The tool I’m doing needs to balance best practices and simplicity. I can include a lot of features that helps to do better estimations but the key issue is the simplicity.
The consequence, I’m automatizing all that I want.
Some parts are more simple than I want but I need to do it so automatic in order do it easy.
The usability is also important, I need to do it so intuitive and providing easy steps for the estimation.
The most difficult issue is going to convince some people about the benefits of the tool; we need to do a good job in the communications and awareness.
