In the chapter, we stated that “there are countless possible measures of process performance, many of which are derived from the four core measures” quality, cost, time, and flexibility. In the following table, identify how you think the three measures we described (productivity, efficiency, and cycle time) relate to the four core measures. Specifically:

• If you think the measure always has a positive impact on a core measure, mark the square with a “+”.

• If you think the measure always has a negative impact, mark the square with “-”.

• If you think the measure can have either a positive or a negative impact, depending on the circumstances, mark the square with “+/-”.

Be ready to justify your answers. What are the implications for using performance measures to evaluate processes?
