Hi All,

Above is a diagram of the “Spiral Model” which is sub divide into 5 categories

1. Risk analysis

2. Prototyping

3. Engineering

4. Planning

5. Review

A key aspect of the spiral model is that it attempts to combine advantages of “top-down and bottom-up concept”

Here are some important advantages of the spiral model :

  • Estimates (i.e. budget, schedule, etc.) get more realistic as work progresses, because important issues are discovered earlier.
  • It is more able to cope with the (nearly inevitable) changes that software development generally entails.
  • Software engineers (who can get restless with protracted design processes) can get their hands in and start working on a project earlier.
