Study Notes

The Spiral Model

  • The spiral model, created by Barry Boehm, offers a flexible approach to software development that emphasizes risk analysis, iterative development, and continuous evaluation and feedback.
  • The spiral model consists of distinct phases:

    Planning

    • Defines project objectives, constraints, and possible alternatives.

    Risk Analysis

    • Identifies and assesses potential project risks.

    Development

    • Involves incremental development of the product through iterations.

    Evaluation

    • Reviews progress and reassesses risks in each iteration.
