Reading: Michel Greif, “The Visual Factory”

Michel Greif, a French operations consultant who spent the 1980s studying Renault, Sony, Volkswagen, and Matsushita at close quarters, published L’Usine s’affiche in 1989; Productivity Press translated it into English as The Visual Factory in 1991. The book is a quiet, heavily illustrated argument that the discipline most contemporary Western managers had imported from Japan as 5S was, in fact, the visible surface of something larger — a complete operating philosophy in which what one sees on the floor of a factory is a more reliable guide to the health of the operation than any of the reports written about it.

Greif’s central distinction is between result-oriented and process-oriented management, and the book’s clearest statement of it is the passage the practice has returned to most often:

> The problem of recognition of production has seldom been approached properly… One error has been the orientation of indications of recognition towards results rather than towards processes that allow results to be obtained.

The argument is not the obvious one — that processes matter and results are downstream of them — but the operational consequence of believing it: a firm that wants its operators to develop the discipline that produces good results has to recognise the discipline itself, not only the results it produces. The recognition has to be specific, public, and visible on the floor where the work happens.

The book’s most-cited example, and the one the practice has carried into client conversations:

> In another example, Imai tells how servers in the cafeteria at a Matsushita plant formed a quality circle to investigate tea consumption during midday meals. By applying precise statistical methods, carefully recording each table’s consumption, and subsequently distributing teapots judiciously, they reduced tea purchases by nearly one-third. The presidential medal — the most distinguished of the firm’s awards — recognised the originality of these efforts in an unusual context. The result of saving a few tea leaves is meaningful only as it reveals the servers’ improvement-oriented methodology.

The medal was awarded for a few hundred dollars of tea leaves. The point is not the saving; the point is that a major Japanese industrial firm publicly recognised the practice of process-improvement thinking applied to a domain — cafeteria service — outside any reasonable definition of the firm’s strategic priorities. That is what Greif means by process orientation: the firm cares about the cast of mind, not the size of the prize.

Three of the book’s operational consequences travel directly into contemporary Lean practice.

Visual management is not signage. Most Western firms that have adopted 5S and visual-workplace practices have stopped at the boundary of decoration: colour-coded floor tape, labelled tool shadow boards, a status whiteboard at the end of the line. Greif’s argument is that the visual element is incomplete unless what is on the wall changes the work — unless the operator can act on what they see, in the moment, without escalation. A status board that no one reads on Monday morning is not visual management; it is a poster.

Recognition has to be specific to the discipline. The Matsushita medal could have been a productivity award, a savings award, or a department-of-the-year award; instead it was for the originality of the methodology. The practice’s experience is that this kind of specificity in recognition is harder to design than it sounds, and almost no Western firm gets it right on the first attempt.

The reports are downstream. Greif’s process orientation does not abolish results reporting; it inverts the priority between the reports and the floor. The figures on Monday morning describe what the floor did the previous week. They are the consequence of how the floor was organised and managed, not the input to it. Firms that try to manage by inverting this — running the floor from the figures — usually have the figures and almost never the floor.

The Visual Factory is thirty-five years old. Its illustrations look dated, its examples are predominantly Japanese, and the 5S discipline it elaborates is now standard practice on most reputable Western shop floors. The argument underneath the discipline, however, is harder to find than the discipline itself, and the book remains the place to find it stated most plainly.
