To build deeper understanding using case studies, it's important to understand the usefulness and drawbacks of cases.Domains like business and product management aren’t structured domains, which is why case studies are a powerful way to study them.Case studies enable understanding of the context of different problems and how people solved them.Applying wrong analogies can be a drawback of using case studies, as they can lead to an ineffective solution.Good case studies include user knowledge, industry knowledge, product path, and internal context.Long-form articles are often good case studies, provided they cover all the required aspects.The reliability of the source is also an important factor to consider while looking for good case studies.Counter-factual evidence to challenge the narrative can also affect the quality of a case study.Case studies written by founders and operators, such as those used by Harvard Business School, are often more effective.Social media posts and news articles can often be sources of narrative bias when dealing with case studies.
