If you cannot measure it, you cannot manage it. Can we all agree on that as a starting point? It’s a management cliche, I know, but it’s also a truism. If you cannot measure the output of a process, then trying to drive process productivity is like trying to direct the swings of twelve stick-wielding, blindfolded first graders as they attempt to whack a candy-filled pinata in a lightless supply closet. You’ll only end up with a lot of wasted effort, some crying, half the team begging for some light and the other half groping for the door. And no damn candy, to boot.
When it comes to quality management, certain outputs are easily measured. How many defects did you count? What were the results of your measurements? How accurate is your measuring system? Is the operation successfully reducing the number of defects in the process? The only quality metric that ultimately matters, however, goes unmeasured in all but a minority of organizations, leaving the quality function marginalized and swinging at pinatas in the dark.
If your organization is serious about improving the quality of its product or service, then you likely already know the metric I’m referring to. If your organization isn’t serious about this kind of improvement, then you’re likely gearing up to be indignant or queuing your favorite “why quality can’t be measured” argument. If that’s you, then do me a favor and hold your thought as if it were chicken salad and you are Jack Nicholson’s waitress in the Five Easy Pieces cafe scene.
The only quality metric that ultimately matters, is, of course, impact on organizational expenses, or EBITDA. Any organization can measure the impact of their quality function in dollars, and do it specifically in a controlled manner validated by the Controller. Most simply chose not to go that route. Doing so is like flipping on the lights in the supply closet. Most executives are smart enough to know what that closet will look like after being trashed by a dozen blindfolded first graders armed with bats, and would rather focus on other problems. The problem with willfully blind organizations, though, is… well, that they’re willfully blind.
They are also less than informed as to the specific nature of their improvement opportunities. Implementing Quality Cost Principles can shed all kinds of light on the nature of organizational waste. Here’s one simple approach that can be modified to fit just about any cost accounting system:
- Classify all expenses as either quality costs or non-quality costs (an expense is a quality cost if it relates to organizational defects in any way).
- Break quality costs into three main categories: internal defects, pre-distribution external defects (after production but before use), and external defects (those defects discovered by the customer).
- Sub-categorize quality costs as design costs, prevention costs, appraisal costs, control costs, or improvement costs. Training expenses, for example, can be categorized as prevention costs focusing on the reduction of internal defects. Expenses relating to re-work can be categorized as appraisal costs (identifying re-work) or improvement costs (performing re-work) associated with pre-distribution external defects. You can come up with your own approach and definitions – the point is to have a classification system and consistently apply it.
- Provide an accounting code to each quality cost as it passes through finance.
- Develop monthly reporting processes summarizing quality costs as a percentage of total costs.
- Incorporate the resulting quality cost data into monthly scorecard reviews.
- Utilize quality cost data to drive improvement by reducing the ratio of defect-related expense dollars to total expenses that your organization spends in a given month, and by moving quality cost dollars from control and appraisal buckets to design, prevention and improvement buckets.
Hey, I said it was simple. I didn’t say it would be easy.
