Are you still estimating work to be done? Still struggling to figure out is it time or complexity estimation? Which one is better? If complexity, what to do with simple but long lasting tasks? What is a 3? What is an 8? What is complexity anyway?
At XING, in all of the teams I have been working with, we have found an answer on all of the questions above that satisfies us and the stakeholders. We have stopped doing estimation on the small scale.
