5. 5 How to Use Fit Tables You have to use the Fit tables to understand better the requirements. In the Fit tables you cannot find directly the answers to the target question but you can use them to verify if your hypotheses (how to compute a value, what is the correct workflow, what are the constraints, etc …) on the Requirements are correct.
