GMP Documentation Burden Score with documentation impact severity of 4 score: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop documentation impact severity to 4 score, then walk the calculation through step by step. Score the burden created by batch records, equipment logs, chain-of-custody records, and GMP review requirements.

The inputs for this scenario

  • Documentation impact severity: 4 score (the input this scenario stresses; the baseline uses 8)
  • Documentation workload frequency: 7 score (held at the documented default)
  • Documentation issue detectability: 6 score (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Documentation burden score = impact severity × 0.40 + workload frequency × 0.35 + issue detectability × 0.25.
  • Documentation burden score works out to 5.55 score at these inputs, and this is the headline figure for the scenario.
  • Documentation impact severity works out to 4 score at these inputs.
  • Documentation workload frequency works out to 7 score at these inputs.
  • Documentation issue detectability works out to 6 score at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where documentation impact severity sits at 8 score and the headline result is 7.15 score, this scenario comes in 22.38% below the baseline at 5.55 score.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to documentation impact severity, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. Scores are only as good as the scoring discipline behind them; without anchored rating definitions, two reviewers can score the same batch record differently, so calibrate the scale before comparing across teams.
