, Harrington, Okumus, & Chan, 2013;Etgar, 2008). The integration with customers, which enables the exchange of information regarding their specific needs in the customization of products, can lead to better chances of success in product development; in addition, customers must actively participate in the creation process and not only in satisfaction surveys. This approach expands the ability to identify demands and validates a value proposition, if the company has the necessary absorptive capacity for such (Morgan, Obal, & Anokhin, 2018). Likewise, even if integration enables the co-production or higher involvement, it is necessary to distinguish this continuum. From a different perspective, to meet this demand, the capability for integration (involving co-creation with suppliers in purchase or distribution channels) is critical to combine new knowledge. In this case, specifications, materials, delivery capacity and aspects inherent to product development must be handled more efficiently and involved in different stages of NPD, especially in turbulent scenarios (Lawson, Krause, & Potter, 2015;Luzzini, Amann, Caniato, Essig, & Ronchi, 2015;Petersen, Handfield, & Ragatz, 2005). From a company perspective, it requires attitude to overcome barriers to information sharing, with positive effects for NPD (Ragatz, Handfield, & Scannell, 1997). Thus, higher capability for simultaneous integration between suppliers and customers becomes a structuring practice for the success of NPDs and starts to enable co-creation capabilities. This relationship with co-creation at the horizontal level is in line with the findings of Moon, Johnson, Mariadoss, and Cullen (2018), in which the involvement of suppliers and customers in the co-creation layout is positive for NPD.
At the vertical level, integration and co-creation can be observed in strategic alliances. The NPD process involves phases such as identifying opportunities (generating ideas and identifying market needs), design and development (positioning, segmentation, engineering and market studies), testing (product and pre-launch), market introduction and life cycle management. Therefore, these alliances can also be very relevant to the success of NPD since there is evidence of the positive effects of coopetition on NPD (Bouncken, Fredrich, Ritala, & Kraus, 2018;Estrada, Faems, & de Faria, 2016;Gerwin, 2004;Gerwin & Ferris, 2004). For example, the ability to integrate a partner to a company located in different time zones can accelerate the development of the project for the market as it enables teams to work uninterruptedly in the development process. Likewise, in the design and development phases, the collaboration and combination of resources of these organizations via co-creation is also critical to accelerating NPD; it occurs through the integration of creative and technological human resources. At a different level, the ability to integrate and co-create with universities and research centers allows new product, process and system technologies that also enable higher value generation for the new products developed. Accordingly, the need to ensure that there is a capacity for change on integrations established with customers, suppliers and strategic alliances emerges, which enables the co-creation capability.

Relationships between integration, co-creation and ICT's
Since the capability for integration is dynamic, that is, it relates to adaptation, it is understood that the capability for change is directly related to the identification, absorption and interpretation of new information, and especially to feedback. If there are no conditions to perceive signals from the environment, i.e. to capture these signals through data, convert them into information and create knowledge and meaning, the capability for change and response is compromised. In the context of NPD, this relationship can occur through the observation of market trends, consumer behavior, technological trends and trends in competitors' moves. Co-creation capability anticipates the information that is generated for the company and can be exponentially expanded in uses of crowdsourcing approaches for NPD (Poetz & Schreier, 2012), or even design thinking. That is, instead of using intermediaries between the company and the customer, such as research institutes through the generation of market intelligence to identify customer needs, the co-creation capability accelerates this generation of information directly to the company, accelerating the NPD process, and consequently the response time to changes. Still, co-creation, insofar as it assumes an interaction, also presumes a relationship of trust based on exchanges and participation in the construction throughout the process. This way, even though the integration capability enables co-creation practices, co-creation also supports the strengthening of the integration.

