Misaiming about metrics

In order to protect the guilty, my source for some the silly statements I read about business management will not be revealed. Recently, I read this statement in a book about business metrics.
“Measurement is the connecting fiber that can make all the parts work together [in a business or government enterprise]. Achieving this kind of coordination and alignment is impossible without exceptional performance measurement.”
Let’s consider the metaphor of a multi-movement mechanical watch. You know: the kind of watch that keeps time in minutes and seconds, tells you the day of the week, the day of the month, and the phases of moon.

Now, without a doubt, a huge number of measurements were made, formulas developed, and calculations made about the sizes of the gears, the number of teeth in each gear, their placement in relationship to one another and more. A watch is all about measurement. A watch’s whole purpose “measurement.” It only exists “to measure.”

Nevertheless, it is not the accuracy of the measurements that make the watch fulfill its functions properly. When you get right down to it, it is not even the accuracy of the calculations that went into the design of hundreds of moving parts. It is not the accuracy of its manufacture that—at the root—cause the timepiece to function as a “system” and do precisely what is expected of it.

It isn’t any of those things—at the root!

What, then, is at the root of a “system” that functions smoothly, efficiently and effectively? At the root of that highly effective watch’s ability to function is something entirely distinct from “measurement.”

What is that mysterious thing that all too frequently escapes the business intelligence fanatics? What lies at the very core, but is often overlooked by the “metrics maniacs”? What seems to conceal itself from those who seem to be convinced that if management could just get enough “information”—enough metrics—they could manage flawlessly?

The answer is—as W. Edwards Deming told us years ago—“theory.”

The people who designed all of the components of the multi-movement “watch” that does what it does so smoothly, efficiently and effectively had a “theory” about watchmaking long before they ever drew the first plans or began fabricating the first gear.

The business metrics book from which I got the quote at the opening of this article contained a diagram similar to that above. But this diagram is wrong in lots of ways. But, really, only two are critical.

Here’s what the diagram ought to look like:

The foundation of making a business that works—and stays working—is theory. And, more importantly, if the only “goal” of your “measurements” and “management” is a bunch of departments surrounded by a compensation system, then your business probably won’t last too long—except by “luck.”

The “goal” of your “system” should be—indeed, must be—profit. And, as W. Edwards Deming put it so well, “Information tells you nothing without theory.” Theory is the context by which information is interpreted and made the basis for action to change the outcomes.
