“The number is ninety-nine point two,” Miller said.
“I see the number,” I said.
“It is a good number,” Miller said.
“It is a bad number,” I said.
Miller looked at the paper. Miller looked at the graph. The graph showed a line. The line was flat. The line stayed near the top of the page. The page represented the month of . In , the vans were on the road. The vans were not in the shop. The vans did not have flat tires. The vans did not have broken engines. The system recorded the status of every van. The system said the vans were available.
I looked at the clock. It was . I knew where the vans were. The vans were at the job sites. The vans were parked in driveways. The vans were parked on the street. I knew what the drivers were doing. The drivers were not working. The drivers were looking for parts. The drivers were looking for tools. The drivers were moving boxes to find other boxes.
The gap between “Available to the System” and “Useful to the Job.”
The Multiplication of Inefficiency
“We have forty vans,” I said.
“We have forty vans,” Miller said.
“Every driver loses twenty minutes a day,” I said.
“Twenty minutes is not a long time,” Miller said.
“Twenty minutes is a long time when you multiply it,” I said.
I took a pencil. I wrote on the paper. I wrote the number forty. I wrote the number twenty. I multiplied the numbers. The result was eight hundred. Eight hundred minutes is thirteen hours. I wrote the number thirteen. We lost thirteen hours every day.
We lost thirteen hours because the vans were messy. The vans were disorganized. The vans were full of wooden shelves. The wooden shelves were broken. The wooden shelves were soft. The wooden shelves did not hold the tools in place.
The report did not see the thirteen hours. The report only saw the shop time. The report saw the time when a mechanic touched the van. A mechanic did not touch these vans. The vans ran well. The engines were strong. The tires were new. The vans were available to the system. The vans were useless to the job.
The White Van Illusion
I walked to the window. I saw a van in the lot. It was a Ford Transit. The van was white. The van had the company name on the side. The van looked perfect. If you looked at the van from the street, you would think the van was efficient. You would think the company was doing well. You would not see the inside. You would not see the piles of screws on the floor. You would not see the heavy drill sliding across the wood.
A fleet is a tool. A tool should work. A tool that wastes time is a broken tool. But the system does not count wasted time. The system only counts broken engines. We have optimized the fleet against the wrong metric. We have made the fleet excellent at staying out of the shop. We have not made the fleet excellent at doing the work.
The Friction of Four Minutes
I remember a driver named Hannes. Hannes was a good worker. Hannes was fast. Hannes became slow. I watched Hannes work. Hannes opened the back door of the van. Hannes looked for a junction box. The junction box was under a pile of cables. Hannes moved the cables. The cables were heavy. Hannes found the box. Hannes then looked for a screwdriver. The screwdriver was in a plastic bucket. The bucket was full of trash. Hannes spent four minutes looking. Hannes did this ten times a day.
Hannes did not report a problem. The van was not broken. The van started every morning. The van drove to the site. The fleet manager was happy with Hannes. The fleet manager saw that the van was on the road. But Hannes was losing his day. Hannes was tired. Hannes was frustrated by the mess.
The Plywood Tax
The mess is a cost. The mess is a tax on the day. We pay the tax every hour. We pay the tax because we use universal racks. We use racks that do not fit the van. We use racks made of plywood. Plywood is cheap to buy. Plywood is expensive to own. Plywood absorbs water. The rain comes in the door. The wood swells. The drawers stick. The driver pulls the drawer. The drawer does not open. The driver hits the drawer. The wood cracks. Now the drawer is always open. The tools fall out. The tools hit the floor. The tools get lost.
I told Miller about the wood. Miller said the wood was fine. Miller said we saved money on the wood. I told Miller we lost thirteen hours a day. I told Miller that thirteen hours is two workers. We are paying two people to look for wrenches. We are paying two people to move cables.

The Architecture of the Workspace
The solution is not more vans. The solution is better vans. We need a system that fits the van. Every van is different. A Fiat is not a Ford. A Volkswagen is not a Renault. The anchor points are in different places. The walls have different shapes. A universal rack leaves gaps. Gaps are where tools go to hide. Gaps are where the screws fall.
I looked at the designs from Tecnolam. The designs used steel. The steel was twenty-ten thickness. The steel was strong. The steel was cut for the specific van. There were no gaps. The racks bolted to the factory points. No holes were drilled in the floor. The steel did not swell. The steel did not crack. The drawers moved on rollers. The drawers stayed closed when the van moved. The drawers opened when the driver pulled the handle. This is a simple thing. A drawer should open. A drawer should close. When a drawer does not open, the fleet is failing.
We look at the 3D design before we buy. The design shows the shelves. The design shows the cabinets. We see the interior before the steel is cut. This is how you stop the loss. You plan the space. You do not just throw shelves into a box. You build a mobile workshop.
The Engineering of Certainty
If the work stops to find a tool, the workshop is broken. If the driver is kneeling on a wet floor to find a bolt, the workshop is broken. The report will say the van is available. The report is lying. The van is a storage unit that moves. It is not a workshop.
I think about the weight. Wood is heavy. Steel is light when it is engineered. The 20/10 steel sheet is thin but rigid. It has a polyester powder coating. The coating prevents rust. The rust is what kills the drawers. The rust makes the metal rough. The rough metal sticks. Then the driver hits the drawer again. The cycle repeats.
I told Miller we should change the racks. I told Miller we should buy the steel. Miller asked about the price. I showed him the thirteen hours. I showed him the eight hundred minutes. In one month, we lose two hundred and sixty hours. Two hundred and sixty hours is more than the cost of the steel. The steel pays for itself in weeks. The steel stops the search.
Excellence in the Wrong Direction
We are now excellent at the wrong thing. We are excellent at keeping old, slow vans on the road. We should be excellent at finishing the job. The job is why we have the vans. The van is not the product. The work is the product.
I stopped looking at the ninety-nine percent. I started looking at the minutes. I started looking at the hands of the drivers. Are the hands holding tools? Or are the hands moving junk? If the hands are moving junk, the fleet is down. It does not matter what the screen says. It does not matter if the engine is running. The engine can run all day, but if the wrench is lost, the invoice is not signed.
“A report can count a van that does not start, but a report cannot count a drawer that does not open.”
The Silent Upgrade
We changed the first five vans. We used the 3D designs. We used the model-specific fittings. The drivers did not complain. The drivers did not talk about the vans. This is how you know a tool is good. People stop talking about it. They just use it. The twenty minutes disappeared. The drivers came back early. They were less tired.
Miller still looks at the reports. The reports still say ninety-nine percent. Miller thinks nothing has changed. I know better. I know the thirteen hours are back. I know the forty vans are now working like forty-seven vans. We did not buy seven more vans. We just fixed the ones we had.
We stopped the drag. We looked at the floor of the van instead of the screen of the computer. The truth was on the floor. The truth was in the steel. We found the truth, and then we fixed the report by ignoring it.
