What is the ideal purpose of big data in today’s business environment? This is a question Ratna Chinnam has been exploring for more than a quarter century now. Dr. Chinnam is one of the world’s foremost experts in Big Data & Business Analytics. He’s a Professor in the Industrial & Systems Engineering Department at Wayne State University and has authored over 150 publications covering the domains of business analytics, supply chain management, freight logistics, operations management, sustainability, healthcare, and smart and connected systems.

How would you define “business analytics”?

Analytics can be defined as the application of machine learning methods, statistical methods, optimization methods to drive business success. They tell us how to improve customer service. How to improve supply chain management. How to improve product development. How to improve manufacturing. And many other things.

Much of the business community does what we call descriptive analytics. So, most companies tend to have historical data. And then they can develop dashboards around, the status quo.

The other name for this is called business intelligence platforms, or BI dashboards. Most of these BI platforms, or descriptive analytics platforms, only look at historical data. An informed entrepreneur or business manager has to digest that information and look to the future more confidently. Predictive analytics is about projecting historical patterns into the future.

The final step would be prescriptive analytics. This deals with what kind of actions we must take based on the predictive analytics. So, the decisions that the firm has to take, both strategic and tactical decisions, as well as operational decisions to maximize revenue or maximize profitability.

What do you feel are the top reasons why businesses hesitate or maybe do not know where to start when it comes to integrating big data analytics into their decision making?

Irrespective of the industry, I have yet to meet a company that has really excelled in leveraging the wealth of data that they have. There are several reasons for this. Most companies have historically developed IT platforms in isolation. They are not really designed to facilitate easy exchange of information with each other. If you really don’t have the data at your fingertips, you’re not able to be nimble.

The second point would be culture. Historically there was not much recognition within leadership as well as senior managers regarding the power of analytics and data-informed decision making. They have not really been trained on the importance of information technology and how it can be leveraged to drive business success.

And then there are a number of other challenges, as well. For example, the company might have a presence on Facebook, or on LinkedIn. And then they are trying to just mine that data to do things like sentiment analysis. But that’s not where the opportunity is. Whether it be a small business or a medium-sized business, every business has priorities, pain points, and that’s where we ought to be starting. So, for example, if a small business is struggling with production quality, they should be thinking about the data that informs their production process and where optimisation possibilities lie.

How did you get started with your centre and how does it involve the business community?

Six years ago, we founded the Big Data & Business Analytics Group at Wayne State University. Dr. Satyendra Rana, myself, and some of our business school colleagues, we established the Group with these annual symposia on Big Data & Business Analytics. The event has grown quite a bit. We recently had our fifth event, and we had 500 people participate from banks, hospitals, defence contractors automotive companies, and more. We also bring in the leading vendors in that space.

The approach that we have taken is a case study centric. It’s not academics trying to talk to the business community. Instead, it’s business speaking to business about what’s working, what’s not working, their personal experiences, where did they get started, how they are improving.
