Download "How to Develop Sound Measures"
Rummler-Brache's Process Improvement Certification Workshop shows managers how to redesign cross-functional processes so employees can achieve stronger results with less effort. This makes success less dependent on a few overachievers, who, by the way, are more likely to stick around when senseless barriers are removed from their work.

How to Develop Sound Measures
By Geary Rummler and Alan Brache
Performance—that is, output—should be measured at all three levels (Organization, Process, Job/Performer).
Follow this sequence when developing your metrics at the different levels:
- Identify the most significant outputs of the organization, process, or job. ...
- Identify the critical dimensions of performance for each of these outputs. Critical dimensions of quality include accuracy, ease of use, novelty, reliability, ease of repair, and appearance. Critical dimensions of productivity include quantity, rate, and timeliness. Critical dimensions of cost include labor, materials, and overhead.
- Derive critical dimensions from the needs of the internal and external customers who receive the outputs and from the financial needs of the business.
- Develop the measures for each critical dimension. For example, if “ease of use” has been identified as a critical dimension of quality for a given output, one or more measures should answer this question: “What indicators will tell us if our customers find our product or service (output) easy to use?”
- Define goals, or standards, for each measure. A goal is a specific level of performance expectation. For example, if a measure for ease of use is “number of customer questions/complaints regarding product use,” a goal may be “no more than two questions/complaints per month.” As continuous improvement efforts bear fruit, goals should become more ambitious.
The following table shows several examples of measures developed in this way
|Insurance claims qualified||Accuracy||
|Timeliness||Average loss notice processing/confirmation time||15 minutes per loss notice|
|Orders taken||Accuracy||Number accurate orders/total||100%|
|Timeliness||Number of minutes||Within 2 minutes|
Important characteristics of this method to developing measures are:
- They are output-driven. This is in contrast to the frequent practice of settling on goals and measures because they are topical or easy to measure rather than because they will help achieve a critical output.
- They are customer-focused: the outputs, critical dimensions, and goals are all determined to a substantial degree by customer requirements.
- They reflect the reality that most outputs have several critical dimensions and that measures must be multidimensional in many cases. We can no longer get away with thinking that “we can have quality or we can have quantity, but we can’t have both.” We can have both, as well as timeliness. That is the new customer requirement.
