Detailed explanation-1: -The waterfall model is a relatively linear sequential design approach to develop software projects. The spiral model is a risk driven process model generator for software projects. In waterfall model, the customer involvement is minimum. In spiral model, the customer involvement is high.
Detailed explanation-2: -The Spiral methodology is known for being one of the most flexible SDLC models. It has a repetitive cycle-the project goes through four stages (planning, risk analysis, engineering, and evaluation) over and over in a “spiral” formation until it is fully completed.
Detailed explanation-3: -The spiral model has four phases: Planning, risk analysis, product development and next phase planning or Evaluation. A software project repeatedly passes through these phases in iterations (called Spirals in this model).
