# Software quality
## MicroSim spec
- **Recommended sim type:** composite / metric
- **Microsimmability score:** 74/100
- **Layout:** drawing region (canvas) on top; control region (sliders/buttons) below.
### Parameters (tunable controls)
- `Defect density`
- `Attribute weights`
- `Test coverage`
### What animates
A weighted quality index aggregates sub-attribute sliders; the composite score moves as defect [[Density|density]] and coverage change.
### Learning objective
Relate an overall quality index to weighted sub-attributes.

## Concept summary
Software quality is the overall degree to which software meets its requirements and stakeholder expectations across many attributes.
## Build checklist
- [ ] Claim it: set `status: in-progress` + `lease` + `leased_at`
- [ ] Write the child page explaining the concept (tie it back to system quality attributes)
- [ ] 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: Software quality
let controls = {};
function setup() {
// createCanvas(...); create sliders for the parameters above.
}
function draw() {
// background(...); read controls; render composite / metric; respond live.
}
```
