The project team involved at the Williams Specialty Company has completed their work on the logical data flow diagrams for the as-is system. The set of data flow diagrams has been checked for basic syntax errors, and thanks to the work of the newest team member (see supplemental minicase 1), has also been checked for balance. At this point, several of the more junior project team members assumed that the models were complete, and that the team would quickly move into the development of the process model for the to-be system. However, you know that in order to assure that the model is as correct as possible, it still needs to be checked for semantics errors. Describe what is meant by semantics error in a process model. Describe several techniques that can be used by the team to check the data flow diagrams for their semantics quality.
