I came to a successful project with 4 years old, it is already in the production. The problem is that, the project is not documented anymore, it depends on 2 senior developers only, they know the system, they test, they handle change of requests..
I need to know what is the best practice, or what are the main steps that I have to do in order to document all the modules starting from high level design through component analysis & design, code comments, till the configuration management.
The traditional project management processes don't give me a clear idea of how to take the control back of a an old project.
Thanks.
