5S: the disciplines underneath the photographs

Sorting is a decision about somebody else's belongings

The first stage looks trivial and turns political immediately. The half-used fixture, the spare motor, the trolley of parts kept back in case a customer reorders, the personal tool a setter bought himself: each has an owner and a story. Tagging items and moving them to a holding area works only if two things are settled beforehand, namely who may authorise disposal and how long something sits before it goes. Without that authority the holding area becomes a second store. Expect to find things nobody can explain, and expect at least one item to be reclaimed angrily, which is why the rules are agreed in advance.

Setting in order is workstation design, not labelling

The common error is to label the current arrangement, which fixes a bad layout in place with attractive signage. Positions should follow how the job is actually done: what is used every cycle sits within reach without turning, what is used at changeover sits close to the machine, what is used rarely can live further away. That means watching the work first and drawing shadow boards afterwards. Involve the person who does the job, because reach and height are personal and the arrangement designed by an engineer standing up at a bench is not the one a shorter operator can use through a full shift.

Cleaning treated as inspection rather than housekeeping

Wiping a machine down has one serious purpose: it puts a pair of hands on surfaces where leaks, loose fasteners, chafed cables, damaged guards and abnormal heat can be found before they become breakdowns. That changes what you ask for. Operators need to know what an abnormal condition looks like, need somewhere to record it, and need to see something happen afterwards. If findings pile up unresolved, reporting stops within weeks and cleaning reverts to appearance. The link with maintenance ownership is the point at which this stage stops being cosmetic and starts protecting availability.

A standard that survives a shift handover

Standardising means the same area looks and works the same way whoever is on shift, and that identical cells are arranged identically so an operator moved between them is not relearning. It requires a written and photographed reference, and a short routine that fits inside a shift rather than a monthly deep clean. The audit belongs to the line, not to a staff department: a supervisor walking with an operator and asking what is getting in the way produces more than a scored checklist filled in by a visitor. Scoring invites gaming, and gaming is easy to spot when scores rise and incidents do not fall.

Signals that the programme has become theatre

Watch for cleaning that intensifies before a visit, floor markings around equipment that nobody uses, spotless machines with the same recurring faults, and boards showing rising scores while operators still walk to a cupboard for a common tool. A genuine result shows up elsewhere: fewer minor stoppages caused by clutter and missing items, quicker changeovers because tooling is where it should be, fewer near misses from obstructed walkways, and new starters finding what they need without asking. Safety and access are the strongest arguments for keeping it going when production pressure rises, because those obligations do not pause for a busy month.

Frequently asked questions

Is 5S worth doing before anything else, or is it a distraction?

It is useful early because it is visible, cheap and teaches a team to change their own area, and because searching for tools and materials is a genuine drain on changeover and cycle time. It becomes a distraction when it turns into the whole programme, which happens in plants where the improvement effort never progresses past tidying. Treat it as groundwork that makes abnormal conditions easier to see, then move on to flow and problem solving.

Who should audit the area, and how often?

The area supervisor should look every shift as part of normal walking about, and someone from outside the area should walk it at a regular interval that is announced rather than sprung. The purpose of the outside walk is to see what has become invisible to the people living with it, not to award marks. Keep the record short, focus the conversation on obstacles the team cannot fix alone, and escalate those obstacles rather than logging the same finding repeatedly.

Our operators say tidying is not their job. How should a supervisor respond?

Take the objection seriously, because it usually means the time is not in the shift or the work is being added on top of a full production target. Two things settle it: put the routine inside the working pattern rather than at the end of it, and make sure what people report gets fixed. When cleaning is presented as inspection that prevents breakdowns and injuries rather than as appearance, and when the first reported leak is repaired quickly, resistance tends to fall away.
