Go for Lots of Ideas
Brainstorming means thinking up many ideas, not just one. If books slide off your desk, you could think of a basket, a shelf, a clip, a box, or a stretchy band. That is five ideas instead of one. The more ideas you make, the better your chances of finding a great one. Right now the goal is quantity, which means how many. You pick the winner later, not now.
Rules That Keep Ideas Flowing
Good brainstormers follow a few rules. First, write down every idea, even the silly ones. Second, do not judge yet, which means do not say that is bad. Save judging for later. Third, build on each other's ideas to make new ones. If you feel stuck, just ask yourself one more way to solve this. There is always one more idea waiting for you to find it.
Worked examples
Your books slide off your desk. Brainstorm some ideas.
- Think of a basket to hold them.
- Keep going: a shelf, a clip, a box, a band.
- Write every idea down without judging it.
Answer: You now have five ideas instead of one.
A teammate says an idea is weird. What do you do?
- Do not throw the idea out yet.
- Write it down and keep brainstorming.
Answer: Keep the weird idea, because judging comes later.
Activity
Sort each card into the bin that shows where the team is in the design process
Practice
Think of four ways to carry many small toys.
Ask yourself one more way to solve a problem.
Common mistakes to avoid
- Stop after one ideaStopping at one idea hides better options from you.
- Judge ideas right awayJudging too early stops good ideas from coming out.
Check your understanding
During brainstorming, a teammate says 'That idea is too weird — let's skip it.' What should the team do instead?
Why do engineers come up with lots of ideas instead of just one?
Your team's problem is: 'Our plant-watering robot gets stuck on the rug.' You already thought of making the wheels bigger. What should you do next to be a good brainstormer?
Recap
Brainstorming means making lots of ideas before you choose. The goal is quantity, not a quick winner. Write every idea down and do not judge yet. More ideas give you more good options to compare later.
Reflect
What is one more idea you could add right now?
