This paper first discusses how the two most prominent project management bodies of knowledge see their relationships with general management. The PMBOK Guide (PMI 2004) very directly points out the importance of general management and allied topics (here called ‘Supporting’ topics) in managing projects. However, whilst it lists the latter in some detail, it does not elaborate on them, on the basis that they are already covered in the general management literature. Instead, the PMBOK Guide focuses on detailed expositions of its nine project management topics.
