The PM2 methodology guide provides an introduction to the PM2 project management methodology developed by the European Commission. It describes the key elements of the PM2 methodology including the project lifecycle, roles, and processes. The guide is intended to help project managers and teams understand and apply the PM2 methodology. It is maintained by the Centre of Excellence in PM2 which supports the use of PM2 within the European Commission and other EU institutions. The Open PM2 initiative aims to make the PM2 methodology more widely available to organizations outside the EU as well.
