Many years ago (I won’t tell you how many), my high school computer science teacher first introduced me to the concept of GIGO. It stands for Garbage In, Garbage Out and what it means is your results are entirely dependent on the quality of your beginnings. If you put faulty information into a computer program, you’ll get faulty results coming out the other end, no matter how sweetly designed the program itself is.
The same holds true for business information systems.
If the data you’re putting in to the system is less than high quality, you definitely won’t be getting high quality insights at the other end.
Often times you will see the business intelligence community getting all starry-eyed over the idea of real-time analytics. The idea that a sales person in Vancouver can close a major deal in the morning and you’ll know how it affected sales, inventory, and your bottom line before the ink is dry on the customer’s signature is an enticing one… but is it entirely practical?
Yes, if you are 100% positive that the data being input into your BI system is absolutely, perfectly, squeaky-clean high fidelity data. But if it isn’t, you just might be better off slowing things down a little.
Spending time getting your data model right, building reports, and developing the most elegantly insightful dashboards anyone has ever seen won’t mean a thing if you don’t also spend time making sure the data being generated by your business processes is of the very highest quality. And if for some reason you’re forced to work with suboptimal data, you should also be spending time making sure you understand how that data is contaminating your system and how you can adjust your systems to clean out the garbage and start giving you quality results.
You can use one of these four ways to address the problem.
All of this falls under the larger heading of “data governance” and as we talked about last week, we believe data governance is going to be more and more in the news this year when it comes to business intelligence. As more and more businesses embrace BI, there is going to have to be a corresponding increase in awareness of the importance of good data governance, too.
