The Incremental Process Model

•Main characteristics
–Hybrid model that combines elements of the waterfall and evolutionary paradigms.
–The specification, design, and implementation phases are broken in smaller increments.

•Advantages
–Provides better support for process iteration.
–Reduces rework in the software construction process.
–Allows early delivery of parts of the system.
–Supports easier integration of sub-systems.
–Lower risk of project failure.
–Delivery priorities can be more easily set.

•Disadvantages
–Mapping requirements to increments may not be easy.
–Common software facilities may be difficult to identify.
–Some decisions on requirements may be delayed.

•Applicability:
–When it is possible to deliver the system “part-by-part” .
