Requirement analysis for a processing system for energy supply contracts

The first step is to analyse the old application, which is implemented using VBA. In parallel, customer workshops are held to identify the actual current requirements for the system. UML diagrams for the representation of use cases and BPMN diagrams for processes provide graphic support in the documentation of the results. Within the scope of these analysis activities, the definition of the target processes as well as the underlying requirements is carried out according to the MoSCoW principle. The result serves as the basis for carrying out a make-or-buy analysis.
