4. Why not read the manuals

5. The use of Case Studies
Purpose of a Case Study
 Present practical example material
 Both for novice and experienced measurers
 Describe the details of the measurement process
For the understanding and propagation of the COSMIC method it is
important
 To have Case Studies available
 From all domains of applicability of the method.
The current situation
 Five Case Studies are available
 Most come from the real-time domain

7. Selecting a real-life application to become a Case Study

8. The profile
 Small enough to be measured in half a day
 Simple enough to be understood by novice measurers
 Enough complexity for discussion
 Recognizable real-life functionality
 Covering multiple guidelines

9. The Web Advice Module
 Small business application of a large commercial bank
 A generated advice based on a simple questionnaire
 Using SOA services to interact with other applications

11. Describing the complete measurement process

12. Practical example material
 Reduce 19 pages of functional design to 6 pages
 Avoid reference to organisation specific technical jargon
 Remove ambiguities
18-10-2012 12© NESMA 2012; IWSM 2012

13. For novice and experienced users
 Write down the full measurement process in plain language
 References to the measurement manual and guidelines
 Describe all possible discussions briefly but clear

14. Advantages of real-life specs
 Software everyone can relate to rather than a theoretical case
 Good preparation for real measurement work
 Showing the issues of interaction
18-10-2012 14© NESMA 2012; IWSM 2012

15. Disadvantages of real-life specs
 Describing the process takes twice as many pages as the specs
 A lot of discussion about translating specs to functional user requirements
 Hard to make them unambiguous
 The real world is so complicated
