Safety & Workforce worked example

Staffing Requirement with total labor hours required for the workload of 160 hr: a worked example

This worked example runs the staffing requirement numbers for a tougher week than the baseline: total labor hours required for the workload of 160 hr instead of the typical 320 hr. Calculate the staffing requirement for Safety & Workforce from the work hours required and available hours per person.

The inputs for this scenario

  • Total labor hours required for the workload: 160 hr (the input this scenario stresses; the baseline uses 320)
  • Available productive hours per operator: 40 hr (held at the documented default)
  • Shift or coverage normalization factor: 1 x (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Staffing requirement = total labor hours required ÷ available hours per person × normalization factor.
  • People required works out to 4 people at these inputs, and this is the headline figure for the scenario.
  • Raw ratio works out to 4 value at these inputs.
  • Conversion factor works out to 1 x at these inputs.
  • Denominator works out to 40 value at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where total labor hours required for the workload sits at 320 hr and the headline result is 8 people, this scenario comes in 50% below the baseline at 4 people.
  • Use it when you have a workload estimate in labor hours and need to translate it into how many people to schedule for a shift, week, or project. 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

  • People required: 4 people (headline result)
