A case study critically assesses an event, a place, personality, or situation to draw a conclusion. It uses all background information to identify the key problems and recommend further action. 
The case study approach allows in-depth, multi-faceted explorations of complex issues in their real-life settings. 
For example, case studies in healthcare may focus on an individual patient or ailment.
