In my experience, it's more or less 2 parallel processes which are very alike. If I really had to guess as to time, it's be something like: Plan -> Code -> Refactor -> Replan -> Code -> Refactor 10% -> 15% -> 30% -> 20% -> 10% -> 15% For me, the first refactor and replan phases take the longest time.
