The (dis)advantage of a real-life Case Study
Now it’s up to you

The use of Case StudiesWhy not read the manuals
5
The use of Case StudiesPurpose 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

Working group experience:
The Web Advice ModuleSelecting 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

The disadvantage of areal-life Case StudyDescribing 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 © 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
18-10-2012 © NESMA 2012; IWSM 2012
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 © 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
