Weaknesses of the Prototype model - Project management (PMP)

Explain the weaknesses of the prototype model.

Weaknesses of the Prototype model are:

a) Focusing on the prototype can mislead developers from understanding the actual desired system.
b) End users get confused, believing the prototype to be the complete system
c) Developers might misunderstand end users objectives.
d) Developer might get too involved in prototype and deviate from the actual system that the prototype must be converted into.
e) Expensive as prototypes need a lot of effort and time. It may take a lot of work to be done for very less needed work to be achieved.
Explain when to use the Prototype model - Project management (PMP)
Prototype model should be used when the desired system needs to have a lot of interaction with the end users.....
Rapid application development (RAD) SDLC model - Project management (PMP)
RAD involves iterative development along with creation of prototypes. It uses interactive use of techniques and prototypes....
