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 ”agile method” 並未從本質上定義 (Reifer) o 1.Learn o 2.Classify o 3.Compare, Select 2. 五種早期提出的 agile method o 1. 共同特性, 差異 o 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 o From: philosophy ， property 方面 o 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 o 1. 用 frame 的原因 o 2. 為避免 ”limited expressive power” 3. contribution of this study [ Abrahamsson et al(2003 )]. o 是否為 agile method 缺點 ：如何決定 ? 1.incremental 2.cooperative 3.straightforward 4.adoptive o Feature 缺點 ： not covered o 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). o 1. 簡單, 易理解 o 2. 設計給 practitioners o 3. 加入了 Abrahamsson et al.(2002) 2. 本 framework 優點 o 1. 大量採用先前使研究的 frame o 2.coverage 較高 3. 額外加入 o Identifier o assumptions o values, o Perspective o metrics, and tailorability.

11. 7.A framework for agile methods

12. 8.Reasons for selecting

13. 9.Results 1.What are the properties of individual agile methods? o ANS: The analytical framework for agile methods 2.What are the properties common to all agile methods? o ANS:

14. 9.Results 3.What are the differences between agile methods? o ANS: 4.What properties are unique to agile methods within the set of agile methods? o ANS: In XP ： ”test-first development”” pair programming””the use of a system metaphor”

15. 9.Results 5.What combinations of agile methods are possible? o ANS: 6.What are the published problems with agile methods? o 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 iterative development 2. 增強 team 與 customer 間的關係 3. 用以更早產出程式, 藉由 : o Communication o Feedback o Learning o 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
