What is a case study and how to write it?

My name is Heiley Durst and I am a professional writer. I want to write here about such type of academic assignment as a case study - the scholarly work which is the most difficult for each student according to the requests left at my service. Firstly I want to speak over the definition of such academic work, so a case study involves a thorough, in-depth and detailed study of a specific case or cases in a real-world context. For example, case studies in medicine may focus on an individual patient or disease; business case studies can cover the strategy of a specific firm or a broader market; similarly, case studies in politics can range from a narrow range of events over time (eg, a specific political campaign) to a very modest enterprise (eg, world war).
