1. Comparison between DSDM and XP Presented by
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
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)
Dynamic Systems Development Method (DSDM)
Adaptive Software Development (ASD)
Feature-Driven Development (FDD)
4. XP – Extreme Programming Fine scale feedback
Test driven development
Whole team (was Onsite customer)
Continuous process rather than batch
Design Improvement (was Refactor mercilessly)
Small Releases Shared understanding
Collective code ownership
Coding standard or Coding conventions
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
Rapid feedback mechanisms
Focusing on what can and should be done now
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.
