A good case is more than just a description.
Projects we are actualy developing.
It is information arranged in such a way that the reader is put in the very same position as the case writer was at the beginning when he or she was faced with a new situation and asked to figure out what was going to happen.
A Description, on the other hand, arranges all the information, comes to conclusions, tells the reader everything, and the reader really doesn't have to work very hard.
A case study should be defined as a research strategy, an empirical inquiry that investigates a phenomenon within its real-life context.
Case study research means single and multiple case studies, can include quantitative evidence, relies on multiple sources of evidence and benefits from the prior development of theoretical propositions.
Case studies should not be confused with qualitative research and they can be based on any mix of quantitative and qualitative evidence.
The case study is a research approach, situated between concrete data taking techniques and methodologic paradigms.
"Case studies, Analyses of Strategies, Events, Decisions, Promotions, Projects, Institutions, or other systems that are studied holistically by one or more methods. The case that is the subject of the inquiry will be an instance of a class of phenomena that provides an analytical frame — an Object — within which the study is conducted and which the case illuminates and explicates."
