Broad Thinking Creates Options, Deep Thinking Creates Impact

Another invitation to a brainstorming session—many now see these workshops as a waste of time. Too often, the results are disappointing, despite the seemingly simple task: we need a few good ideas. One of the most common mistakes? Too much breadth, too little depth.
Let’s illustrate this with an example: The challenge was simple and has been tackled in countless creativity workshops: “How can we reduce waiting times at supermarket checkouts?” After 30 minutes of brainstorming, the ideas were predictable: more checkout lanes, self-service stations, priority lines, RFID shopping carts …
The mood: Frustration – this felt like a waste of time. If we had stopped here, the creative process would have failed.
Challenging Assumptions
Instead, we questioned the assumptions behind the supposed problem, e.g. it is an assumption that waiting time in supermarket is negative and should be reduced.
An alternative view could be: For supermarkets, time of their customers in-store is an opportunity. Why shorten it?
From this, a new search field emerged: “How can we make use of customers’ waiting time?”. Another round of brainstorming generated a wide range of ideas: informing customers about new products, sharing useful knowledge (e.g., how to pick a ripe melon), creating an engaging shopping experience, up to a dating place for singles. Some were abstract but promising – so we went deeper.
From Abstract to Actionable
We focused on knowledge-sharing and developed concrete ideas:
- Display recipes and cooking tips
- Experts (e.g., butchers, suppliers) share insights
- Customer peer groups exchange shopping tips
Another approach – turning shopping into an experience – led to a surprising idea. A participant joked, “I always pick the slowest line!” Another responded, “I bet I’m worse!”
This sparked an idea: checkout betting.
Instead of dismissing it, we explored it further:
- What’s the bet? Discounts, small prizes?
- Who bets? Customers, the store, cashiers?
- What’s the benefit? Turning frustration into fun, distracting customers during wait times.
Legal concerns (gambling regulations, fairness) forced another iteration. The solution? Cashiers bet against each other on checkout speed for a bonus. This idea was refined further—until it became viable … and indeed it could shorten waiting time.
The Key Takeaway
Creativity thrives on iteration—first broad, then deep. This cycle, repeated over hours or weeks, reveals truly innovative solutions. External inputs (research, customer feedback) between iterations can further enhance ideas.
For creative thinking, we can make use of 4 thought patterns: causal chain, analogy, change of perspective and emotional association.
