The ARIS concept (Architecture of Integrated Information Systems) by August-Wilhelm Scheer aims to ensure that an enterprise information system can completely meet its requirements.

This framework is based on a division of the model into description views and levels, which allows a description of the individual elements through specially designed methods, without having to include the entire model. The methodology serves as a systems development life cycle for mapping and optimizing business processes. These processes are mapped for each description view, starting with the business management question up to the implementation on data processing level.

ARIS relies mainly on its own five-view architecture (ARIS house). These five views are based on function, organization, data, product or service views of a process, and the process view itself, that integrates the other views. The classification is made to break down the complexity of the model into five facets and thus make business process modeling simpler.

Each view of the ARIS concept represents the model of a business process under a specific aspect:

Each description view of the ARIS house is divided into three description levels:

Concept

Structured representation of the business processes by means of description models that are understandable for the business side (depending on the view, e.g.: ERM, EPC, organization chart, function tree)

Data Concept (= data processing concept, IT concept)
