How do you do it? I mean, how do you know when you reached the necessary granularity? And even if you know, sometimes it just means more questions that the client might not be able to answer at that time. Do you come up with a worst and best case and carry that delta up the breakdown hierarchy of components? Are you able to do this for every kind of task that can come up in a project? (From frontend design to backend implementation and third party system integration and infrastructure setup and then product deployment.)
