Abstract
By design, bodies of knowledge capture and influence best working practices. Gendered assumptions based on masculine cognitive styles are predominant in the Guide to the Project Management Body of Knowledge (PMBOK) [PMI. Project Management Body of Knowledge. Project Management Institute 1996]. This study investigates the assumptions and cognitive styles embedded in successful project managers’ discussions of their working practices. Both male and female project managers exhibit sophisticated skill in balancing masculine and feminine cognitive styles and attribute their success to “dancing in the white spaces” between the lines laid out by the PMBOK. This raises important questions about the role of the PMBOK in training and certifying project managers.
