Lean Manufacturing & Operations worked example

Labor Productivity Rate with total good units produced of 2,000 units: a worked example in lean manufacturing & operations

Push total good units produced up to 2,000 units and the picture changes. This example computes every intermediate figure at that operating point. Use this calculator to measure and compare labor productivity across shifts, lines, cells, or time periods. Productivity improvement is a core lean metric for continuous improvement.

The inputs for this scenario

  • Total good units produced: 2,000 units (raised for this scenario; the documented default is 800)
  • Total direct labor hours: 40 labor hrs (unchanged)
  • Conversion factor: 1 x (unchanged)

Working through the calculation

  • Applying the documented formula (Labor Productivity = Good Units / Direct Labor Hours x Conversion) to the inputs above produces each figure below.
  • At this operating point the engine returns 50 units / labor hr for labor productivity (units per labor hour), the number this scenario is built around.
  • At this operating point the engine returns 50 value for raw ratio.
  • At this operating point the engine returns 1 x for conversion factor.
  • At this operating point the engine returns 40 value for total direct labor hours.

How this compares with the baseline

  • Against the tool's baseline example, where total good units produced sits at 800 units and the headline result is 20 units / labor hr, this scenario comes in 150% above the baseline at 50 units / labor hr.
  • It computes good units produced per direct labor hour, optionally scaled by a conversion factor to express output in a different unit. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Labor productivity (units per labor hour): 50 units / labor hr (headline result)
  • Raw ratio: 50 value
  • Conversion factor: 1 x
  • Total direct labor hours: 40 value
