With increasing concerns regarding the performance of public procurement, especially concerning timely delivery, this study aims to investigate the predictive role of sustainable supplier selection (SSS) in enhancing lead-time performance in public procurement, while also examining the moderating effect of relational capability.

The study collected primary data from 179 accredited public organizations in Tanzania through structured questionnaires and used partial least squares structural equation modeling for data analysis.

The results reveal that SSS and relational capability influence lead-time performance in public procurement. Regarding the moderating effect of relational capability, the study establishes that relational capability strengthens the influence of SSS on lead-time performance. Therefore, based on the collected data from surveyed public organizations, relational capability positively moderates the relationship between SSS and lead-time performance in public procurement.

The study offer valuable implications for public procurement practitioners, academics and other stakeholders. Public organizations should consider contemplate integrating sustainability aspects into supplier selection processes. Furthermore, the study contributes to advancing efforts toward achieving sustainable development goals (i.e. SDG12) within Tanzania, particularly by advocating for sustainable public procurement practices aligned with national policies and priorities.

This study not only enhances the understanding of public procurement performance by investigating lead-time improvement, incorporating considerations of SSS and relational capability, but it also offers empirical evidence of the moderating role of relational capability within the unexplored Tanzanian context.

This study examines the moderating role of information sharing on the effect of lead-time management on the performance of firms in the Zimbabwean motor industry.

Data were collected using Likert-based structured questionnaires from a sample of 105 employees in Zimbabwe. In addition, Pearson Correlation, Linear Regression and Moderation Regression analysis were employed to test the relationship between study variables.

The study found that fixed lead time, preprocessing lead time, processing lead time and postprocessing lead time significantly influence the performance of firms in the motor industry. The results also demonstrate that information sharing moderates the effect of lead-time management on firm performance in the motor industry.

Firms in the motor industry should establish long-term relationships with their suppliers and implement effective communication channels for timely and frequent information exchange regarding production schedules, inventory levels, quality standards and potential disruptions.

The current study aims to contribute to the scientific discourse on lead-time management, information sharing and performance in the motor industry. Furthermore, it extends knowledge on the performance of the motor industry in the African region.

This study aims to examine the effects of organizational polychronicity on individual adaptive performance. Drawing on conservation of resources theory and the perspective of individual differences in pressure perceptions, this study develops a conceptual model to test the mediating role of time pressure and the moderating role of trait regulatory focus in the relationship between organizational polychronicity and individual adaptive performance.

A three-wave survey was conducted to investigate a sample of 591 employees who engaged in innovative activities in China. The hypotheses were tested using hierarchical multiple regression and bootstrapping.

The results show that organizational polychronicity is negatively related to individual adaptive performance via time pressure. Promotion focus weakens the positive relationship between organizational polychronicity and time pressure and the mediating role of time pressure, while prevention focus augments the positive relationship between organizational polychronicity and time pressure and the mediating role of time pressure.

This study reveals the mediating role of time pressure in the relationship between organizational polychronicity and individual adaptive performance, as well as the moderating role of trait regulatory focus in this relationship, thereby deepening our understanding of organizational polychronicity from both a theoretical and a practical perspective.

The relationship between variation in time perspectives and collaborative performance is scarcely explored, and even less is known about the respective mechanisms that lead to varying task performance. Thus, we aim to further the literature on time perspectives and collaborative performance, shedding light on the underlying behavioral patterns.

We report a quasi-experiment analyzing the impact of past, present and future orientation variation in dyads (N = 76) on their quantitative and qualitative performance when confronted with a simple incentivized creative task with constraints. Subsequently, we offer a qualitative analysis of comments given by the participants after the task on the collaboration.

Results indicate that a dyad's elevation of past orientation and diversity in future orientation negatively affect collaborative performance. At the same time, there is a positive effect of elevation of future orientation. The positive effect is driven by clear communication and agreement during the task, while the negative effect arises from work sharing and complementation.

This study provides insights for organizations on composing individuals regarding their temporal focus for collaborative tasks that should be executed rapidly and require creative solutions.

Our study distinguishes by considering the composition of past, present and future time perspectives in dyads and focuses on a creative task setting. Moreover, we explore the mechanisms in the dyads with a substantial elevation of/diversity in future orientation, leading to their stronger/weaker performance.

The study objective was to understand what components of organizational culture and capability combined with analytic skillsets are needed to allow organizations to exploit real-time analytic technologies to create supply chain performance improvements.

The authors relied on information processing theory to support a hypothesized model, which is empirically tested using an ordinary least squares equation model, and survey data from a sample of 208 supply chain executives across multiple industries.

The authors found strong support for the concept that real-time analytics will require specialized analytical skills for the managers who use them in their daily work, as well as an analytics-focused organizational culture that promotes data visibility and fact-based decision-making.

Based on the study model, the authors found that a cultural bias to embrace analytics and a strong background in statistical fluency can produce decision-makers who can make sense of a sea of data, and derive significant supply chain performance improvements.

The research was initiated through five workshops and presentations with supply chain executives leading real-time analytics initiatives within their organizations, which were then mapped onto survey items and tested. The authors complement our findings with direct observations from managers that lend unique insights into the field.

The present research aims to investigate how lean project management (LPM) and agile project management (APM) affect project performance outcomes in the construction sector in Jordan. This study focuses on six key project performance outcomes, namely cost, time, quality, client satisfaction, innovation and responsiveness.

The present study employed a quantitative approach to achieve the research objectives. Accordingly, a multi-item survey questionnaire was prepared to gather data from 392 project managers from construction companies in Jordan. The study’s model showed acceptable levels regarding reliability, validity, fit indices and discriminant validity. In order to test the hypotheses of this study, path analysis was employed using Amos 24.0 software.

