The process of analyzing gage variability is often highly structured, involving an examination of the gages themselves for sensitivity to temperature changes, magnetic fields, and other factors. These are the easy ones. The second area of variability has its source in gage operators themselves, who may have different levels of training, experience, fatigue, and even attitude.
Collecting data offers clues to sources of variability. But when this disciplined analysis fails to uncover real reasons for variability, it may be time for the Sherlock Holmes of variability to look at operational definitions—often the most overlooked consideration when evaluating variation among measurement devices.
Elementary, my dear Watson? Perhaps, but nonetheless these definitions can lead to levels of variation in gage output if they are vague or nonexistent. “In the opinion of many people in industry, there is nothing more important for transaction of business than use of operational definitions. It could also be said that no requirement of industry is so much neglected” (Deming, 276).

If you get off the highway and take an alternate route when traffic slows to one lane, you are making a prediction. Likewise, if you decide to invite someone to dinner, that too is a prediction. The scientific method? Predictive in nature. Every time you make a decision, you are making a prediction of an outcome, and choosing one over another based on this prediction.
Prediction skills become second nature because of this daily application. These predictions may not be based on data or evidence, but involve some subjective guess about a preferred outcome. In the case of choosing a traffic route or a dinner date, it’s clear that not much data is involved. The decision involves subjective interpretations, intuitive hunches, and guesses about potential outcomes.
Will data analysis really enhance prediction accuracy? There are no guarantees, without adding a certain amount of understanding of data, of variation, and of process performance.
“A hot dog at the ball park is better than steak at the Ritz.”
At least that’s what Humphrey Bogart is said to have commented. With the summer season underway and ball parks in full swing, hot dogs at the ball park, on the grill, and in the lunchbox will help to celebrate National Hot Dog Month in July. And many agree that there’s nothing like a hot dog with mustard. Or relish or ketchup or smeared with chili.
