I don't know I am posting this question. in the right place. I thought I could post it on stackoverflow but this places looks more suitable for this question.
I am wondering that how much drawing a a blueprint/sketch of the architecture of a project before starting to actually build it would help? could it be useful? what are your experiences on this. I am about to dive into a big project on my firm and I just wanna explore the options before getting into it.
Also, is there some online tools which are specifically designed for that kind of purposes so that I can do this kind of stuff on my machine instead of on a paper.
