A non-technical approach to justifying an estimate:
“The minute when I start justifying my estimate or explaining why I have to change a lot of things, I’ve lost. [...] So I have found that the way out of this situation IS NOT to go technical and start explaining how code works. They’re NEVER going to say gee, now that you gave me a quick tutorial in web application design, and then you explained how you’ll need to rewrite the permissions decorators to use a new state factory, I guess your estimate makes sense.
Instead, this approach works OK for me:
Me: I think it is a great idea and it won’t require a lot of research and development, but it’s going to take a while. So based on that estimate, should we put into the queue or not?”
