Workforce, Labor Standards & Skills Planning worked example
Takt Staffing at 61% line efficiency: a worked example
This worked example runs the takt staffing numbers for a tougher week than the baseline: 61% line efficiency instead of the typical 85%. Size the crew for a Workforce, Labor Standards & Skills Planning line: the operators needed to deliver all manual work content within takt.
The inputs for this scenario
- Total manual work content: 1,200 sec / unit (held at the documented default)
- Takt time: 180 sec / unit (held at the documented default)
- Line efficiency: 61 % (the input this scenario stresses; the baseline uses 85)
Working through the calculation
- The calculation starts from the formula this tool documents: Theoretical operators = manual work content รท takt time.
- Required operators works out to 11 operators at these inputs, and this is the headline figure for the scenario.
- Theoretical operators works out to 10.93 operators at these inputs.
- Work content works out to 1,200 sec / unit at these inputs.
- Takt time works out to 180 sec / unit at these inputs.
How this compares with the baseline
- Against the tool's baseline example, where line efficiency sits at 85% and the headline result is 8 operators, this scenario comes in 37.5% above the baseline at 11 operators.
- Use it when designing or rebalancing an assembly line, planning a model-mix changeover, or building the direct-labor budget for a new program. 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.
Results at a glance
- Required operators: 11 operators (headline result)
