Plans are nothing…
…planning is everything. (Eisenhower)
Oh the times I have seen hours, days, weeks spent writing detailed documents/ Gannts/PowerPoints to explain the 10 minutes of genius agreed at the outset. That 10 minutes of genius starts to dissolve the further you get away from the planning session, so, simple plans, quickly distributed. Pen and paper, a photo of a whiteboard, a hastily written email…. that’s fine. That’s where the value is.
If someone wants a week’s worth of documentation, ask them why, until you get an answer that makes sense. They probably don’t trust you to get the job done and the best way to dispel that belief is to prove them wrong with a fantastic end result. Plans are procrastination – don’t hide behind them.
