Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

If project is the enhancement of existing system, which model is best suited?

A	Waterfall model
B	Prototyping model
C	Iterative enhancement model
D	Spiral model

Explanation:

Detailed explanation-1: -4-It is more common to waterfall model, but here the development process is based on formal mathematical transformation of a system specification to an exactable program.

Detailed explanation-2: -Evolutionary Prototyping This model is helpful for a project which uses a new technology that is not well understood. It is also used for a complex project where every functionality must be checked once.

Detailed explanation-3: -Iterative Enhancement Model is divided into three stages: Analysis of software system. Classification of requested modifications. Implementation of requested modifications.

Detailed explanation-4: -The iterative enhancement model is divided into three stages: Implementation of requested/asked modifications. Classification of requested modifications. Analysis of software system.

Detailed explanation-5: -One can choose Waterfall Model if the project development schedule is tight. Explanation: Real projects rarely follow the sequential flow and iterations in this model are handled indirectly. This changes can cause confusion as the project proceeds thereby delaying the delivery date.
