In Harvard case study method, it is being emphasized that cases are to be analysed and decisions have to be taken by the students based on the facts presented in the case. No doubt it implied that decisions are taken using the theories of business (successful conduct of the business). What is unique about the case study method is that students have to apply multiple theories to the facts given in the case and come out with a decision. Then they have to present their decision to other students in the class and get their concurrence for the decision taken. This exercise of presenting the decision and making efforts to convince them with the facts of the case and the analysis and synthesis made to arrive the at decision will improve people interaction skills that includes communication skills.
Hence, as part of business administration course business analysis has to be done to take decisions to solve various business problems or to take advantage of various business opportunities.
Now, we have International Institute of Business Analysis offering courses and certification in business analysis.
