Explain about the incremental model.
- Have similar phases as the waterfall model.
- Phases are

Design.
Code.
Test.
- Incremental model delivers series of releases to customers known as increments.
- The first increment is known as core product. Here only the document processing facilities are available.
- Second increment, more sophisticated document forming and processing facilities are available.
- Next increment spelling and grammar checking facilities are given.
Merits
- This model can be adopted when there is less number of people included in the project.
- Technical risks can be managed with every increment.
- For a very small time span, at least core product can be delivered to the customer.
