The incremental process model breaks down software development into standalone modules that each pass through requirements, design, implementation, and testing phases independently. Each subsequent release of a module adds new functionality to the previous release until the full system is complete. This allows for easier testing and debugging, and gives customers a chance to provide feedback after each component delivery. However, proper planning and design is needed to successfully integrate components without consuming significant time to fix issues.

1. Incremental
PROCESS MODEL

2. INCREMENTAL MODEL
• Incremental Model is a process of software development where
requirements are broken down into multiple standalone modules of
software development cycle.
• Each module (independent units) passes through the requirements,
design, implementation and testing phases.

3. INCREMENTAL MODEL
• Each subsequent release of the module adds function to the
pervious release.
• The process continues till the complete system is achieved

4. EXAMPLE
• When we work incrementally we are adding piece by piece but
expect that each piece is fully finished
• Thus keep on adding the pieces until it’s complete

5. ADVANTAGES
• Easier to test and debug
• Customer feedback is received after the delivery of
each component
• more flexible
• Risk of requirement changes is reduce

6. DISADVANTAGES
• Need good planning to integrate the components
• Need proper design to integrate the components
• Each iteration phase is rigid and does not overlap each other
• Rectifying a problem in one unit requires correction in all the
units and consumes a lot of time
• More expensive

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