Mitigating the impact of member turnover in information systems development projects

Team member turnover presents significant risks to the performance of information systems development (ISD) projects. While prior studies have identified various antecedents of turnover with the general objective of reducing its occurrence, turnover cannot be completely prevented in practice. This study examines practices for mitigating the negative impact of turnover when it occurs. Since ISD is knowledge intensive and turnover typically involves knowledge degradation, this study focuses on key practices for reducing such knowledge degradation, i.e., job enlargement, use of electronic knowledge repositories, and succession planning. Our model for explaining the effects of the practices, based on the human capital and organizational forgetting theories, is tested through a survey of 138 project managers of ISD teams experiencing turnover. The results indicate that the use of electronic knowledge repositories and succession planning reduce the negative effect of turnover on the project performance. In contrast, job enlargement does not have a significant mitigating effect. This study contributes to research by looking beyond the antecedents and prevention of turnover to understand how it can be managed effectively. The findings also offer pragmatic suggestions for alleviating the detrimental effects of team member turnover on the ISD project performance.
