2. PROTOTYPE MODEL
3. EVOLUTIONARY MODEL
4. SPIRAL MODEL
5. FISH MODEL
1. WATERFALL MODEL:
ADVANTAGES:
1. It is a simple model.
2. Project monitoring and maintenance is very easy.
DISADVANTAGES:
1.Can't accept the new requirement in the middle of the process.
2. PROTOTYPE MODEL

Whenever the customers are not clear with their requirements then this is the best suitable model.
DISADVANTAGES:
a. It is not a full fledged process development model.
b. Prototype need to be built on companies cost.
c. Slightly time consuming model.

3. EVOLUTIONARY MODEL
ADVANTAGES:
Whenever the customers are evolving the requirements then this is the best suitable model. Adding the new requirements after some period of time.
DISADVANTAGES:
1. Project monitoring and maintenance is difficult.
2. Can't define the deadlines properly.
4. SPIRAL MODEL
Ex: Risk-Based Scientific projects.
ADVANTAGES:
Whenever the projects is highly risk based this is the suitable model.
DISADVANTAGES:
1. Time consuming model.
2. Costly model.
. Risk route cause analysis is not an easy task.
NOTE: Cycles depends upon Risk involved in the project and size of the project, Every class has 4 phases, except the last phase.
5. FISH MODEL
ADVANTAGES:

Validation is the process of checking , conducted on the developed product or its related parts in order to confirm weather they are working according to the expectations are not.
VERIFICATION: QUALITY ASSURANCE PEOPLE(Review, Inspections, Audits, Walk through)
VALIDATION: QUALITY CONTROL PEOPLE (Testing)
6. V- MODEL:
ADVANTAGES:
As verification, validation, test management process is maintained. The outcome will be quality product.
DISADVANTAGES:
1. Time consuming model.
2. Costly model.
AGILE MODEL:
Before development of the application, where testers write the test cases and gives to the development team, so that it can be easy for developers to defect free programs.
