5.Research question• 3. what is an agile method?
![Page 9: Agile methods: a comparative analysis Diane Strode-University of Wellington the 19 th Annual Conference of the National Advisory Committee on Computing](https://reader035.vdocuments.mx/reader035/viewer/2022062421/56649e425503460f94b350f7/html5/thumbnails/9.jpg)
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 frameo 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 coveredo method 的獨特性 缺點 : subjective
• 4. 改進 =>summary , objective

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 practitionerso 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 frameo 2.coverage 較高
• 3. 額外加入o Identifiero assumptionso values,o Perspectiveo metrics, and tailorability.
