Measurable

Name	Measurable
Statement	Performance achievements should be measured against the standards, as well as customer satisfaction with the service provided. The performance measures used should be comparable over time and tracked to demonstrate improvements; standards should be written in terms of specific measures that will be used to appraise performance.
Rationale	Standards, especially those intended to improve or affect performance, should be objective, measurable, realistic, and stated clearly in writing (or otherwise recorded).
Implications	Not all standards will have a measurable component. However, we should strive to determine if and where standards can be measured. The following questions may help determine specific measures. For each measure, ask: How could [quality, quantity, timeliness, and/or cost effectiveness] be measured? Is there some number or percent that could be tracked?
