Explain Evolutionary prototyping

Objective:

• The principal objective of this model is to deliver the working system to the end-user.
• Example-AI systems.

Advantages

• Fast delivery of the working system.
• User is contained while developing the system.
• More useful system can be delivered.
• Specification, design and implementation work is co-ordinated manner.

Problems

• Management problems
• Maintenance problem
• Verification

Incremental Development

• After designing the overall architecture the system is developed and delivered in series of increments.
