Spiral model

Answer 1

In a linear sequential model, systematic in approach and the principle of

this model suggests - "Can't retrieve to the previous phase". This model is-

(c) Waterfall model

• The waterfall model can be defined as a sequential design process in which progress is seen as flowing steadily downwards just like a waterfall.

• Various phases in the waterfall model are namely- Conception, Initiation, Analysis, Design, Construction, Testing, Production/Implementation, and Maintenance.

• This model does not allow the process to go back to the previous phase to handle changes in requirements.
