The critical case samples are built on the basis of the choice nbc news of a situation, phenomenon or human reality understanding of a perceived state under analysis by the investigator and trial of a social actor. This example sets logical generalization derived nbc news from the weight of evidence that may even produce a single event (Patton, 1988). It is defined as a case with an issue of strategic importance to the group. This is a matter that allows us to derive enough information nbc news that if 'is not valid for this case, then it's not for everyone "(Flyvbjerg, nbc news 1998) to acquire. Among the advantages nbc news of this model is that this kind of strategic choices can save time and money in research on a particular problem when it is critical if the researcher clearly confirms the statements and hypotheses are selected examples important for the identification of critical events that offer research an element nbc news of reliability. For their part, some limitations of this model are: not always nbc news easy to make the researcher to identify a critical nbc news case because of the complexity of the functions, it requires expertise in the field of research and there is no universal methodological principle nbc news certainly nbc news A identify critical case. Example # 3: A professional medicine clinic interested in investigating whether people with organic solvents suffered brain damage. Instead of choosing a representative sample of the companies that make use of organic solvents, the clinic strategically located a workplace nbc news that meets all the safety measures, sanitation, air quality. Those who are established in the matrix. This business model is the critical case: whether the clinical facilities are the type of cerebral effects associated with organic solvents, it is likely that this problem is given based in other companies that see less security measures and hygiene in the matrix. We choose a school (X) that showed resistance to change in the last innovative programs. Set to the school (X) an innovative new program. If results are positive, it can be concluded that the innovative program has a good chance of being successful in other schools. The most important thing is to identify cases dramatically illustrate study the problem and to choose between them.
