1. Comparison between DSDM and XP Presented by Paweena Charoentham April 20, 2005

2. Agenda Introduction to Agile software development Overview of XP Overview of DSDM Similarities between XP and DSDM Differences between XP and DSDM Conclusion

3. What is Agile Software Development? Software development methodologies that are intended to reduce that complexity of software engineering Consists of 7 methods Extreme Programming (XP) Scrum Crystal Orange Dynamic Systems Development Method (DSDM) Adaptive Software Development (ASD) Feature-Driven Development (FDD) Pragmatic Programming

4. XP – Extreme Programming Fine scale feedback Test driven development Planning game Whole team (was Onsite customer) Pair programming Continuous process rather than batch Continuous Integration Design Improvement (was Refactor mercilessly) Small Releases Shared understanding Simple design System metaphor Collective code ownership Coding standard or Coding conventions Programmer welfare Sustainable pace (original name: Forty hour week)

5. DSDM - Dynamic Systems Development Method Use Time boxing and MoSCoW principle Incremental and iterative approach Current and imminent needs of business are addressed first

6. Similarities between DSDM and XP Customer involvement in teams Frequent testing Incremental change Rapid feedback mechanisms Fast delivery Focusing on what can and should be done now Small teams Developers are expected to be multi-skilled

7. Differences between DSDM and XP

8. Differences between DSDM and XP (Cont. 1)

9. Differences between DSDM and XP (Cont. 2)

10. Differences between DSDM and XP (Cont. 3)

11. Conclusion DSDM and XP aim to solve the same problem: delivering good systems in short timescales. XP focuses on the act of programming, which is treated very lightly indeed in DSDM. DSDM provides a controlling framework into which XP can be plugged. DSDM and XP are complementary. Combining the two gives a controlled framework with robust programming practices.
