Knowledge management, evaluate to create effective change in the quantity and quality of manufacturer agents and organs of society and deals. The factors are human resources and financial, material, technology. This evolution to more efficient is the goal of science is done. Founder of experimental science because the origins of matter claimed in the beginning, like other management science, the laws are universal. But gradually there human phenomena known that the claim is not based and were inevitably raised induction theories. This change in paradigm change in management science that defined science simultaneously before World War was caused in management science research methods, initially with the aim of further defining the principles is also undergoing transformation. Taylor's father founded following the principles of management science to: 1. Development of science for replace science with old empirical methods that used by workers, 2. Cause goals to achieve the highest paid wages and lack of access to the most goals will cause a decrease income, 3. Selecting science workers and their continued growth, educating all workers for obtaining higher rank or level workers in their jobs, 4. Concurrent use of scientific knowledge and selection of workers to work to achieve the best results, 5. Share the work and responsibilities between workers and management and necessary interaction and close cooperation between them, Gradually engineering methods provide principles that were followed instead of the research methods that were more sociological and psychological approaches were. This approach, generally have been based on survey. The rule these methods continued until 1990, but in recent years, theorists went to modernist (post modern) methods of philosophical hermeneutics. Case study was as on of the educational method in first and then as a research method (case research) helps to manage the development of science.Gradually engineering methods provide principles that were followed instead of the research methods that were more sociological and psychological approaches were. This approach, generally have been based on survey. The rule these methods continued until 1990, but in recent years, theorists went to modernist (post modern) methods of philosophical hermeneutics. Case study was as on of the educational method in first and then as a research method (case research) helps to manage the development of science.Knowledge management as the scientific facts can make explored the organizational and human phenomena that are interacting was been neglect. So it had to use of induction approaches. The other hand, due to the portrayal of the future role of organizational factors such as technology, structure and financial resources and the other hand, being unpredictable human behavior as core organizational issues can not be self-sufficient of deduction theorists.in this paper is Case study (case research) as the research method, its position in process of management theorists and the role of knowledge management is to be determined.
