  3. 3. Agenda The Use of Case Studies The Web Advice Module The (dis)advantage of a real-life Case Study Now it’s up to you18-10-2012 © NESMA 2012; IWSM 2012 3
  4. 4. Why not read the manuals
  5. 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 domain18-10-2012 © NESMA 2012; IWSM 2012 5
  6. 6. COSMIC documentation structure Working group experience:18-10-2012 © NESMA 2012; IWSM 2012 6
  7. 7. Selecting a real-life application to become a Case Study
  8. 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 guidelines18-10-2012 © NESMA 2012; IWSM 2012 8
  9. 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 applications18-10-2012 © NESMA 2012; IWSM 2012 9

  11. 11. Describing the complete measurement process
  12. 12. Practical example material  Reduce 19 pages of functional design to 6 pages  Avoid reference to organisation specific technical jargon  Remove ambiguities18-10-2012 © NESMA 2012; IWSM 2012 12
  13. 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 clear18-10-2012 © NESMA 2012; IWSM 2012 13
  14. 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 interaction18-10-2012 © NESMA 2012; IWSM 2012 14
  15. 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 complicated18-10-2012 © NESMA 2012; IWSM 2012 15
  16. 16. Finalizing this Case Study
  17. 17. Version 0.8  Written and reviewed by 15 practitioners from 5 different countries  Most of the issues now cleared18-10-2012 © NESMA 2012; IWSM 2012 17
  18. 18. It’s up to YOU to finalize it  Download the 0.8 version from COSMICON.com  Send your comments to wgcosmic@nesma.nl  January 2013 the final version will be published18-10-2012 © NESMA 2012; IWSM 2012 18
