Most suggestion schemes collect a few ideas, implement fewer and quietly die. What makes an idea system work: small ideas, fast response, people implementing their own ideas, and leaders who treat ideas as a priority.
The suggestion box had been on the canteen wall for six years. It received a handful of ideas a year, most of them complaints, and responses took months. A new plant manager replaced it with a simple board in each area, a two-week response commitment and a rule that people should implement their own ideas where possible, with help. Within a year the plant was implementing more than a thousand ideas, most of them small: a better tool holder, a relabelled shelf, a changed sequence, a guard that no longer needed removing. Our idea system case study tells that story in detail.
The difference was not the people. It was the system.
Why traditional suggestion schemes fail
- They ask for big ideas, which are rare, slow to evaluate and often need capital.
- Responses are slow, so people stop submitting.
- Ideas are evaluated by managers, not implemented by the people who had them.
- Rewards are tied to calculated savings, which creates arguments and delays.
- Rejected ideas get no explanation.
Principles of an idea system that works
- Small ideas are welcome, in fact preferred. Most improvement comes from many small changes.
- Ideas are about the person's own work area, things they can see and influence.
- Response is fast: acknowledgement within days, decision within one or two weeks.
- The person who had the idea implements it where possible, with support.
- Ideas are visible on a board in the area, so everyone can see progress.
- Recognition is frequent and simple: thanks, visibility and celebration, rather than complex financial rewards.
A simple process
- An employee notices a problem or opportunity and records it on a simple card or form: the problem, the idea and the expected benefit.
- The team leader reviews it with them within a few days: approve, adapt or explain why not.
- Approved ideas are implemented by the employee, with help from maintenance or engineering where needed.
- Before-and-after results are recorded, often with a photo.
- Ideas are shared across teams, so good ideas spread.
The leader's role
The idea system lives or dies with front-line leaders. They need time, authority to approve small changes and support from managers for anything bigger. Senior leaders should review idea activity regularly, celebrate examples and remove obstacles. Asking about ideas during gemba walks is one of the most effective signals that ideas matter.
Measuring success
Useful measures include ideas submitted and implemented per person per year, average response time and the share of employees participating. Savings matter, but measuring participation and speed drives the right behaviour. Mature systems commonly see several implemented ideas per employee per year.
Linking ideas to bigger improvement
Small ideas build the habit of improvement. Larger opportunities identified through the idea system can become kaizen events or improvement projects. Over time, the idea system becomes the everyday foundation of the improvement culture.
