The Spaghetti on Your Floor
The Gemba Roastery · Chapter 32 — // THE GOLDEN ZONE
Last chapter, we walked. This chapter, we draw.
The first lens of the Roastery Gemba audit is the physical flow — where things and people actually move, as opposed to where you think they move. And there's a reason it comes first: motion and transport are the wastes hiding in plain sight. Nobody logs them, no report captures them, and every one of them costs wages.
The tool for seeing them is fifty years old and needs nothing but a pencil: the spaghetti map.
Draw the spaghetti
Print your floor plan. Pick one operator. For ten minutes, draw a continuous line tracking everywhere they go — every trip to the scale, every walk to the green storage, every doubling-back for the tape gun that wasn't where it should be.
The result almost never looks like a workflow. It looks like a bowl of spaghetti — loops, crossings, backtracks. Every crossing line is a decision your layout forced. Every long stroke is transport; every short shuffle around a workstation is motion. None of it roasted a single bean.
The map works because it converts a feeling — "the floor seems busy" — into a picture you can act on. Busy is invisible. A red tangle on a floor plan is not. And beside that tangle you can draw the second line: the lean path, the route the work would take if the layout served it. The distance between the two lines is your opportunity.
Checkpoint 01 — The Golden Zone
☕ Are the most-used tools — sealer, scales, tape, bags — between waist and shoulder height?
The Golden Zone is the band between your waist and your shoulders. Inside it, the body works for free: no bend, no reach, no strain, no step. Outside it, every retrieval costs a movement — and on a production floor, movements repeat hundreds of times a shift.
Walk to your packing bench and look at what actually lives in the zone. In most roasteries, it's a mix of daily-use tools and things that landed there in 2023 and never left. Meanwhile the tape gun is on a low shelf, the spare bags are above head height, and the scale scoop migrates daily.
The fix is placement by frequency: what's used every batch lives in the zone; what's used weekly lives at its edges; what's used monthly lives off the bench entirely. This is the first move of workplace organisation, and it costs nothing but an honest hour.
Measure it this week: stand at the bench and count how many times in one packing run a hand leaves the Golden Zone. Fix it this week: relocate the top three offenders.
Checkpoint 02 — Travel distance
☕ How many steps does a staff member take to get a fresh pallet of green coffee, or a stack of empty bags?
Every step is unpaid transit time. It doesn't feel like waste because walking feels like working — but the customer doesn't pay for a single stride of it.
The arithmetic is brutal once you do it. Count the trips to green storage per shift. Multiply by the steps each way. A roastery making six trips a shift at forty steps each way has an operator walking nearly five hundred steps a day just fetching — a hidden commute inside your own building, on the clock, every day, forever.
Lean's answer is point-of-use storage: the materials live where the work happens. A day's green staged beside the roaster at the start of the shift. Bags and labels for today's run at the packing bench, not in the store room. The green store becomes a warehouse you visit once — not a destination you orbit all day.
Measure it this week: count one operator's fetch-trips for a single shift. Fix it this week: stage tomorrow's materials at the point of use before the shift starts, and count again.
Checkpoint 03 — The clutter check
☕ Is there dead inventory — old seasonal labels, broken grinders — taking up prime real estate on the production floor?
Floor space is not equal. The square metre beside the roaster is worth more to your operation than ten square metres in the back corner, because proximity to the work is what eliminates motion. Which makes it remarkable what we let squat there: the broken grinder awaiting a repair that will never come, the box of last winter's seasonal labels, the "useful someday" shelf.
Dead stock in the Golden Zone means live work is being done somewhere worse. Every obsolete object holding prime position pushes a daily-use tool one reach further away — and those reaches compound into the spaghetti you drew at the start of this chapter.
The clutter check is the simplest audit point of the nine: walk the floor and ask of every object within arm's reach of a workstation, "when was this last used?" If the answer is "last month" or "I don't know," it doesn't belong there. Red-tag it, relocate it, or bin it.
Measure it this week: count the objects in prime positions that haven't been touched in thirty days. Fix it this week: clear the worst workstation — just one — and watch what happens to the spaghetti around it.
The straight line
Run all three checkpoints and you've completed the first lens of the audit. You'll have a spaghetti map that shows the cost, and three fixes that shrink it — tools in the zone, materials at the point of use, dead stock evicted from prime ground.
The red tangle is what you have. The green line is what's possible. The distance between them is measured in steps, reaches, and minutes — and at the end of the year, in wages and margin.
Next chapter, the second lens: the machine interface — information gaps, decision fatigue, and the visible floor that ends both.
