Disclaimer: I did not come up with this approach. I am sure that I read about 10/50/99 about 10 years ago. I remember this well, but I can’t find the proof in Google. Besides me wrote about this one or two times.
Super obvious and super important: the only feedback you can give at the 10% stage is 10% feedback. You should not give 10% feedback at the final 99% stage. And vice versa: you cannot give 99% feedback at 10%.
Take notes. Write down the decisions that came to your mind at this point. You will regret later if you do not. You will need them in the future if you decide to change something.
