4. Problems associated with the Waterfall Model…
Real Time Projects
Uncertainty about requirements
Long Procedure

5. Prototype Model
Developed on the assumption that it is often difficult to know all of your requirements at the beginning of a project.

6. Various steps involved in Prototype Model:
Requirements Definition/Collection
Design
Prototype Creation/Modification
Assessment
Prototype Refinement
System Implementation

7. Problems associated with the Prototype Model
Prototyping can lead to false expectations.
Prototyping can lead to poorly designed systems.
