Just like a doctor diagnoses a patient, an analyst performs a diagnostic analysis to find the cause of a trend, pattern, or any condition affecting a particular situation. But of course, unlike the doctor's techniques, it requires techniques such as data mining and correlation analysis to make a diagnosis. And organizations and companies can act more robustly with the data generated by using these techniques.
However, it is necessary to draw a limit to what the diagnosis analysis does. It can be considered as an intersection between descriptive and predictive analysis. It gives a more detailed description of the situation than the descriptive analysis, but it does not go so far as to speculate about these descriptions, like the predictive analysis.
In this article, information about what diagnostic analysis is, when, and how to use it is shared with you, accompanied by examples.
A diagnostic analysis is a type of data analytics used by businesses and organizations to answer the question of why a situation occurred.
The -Why- question here is important because while descriptive analysis investigates -What happened-, the diagnostic analysis examines the factors that caused the situation.
Knowing when to use diagnostic analysis in data analytics is essential for effective results. Businesses aim to take more consistent steps by carrying out data analysis, especially at turning points and before an important activity. It allows valuable information to be brought to light by being used to examine the depths of real-life scenarios. To better understand when to use diagnostic analysis, some specific scenarios of diagnostic analysis are listed below:
Best times to use diagnostics analysis
Using diagnostic analysis in research is an integral part of every business and organization. It is a medium between descriptive analytics and predictive and prescriptive analytics. Knowing this position of diagnostic analysis will help you determine the direction of your analysis and find a solution to your problem more easily. Generally, diagnostic analysis has advantages such as:
Pros of using diagnostics analysis
✅It helps researchers to identify patterns. These patterns are used as clues to get to the root of the problems and help reveal the big picture.
✅It enhances the decision-making process. Businesses can use the analysis as a base to strategize their future steps.
✅It is used to understand historical data effectively. Statistical models can show many data points you may have missed at one point in your research or hypothesis.
✅It is a base for a wide range of analytics. If you want to advance diagnostic analysis, you will reach predictive analysis. If you want to advance predictive analysis, you will reach prescriptive analysis.
Which method you choose for the purpose of your data analysis is important. You can always turn to different methods, come up with a new method yourself, or use many methods together. However, diagnostic analysis techniques that stand out with their effectiveness will be mentioned now:

It can be used to find the source of the problem as a result of the relationship between the independent variable and the dependent variable.
It is a very simple method created by writing reasons in different categories between the fishbones on a fishbone diagram. It is especially used in product design, production, and marketing.

Three diagnostic analysis examples will be shared with you to help you get used to the concept of it:
It is known to everyone that the sales of a business do not always proceed in the same order. Your sales may change due to seasonal factors, competing companies, the emergence of new technologies, and similar reasons.

Thus, you can determine which issue you need to focus on; for example, you may require a better customer representative, which helps you to reduce customer churn.
Companies sometimes encounter a pattern of massive employee turnover. It is essential for you to make a correct diagnosis in order to intervene in this problem correctly.
