This article compares the changes from the PMBOK® Guide 2000 Edition to the PMBOK® Guide Third Edition (2004 Edition). Its purpose is to review the historical perspective of the Guides with reference to their process inputs and outputs. In particular, there have been conceptual changes that should be explained for the benefit of the project management community.
As a result of this research, as well as making suggestions for future editions, we strongly recommend improvements to the 2004 Edition by way of an amended update. This should be done in two stages. The Project Management Institute should move to correct invalid figures as First Stage Improvements, to avoid harm to the reputation of the Guides. This should be followed closely by a Second Stage project of improvements along the lines described in this paper.

I have read the main content of this analysis. The viewpoint of the author is very clear and reasonable.The content added to the PMBOK third edition does not mean the improvement of PMBOK,on the contrary way, compare it with PMBOK 2000, we are all confused by the detailed input and output,the relationships between the processes.