Through product validation information, identified throughout the process, changes can be processed, analyzed, decided and implemented. The disorganization of this flow of information and communication leads to critical failures in the development of new products. Therefore, at this point, there is an understanding that the capabilities of applying information and communications technology (ICT) to the integration processes with suppliers, customers, and alliancesaiming at co-creationbecome structural elements to build the capabilities for change, especially in contexts of market pull or technology push. The positive benefits of ICT on NPD occurs in the fields of information flow, transparency, organization, collaboration, language and connectivity (see Figure 7).
Hence, Raymond, Uwizeyemungu, Fabi, and St-Pierre (2018) and Mauerhoefer, Strese, and Brettel (2017), when analyzing the impact of ICTs on the performance of NPD, identified that the impacts are positive when constituted as capabilities. This perspective means that information systems do not simply standardize routines creating limitations. They enable the ability to change based on the promotion of connectivity and anticipation, in addition to the involvement with senior management. Thus, the pattern identified in the publications leads to an understanding: among so many managerial decisions for NPD success, considering the number of factors already investigated in literature, there is a need to prioritize the construction of the integration and co-creation capabilities, which are enabled by ICTs. Thus, as far as better integration with suppliers, alliances and customers is promoted, a more structured and cohesive flow of information and communication shall occur, which brings positive impacts for NPD. Especially in the context of innovative product and service development, where stronger multidisciplinarity and a network of actors are needed, such perspective is required. Moreover, the construction of an organizational memory is critical for creativity and NPD (Moorman & Miner, 1997). Considering that the

Information Flow
The Integration Capacity can be understood as also involving the ability to integrate the flow of information, given the quantity and quality of information that circulates between suppliers, customers, and alliances in NPD processes, investments in ICT enable the organization to assign meaning to the entire data chain generated throughout the process together with the communication of the multifunctional parties involved (Tai, 2017). For Zhan et al. (2017, NPD is a matter of big data, and the ability to deal with internal and external knowledge big data is positive for innovation success, as also observed by Tan and Zhan (2017).

Transparency, Organization and Collaboration
From the transparency of information, the perception of integration between the parties involved is built. The collaboration between these actors throughout the development of a new product can be influenced by their level of exchange of useful information inherent to the specific stages of NPD. It can be observed that in scenarios of disorganization of information and communication flows throughout the NPD where there is a higher level of parties involved, there are impacts on the success of the project.

Language
Integration, therefore, depends on collaboration, which also involves the construction of a common language in the exchange of information. In this aspect, ICTs can also help in the uniformization of this language, from dictionaries, libraries associated with the NPD, and metadata of parameters, building greater understanding and systematization of knowledge, as well as communication between these various parties in the NPD process. A critical point concerning the development of new products concerns the decision making information about the progress of the project, whose ICTs can support in its registration, evaluation, and communication process.

Connectivity
Consequently, ICTs, through their interface, enable connectivity from increasingly agile co-creation mechanisms, whether, on the client's side, suppliers, or strategic alliances, also involving Universities, as the flow of information of demands and possible solutions begins to streamline the processes of identifying opportunities between client and company. With the convergence of information between the requirements between company and suppliers, between the combination of design and technology elements with strategic alliances, ICT's enable a co-creation capacity, which therefore enables greater Integration Capacity, which is central to the Development of New Products.

Figure 7.
Relationship between NPD and ICT development of a new product occurs through the generation of new knowledge, involving scientific and technological expertise, the processes must enable a better knowledge combination based on the generation of data and analysis. Thus, by merging the findings of our research on integration capability with the emerging discussions about co-creation and ICTs, it was possible for us to establish a few relationships. These aspects, therefore, can lead to higher success in NPD and its capability for innovation (see Figure 8), thus constituting basis or structuring transversal factors. These basic or structuring factors are combined with the other practices identified in the literature, which are more or less dependent on the segment in which the business operates, size and level of internationalization. This framework indicates the networking capability (connecting with external partners) and networking ability (the ability of NPD managers to work with stakeholders outside the company), which are both positive for DNP (Mu, Thomas, Peng, & Di Benedetto, 2017). Studies point out curvilinear effects between the number of partners and performance (Mishra, Chandrasekaran, & Maccormack, 2015), which demands new skills to deepen the quality of partnerships to suppress this effect (Kurpjuweit, Reinerth, & Wagner, 2018). This type of model may be appropriate in turbulent scenarios, where companies have limited resources to invest in all internal DNP practices, i.e. when companies pursue complementary assets.

