Step 0 is necessary before any initiative. Large or small, complex or simple.
If the first step is in the wrong direction, all the effort and of course the end result will be wrong. Then it’s time for Step x+1, which is called rationalization.
Simply put: typically the concept itself is wrong.
This means that
the expectations for the outcome are wrong,
planning is wrong
expectations must be changed or adjusted continuously without any foundation
plans must be adjusted continuously to meet wrong and changing expectations
nobody knows exactly what they are doing (even if they pretend to do so)
systems and team dynamics decline
morale and motivation drops
teams fall apart
after finishing the initiative, rationalization starts, to explain why what everybody knows is not good, is actually the only possible good outcome
