PMO - necessary evil or efficiency booster?

Living in a fast-changing business world presents us with increasingly unusual challenges and companies that want to thrive need to be more agile in responding to change to become market leaders. They need to quickly decide on the right projects to choose and be capable of delivering them in the right way.

Project managers and PMO are the force within the organisations that drives the responses to change - or that carries them on their back.

Based on the cases from professional experience, we looked for answers to these questions. The discussion shedded some light on how companies see and understand the role of PMO.
