quality management

Basic idea

The processes that ensure a delivered system meets its functional and non-functional requirements: planning quality in, assessing it through reviews and V&V, and improving the organisation’s capability to deliver it (CMM, ISO 9001).

Key facts

• V&V: Verification — building the product right (matches spec). Validation — building the right product (matches user need).
• CMM levels: 1 Initial → 2 Repeatable → 3 Defined → 4 Managed → 5 Optimising.
• Technical reviews: walkthroughs, inspections (Fagan), pair review — defect detection well before testing.
• Quality is built-in, not bolted-on: cost of fixing a defect grows roughly $10\times$ per phase it slips.
