Q What is the advantage of utilizing prototype software development model instead of waterfall model? As well explain the effect of defining a prototype on the overall cost of the software project?
Ans: The waterfall model: This is the classic Software Development Life Cycle (SDLC) model with a linear and sequential method that has goals for each development phase. The waterfall model makes simpler task scheduling because there are no iterative or overlapping steps. One disadvantage of the waterfall is that it doesn't allow for much revision.
The prototyping model: In this model a prototype is an early approximation of a final system or else product is built, tested and then reworked as necessary until an acceptable prototype is finally achieved from which the complete system or product can now be developed.
Re-Engineering cost factors:- 1) The amount of the software to be re-engineered. 2) The tool support available for re-engineering. 3) The extent of the data conversion
