This paper analyses a longitudinal case study of organizational and human resource management (HRM) dimensions in the implementation of an approach to product development (concurrent engineering (CE)) in a multinational firm engaged in defence electronics. Most aspects of managing product development in CE are linked to people management. Yet in this case, other than project team structure, prescriptive HRM dimensions of CE received little attention in the implementation process. This failure to address the 'formal' prescribed HRM issues is explained by a multilayer analysis of the play of power and political lobbying among 'stakeholders' over time: the HRM function, key groups and individual managers. The implications of the failure to understand HRM issues in such new organizational techniques are addressed.
