An example of variation are those times when we have output well above or well below our means.
A well-defined process (and it’s coordinated metrics) will accomplish two things for us in times of variation;
- Illustrate the variations as they occur above and below the means in our process.
- Illustrate for us when variances accumulate and should be cause for interaction.
The key point in Business Process Variance monitoring is the understanding that variance does not always equal intervention into the process.
