# software\_engineering

## Basic idea

The disciplined practice of building, deploying, and maintaining software at scale: process, project management, quality assurance, programming languages, and frameworks.

## Key facts

* Two macro process families: plan-driven (Waterfall, PRINCE2) and adaptive (Agile, SCRUM).
* Cost estimation: COCOMO, function points, use-case points; tracking via EVA, PERT.
* Quality is built-in, not bolted-on (CMM, V\&V).
