Workforce, Labor Standards & Skills Planning worked example

Labor Variance with highest efficiency reading observed of 20 value: a worked example in workforce, labor standards & skills planning

What does the result look like when highest efficiency reading observed reaches 20 value? The full calculation is worked below with real intermediate numbers. Use it when labor variance in workforce, labor standards and skills planning is being audited or compared against a control chart.

The inputs for this scenario

  • Highest efficiency reading observed: 20 value (raised for this scenario; the documented default is 8)
  • Lowest efficiency reading observed: 12 value (unchanged)
  • Standard (nominal) efficiency target: 10 value (unchanged)

Working through the calculation

  • Applying the documented formula (Labor variance range = highest labor variance reading - lowest labor variance reading) to the inputs above produces each figure below.
  • At this operating point the engine returns 0 % for labor variance variation, the number this scenario is built around.
  • At this operating point the engine returns 0 value for spread.
  • At this operating point the engine returns 20 value for minimum.
  • At this operating point the engine returns 12 value for maximum.

How this compares with the baseline

  • Against the tool's baseline example, where highest efficiency reading observed sits at 8 value and the headline result is 40 %, this scenario comes in 100% below the baseline at 0 %.
  • A figure at this level is achievable when highest efficiency reading observed is genuinely sustained, not just peaked for a shift. Range-based variance is sensitive to a single outlier; one bad reading can dominate the spread, so pair it with a look at the full distribution before drawing conclusions.

Results at a glance

  • Labor variance variation: 0 % (headline result)
  • Spread: 0 value
  • Minimum: 20 value
  • Maximum: 12 value
