Hear about how ATP do the Business Modeling, how we decide what is going to be handled by an IT-system, how we specify the System Use Case representing that. On the information side, how we do Information Concept modeling with the business, how we specify the Services and service operations to fit a SOA Architecture. How we integrate functionality and information in the Description of the Use Cases, where we describe what the Actors do, what the system does, and which Service operations make it happen. Hear about the benefits and challenges of using a modeling tool to integrate and keep track of all the models.
