What is case study

Case studies express the detailed information on the account of different companies, industrial sectors, people involved and the projects. Case study is actually a detailed illustration of a particular incident/accident in any industry or company. The case includes all the relevant and vital information including decision making which is related to the case. Case study analysis has become one of the popular form of assessment in the universities throughout the world. The primary reason of this giving so much importance to case study analysis is, case study is a detailed description to the real time problem that has been faced. Once the students analyze these problems they gain great analytical understanding and problem solving skills. Case studies developed for business schools may range from two pages up to thirty pages and even more, depending upon the nature of the case and the academic level. Students may be asked to analyze large number of case studies as part of their academic assessment. These studies are basically conducted to examine what measures have been taken by other business professionals to tackle with some specific issues and challenges (Karen Schweitzer, About.com Guide).
