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)

Summarization

ARIS vs. other architectures of process

modeling

The unique feature of ARIS is integration of:

architecture

modeling methods

IT modeling tool

Other concepts usually focus on one of those aspects.

The most known are:

CIMOSA (Computer Integrated Manufacturing Open System

Architecture)

IFIP – ISM (Information System Methodology)

ISA (Information System Architecture)

Case study

Small advertising agency in Szczecin produces calendars, mugs,

paper and other gadgets with customer logo or according to any

specific order.

During a year there is a strong trend that 80% of annual income is

generated from October till December (mainly calendars)

The number of customers and orders is very high than and all the

production order „queue” is kept in production director head. Last

year he got sick and production was stopped – company lost a lot of

customers and money.

When new customer appears there is prepared unique project for

him (graphical) and send to him for approval in printed form. There

number of project which were done for nothing is high. Customer

sends back the answer/improvements or just rejection.

What do you think should be reorganized and how?
