Business systems and production management systems are designed to support people’s productive activities. The PReP model is a business process modeling method, but to be precise, it is a method for modeling people’s productive activities. In order to design machines that support human activities, such as IT systems, it is necessary to model them.  The model of the designed human activity becomes the definition of the requirements for the machine.  However, many business process models describe “specifications". The PReP model is a way to abstract and define human activities.  What the PReP model considers important is not the definition of notations, but the way in which the concept of human activity is defined, and the way in which the activity process is modeled.  And as a result, The PReP model allows for traceability between human activities and machine specifications.
