Space Payload & Avionics Manufacturing worked example

Documentation Hours with documentation hours severity score of 3 score: a worked example in space payload & avionics manufacturing

Here is what the math looks like when conditions slip. We hold every other input steady and drop documentation hours severity score to 3 score, then walk the calculation through step by step. Estimate documentation hours for space payload and avionics manufacturing using production-ready inputs so teams can rank risks and decide which issue needs containment, controls, or escalation first.

The inputs for this scenario

  • Documentation hours severity score: 3 score (the input this scenario stresses; the baseline uses 6)
  • Documentation hours occurrence score: 4 score (held at the documented default)
  • Documentation hours detection score: 3 score (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Documentation hours risk score = documentation hours severity score × documentation hours occurrence score × documentation hours detection score.
  • Documentation hours risk score works out to 3.35 score at these inputs, and this is the headline figure for the scenario.
  • Documentation hours severity score works out to 3 score at these inputs.
  • Documentation hours occurrence score works out to 4 score at these inputs.
  • Documentation hours detection score works out to 3 score at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where documentation hours severity score sits at 6 score and the headline result is 4.55 score, this scenario comes in 26.37% below the baseline at 3.35 score.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to documentation hours severity score, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. Like any RPN, it can mask a high-severity risk behind low occurrence and detection; always review severity on its own before dismissing a low composite score.

Results at a glance

  • Documentation hours risk score: 3.35 score (headline result)
