A case study in project management is a systematic analysis of the successes and failures, costs, benefits and risks associated with a particular project. It provides an opportunity to review the process, identify where things went wrong, and assess how similar problems can be avoided in the future. By examining all aspects of a project, case studies provide valuable insight into the project management process, enabling businesses to make informed decisions that will help lead to better outcomes. Case studies are an essential tool for any business looking to maximize their success rate on projects.
