Discussions and modelling of business processes and therein manipulated data can be maximum as good as the underlying comprehension of the matter itself.

Based on his experience, the author claims, that lacking or flawed understanding is the main cause for bad software and failed IT-projects. IT people must understand what users need (and not only what they want or ask for!). Business and management people must understand, what information they need to be able do their business, how they use this information and what they have to ask from IT-people to get real help out of software.

In this book a method and procedure is described, how mutual understanding between all stake holders can be accomplished and documented. Furthermore experiences are shared and chances and difficulties of its application are discussed.
