Actor modeling

In computer science, Actor modeling is a form of software modeling which focuses on software actors. Actor modeling is most prominently used for the early modeling of requirements; through this it becomes possible to understand who the users and stakeholders of a system are and what their interests and needs are regarding that system. The increasing complexity of today's systems makes it more appropriate to take this approach, instead of a traditional, more mechanically focused approach. When thinking along the dimensions of users and their needs, it is easier to comprehend what the system is designed to accomplish. This approach furthermore helps the users to define the requirements for the system. The approach of actor modeling is normally combined with the modeling of goals and tasks to give a better understanding of the situation the user is in. There are different modeling languages that support actor modeling; examples include i* and EEML.
