## MicroSim spec
### Parameters (tunable controls)
- `Severity S` · 1–10 · impact rating of the failure mode
- `Occurrence O` · 1–10 · likelihood rating of the failure mode
- `Detection D` · 1–10 · difficulty of detecting it before effect (RPN=S*O*D)
### What animates
A [[Bar_chart|bar chart]] of failure modes reorders as the RPN (S*O*D) recomputes.
### Learning objective
Show how severity, occurrence, and detection combine into a risk priority number.

## Concept summary
Failure mode and effects analysis (FMEA; often written with "failure modes" in plural) is the process of reviewing as many components, assemblies, and subsystems as possible to identify potential failure modes in a [[System|system]] and their causes and effects. For each component, the failure modes and their resulting effects on the rest of the system are recorded in a specific FMEA worksheet.
## Build checklist
- [ ] Claim it: set `status: in-progress` + `lease` + `leased_at`
- [ ] Write the child page explaining the concept (tie it back to Systems Engineering)
- [ ] Finalize parameter ranges and defaults
- [ ] Implement the p5.js sketch (drawing + control regions)
- [ ] Add caption + the learning objective on the page
- [ ] Set `status: done`
## p5.js sketch
```javascript
// MicroSim: Failure mode and effects analysis
const ARTICLE = "Failure_mode_and_effects_analysis";
let p1, p2, p3;
function setup() {
createCanvas(720, 520);
pixelDensity(2);
// reliability-sim sim — create the three sliders described above:
// Severity S (1–10), Occurrence O (1–10), Detection D (1–10).
// TODO: build labelled sliders in the control region (below the drawing region).
}
function draw() {
background(248);
// TODO: read p1/p2/p3; render the reliability-sim in the drawing region and respond live.
// TODO: HUD — title + en.wikitube.io/wiki/Failure_mode_and_effects_analysis + control hints + live readouts.
}
```
