If you take a book dealing with requirements management, you will usually be told how to do requirements management in a simple project starting from the scratch.
What you will not find that often is a description of how to behave if you join a project which is already ongoing and which already faces some challenges. The goal of this blog post is to give you some ideas of what can be done to deal with requirements in flawed projects.
What I would like to do is to describe the settings and challenges that our team encountered during a real project. My goal is to give you an impression of which concrete steps we have taken in order to improve the situation and how well the improvement measures worked within the project setting.