Final remarks and suggestions for future studies
Our study presented a research strategy based on the systematic review method, in which the 100 most cited articles published in international journals were analyzed, identifying the categories of practices associated with NPD. One pattern found is that, in ours sample, three categories (7% of the total) represent 30% of the articles identified. The construction of our framework led to the conclusion that the practice of integration is one of the structural and cross-cutting best practices for NPD. Thus, this paper discusses the importance of integration capacity for NPD, which differs from integration per se and, according to Johnson and Fillipini (2013), would become increasingly necessary for organizations to overcome NPD expectations in terms of product performance and time. However, as the integration capability becomes a critical success factor, new capacities are increasingly required, especially in turbulent environments, where the capabilities for change and knowledge sharing in NPD supported by ICTs (Gao & Bernard, 2018) are increasingly necessary. (Pavlou & El Sawy, 2006, 2010.
Such results indicate, therefore, that the improvement of NPD performance of an organization must essentially rely on the search of an integration capability and, consequently, of collaboration at the vertical and horizontal level, involving suppliers, Cocreation layer with suppliers, alliances and customers, sustaining integration dynamically ICT layer to organize information flow, network involvement and information availability in real time Internal integration of multifunctional teams New Product Development Process Best NPD Practices -Contextualized in Market Segment Figure 8. Cross-cutting best practices for NPD success customers and alliances, such as universities and research institutes. Especially in the current context, in which advantages are increasingly built based on innovation ecosystems, the capacity for integration becomes increasingly essential since it also enables the complementation of competencies and resources for the development of new products. According to this logic, when such integration processes become critical for NPD performance, integration must be created as a dynamic capabilityi.e. a capability that enables adaptations to the environmentthrough co-creation processes, where the active proximity to customers, suppliers and alliances throughout the NPD stages expands the possibility of interaction, building trust and reciprocity, contributes to a greater capacity to build knowledge, validates the value proposal throughout the development and complements skills and resources. However, with the increase in the complexity of actors and information generated throughout the process, investments in ICTs, as a way to ensure agility, flexibility, speed and transfer of information and knowledge, become critical capabilities of organizations pursuing better NPD performance and successful innovations, especially in global environments.
Therefore, our study contributes to literature with the proposition of the theoretical framework in NPD, sustaining the integration capability as a cross-cutting and transversal practice in NPD. This implies integration practices at the vertical and horizontal level, which relates to co-creation processes with the support of ICTs. Further investigations into the effects of these variables can indicate a relevant research agenda in the field. In managerial terms, the results of the systematic review indicate that investments and prioritization in the ability to integrate at the vertical and horizontal level can increase NPD's success rate, even though such factors are not the only ones responsible for this result. Considering the structural and transversal factors mentioned herein, managers could prioritize investments to design, build or improve their NPD model based on such foundations, assessing their integration capability, co-creation capability and assessing which ICT technologies are more suitable to support the NPD process adopted by the company. NPD also involves a human component as it is a process of creating and building knowledge, which requires the recruitment of cognitive skills. Thus, the pattern found in this research contributes to these theoretical and managerial dimensions, which enables the development of future studies based on the model proposed in our study, as well as the development of a maturity model at the integration level for NPD considering its validation.
Although the objective of the study was not to describe the panorama of the area from a systematic review approach, but to identify new patterns through this process, it is possible to consider the sampling chosen a limitation of the study. We suggest, therefore, the expansion of the sample and the incorporation of other databases in future studies. In addition, considering we only chose the "new product development" operator, we suggest for future research to advance our findings by adding complementary operators and to analyze NPD relationships in different segments, given the diversity of practices identified. Future studies are also recommended to analyze the types of integration from a strategic orientation approach, especially in family-controlled companies (De Massis, Frattini, & Lichtenthaler, 2013;De Massis, Frattini, Kotlar, Petruzzelli, & Wright, 2016). Moreover, the proposed framework can support both theoretical and managerial agenda regarding NPD and digital transformation.
