Question

Difference btw waterfall modell and incremental model

Answer 1

Waterfall include following steps: Requirements, design, implementation, testing and integration and maintenance. Waterfall model cannot be tracked back. It is used for large projects. It was purposed by computer scientist Winston Walker Royce in 1970.

Incremental model consists of following steps: Requirement, Specification, Architectural design, Implementation, Maintenance and retirement. It is combination of undeviating and iterative model. It can straightforwardly accept change. It was purposed by IEEE in 2003 due to defects in waterfall model. As waterfall is not suitable for all models.

Answer 2

Answer:

Waterfall Model is also known as Classical/Traditional Model. Sometimes It is referred as linear-sequential life cycle model because all phases involve in this model completed one by one in linear fashion. In this model, we get software after completion of all coding phase. This model is basically used for small projects. There exist only one cycle in waterfall model.

While in Incremental Model Multiple development cycles take place and these cycles are divided into more smaller modules. Generally a working software in incremental model is produced during first module Each subsequent release of the module adds function to the previous release. In incremental model, process continues till the complete system is achieved.
