1. Concentration claim
In aerospace programs, most expensive cost/schedule/safety pain concentrates in a few mass, interface, certification, reliability, supplier, and specialist bottlenecks — not evenly across the risk log.
2. Hard anchors
- DO-178C — software considerations in airborne systems; assurance rigor tied to failure severity (unequal attention by design). https://www.rtca.org/standards/ (RTCA DO-178C product family; cite standard name + severity-tier idea)
- AS9100 — aerospace quality management; risk/process discipline. https://www.sae.org/standards/content/as9100d/
- Tsiolkovsky rocket equation — mass growth amplifies propulsion need (textbook mechanism). https://www.grc.nasa.gov/www/k-12/airplane/rockeq.html
- ICD / FMEA / FMECA — industry practice artifacts (pattern); no single universal dataset claiming exact 80/20.
2b. Field 80/20 examples
| Approx % claim | Field / context | Source | Where in article |
|---|---|---|---|
| ~80% of defects from ~20% of causes (“vital few”) | Quality / reliability engineering | Juran popularization of Pareto in QC; ASQ/Pareto chart practice | FMEA / quality section |
| ~20% of bugs → ~80% of crashes | Software assurance (DO-178C-adjacent) | Ballmer/Microsoft 2002 (CRN) | Certification / SW verification section |
3. Original observation (only-on-8020)
Sample top-10 Pareto risk register for a notional smallsat avionics program — labeled Illustrative program composite — showing how weekly attention maps to six bottleneck classes.
4. Ignored majority
Equal review of all ICDs; full 80-row risk log discussed quarterly; broad inspection checklists while top FMEA modes ignore test hours.
5. Composite policy
| Scenario | Keep as Illustrative? |
|---|---|
| Smallsat mass/ICD/FMEA examples | Yes — labeled |
| Top-10 register | Yes — Illustrative program composite |
6. Vital few
Mass margin consumers; unstable ICDs; orphaned verification; top FMEA modes; long-lead suppliers; scarce specialists.
7. Device budget
