When the requirements are clear and enhancing regularly, organizations can follow spiral
model to release the software version by version.

Spiral Model
  1. From the above diagram requirement gathering will be done at first and later design
    this will be continued till the maintenance stage.

    and again with the new requirements, analysis will be done. This cycle will be repeated
    for every new version of the software.

  4. Doesn’t work well for smaller projects.
