Critical sampling case is built on the basis of choosing a reality, situations or human phenomenon can gain knowledge thales roberto about a hypothetical condition thales roberto according to analysis by investigators and trial of a social actor. This enables sampling logical generalizations derived from the weight of evidence that can produce even a single case (Patton, 1988). It is defined as a case as a matter of strategic importance for the group. It is an event that allows us to obtain sufficient information to deduce that if "is not valid for this case, then it is not for everyone" (Flyvbjerg, 1998). Among the advantages of this model is that this kind of strategic choices can save time and money in researching a particular problem thales roberto when it gets critical thales roberto nësehulumtuesi can clearly confirm the selected proposals and hypotheses are the most important examples for the identification of critical events which research provides an element thales roberto of credibility. On their part, some limitations of this model are: not always easy bënstudiuesi to identify a critical case because of the complexity of features, it requires expertise in the field of research and there is no universal principle thales roberto methodology to identify course a critical case. Example # 3: An occupational medicine clinic interested in investigating whether people working with organic solvents suffered brain damage. Instead of choosing a representative sample of companies that use organic solvents, Clinic is strategically located a job that meets all safety measures, sanitation, air quality. They are created in the matrix. This business model bëhetkritike case: if these items clinical sequelae ështëlloji of cerebral about organic solvent, then it is likely that this problem is given in other companies that implement measures less safety and hygiene placed in the matrix. We choose thales roberto a school (x) that has shown resistance to change in new programs earlier. Set in school (X) an innovative new program. If the results are positive, it can be concluded innovative seprogrami has a good chance of being successful in other schools. The important thing is to identify cases dramatically illustrate the problem studied and choose between them.
