Effective ideation

With a clear problem in hand, you are ready to open up again. Ideation is about generating many possible paths to the goal before you choose one. Most people stop after the first idea that pops up — but the first idea is rarely the best, it is just the nearest.

Techniques that actually work

Free-for-all brainstorming in a group is often dominated by whoever talks loudest. Here are a few structured techniques that produce more and better ideas:

• Classic brainstorming with rules: Set a clear frame — for example "How might we build trust in a dog sitter?" — and note everything without criticizing. Criticism comes later.
• Brainwriting: Everyone writes ideas in silence for a few minutes before sharing. That lets the quiet voices in and avoids groupthink. Pass the sheets on so others build on them.
• SCAMPER: A checklist for twisting an existing idea — substitute, combine, adapt, magnify, put to other use, eliminate, reverse. Perfect when you are stuck.
• "Worst idea": Deliberately ask for the worst solutions you can think of. It loosens the laughter and lowers the bar — and surprisingly often a good idea hides behind a bad one.

Quantity before quality

In this phase, volume is the goal. The more ideas, the greater the chance that some are truly good. The great enemy is the inner critic who says "that won't work" before the idea is even finished. Defer judgment. Write down the unrealistic idea too — it can become the raw material for a realistic one.

A simple rule: never die on the first idea. Ingrid, who works on sustainable packaging for online shops, had only thought "recyclable box." When she forced herself to twenty ideas, up came a deposit system for boxes, packaging the customer could plant, and a subscription service for reusable crates. None of them existed in idea number one.

Build on other people's ideas

Ideas grow when they are allowed to meet. A simple habit from improv theatre is "yes, and…" instead of "yes, but…". "Yes, but" closes; "yes, and" opens. When someone proposes something, try to add rather than object. Even an idea you disagree with can kick off a better idea in you.

This requires a safe space. Make it clear that in this phase there are no stupid suggestions, and that criticism is postponed, not cancelled.

From many ideas to a few concepts

Now you switch mode from opening to choosing. Group the ideas that belong together, and merge related ones into larger concepts. A quick way to prioritize is "dot voting": everyone gets a few stickers or marks to spread across the ideas they believe in most. The ones with the most votes move on.

Choose two or three concepts to carry forward — not one. A little competition between concepts keeps you from locking in too early, and you can test them against each other in the next round.

Constraints spark creativity

It sounds backwards, but limits often produce better ideas than total freedom. A blank page paralyzes; a narrow question inspires. Try adding artificial constraints: "How would we solve this without an app?", "What if it had to be free?", "How would a completely different industry do it?"

Ingrid had her best flash of insight when she asked: "What would a library do?" A library lends things out and takes them back — and there was the seed of a deposit scheme for packaging. Such analogies from other industries are a reliable source of fresh ideas. Change your setting too: a walk or a coffee somewhere new often loosens more than yet another hour at the screen.

Do this now

Set a timer for ten minutes and write at least twenty ideas for your problem statement. Do not stop to evaluate along the way — just fill the sheet. When the timer rings, group the ideas and choose the three you are most curious about. Write one sentence about each explaining what it solves. You will carry these three into the next lesson on value propositions.
