Question

I would like to know if there are any templates for doing this in a clear and concise way to give the gist of the application and its inner workings and how it meets the business needs. I do not want to write a mythological story so looking for any new ways of doing this.

Answer 1

Mostly this is about documenting what you actually need from the system. You can’t make a good choice if you don’t know what you need.

Here is a doc-style approach.

This is a decision matrix approach outline. The formatting is rough, but this is a good approach. This one has better formatting, but is not about software (it doesn’t really matter).