LPM demonstrated a remarkably high positive impact on cost performance. It also positively affected quality performance and client satisfaction. However, LPM insignificantly affected time, innovation and responsiveness performance measures. On the other hand, APM showed a notably high positive impact on innovation and responsiveness. The findings also revealed that APM positively impacted quality performance and client satisfaction. In addition, APM negatively impacted cost performance and insignificantly impacted time performance.

This study is one of the first comprehensive studies to empirically examine the impact of both LPM and APM on various project performance outcomes in the construction industry in the context of a developing country. It reveals some similarities and differences between LPM and APM with regard to their impacts on project management outcomes. The findings are expected to guide managers in selecting the appropriate project management approach based on the desired performance outcomes. Accordingly, it offers important implications for project managers in construction companies.

The purpose of this research is to study the impact of perceived adoption of Lean principles on operational performance in Lebanese pharmaceutical industries.

A quantitative method was implemented using a questionnaire that targeted 253 respondents working in eight good manufacturing practices (GMP) certified Lebanese pharmaceutical companies. Reliability analysis was performed using SPSS, and the research hypotheses were tested using regression analysis.

The results demonstrated that Lean principles positively and directly affected operational performance. It also positively affected operational performance factors of quality, cost and time. However, the analysis of each of Lean principles impact on operational performance cost was analyzed perfection, value, and value stream mapping (VSM) significantly increased operational performance. In addition, pull only positively augmented the cost reduction, whereas flow did not show any effects on any of operational performance’s factors.

In addition to enhancing operational performance, the positive effect of the perceived adoption of Lean principles on performance is also explained by managers’ efforts in studying the flow of actions in their processes to reduce wastes. To face uncertainty, training and building a workforce that is able to implement Lean principles, equipping this workforce with needed artifacts, and promoting a high-performance culture are crucial for the successful implementation of Lean principles.

Lean approach has become a major pathway of improvement especially in pharmaceutical companies. Few studies analyzed the impact of each of the Lean principles on the operational performance in companies that operate in era of uncertainty. Furthermore, the perceived adoption of Lean principles is under investigated in the Middle East in general and in Lebanon in particular.

The paper also proposed a novel conceptual model prescriptively guiding quick and long-term improvements in intensive manual workforce assembly lines. The article assists industrial decision-makers with subsequent turnaround strategies to ensure higher efficiency levels requested by the market.

The paper offers actionable findings relevant to other manual assembly lines utilising an intensive workforce looking to improve operational performance. Some of the methods and strategies examined in this study to improve productivity require minimal capital investments. Lastly, the study contributes to the empirical literature by identifying production levelling problems in a real context.

Certified B Corporations (B Corps) represent a prominent manifestation of applying stakeholder principles in practice by emphasizing social and environmental performance and striving to create value for all stakeholders. This paper aims to investigate an important question that has been unexplored so far in a vast body of literature on stakeholder management and fast-growing research on B Corps: does the timing of a B Corp’s certification impact the firm’s economic and social performance?

The research on the timing of obtaining B Corp certification is built around three intriguing puzzles: the impact of certification timing on a firm’s economic performance, social performance overall and social performance per stakeholder. In particular, the study examines the relationship between B Corp’s certification date and firms’ financial and social performance between 2017 and 2020.

Based on the data from 168 privately owned B Corps in the USA, the results of our study suggest that while there is no financial benefit associated with earlier certification, there are significant improvements in social performance. Yet, a firm’s social performance improvement is not uniform among its stakeholders.

This study explored the impact of B Corp certification’s timing on the firm’s economic performance within only three years, from 2017 to 2019. This limitation comes from the specifics of the PrivCo database. Measuring a firm economic performance over a longer period may benefit the research on B Corp certification’s timing and which can be a promising path for future research.

When it comes to practical implications, it is important that firms deciding to pursue a B Corp certification understand that certification may not result in an immediate financial impact. This practical implication, though, may need to be calibrated depending on the extent to which participating organizations publicize their certification.

Despite the growing popularity of B Corps in the USA and worldwide, it has been a black box when it comes to understanding when exactly firms should start to pursue B Corp certification to enhance their social value creation. Thus, this study is well timed to contribute to unpacking this black box by showing that the earlier a firm obtains B Corp certification, the more social value it would create. To the best of the authors’ knowledge, this is the only study to date that explored the social performance implications of timing to certify as a B Corp.

When it comes to practical implications, it is important that firms deciding to pursue a B Corp certification understand that certification may not result in an immediate financial impact. This practical implication, though, may need to be calibrated depending on the extent to which participating organizations publicize their certification.

This paper evaluates the risk-adjusted returns, selectivity, market timing skills and persistence of the performance of Nigerian pension funds.

Annual return data of 23 pension funds that operated in Nigeria between 2018 and 2022 were obtained from the National Pension Commission (PenCom). Risk-adjusted return was appraised using the Treynor ratio, Sharpe ratio and Jensen alpha, while the Treynor–Mazuy and Henriksson–Merton multiple regression models were applied to decompose selective and timing skills. Performance persistence was assessed using the contingency table and rank correlation models.

Evidence shows that pension funds deliver excess risk-adjusted returns and exhibit selective skills. However, the evidence does not support the presence of timing skills, and there is overwhelming evidence that good (bad) performance does not repeat.

An evaluation of the investment performance of pension funds is crucial for ensuring the financial stability of retirees, maintaining economic stability and making informed investment decisions. It serves the interests of pensioners, pension fund managers, regulators and the broader economy. Our evidence that pension funds generate positive excess returns is a departure from most of the literature on managed funds. We recommend that more Nigerians should leverage the pension fund industry to grow their wealth and prepare for retirement.

This study, to our knowledge, is the first to appraise all the key facets of the investment performance of pension funds in the Nigerian context.
