Spiral Model overview
A risk-driven software development process combining iterative development with systematic aspects of waterfall. Development progresses through multiple spirals, each containing four phases: Planning (objectives, alternatives, constraints), Risk Analysis (identify and resolve risks through prototyping), Engineering (develop and verify), and Evaluation (review and plan next spiral). Radial dimension represents cumulative cost, angular dimension represents phase progress.

A risk-driven software development process combining iterative development with
systematic aspects of waterfall. Development progresses through multiple spirals,
each containing four phases: Planning (objectives, alternatives, constraints),
Risk Analysis (identify and resolve risks through prototyping), Engineering
(develop and verify), and Evaluation (review and plan next spiral). Radial
dimension represents cumulative cost, angular dimension represents phase progress.
