Prioritising warehouse improvements: impact versus effort

The manager is holding a list: a new rack, setting up balances in 1C, replacing labels, redrawing the receiving area, changing the shift schedule, surveillance cameras. Thirty ideas, and the strength for three a month. Which to start with? Often the choice falls on whatever was said loudest or caused the most pain recently. An impact and effort matrix moves this choice from chance towards calculation, and it can be done in three simple steps.

Step one: gather the list

Sources: staff ("what gets in your way?"), customer complaints, results of audits and stock counts, last month's errors, the manager's own observations. Write each idea in one sentence, showing exactly what will change: "stick location labels on the racks" is a good entry, "improve order" is a bad one. An idea that is not written precisely cannot be assessed. Do not keep the list open too long: gather it in a week or two and close it. An endless list adds not change but mental load. Let staff leave an idea in an easy way: write it in a shared chat or drop a note in a box in the warehouse.

Step two: scoring on two axes

Each idea gets two scores from 1 to 5: impact and effort. Impact is measured by how much money it saves, how much time it cuts and how many errors it removes. Turn it into money where you can: hours saved × the cost of an hour, fewer errors × the price of one error. Effort is measured by cost, time, the number of people involved and their resistance. Assess effort together with the person who will do the work, because from the outside a job always looks easier. For example (illustrative), if errors in receiving cost 12 hours of correction a month and an hour costs 25,000 so'm, tidying the receiving log saves 300,000 so'm a month. That is not a score but an exact figure, easy to compare with other ideas.

Step three: four boxes

• high impact, low effort: quick wins. Do these first;
• high impact, high effort: big projects. They need a separate plan, an owner and a deadline;
• low impact, low effort: small conveniences. Do them in spare time or give them to one person;
• low impact, high effort: distractions. Decline them and strike them off the list.

The matrix guards against two risks. The first is putting off quick wins and jumping straight to a big project, which takes long and shows results late. The second is busying yourself with small things that take much time but change nothing important. Sometimes ideas depend on each other: location-based storage does not work without location labels. Assess such pairs together.

An example

An example, with illustrative scores (impact/effort). Location labels on racks: 4/2, a quick win. Receiving log in Excel: 3/1, a quick win. Full move to location-based storage: 5/4, a big project. A fully automated system: 4/5, a big project, but not before the process is stable. Buying a new rack: 3/5, a distraction for now, because you first need to see whether the existing space is used properly. A new table in the receiving area: 2/1, a small convenience. The result: this month two quick wins, by the end of the quarter one big project, and the rest in the queue. The manager has chosen three ideas out of thirty and can explain to staff why exactly those. When staff know why their idea was chosen or put off, they are readier to suggest another.

Rhythm and discipline

Update the matrix every quarter. Do not start more than three initiatives at once, because people's strength is limited: when there is too much to do, everything is slow and half-finished. Close completed work with a result: did the expected impact really appear? If the impact came out lower than expected, do not hide it; correct the way you score. This makes later scoring more accurate. There is one more useful habit: keep a "stop list", that is, write down what you have decided not to do. Then the same subject will not come up again every month. Mandatory tasks, for example safety requirements or a customer's conditions, are done outside the matrix; they cannot be chosen.

Conclusion

Resources are always fewer than ideas, so what matters is not doing a lot but doing the right thing. The OmborExpert specialists assess warehouse processes and help rank improvements by priority and draw up a quarterly plan.
