Introduction
Business processes are often the starting
point for software development
Business processes define requirements for
the software systems to be designed

Contribution of the Evaluation
Metamodel provides a foundation for an
evaluation
Stresses strengths and limitations of BPMLs Comparison between the BPMLs illustrates the
differences and the similarities
Evaluation can be easily extended with further
BPMLs
Facilitation of finding the right BPML for a certain
purpose

Definition about Business Processes
Definition: "A business process is a group of tasks
that together create a result of value to a customer." [Hammer, 96]
Definition: "Its purpose is to offer each customer the
right product or service, e.g., the right deliverable, with a high degree of performance measured against cost, longevity, service and quality." [Jacobson, 95]

SLIDE 13
Goals of the Extension
Process goals and performance measures are
available in process definitions
13
Variabilities Languages Goals
Current BPMLs do not provide explicit notation
elements for process goals and their measures
E.g. designer has no possibility to integrate time limits
Time Quality Costs
Extending the metamodel of UML 2 AD business process goals and performance measures
SLIDE 14
Contribution of the Extension
Modelling of goals and performance measures
allow
to structure process design, to evaluate the process design, and to evaluate the operating process.
The extended UML 2 AD makes the evaluation
criteria for a business process conceptually visible

Introduction into Variability Models
Variability models define the variability of a product
line
It shows the different variation points and variants of a
software product line.
20
Variabilities Languages Goals
Variability models can be used during the different life
cycle stages of software product lines
Variability modelling is a domain specific modelling
technique
Continual integration into traditional software engineering.
SLIDE 21
21
Motivation
Variability models are not integrated into an
modelling framework like the Unified Modeling Language (UML).
Variability models have also an impact on processes.
Variabilities can change the process flow, e.g.
in a car engine manufacturing process the decision if
the variability manufacture a diesel engine or a petrol engine is chosen, changes the process flow. Variabilities Languages Goals
SLIDE 22

Goals
- 2. Show the dependency between variability
models and Activity Diagrams to make the relationship between structural models and behavioural models visible
- 1. Provide variability models to software developers
as a UML 2 profile

Contribution
The UML profile for variability mode ... can be easily created, presented and edited
with existing UML modelling tools.
... represents variability requirements to software
developers or process engineers in a well-known modelling languages.
... and its shown dependencies onto activity diagrams
visualizes the relationship between structural and behavioural models. The UML profile for variability models ...

Dependency between Variability Models and Business Processes
Variability models show the different variabilities of a
software.
Activity Diagrams are a part of the behavioural set of
UML 2 diagrams
show the control and data flow between different tasks.
The two modelling techniques describe the
complementary views
variability model describes the structural view and the activity
diagram the behavioural view.
