Formalism, technique and rigour in Use Case Modelling

 
Despite the ubiquity of use case modelling as a concept, there are very many ways to approach it as a practical activity. One key to success on a project is to make concrete and public decisions on many aspects of structure, technique and method. We have indicated here some of the questions that must be surfaced, and a corresponding framework of ideas and practical answers that have worked well. The answers on other projects may differ, but asking and answering the questions is essential.
