ARIS – process modeling tool
dr Tomasz Ordysiński
Modeling in ARIS
ARIS (Architecture of Integrated Information System) is a concept, method and tool to design and model new processes or improve existing ones.
First time introduced by prof. Sheer in 1991 as CASE tool to support computer IS implementation.
Second step – focus on process.
Aspects of ARIS:
Concept of ARIS (1) – general idea of process modeling,
Concept of ARIS (2) – set of methods to model data, functions, organization and processes,
Concept of ARIS (3) – as a base of ARIS-Toolset software
ARIS – House of Business Engineering – complex concept of process management
Why process modeling before IS application?
The process analysis/modeling shows exact data flows, requirements so the final application is perfectly fitted to organization.
Complex IT solutions require a lot of work done by several people – they must operate with the same term, data definition and general view to user’s needs.
Application lifecycle according to ARIS
In ARIS concept we can distinguish 5 phases of IS lifecycle (following picture)
On steps 2,3 and 4 there are used 3 basic description levels according to process analysis.
ARIS - views
Data View - What information is important? (ie.: Customer, Supplier, Product, Material Calculation)
Function View - Which functions will be performed? (ie.: Production Plan Creation, Order Processing)
Organization View - Which organizational units exist? (ie.: Purchasing, Sales, Accounts)
Process View - The relationship between data,functions and organizational units
Product/Service View - Which products/services are important? (ie.: checked order, customer,invoice)
ARIS model – typical example: customer order processing (interaction diagram)
