Structure diagram

This model type contains the object of type structural element and the connection type contains. Since a structural element can be assigned to all model types, this model has a wide range of uses. It is often used as a starting model for various views of a company.

Process landscape

A process landscape is used to structure the process portfolio of a company. Processes in a process landscape can be connected in a sequence to describe an end-to-end scenario or a value chain. Processes can be arranged hierarchically to further refine specific process areas. The process portfolio is usually structured into the following three process types:

1. Management processes (e.g. strategy)
2. Core processes (i.e. value-adding processes)
3. Support processes (e.g. marketing)

Event-driven process chain (EPC)

The event-driven process chain (EPC) is a set of related tasks or activities performed to produce a product or service. The EPC consists of events that trigger activities, while rules control the flow of the process. The EPC describes:

• Which activities are performed in the course of a process.
• Which organizational units participate in process execution (persons or groups of persons).
• What input and output data are used.
• What IT systems are involved.
• Which events and risks occur during process execution.

Connectors are used to split and join the control flow. Split connectors have one incoming and several outgoing connections; join connectors are the reverse.

BPMN process

BPMN (Business Process Model and Notation) is used to model both business and workflow processes. It is an open standard for process modeling maintained by the Object Management Group (OMG).

The BPMN collaboration diagram is used to model the interactions between participants, e.g., in a business-to-business (B2B) context. Participants are involved in the process and are represented by pools. Interactions between these pools are represented by message flows (message exchanges).

These elements represent organizational units. Using pools or embedded lanes, tasks can be assigned to individuals or groups of people.

System landscape

A system landscape describes which IT systems belong to which logical units or domains. This assignment information is relevant for budgeting and for defining administrative responsibilities.

Data model

A data model represents the data view of a company, e.g. showing which business objects exist and how they relate. The entity-relationship notation is used for data modeling. Data models are created, e.g., to define database structures. The cardinalities of relationships between entities illustrate the number of interconnections.

Organizational charts

Organizations and companies illustrate their structures with organizational charts. Using ARIS symbols (organizational unit, role, and person), relationships between individual units like departments or employees are clearly visualized. The relationships show:

1. Who is responsible for whom?
2. Who is the supervisor or subordinate?
3. How are the communication channels structured?
