Don't Feed the Thought Leaders
Something I like to do when given “non-contingent advice” about a project, is to ask the person making the suggestion to review the published current requirements (functional and non-functional) and constraints, and submit a recommended change.In decades of projects, I have yet to receive one.When receiving offhand hedgehog like suggestions from someone important, e.g. the CEO, I tend to ask if they insist we pause and consider it, given that to do so would likely affect the cost and progress of the project.In decades of projects, I have never been asked to do so.
