[Mikhail_Edoshin]

I write things down and it helps, esp. when I manage to keep it minimally structured: write down a question, then write an answer, split different topics.

Generally I think it is a question of method. If I was to produce a physical thing I would know the steps. One of steps would be a drawing in a known form, with known ways to indicate what is important. With software there is no such a standard form.
