2. Maker
 有人想到個 Idea
 一伙人討論
 誰會需要
 怎麼滿足需要的人
 怎麼回本
 制定功能和操作方式
 作 prototype ，調調改改
 找人來試，改進再試
 拿去賣，邊賣邊改

3. 球隊
 不斷練球
 不斷演練
 不斷 Play
 不斷檢討，基於數據和事實
 球員地位平等
 球員有主要進攻防守位置，但也要補位
 一直求進步
 一直想對策

4. Lean UX = Maker + 球隊
 每個 Feature 的產生，都基於嚴謹的假設 :
 明確的服務對象 ( 人物模型 )
 評估對團隊的效益 ( 有明確指標驗證 )
 重點在學到 know-how
 每個 Feature 的產生，都來自於集思廣義
 相信團隊的智慧勝過個人 (Design Studio)
 演練後將戰術標準化
 白紙測試 + Style Guides
 不斷 Play – MVP (Minimum Viable Products)
 不斷檢討，集思廣義
 Collaborative and Continuous Discovery
 Open Minded - 擁抱矛盾與不明朗的資訊

5. 3 Foundations
 Design thinking
 Agile software development
 Lean Startup method

6. Design thinking - CEO of IDEO
 創意來自於對人們的直接觀察，包含：
 人們生活上想要和需要的
 人們對產品的生産包裝銷售服務方式的好惡
 運用設計師的感性
 運用科技所及的方法和可行的商業策略
 帶給顧客價值
 帶來市場機會

7. Agile software development
 Individuals and interactions over
processes and tools.
 Working software over
comprehensive documentation.
 Customer collaboration over contract
negotiation.
 Responding to change over following
a plan.

8. Lean Startup method
 Feedback loop called "build-measure-learn"
- minimize project risk, teams building
quickly, learning quickly
 Minimum Viable Products (MVPs) - ship
them quickly to begin the process of
learning as early as possible
 Each design is a hypothesis aiming at
fulfilling some specific customer's needs.
Test the hypothesis with MVP and learn
quickly.

9. Process
 Assumptions – what we believe
 Hypotheses – specific areas to
experiment
 Outcomes – signal from market to
validate hypotheses
 Personas – models of the people for
whom we solve a problem
 Features – the changes drive the
outcomes we seek

10. Assumptions
 Declaring Assumptions
 Problem Statement

11. Declaring Assumptions
 Analytics reports that show how the current
product is being used
 Usability reports that illustrate why
customers are taking certain actions in your
product
 Information about past attempts to fix this
issue and their successes and failures
 Analysis from the business stakeholder as
to how solving this problem will affect the
company’s performance
 Competitive analyses that show how
competitors are tackling the same issues

12. Problem Statement
 [Our service/product] was designed
to achieve [these goals]. We have
observed that the product/service
isn’t meeting [these goals], which is
causing [this adverse effect] to our
business. How might we improve
[service/product] so that our
customers are more successful based
on [these measurable criteria]?

13. Assumptions Worksheet

5. The customer can also get these
additional benefits _______ .
6. I will acquire the majority of my
customers through _______ .
7. I will make money by _______ .
8. My primary competition in the market will
be _______ .
9. We will beat them due to _______ .
10. My biggest product risk is _______ .
11. We will solve this through _______ .
12. What other assumptions do we have
that, if proven false, will cause our
business/project to fail? _______
User Assumptions
1. Who is the user?
2. Where does our product fit in his work or
life?
3. What problems does our product solve?
4. When and how is our product used?
5. What features are important?
6. How should our product look and behave?

14. Hypotheses statement
 We believe [this statement is true].
 We will know we’re [right/wrong]
when we see the following feedback
from the market:
[qualitative feedback] and/or
[quantitative feedback] and/or [key
performance indicator change].

15. Subhypotheses
 We believe that [doing this/building
this feature/creating this experience]
for [these people/personas] will
achieve [this outcome].
 We will know this is true when we see
[this market feedback, quantitative
measure, or qualitative insight].

16. Outcomes
 Key performance indicators (KPIs)
the company should pursue next.

17. Personas

18. Features
We will for In order to
achieve
[create this
feature]
[this
persona]
[this
outcome]
… … …

19. Collaborative Design
 Design Studio
 Problem definition and constraints (15-45
minutes)
 Individual idea generation (diverge) (10
minutes)
 Presentation and critique (3 minutes per
person)
 Iterate and refine (emerge) (5-10 minutes)
 Team idea generation (converge) (45 minutes)
 Style Guides
 Big bang
 Slow drip

20. MVPs
The sooner we can find which
features are worth investing in, the
sooner we can focus our limited
resources on the best solutions to our
business problems
 To maximize learning
 To deliver value to your customers
 Prototyping – paper, clickable
wireframes, coded prototypes

21. Continuous Discovery

22. 流程範例 (Lean UX + Scrum)

23. 組織文化轉變

 合作的能力
 新技能的學習力
 創造跨功能的許多小團隊
 創造開放合作的環境
 不靠英雄主義
 速度第一
 著重在問題解決

 向上向外管理，不悶著頭作

24. 必要能力
 設計能力
 開會技巧與會議主持
