4. Research goal
• To provide a solution of sufficient quality for using
multiple quality approaches simultaneously
• Sufficient quality: deals with current problems
− multi-model software process improvement (MSPI)
criteria, defined based on current problems

5. Concept: mapping elements of quality
approaches to process elements
CMMI
• Mapping of quality approach Process area
elements to process Specific goal
elements Specific practice
• Work products, practices, Example work product
roles Subpractice
• Mapping is performed on
instance level Generic goal
Generic practice

of a research developing a common meta-model for process-
based quality approaches and methods,” in Proceedings of
EuroSPI 2008 Doctoral Symposium, Dublin, Ireland, 2008.

6. Process Based Unification (PBU)
framework
1. PBU concept
− mapping quality approaches to a single, unified
process
2. A PBU process
− Operationalization of the concept
3. Unified process
− result of the PBU process

Software Quality Approaches,” in 2009 Fourth IEEE International Conference on Global Software
Engineering, Limerick, Ireland, 2009, pp. 285–288.

13. Quality of results
• Case study results
• Walkthroughs (experts and users)
• PBU framework
• Conformance to MSPI criteria
− Handling differences (unified process)
− Traceability (mapping)
− Adaptability and expandability (mapping, iterative)
− Completeness (100% coverage + user acceptance)
− Appraisal support (mapping)
− Repeatability (documentation)
• Validity and reliability
− Ecological (environment) , internal (logic), construct (thick descriptions
and process), external validity (other settings), reliability (repeatability)
