Process Modeling Software Process Evolution Process Modeling Approaches Process Modeling Architectures

Process Modeling and Process-based Quality Approaches Structure of Process-based Quality

Approaches Comparison of QAP elements vs. process

elements

Software lifecycle models (eg. waterfall model -idealised processes)

Methodologies (eg. JSP, JSD - recipes, paperwork)

Formal development (proving correctness, not scalable)

Automation (Software Development Environments – eg. requirements

specification cannot be automated) Management and Improvement

(ISO, CMMI - increased bureaucracy) Process Modeling and Process Programming

(Osterweil, Little JIL)

• Companies are using multiple quality approaches simultaneously (eg. ISO 9001, CMMI, ITIL etc.)

• Hundreds of documentation pages are present at organizational level, even more at org & project level

• No one wants to read and process it

for the problems faced

1) 6 QAPs were analysed2) Similar elements are present in the QAPs and

processes3) Could serve a basis for a common QAP meta-model.

In order to create a meta-model for process-descriptive quality approaches requires further steps:

analysing the structure and content further well-known quality approaches and methods;

selecting the possible main elements to be used for the meta-model;

analysing process modelling languages, models and methods.

examining information loss during transformations.
