Lesson 4
Business Process Modelling
LO
1. You can explain the purpose of modelling and understand its importance.
2. You can explain the five descriptive views for the architecture of integrated
information systems (ARIS), as well as name and illustrate the respective
three levels of abstraction of these views.
3. You can name the difference between process and business process.
4. You know the difference between business model and process model.
5. You can name characteristics of mature and immature organizations with
regard to processes.
6. You can identify different maturity levels based on the Capability Maturity
Model.
7. You know the BPMN method of process modelling and its advantages.
8. You can create flowcharts based on verbal descriptions of simple processes
using the BPMN.

1. Purpose and Importance of Modelling
Model
• a representation of something
• a commonly agreed abstraction, which describes and represents the
relevant aspects of a “system under study”.
• accurate enough to reflect the features of the system being modeled, but
simple enough to avoid confusion
• needed when the reality is too complex to be fully understood
• used to abstract a part of reality so it can be understood by a human or a
machine
• used to understand a subject of interest in order to make a decision
Purpose
The purpose of the model determines the abstraction level. -> The degree of
detail you see is linked to address a specific problem.
Descriptive model
• analysis and documentation of existing (actual) situation
• analysis of problems
• explaining objects, structures, and procedures or processes
• preservation of implicit knowledge (e.g., procedural knowledge that is only in
people's heads)
Prescriptive model
• decision basis for new (target) state
• developing design hypotheses
• solution variants to problems
• facilitates communication in the company during the implementation
o between management, specialist departments, and IT department
o between project teams
