The incremental process model involves dividing a software project into separate builds or modules. Each module goes through requirements, design, implementation, and testing individually before being integrated into the overall product. Subsequent releases add new functionality to the previous version until the full system is complete. The incremental model allows for flexibility, lower costs, early delivery of working software, and easier management of risk compared to the waterfall model. However, it requires good upfront planning and a clear definition of the whole system requirements. This model is often used for web applications where major requirements are known but details can evolve over time.

2. DEFINATION
In incremental model the whole requirement is divided
into various builds.
Each module (independent units) passes through the
requirements, design, implementation and testing phases.
The incremental build model is a method of software
development where the product is designed.
Implemented and tested incrementally until the product is
finished.

3. DEFINATION
Each subsequent(coming after something in time)
release of the module adds function to the previous
release.
The process continues till the complete system is
achieved.

6. ADVANTAGES OF INCREMENTAL MODEL:
This model is more flexible, less costly to change
scope and requirements.
It is easier to test and debug during a smaller
iteration.
In this model customer can respond to each built.
Lowers initial delivery cost.
Easier to manage risk because risky pieces are
identified and handled during it’s iteration.
Generates working software quickly and early during

7. DISADVANTAGES OF INCREMENTAL MODEL:
Needs good planning and design.
Needs a clear and complete definition of whole system
before it can be broken down and built incrementally.
Total cost is higher than waterfall.

8. WHEN TO USE THE INCREMENTAL MODEL:
Mostly such model is used in web applications and
product based companies.
This model can be used when the requirements of the
complete sysyem are clearly defined and understood.
Major requirements must be defined; however, some
details can evolve with time.
There is a need to get a product to the market early.

9. INCREMENTAL VS ITERATIVE MODLE
INCREMENTAL MEANS:
 It writes part one.
 It writes part two.
 It writes part three, until the book is
finished.
ITERATIVE MEANS:
 It writes loads of stuff that is a
complete mess,
 It go throwing out the irrelevant,
expanding on the important bits, and
sorting out the structure.
 It goes through it again now it can start
to see the shape of it, sorting it some
more.
 It goes through it yet again,etc, intil it’s
goodenough!
