PRINCE2 (Projects in a Controlled Environment) is a structured project management method based on experience drawn from thousands of projects – and from the contributions of countless project sponsors, Project Managers, project teams, academics, trainers and consultants.
The 2009 edition of Managing Successful Projects with PRINCE2 represents an evolution of the previous manuals. The basic methodology remains, but by building on comments from users, this new manual aims to be more accessible and easier to tailor for specific individual needs.
Representing a revolution, the new Directing Successful Projects with PRINCE2 is aimed at supporting the senior manager responsible for a project, specifically those managers undertaking an executive role on a project for the first time. (Source: http://www.best-management-practice.tv/ )
