Because there is a different focus in service ops in order to add value, the
wastes come in different forms.

Characteristics of Good Measures
Personal Impact – The causes that affect the outputs are under the control of the people or team who are responsible.
Immediacy – There is little time between changes in the inputs and changes in measured performance.
Characteristics of Good Measures
Proximity – The measure is closer to the performance of the process.
Causality – Measure assesses a cause rather than an effect.
Proportionality – Changes in the measure are proportional to changes in performance.
Characteristics of Good Measures
Customer Focus – Measure reflects performance relative to customer requirements.
