The term case study is a term that we often interact with in most of our day-to-day activities. So, what is a case study? A case study is defined as an in-depth study of either an individual, a group, or an event. During a case study analysis, the element being analyzed is scrutinized to the core in terms of its life, behavior, and history. Through this in-depth scrutiny, we can identify the aspects such as patterns that might be generalized by others which might be useful in other elements related to the intended case study. It is important to note that case studies can vary from a vast majority of fields including medicine, anthropology, social work, psychology, and politics but mostly it is used in the healthcare industry. It is also important to note that even though a case study analysis intends to learn as much as possible about a subject, most tend to be very subjective which should not be the case.

In this article, we are going to deep dive into the world of case studies to try and identify all the details on how to write a persuasive case study in addition to a summary of some of the pros and cons, types, and examples.

Each case study comes with its benefits and limitations that are widely used by researchers to identify if the intended case study is worth undertaking or analyzing and appropriate to their individual needs. The gained insights from a selected case study can be useful to other researchers to develop additional ideas in addition to questions to be explored in the future.

So, let us identify some of the pros and cons that might come with a case study. Remember, these pros and cons do not fit into every case study.


  • Researchers can establish a hypothesis that can later be used in experimental research

  • Enables the researcher to collect as much information regarding a case that can be used for investigation

  • It turns client observation into meaningful data in addition to turning opinions into facts

  • It uses several different research methodologies

  • Enables a researcher to have an opportunity to investigate an unusual or rare case study


  • Analysis of a case study can take quite a long to complete(Gaille, 2018)

  • The analysis can be influenced by biases from the researcher as one uses his or her own words

  • It cannot necessarily be generalized to the larger population

  • Aspects such as cause and effect cannot be demonstrated well

  • It requires a small sample size to be effective

  • The case study draft may not tell the entire story

Note: During the process of choosing a case study, a researcher might be interested to explore a recent phenomenon or a unique case study to try and tell a story such as compelling story such as a customer story. Additionally, it is vital to note that gathered insights from a case study cannot be used to establish a cause-and-effect relationship between variables.

There are various subgroups within the broader category of case study, each of which is specifically selected for usage based on the investigator's aims and/or objectives. The following are examples of case studies:

Illustrative case studies

This is a case study that uses one or two scenarios of an event to establish how a situation might be and it is usually descriptive.

Collective case studies

This type of case involves conducting a study of a group of individuals in a community or a certain setting.

Descriptive case studies

This case study involves initiating a descriptive theory that follows up with an observation of the subjects which is later compared to another existing theory.

Exploratory case studies

Before undertaking a large investigation, researchers are usually advised to conduct an exploratory case study. This case study assists to identify queries and selection types of measurements that can be used before the main investigation(Clearinghouse, 2022).

Explanatory case studies

These are frequently employed in causal analysis. In other words, scientists are interested in examining elements that could be to blame for specific events.

Intrinsic case studies

This case study evolves around a researcher who has a personal interest in a case such as observation and analysis of siblings or a family.

Instrumental case studies

These happen when a person or group makes it possible for researchers to comprehend more than what is initially clear to onlookers.

NOTE: From the list above only three are commonly widely used by researchers. These are instrumental, collective, and intrinsic.
