Design Process of This Class

The Purpose of This Class

EDP-A is designed as a preparation / training for EDP-B/C

• The sponsor companies will expect "WOW" solutions

• "Design Thinking" (w/ plain prototype) is not enough to make that happen

• You should go into "Engineering Design" (w/ rich prototype) instead, so we'd like you to learn what the DTF class did not cover

• Sorry for students who won't take EDP-B/C ...

Stages of Prototypes

Schindlholzer, Bernhard, Falk Uebernickel, and Walter Brenner. "A method for the management of service innovation projects in mature organizations." (2011).

P1:Critical Function Prototype 💡

• to ideate critical functional requirements of a potential solution with paper or so

P2: Darkhorse Prototype 🐴

• to broaden the solution space

P3: FunKtional (Integrated) Prototype 🐒

• to combine the different prototypes that have been developed in the previous stage

P4: Functional Prototype 🛩

• to define the scope of the final solution that will be delivered at the end of the project

P5: X-is-Finished Prototype ✈

• to finish one functionality or feature of the final solution

P6: Final Prototype 🚀

• to integrate into a coherent concept, in order to go into mass-production

User's Imagination

Exploit User's Imagination 💭

- Carefully choose imaginative users (Early Adapters)

- Test with plural (at least 5) users

- Use "Wizard of Oz" 💫

- Prepare various types of prototypes

• Users cannot do absolute evaluation, so let users choose better one

• [TIP] separate one prototype into two different prototypes ➡

Two types of Prototypes

Work-Like prototype 🤖

• with little-to-no resemblance to the intended final product

Look-Like prototype 🎨

• with little-to-no intended functionality

How to Test With Users1. Set the context.

• Put users in the situation where the prototype is appropriately used.

2. Show don’t tell about the prototype.

• Put your prototypes in the user’s hands and give just the minimum explanation.

3. Actively observe.

• Watch how they use (and misuse!) what you have given them. Don’t “correct” what user is doing.

4. Follow up with questions.

• Choose questions which can decide whether you should improve or change the prototype.

• Use "Value Proposition Statement" as reference ➡

https://dschool.stanford.edu/resources/the-bootcamp-bootleg


Value Proposition StatementYou should break this down to sub value propositions.

User Test should include falsifiable hypothesis

Decision-making is difficult, but important

😄 If the hypothesis is true ...

• You should improve the prototypes and continue tests

😩 If the hypothesis is false ...

• You should think where to fix, then change and continue tests (function? looking? user? hypothesis? context? usage?)

• If all of the hypothesis are false, it's no problem. You should learn a lot.

Use "Feedback Capture Grid" to get Feedback


It's easy to use, but ... observation is more important


There is no "RIGHT" user test

You should get "convincing" testimonials

REFLECTION

- Take a LARGE sticky note. (or combine two 75x75 post-it notes)

- Write down your name and dept on the top

- Write about today's class and/or yourself (Japanese is OK) :

• Keep (Good thing)

• Problem (Bad thing)

• Try (Improvement)

- Post on the whiteboard.

Name and Dept - Keep - Problem- Try
