I'm sure that the team does not adhere to your approach. Problems should be foreseen in advance. You can solve them gradually, there are no questions, but you need to have a good vision for the development of the project so that some surprises do not destroy or even slow down the implementation of the project.
It is impossible to calculate everything in advance with absolute accuracy. There is always the possibility of force majeure. And those problems that are obvious are already known and spelled out in white paper.
