We all like to have data to support our decisions. But we tend to look at this myopically – a decision needs to be made, and we simply need some data to justify it. True, almost everyone, from retail companies to agricultural manufacturers, strives to make data-backed decisions, but what is the right way to use data to make better, more accurate decisions?
It begins with understanding what type of data you need for a particular decision. If you need to find the cause of a problem or predict what will happen in a specific part of your business, the type of data you choose is essential to success.
For instance, when you want to see what trends occurred in your business in the last quarter and find the data-backed explanation for them, descriptive and diagnostic data will come in handy. But in case you want to build a strategy or even shape the future of your business, predictive and prescriptive analytics will be much more applicable.
Here are the four types of data and how they can help you make better decisions:
Descriptive Data
Descriptive data answers the “what happened” question. Think of an e-commerce store owner who wants to know what products were the least popular in California during the Christmas season. Descriptive data identifies information on what items people were least willing to buy in that period. It provides a historical view of past performance and is typically easy to capture.
Diagnostic Data
While descriptive data shows us what happened, the diagnostic data answers the question of why it happened by seeking a cause-and-effect relationship. With diagnostic data, you can quickly identify patterns and how different factors relate to each other. For instance, marketing departments can use diagnostic data to define why some campaigns were more effective than others.
Predictive Data
Predictive data uses historical or current data to forecast potential outcomes. For most companies, this is where the “magic” happens. Predictive data is more complex than descriptive and diagnostic data, and it always requires data scientists’ expertise. For example, Vodaphone decided to offer special deals on plans and roaming to the clients who were most likely to go skiing. To define those clients, Vodafone’s analysts built a predictive model trained on the data of the people who had been using their phones at major ski resorts throughout Europe in the past.
Prescriptive Data
Prescriptive data is based on predictive data but supplements its outcomes with recommendations for the future. In other words, this type of analytics answers the question “How to make something happen?” providing decision-makers with the optimal action plan. For instance, airline companies can constantly adjust ticket prices depending on ever-changing factors like weather conditions, fuel prices, and customer demand.
Every type of data is intertwined with the others in the analysis cycle. The latter gives businesses answers to questions like what happened, why it happened, what could happen next, and how to make something happen. By using descriptive and diagnostic data, you can clearly identify what brought you to your current state. Meanwhile, predictive or prescriptive data will provide you with a clear vision of future perspectives. All these types of data have their function – it’s up to you to understand the decision you’re trying to make, and what you need to make it.
