In every developers life there is one series of questions that are hard and sometimes plane impossible to answer.
Questions as:
These are not an easy questions and there are not easy answers.
So normally when you try to explain that you can't give exact estimate and time-plan for everything you just get the "Puzzle look" and normally asked "Why?"
Well browsing around the internet i stumble on a very good analogy that explain "Why?" is so hard and mostly wrong every time.
Questions as:
When will it be ready ?
How much time it will take ?

I assume you know how to put together a jigsaw puzzle, for nearly any 3 year old can put together the most basic ones.
So let me ask you a question. If I went out and bought 5 jigsaw puzzles, each with say 2,500 interlocking pieces, how long would it take you to put together anyone of them?
Can you tell me within 25% of the actual time how long it will take you? After all, you DO know how to put together a puzzle, right? And it you can do that, can you tell me what day you'll have all 5 of them finished?
I want to know! And can you have your reply ready for me by 3pm today?
