Iterative software development involves breaking projects into short iterations where cross-functional teams work to develop and test incremental releases. Each iteration results in a stable, integrated release. Core activities within each iteration include requirements gathering, analysis, design, development, testing, and deployment. This allows continuous integration and feedback between developers, customers, and management.

4. What is an iteration
•A self contained mini-project with a well
defined outcome: a stable, integrated, and
tested release

5. Rational Unified Process

7. Core S/W Development Disciplines
For Each Iteration

8. Teams
•Core Dev Team
o Architecture
o Analysis
o Design
o Implementation
o Testing
•Customer Team
o Define problems to be solved, things to be built,
changes to business processes
•Management Team
o Ensure that customer, business and development

9. The Developer’s perspective

10. Team Lead Perspective
•A time boxed mini-project that results in the
production of a significant new release of
the software

11. Each iteration results in a
“RELEASE”

12. Integration of Iterations

13. The Customer’s perspective

14. Requirements
•Software Requirements Gathering
•Business Process Modeling (As-Is)
•UI prototypes / wireframes

15. Analysis
