software development phase and testing
phase takes place in a linear sequential
manner in V shape.

6. Advantages & Disadvantages
Advantages:
Ø It is simple to use and understand since V-Model is of sequential
type.
Ø The corresponding testing phase of the development phase is
planned in parallel.
Ø This model works well for smaller projects where requirements
are very well understood.
Disadvantages:
Ø We cannot add new requirements in between of development
phases.
Ø We cannot get a working model of a software unless development
phase is complete.
