We use Sharepoint at my company to store all documentation but it seems disorganized to me so I'm wondering about better ways to organize it.  We build business software systems, so we have documentation for products (the systems that we sell) as well as projects (changes to the systems).  The requirements documents for our projects are all listed in one central place in Sharepoint, in alphabetical order.  We don't seem to maintain a "master" set of requirements documents at a product level, so if you want to know when a particular feature was implemented, you have to search through all of the project workspaces.

For the products I'm responsible for, I think I would like to have a workspace that contains all documents related to the product in chronological order; so the original product requirements and also all of the project documents.   I am also toying with the idea of starting and maintaining a master set of product requirements, which would be all of the project requirements combined into one document.  Is this biting off way more than I can chew?

Does anyone here work in a similar environment, and if so how do you keep things organized so that it's easier to track changes to the product over a long period of time?  The goal is to be able to look back and see when and why (x) feature was done, without having to explore the entire Sharepoint library.
