One of the chief road-blocks to Scrum adoption levied to many PMI background project managers is that there is no reference to adaptive/empirical planning approaches in the Project Management Body of Knowledge (PMBoK). In fact, there does appears to be precident in the PMBoK already for “adaptive” management methodologies: “Rolling Wave Planning”. I saw this Craig Larman’s book Agile & Iterative Development: A Manager’s Guide, pp. 253-258, where he references: Githens, G. 1998. “Rolling Wave Project Planning”, Proceedings on the 29th Annual Project Management Institute 1998 Seminars and Symposium.
Craig notes that Rolling Wave is often recommended in RFPs, etc., but is widely misunderstood and disregarded in practice. Interesting stuff, that combined with DoD mandates for “Evolutionary” and “spiral” processes should help bridge the gap. We’ll see how long it takes for the rhetoric to catch up with practice.
