Project Management Offices (PMOs) are not etched in stone. Several formal surveys show that the average life-span of a PMO is about two years, and even during those two years, they continually evolve. PMOs are not stable structures but rather temporary arrangements with a somewhat short life expectancy. So, what does that mean to you? Identifying the Forces Driving Frequent Change in PMOs answers this question for both researchers and practitioners. Seventeen case studies and 184 responses to a questionnaire provide the foundation for this three-year research effort focused on the organizational change process surrounding the transformation of a PMO. Results show the temporary nature of PMOs and reveal that significant changes in PMOs can be associated with an organization's internal and external environment. Why do PMOs change? What are the drivers? How does the change happen? Is there a dynamic change process? What is changing? What are the characteristics or functions that are changing? Is There a pattern of change? Identifying the Forces Driving Frequent Changes in PMOs is a major contribution to the theoretical foundations of project management and a useful guide for project management practitioners and upper management executives in their implementation, remodeling, and management of PMOs.
