This document provides an overview of a presentation given by Traian Kaiser of XING AG on paradigmatic shifts in project management. It discusses how pioneers in agile and lean project management have introduced new ideas that challenge traditional project management approaches. Key shifts discussed include moving from negotiated contracts to collaboration and trust; focusing on customer requirements rather than predefined scope, budget and schedule; empowering self-organizing teams rather than top-down management; and taking a value stream view beyond individual departments. The presentation argues that these changes better enable teams to adapt to changing needs and continuously improve results.
