Is the key to a successful project in the planning, as the axiom goes… or have we already been lost in the trees? My problem with this is that it’s a very narrow, incomplete answer to a much larger scope problem. Creating the project plan is important, but it’s not “the” key to project success — in fact, anyone taking this literally might assume that focusing on the project plan will therefore lead to success. Not so by any stretch. (It also reads like a few introductory sentences lifted from the PMBOK). For my two cents: Project success comes from involving the right project leadership (with measurable, established success under their belts), and establishing and following the right process for the project.
