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