Purpose In the extant literature, the effect of outsourcing activities on the firm performance has been an area of interest for several decades; yet, the body of knowledge lacks a holistic view of this phenomenon. The potential outcomes of outsourcing and its impact on firm performance have not been aggregated in the literature. The purpose of this paper is to conduct a meta-analysis of 51 empirical results using 24 articles to examine the relationship between these variables and firm performance. The authors discuss the extant literature and examine which type of outsourcing has the greatest influence on firm performance. The authors also present the limitations and future opportunities. Theoretical and managerial implications are discussed to highlight which outsourcing functions would be fiscally beneficial for firms. Design/methodology/approach This paper takes a granular approach by looking at different outsourced functions in the both the manufacturing and service industry. Using meta- analysis, this paper combined the quantitative study data from several selected studies in an effort to increase power, improve the effect size and resolve the uncertainty about the effects of outsourcing activities on firm performance measures. Findings The authors found that outsourcing enhances the firm performance. When outsourcing functions were studied individually, only IT outsourcing had significant effects on firm performance in comparison to other forms of outsourcing. This might be attributed to the fact that IT outsourcing is less costly to implement in the organization compared with other forms of outsourcing. Originality/value This paper is the first paper that uses a meta-analytic approach to investigate the relationship between outsourcing and performance measures based on past empirical studies that have used both primary and secondary data.

PurposeThe purpose of this paper is to study project management performance measures by analyzing how training utility affects the relationships between mutual trust, social interaction and creativity as well as mutual trust, social interaction and flexibility in projects.Design/methodology/approachUsing training utility and organizational support theory, eight hypotheses were developed. Responses from 279 project management professionals in the USA were collected. The hypotheses were then tested using partial least squares (PLS) and regression with the PROCESS macro approach.FindingsThe results suggests that the communication environment indeed has an important role in fostering creative and flexible project managers. Additionally, the study shows that organizations can actively improve the influence of the communication environment on project management creativity through training efforts. Interestingly, these findings may not hold for project manager flexibility.Practical implicationsIn today's project management world, organizations need project managers who quickly adapt to changing project management scenarios. To do this, project managers need to be creative, generating new and novel ideas, as well as flexible when converting ideas into action. Organizations often possess large amounts of knowledge, and project managers rely on good communication practices to access this knowledge in response to the required changes in the project domain.Originality/valueThe study includes contributions to theory and empirical research in project management by analyzing the critical role training utility has on the firm communication environments and its outcomes. The study shows that organizations can take an active role by investing in resources to promote flexibility and creativity in projects.
