M otivation

Motivation

  • 多數的敏捷開發團隊(Agile software development, ASD team)做出的決議(Decisions),大多仰賴過去的經驗以及比較所得到,少有一個標準化的model


Descriptive decision theory ddt

Descriptive Decision Theory(DDT)

  • DDT多著重在真實世界人類的行為及思考

  • 本研究以DDT為藍本

    • 研究 Tacticaldecision 以及 Strategic decision 是如何被ASD所決定

    • 辨識出這些決議過程中的障礙(Obstacles)

    • 整個team的健康度

Review

Sprint

Planning

Sprint cycle , 通常為2-4週


Research design

Research Design

  • Focus Group

  • Data Collection & Analysis


Analysis

Analysis

  • 四個周期的decisions made

    • Sprint Planning

    • Sprint Execution

    • Sprint Review

Analysis (cont.)

  • Obstacles

    • 人們對於commit的意願不高

    • 優先權衝突

    • 老闆說得是

    • 決議不會讓所有人都信服

    • 團隊裡面並不是每個人的能力都相等

    • 太過於民主


Conclusions

Conclusions

  • Tactical decision 的數量大於 Strategic decision

  • Obstacles 不僅僅對於Sprint Planning 有影響,對於Sprint Execution 和 Sprint Review也有很大的影響
