Software Development Life Cycle

UML is a software development life cycle or process independent language. But to get most out of UML, the software development process should have the following properties:

• Use case driven
• Architecture centric
• Iterative and Incremental

Rational Unified Process (RUP) is a software development process framework developed by Rational Corporation which satisfies the above three properties. The overall software development life cycle can be visualized as shown below:

Critical activities in each phase:

Inception:

• Business case is established
• 20% of the critical use cases are identified

Elaboration:

• Develop the architecture
• Analyze the problem domain (80% of use cases are identified)

Construction:

• Source code
• User manual
• Verification and validation of code

Transition:

• Deployment of software
• New releases
• Training
