Coating QC Release Time at 29% cure, retest, and documentation allowance: a worked example

This worked example runs the coating qc release time numbers for a tougher week than the baseline: 29% cure, retest, and documentation allowance instead of the typical 40%. Estimate coating QC release time from required release checks, lab completion rate, and allowance for cure, retest, and documentation.

The inputs for this scenario

  • Release checks required: 38 checks (held at the documented default)
  • Release checks completed per minute: 0.22 checks / min (held at the documented default)
  • Cure, retest, and documentation allowance: 29 % (the input this scenario stresses; the baseline uses 40)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base coating QC release time = release checks required รท release checks completed per minute.
  • estimated coating QC release time works out to 223 hr at these inputs, and this is the headline figure for the scenario.
  • base coating QC release time works out to 173 hr at these inputs.
  • cure, retest, and documentation allowance works out to 29 % at these inputs.
  • release checks completed per minute works out to 0.22 pieces / min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where cure, retest, and documentation allowance sits at 40% and the headline result is 242 hr, this scenario comes in 7.86% below the baseline at 223 hr.
  • Use it to forecast batch release timing and set realistic ship dates, or to find where QC release time is being lost. 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

  • estimated coating QC release time: 223 hr (headline result)
  • base coating QC release time: 173 hr
  • cure, retest, and documentation allowance: 29 %
  • release checks completed per minute: 0.22 pieces / min
