Business Before Metrics


Don’t let the pursuit of metrics hurt your basic business model. It is imperative to remember that metrics in and of themselves should supplement and enhance business decisions, but not necessarily be the end all and be all of your business. On this Memorial Day, I can think of no better example than that of…

Greater Purpose


I’ve talked repeatedly about planning ahead and the importance of having a perfect data transfer for your data to tell the complete truth. Here is a real life example of this philosophy in action. Several months ago, I stumbled across this video about a new tradition at the University of Iowa’s home football games. Take a moment to…

Thinking Inside the Box


When I was 19, I attended a leadership school where one of the sessions focused on trying to sell an otherwise undesirable product. In the workshop, we were given the opportunity to try and come up with reasons to purchase a bucket of excrement. Many of the people concentrated on the practical uses for poop….

Who Does the Best Imitation of You?


I was fortunate enough to grow up in an era when the likes of Rich Little and Dana Carvey could be seen on a regular basis doing impressions of famous people on late night TV. It was always amazing to me how spot on these gentlemen could imitate the facial expressions, mannerisms, and speech patterns…

What’s in a Name (Calculation)?

Don’t Know Much About… NULL Values


The Best of Sam Cooke was the first CD I ever bought. One of my favorite songs on that CD, “Wonderful World“, begins with the iconic line “Don’t know much about history.” Through the rest of the song, Cooke sings about a number of the other things he “don’t know much about”. He then ends…

Be the Frank Lloyd Wright of Your Data Warehouse


I studied architecture in middle school (yes, I am that big of a nerd) and fell in love with the patterns of Frank Lloyd Wright designs. Widely regarded as one of the best architects in U.S. history, Wright’s designs are legendary for their attention to the smallest of details. He drew the plans, selected the…

The Truth, the Whole Truth, and Nothing but the Truth…


How you finish that statement tells a great deal about a person. If you finish with “so help me God”, then you’re likely either a Christian, or spend way too much time watching courtroom dramas. I’m kidding – we all know there’s no such thing as too much Matlock or Perry Mason. Alternatively, if you’re…

Regression to the Mean Machine


Old habits die hard. That, in a nutshell, is the concept behind regression to the mean. To understand this concept, let’s first define what mean, means (and forgive me for sounding like Bill Clinton during the Lewinski affair). Mean is the highfalutin way statisticians say “average”. With regression to the mean, the philosophy is that…
