Method: Worst Possible Idea
Step 1: Choose the problem space you’re addressing.
Step 2: Think of worst possible ideas to solve the problem and record them on a
sticky note. Try to think of ideas that are extremely bad, terrible, silly,
impossible, and possibly illegal!
Step 3: Share your ideas with your team.
Step 4: Review the ideas and use them to prompt a new way of thinking about the
problem. Consider:
• What are their attributes, and why do they make it a bad idea?
• What is the opposite of the bad ideas?
• How can the ideas be merged or modified?

Design problems: “wicked” framings
Wicked framings (not tame)
- The starting and end points are only partially defined
- Complex technological-human interactions
- Many stakeholders, agendas, interpretations
- Not neatly defined, knowledge across disciplines necessary
- Multiple causes-effects at multiple scales
- Impossible to fully anticipate future states

Design Dispositions
No “definite list”, but often identified:
1. Identify your assumptions, Don’t rush to solve
2. Be curious and inquisitive: What? Why? How? Who?
3. Think in metaphors, generate analogies
4. Seek & interpret feedback constructively
5. Develop your initial ideas
6. Represent your ideas through storytelling
7. Examine your ideas through sketches & prototypes
8. Suspend disbelief to imagine ethical futures
9. Think of consequences, anticipate futures
