Case studies have been regarded as a design, as a qualitative methodology, as a particular data collection procedure, and as a research strategy. But every survey which was conducted in a certain organization just using questionnaire could not be considered as a case study. Research which is regarded as case study, should be very clear about methodology. So, in this paper after reviewing method and steps of an appropriate case study, an illustrative case study which aims to investigative effectiveness indexes in one of the nongovernmental organization in Iran (Urmia child foundation) has been discussed. At the end, it is proposed that given case studies’ unclear status, researchers need to be very clear about their interpretation of the case study and the purpose of carrying out the study. They also should address the questions with regard to design, data collection procedures and analysis; and avoid common misunderstandings about case-study research.
