I have been included in a very big project, with surprisingly, unorganized - to none - documents.
Every meeting, we had been asking for documents back and forth and they can't provide one. There's no Business Requirement Document, No Functional Requirement Documents, no use cases. All they can come up is a 'matrix' - which is also vague - and screen mockups. Then when they deliver something, the documents were not really updated on our shared folders and we are surprised about the changes. We do have change request process apparently they didn't comply with the rules and making it look like they just delivered this for the sake of hey we have done our jobs do yours.. I badly wanted to just clean up everything and make myself feel comfortable to test it but due to no idea or no clue on which parts of the function - or even rules of each one of it - what can I do to improve the quality of the project process?
I am tempted to at least maybe document the functional document or business requirement for them. Is there any thing that I could consider before jumping into this crazy world of documentation?
