A case study lets you conduct an in-depth study in a particular subject as an investigation into an individual circumstance. This study may be conducted by a single person, group of person, or a business. There are benefits of the case study for both the readers and the researcher. However, pitfalls can be problematic for the researcher to establish facts from opinions and statistics. This section details out the Advantages and Disadvantages of the Case Study.
The process of conducting a case study involves collecting in-depth data about the individual entity or using several collection methods and tools. There can be offline, online or even both types of resources involved during the case study. Access to refined knowledge is one of the greatest advantages of the case study.
Case studies offer various verifiable data from direct or indirect observations of the individual entity that can be further embedded into crisp information that concludes with derivatives. The observed information is simply based on the input-output method using which the results about other identical entities can be easily drawn.
All the data collected and observed during the study is real-time. Most of it is also based on researchers’ opinions as the same can depend on data-driven results such as positive or negative impacts. For example, to aware others about the pros and cons of solar energy, the researchers have to find the facts in support and against it through real-life examples.
Case studies were first conducted in Medical sciences where chosen subjects were to go under experiment-based observation. These studies were relevant to every participant and the observers, including the parties for whom these results were produced. Thus, the case study method essentially forces people to decide the question being studied and then defend their position through facts.
Whether hand-written notes, online reviews, historical data, or real-time experimental tasks, every material has great significance in conducting case studies. Most case study methods involve more than just one source of information, such as interviews and direct observation. Case histories from a records database and Questionnaires can be used with this method. Writing notes in diaries and journals about the entity is a good example of a regular case study based on day-to-day observations.
Case studies can also be a very cost-efficient way to research a remote area. Researchers don’t have to move from places to places or facility to use the available case study method. Research can be done and concluded through phone, email, or messenger services. Discussions can take place entirely over the conferencing app such as zoom or Skype. That means the case study method is good for exploratory and formative research, even if it must be managed remotely.
Started with the medical Sciences Case Study Method has now expanded to every sector considering the consumer market's dynamic structure. These case studies are important to examine key results, the positive or negative outcomes of particular services and product that's either launched already or is ready to be out. A case study method, however, is not always as productive or efficient. There can be disadvantages of case study, which needs to be considered even before researchers dive into it.
The case study method is based on fact-based data mostly. It’s the researcher or the data collector who specifies the data and defines its values. Deciding what’s factual and what’s not can be difficult when entered records are false or real-time information is not available. If the data is based on opinions, there will be an error in the concluding report and stats.
Time is the one of the concerning disadvantages of Case Studies next to data redundancy. From the start till the end, the procedure of conducting case studies extensive is time-consuming. The more researchers involve in it, the more complicated it becomes. There is an enormous amount of data that's compiled. It's not just the researchers who can affect the outcome in this type of research method. Participants can also influence the conclusion by giving inaccurate or incomplete answers to questions. This means there will be more consumption throughout the research. The best solution to this problem is to break the process of case studies into smaller modules and assign each researcher's responsibility strictly.
Provided there are no efficient data, participants, or researchers' involvement, the case study method can be useless and a waste of money. Case study methods require the participation of the individuals or entities involved for it to be successful. The skills of the researcher help determine the quality of information being received from different sources. Unskilled or inexperienced researchers can make this research method useless and inefficient. If researchers are uncertain of handling this process, insufficient data will do the rest of the damage.
Rather than covering an entire group or community, it’s better to focus on a single entity and draw conclusions based on the feedback and characteristics. The case study method requires a small sample size to yield an effective amount of data to be analyzed. If there are different demographics involved with the entity or different needs that must be examined, then the case study method becomes very inefficient.
This can be considered like integration and differentiation methods in mathematics. Studying a small unit yields the same results as studying the entire system. Collecting information for a large group or system can be full of errors, ambiguity, and inaccuracy.
Moving from door-to-door or visiting the participants in different locations is a tiresome activity that can be more intensive as the data piles up. The case study method requires researchers to have a high level of language skills to collect data successfully. Researchers must be personally involved with the participants in every aspect of data collection. From reviewing files or entries to conducting personal interviews, the concepts and themes of this process rely heavily on the amount of work each researcher is willing to put into the real world.
These advantages and disadvantages of the case study are a useful way to evaluate this research method's effectiveness. Overcoming the negatives and honing the researcher's skills can help derive factual and accurate data on whether research is short or long.
It converts client opinions into useable information. It transforms speculation into reality. It is essential for all concerned parties. It makes use of a variety of research methods. It may be done remotely and from anywhere in the world. It's cheap to run and straightforward to access to readers.
Observation bias exists in the information on exposure. They are susceptible to selection bias. They are inefficient for uncommon events. They do not allow the calculation of incidence (absolute risk).
The advantages of survey research include its cost-effectiveness, generalizability, dependability, and versatility. Survey research has several flaws.
The elements contributing to the case study's difficulty can be quickly determined by performing a deep strength and vulnerability analysis. The critical difficulties for case studies are generalization, validity, reliability, theory role, authority, authenticity, dependency, and longevity.
