Cold Chain & Temperature-Controlled Operations worked example

Excursion Investigation Workload at 25% qa escalation and documentation allowance: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop qa escalation and documentation allowance to 25%, then walk the calculation through step by step. Estimate QA and operations labor hours needed to investigate temperature excursions.

The inputs for this scenario

  • Excursion records, lots, or shipments to investigate: 18 investigations (held at the documented default)
  • Excursion investigations completed per hour: 2.5 investigations / hr (held at the documented default)
  • QA escalation and documentation allowance: 25 % (the input this scenario stresses; the baseline uses 35)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base excursion investigation workload = excursion records, lots, or shipments to investigate รท excursion investigations completed per hour.
  • estimated excursion investigation workload works out to 9 hr at these inputs, and this is the headline figure for the scenario.
  • base excursion investigation workload works out to 7.2 hr at these inputs.
  • QA escalation and documentation allowance works out to 25 % at these inputs.
  • excursion investigations completed per hour works out to 2.5 investigations / hr at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where qa escalation and documentation allowance sits at 35% and the headline result is 9.72 hr, this scenario comes in 7.41% below the baseline at 9 hr.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to qa escalation and documentation allowance, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It assumes a single average rate; a batch with several complex multi-lot escalations will take longer than the flat allowance predicts, so review the mix for outliers.

Results at a glance

  • estimated excursion investigation workload: 9 hr (headline result)
  • base excursion investigation workload: 7.2 hr
  • QA escalation and documentation allowance: 25 %
  • excursion investigations completed per hour: 2.5 investigations / hr
