Lean Manufacturing & Operations worked example

Labor Productivity Rate with total good units produced of 400 units: a worked example in lean manufacturing & operations

This worked example runs the labor productivity rate numbers for a tougher week than the baseline: total good units produced of 400 units instead of the typical 800 units. Calculate labor productivity by dividing total good output by total direct labor hours to measure workforce effectiveness.

The inputs for this scenario

  • Total good units produced: 400 units (the input this scenario stresses; the baseline uses 800)
  • Total direct labor hours: 40 labor hrs (held at the documented default)
  • Conversion factor: 1 x (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Labor Productivity = Good Units / Direct Labor Hours x Conversion.
  • Labor productivity (units per labor hour) works out to 10 units / labor hr at these inputs, and this is the headline figure for the scenario.
  • Raw ratio works out to 10 value at these inputs.
  • Conversion factor works out to 1 x at these inputs.
  • Total direct labor hours works out to 40 value at these inputs.

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 50% below the baseline at 10 units / labor hr.
  • Use it for shift-over-shift or line-over-line productivity tracking, standard-setting, and gauging the impact of process or staffing changes. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.
