It’s difficult to manage all of it, but it’s impossible to ignore it.

It can help business owners understand how their business functionsand how it serves their customers. It can help companies reveal new opportunities, dig up unknown problemsand even make more money. It is an asset to any company that takes the time to position it in the right way,but it’s up to each company to take the initiative to do so. The first step is to consider big data within thecontext of the customer. What kind of interaction does the customer have with the company and how can thoseindividual touch points be used to paint a complete picture? Then, the business needs to figure out creativeways to use that information.         Data assets might look different in each industry, but the real value of the data lies not in its type but inwhether it can help you increase your value or retain customers. According to Jeff Tanner, professor ofmarketing at Baylor University, the information you get from your customers empowers you to deliver bettervalue over time and create more opportunities for your business. While it may be possible to assign a cashvalue to big data, those numbers aren’t likely to make it onto the balance sheet. The data’s real value is revealedwhen it’s positioned in the context of the following three questions: 1) How will it make the business morepredictable? 2) How will it help replicate success for the future? 3) How will it enhance customer engagement?
