The PMBOK is like the rules of basketball. You don't have to know the rules to play a good street game. But as the stakes get higher, as the organization gets bigger, and as you work your way into the pro Leagues, you'd better know what the rules are and how to play by them.
All our courses are compliant in both language and character with the PMBOK 3 rd edition (2004).
Good practice does not mean that the knowledge described should always be applied uniformly on all projects; the project management team is responsible for determining what is appropriate for any given project.
