How do you calculate a documentation risk score?

Combine the severity, occurrence, and detection scores on a consistent scale. With severity 6, occurrence 4, and detection 3, this model returns a documentation risk score of 4.55, letting you rank it against other documentation risks.

What is a good documentation risk score?

Lower is better. There is no universal threshold, but items scoring in the upper third of your program's range should get corrective action first. Compare scores only when the same scale is applied across all documentation risks.

What do severity, occurrence, and detection mean for documentation?

Severity is the impact if the record is wrong or missing (e.g. grounding a flight unit); occurrence is how often the gap happens; detection is how likely your review process catches it before delivery. Here they are 6, 4, and 3.

Why does a missing traveler score high on severity?

Because acceptance data packages are contractual on flight programs — an incomplete traveler can block delivery or force a re-inspection regardless of whether the hardware is good. Severity should reflect that flight-readiness impact.

Can a low documentation risk score still be dangerous?

Yes. A rare, easily caught but catastrophic gap can post a low composite while its severity is high. Always screen severity independently rather than relying on the blended score alone.

How is this different from a hardware FMEA?

The math is identical, but the failure mode is a documentation defect — a wrong revision, missing signature, or incomplete data package — rather than a physical part failure. It targets the paperwork that gates flight acceptance.

Documentation Hours Calculator

This documentation risk score applies FMEA-style severity, occurrence, and detection ratings to the as-run records, travelers, and CDRL deliverables behind a flight build. On space payload and avionics programs, a missing or wrong record can ground a flight unit as surely as a hardware defect, because acceptance data packages are contractual and traceability is non-negotiable. Quality and configuration-management engineers use this score to rank which documentation gaps most threaten flight readiness and to steer audit and review effort. It turns a vague sense that paperwork is behind into a prioritized, comparable number.

What this calculator does

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.
Use it when documentation hours in space payload and avionics manufacturing needs a defensible ranking against other space payload and avionics manufacturing risks for the next review.
It computes a documentation risk priority number by combining severity, occurrence, and detection scores for a given documentation gap or process.

Formula used

Documentation hours risk score = documentation hours severity score × documentation hours occurrence score × documentation hours detection score
Use the same scoring scale across comparable documentation hours risks.

Inputs explained

Documentation hours severity score:
Documentation hours occurrence score:
Documentation hours detection score:

How to use the result

Use it to triage which documentation risks — missing travelers, incomplete data packages, weak review gates — deserve corrective action first.
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.

Current U.S. benchmarks

Global copper trades at $13,484 per tonne (IMF via FRED, May 2026), up 41.5% in a year, and U.S. industrial electricity averages 8.66 cents per kWh. Both feed electrified-hardware unit economics.
Steel mill PPI stands at 348.53 (BLS, May 2026), up 6.7% from a year earlier. New factory orders are up 2.3% year over year (Census).
