FUNCTIONAL FACETS OF DATA ANALYTICS

Welcome to the vibrant world of data analytics! Picture it like this: If data were a painting, then analytics would be the varied brush strokes that bring the artwork to life. And just as an artist has different techniques, we’ve got four main categories to make sense of all this data: Descriptive, Diagnostic, Predictive, and Prescriptive Analytics.

First up, Descriptive Analytics is the snapshot of your data here and now. It’s like your Instagram feed but for your business, showcasing current trends, outliers, and various shades of your operational performance.

Then comes Diagnostic Analytics, which is essentially the backstory to your snapshot. Ever wondered why your profits are soaring or tanking? Diagnostic Analytics is your go-to. It helps answer questions like, “Why did we get a sudden traffic spike on our website?” or “What’s causing the slowdown in our digital systems?” In fact, diagnostic analytics is so insightful that it’s helping companies understand not just what happened, but why it happened.

Next in line, Predictive Analytics is your friendly neighbourhood fortune-teller. While it won’t tell you how to win the lottery, it will use mathematical models to forecast what might happen in your business landscape. So, you’ll have an idea of potential future scenarios, whether it’s consumer demand or market trends.

Finally, we have Prescriptive Analytics, which is like your personal GPS for business decision-making. It won’t just tell you that a storm is coming; it will suggest the best route to avoid it. For example, if a car model is in high demand, prescriptive analytics can craft a unique strategy to boost sales in different regions, taking into account local culture, weather, and even language.

Here’s where the numbers really kick in. As of now, a whopping 97.2% of companies are putting their money into big data and AI projects. That investment seems to pay off too, as these companies see an average profit increase of 8%. While the global big data market is rocketing past the $56 billion mark, the average company is only analyzing 37-40% of its data. As for AI, 35% of companies are already on board, and 42% are gearing up to join the revolution. When it comes to customer insights, 80% of companies rely on customer satisfaction scores, and social media is becoming a data goldmine for 23% of businesses.

DESCRIPTIVE ANALYTICS

Welcome to the world of Descriptive Analytics, where history isn’t just something in dusty old books; it’s a treasure trove of insights waiting to be discovered. Descriptive Analytics is the process of interpreting historical data to understand changes in business operations. Think of it as a tool that takes all that raw data and turns it into something managers, investors, and stakeholders can not only understand but use to make important decisions.
