A storeroom people can find things in

A storeroom works when a technician can find a part in under a minute and the system knows it went. Almost every problem in maintenance stores comes from one of those two failing, and they fail in a fixed order: first the location, then the record.

One fixed location per part

Every part has one place, that place is labelled, and the location is on the record. Parts stored wherever there was room cannot be found and cannot be counted, and no amount of software fixes it.

Label the shelf and the part

The label on the shelf tells you what belongs there, which is how you notice something is missing. The label on the part tells you what it is when it has been put back in the wrong place, which it will be.

Put the fast movers near the door

Not in part number order. The twenty items that account for most issues should be within a few steps of the entrance, and the once-a-year items can be at the back on a high shelf. This is obvious and almost never done, because storerooms get organised by catalogue rather than by use.

Decide who can take things, and make the alternative easy

Free access means the record is fiction. A locked storeroom with nobody available at seven in the morning means parts get taken anyway and nothing is recorded, which is worse.

The workable pattern is scan to issue: anybody can take a part at any hour, and taking it requires scanning the part and the job. Two seconds, no storeperson needed, and the record stays true.

Kit the scheduled work the day before

Parts picked into a box with the job number, ready in the morning. It is the single highest-return habit in a maintenance storeroom, because it converts several interruptions of skilled time into one hour of a storeperson’s.

Cycle count instead of an annual stocktake

A few items every week, weighted so the critical and fast-moving parts are counted several times a year and the slow ones once. Errors get found while they are small, and nobody has to shut the storeroom for two days.

Deal with the returns shelf

Every storeroom has a pile of parts that came back from jobs and were never put away. It grows, it is not in the count, and eventually somebody buys a part that was sitting in it. Empty it weekly, as a scheduled task with a name against it.
