Simplify Project Management?

Project management as structured through PMBoK is fairly complex. It involves four phases (concept, develop, execute, finish– CDEF); nine knowledge areas (integration, scope, time, cost, quality, human resources, procurement, communication, risk); forty-two processes broken into five process groups (initiating, planning, executing, monitoring and controlling, closing). Then for each of the 42 processes, detailed  inputs, tools & techniques, and outputs are defined.

Might it be possible to simplify all of that to something like this:

  • Four phases and process groups
    • Concept (Discovery)
    • Develop (Plan, Blueprint)
    • Execute (Build, Test, Monitor)
    • Finish (Deploy, Implement)
  • Six knowledge areas
    • Integration
    • Scope
    • Resources (including human resources, procurement, finances, time)
    • Communication
    • Risk
    • Quality
