2. 1 Introduction • 2 Systems development methodology • 3 The agile methods • 4 The evolution of agile methods • 5 Research question • 6 Comparative analytical frameworks • 7 A framework for agile methods • 8 Reasons for selecting early agile methods • 9 Results • 10 Conclusions

3. 1.Introduction • 1回答核心問題”What is agile method?” • 2提供分析framework • 3定義development method 以及agile的發展歷史 • 4使用framework在method間的選擇與比較作為應用及其結果

4. 2.Systems development methodology • 1定義Systems development methodology:

5. 3.The agile methods • 1.Extreme programming (Beck, 1999, 2000), • 2.Crystal Methods (Cockburn, 2002), • 3.Adaptive Systems Development method (J. A.Highsmith, 2000), • 4.Dynamic Systems Development Method(Stapleton, 1997), • 5.Scrum(Schwaber & Beedle, 2002),

6. 4.The evolution of agile methods • 1.object-orientation, • 2.evolutionary development, • 3.internet technologies • 4.methodology engineering.

7. 5.Research question • 1.認為”agilemethod”並未從本質上定義(Reifer) • 1.Learn • 2.Classify • 3.Compare , Select • 2.五種早期提出的agile method • 1.共同特性,差異 • 2.不適用於何種環境

8. 5.Research question • 3.what is an agile method?

9. 6.Comparative analytical frameworks • 1.作者定義 • From: philosophy，property方面 • 分析:同異,優缺及特性間的關係用以判斷選擇合適的method • 2.用frame • 1.用frame的原因 • 2.為避免”limited expressive power” • 3.contribution of this study [Abrahamssonet al(2003)]. • 是否為agile method 缺點 ：如何決定? • 1.incremental • 2.cooperative • 3.straightforward • 4.adoptive • Feature缺點 ：not covered • method的獨特性缺點 ：subjective • 4.改進=>summary，objective

10. 7.A framework for agile methods • 1.為何採用Avison and Fitzgerald (1995a, 2003). • 1.簡單,易理解 • 2.設計給practitioners • 3.加入了Abrahamsson et al.(2002) • 2.本framework優點 • 1.大量採用先前使研究的frame • 2.coverage較高 • 3.額外加入 • Identifier • assumptions • values, • Perspective • metrics, andtailorability.

11. 7.A framework for agile methods

12. 8.Reasons for selecting

13. 9.Results • 1.What are the properties ofindividual agile methods? • ANS: The analytical framework for agile methods • 2.What are the properties commonto all agile methods? • ANS:

14. 9.Results • 3.What are the differences betweenagile methods? • ANS: • 4.What properties are unique toagile methods within the set of agile methods? • ANS: • In XP：”test-first development”” pairprogramming””theuse of a system metaphor”

15. 9.Results • 5.What combinations of agilemethods are possible? • ANS: • 6.What are the published problemswith agile methods? • ANS:

16. 10.What is agile method: • 1.一種開發技術用以支援管理在變動商業環境下的incremental及iterativedevelopment • 2.增強team與customer間的關係 • 3.用以更早產出程式,藉由: • Communication • Feedback • Learning • Frequent meeting in preference to than modeling and documentation • 4.適應已存在的軟體開發技巧已達成目標
