Fault Tree Analysis (FTA)-- The Beautiful Beast
- Single Most Beautiful Tool in a Systems Safety Engineer’s Arsenal
- Deceptively simple looking, yet has nuances and rules which are often not understood
- FTA can eat you alive both in time and complexity!
- Can find design problems as no other method can
- Widely Used, Mostly Abused in Space Industry
- Many fault trees are developed -- few are developed well
- Too often thought of as a graphical Hazard Analysis (HA) or Failure Modes & Effects Analysis (FMEA)
- Too rarely used to full potential as an Analytical Tool!
