How to respond when you are asked for an estimate?
The problem with estimates is mostly requirement analysis.<p>When people say they need feature A, B and C and ask when I will have it done, I split it up in tasks that take below a day, estimate these tasks and add 50% for safety.<p>This works in most cases.<p>But often the reason why projects won&#x27;t finish on time is, because people don&#x27;t know what they want.<p>They ask for A, B, C, you estimate it right or probably too pessimistic and get done ahead of time, but still the project is late in the end because they forgot about D, E, F, G, H and J. In the end you can fit D, E and maybe F in the time you have left because you got A, B, C done quicker than estimated but G, H and J are still missing.
