Line Clearance Workload at 7.2% documentation and verification allowance: a worked example

This worked example runs the line clearance workload numbers for a tougher week than the baseline: 7.2% documentation and verification allowance instead of the typical 10%. Estimate the time a packaging line clearance takes from the number of clearance checks, the rate they are completed, and an allowance for verification.

The inputs for this scenario

  • Line clearance checks: 120 checks (held at the documented default)
  • Check completion rate: 12 checks / min (held at the documented default)
  • Documentation and verification allowance: 7.2 % (the input this scenario stresses; the baseline uses 10)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base line clearance time = line clearance checks รท check completion rate.
  • Planned line clearance time works out to 10.72 hr at these inputs, and this is the headline figure for the scenario.
  • Base line clearance time works out to 10 hr at these inputs.
  • Documentation and verification allowance works out to 7.2 % at these inputs.
  • Check completion rate works out to 12 pieces / min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where documentation and verification allowance sits at 10% and the headline result is 11 hr, this scenario comes in 2.55% below the baseline at 10.72 hr.
  • Use it when scheduling the clearance gate between runs, validating staffing for clearance, or estimating how much non-producing time clearance adds in a high-changeover environment. 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

  • Planned line clearance time: 10.72 hr (headline result)
  • Base line clearance time: 10 hr
  • Documentation and verification allowance: 7.2 %
  • Check completion rate: 12 pieces / min
