Design docs for existing functionality
Has anyone attempted to write design docs for existing code/component?
Well, we have lots of C/C++ code with us and we have been asked to write design documents for the applications.
Writing a design doc for existing code ought to be much easier than writing a design doc before coding. For one thing, you don't have to make any decisions. You just have to describe what the system is already doing. The only potential problem that I can see is if you've got old code and nobody remembers what it does.
We are totally new to the code. There is no one to help us on this.
Maybe you'd like to reverse-engineer a picture of the code, using some tool like http://www.scitools.com/ucpp.html or another.
Um, good luck.
