The factory was in Austria. Industrial production. A seasoned floor manager who had been running the operation for years and who looked at me with the specific wariness of a man who has seen consultants come and go without leaving anything useful behind.
“The last guy spent three months here,” the floor manager told me on day one. “Left us a 200-page report. We use it to prop open the storage room door.”
I told him I wasn’t planning to write a report. I was planning to watch.
For the first two weeks, I did nothing but observe. I stood on the factory floor with a notebook and a stopwatch. I timed every process. I documented every handoff. I mapped every movement of materials from one station to the next. I asked questions that sounded simple and revealed complexity: “Why do you carry that component to Station B before bringing it to Station C?” and “How do you decide which order gets processed first?”
By the end of week two, I had found the 40%.
Where the Time Was Hiding
The factory’s production processes were individually efficient. Each station — cutting, forming, finishing, assembly, quality check — operated at or near its designed capacity. If you measured any single station, it looked fast.
But the time between stations was catastrophic.
Components sat in buffer zones between stations for an average of forty-seven minutes per transition. In a process that involved five stations, that meant nearly four hours of waiting for every unit produced. The actual production time — the time a human or machine was working on the component — was about two hours. The transit and waiting time was roughly equal to the production time.
Nobody noticed because the buffer zones had always been there. They were part of the factory’s architecture, both physical and cultural. “That’s how it works” was the explanation, and after twenty-two years, the floor manager genuinely believed it was true.
The 40% savings came from redesigning the flow between stations, not the stations themselves. It was a systems problem, not a task problem. Every individual task was fine. The system connecting them was broken.
The Solution
Three changes, implemented over six weeks:
Change one: Physical reorganization. We moved Station C closer to Station B, reducing the transport distance by 60%. This required rearranging equipment that hadn’t been moved in a decade. The floor manager was skeptical. The forklift operator was annoyed. The result was a reduction in transit time between the two highest-volume stations from twelve minutes to four minutes per unit.
Change two: Batch size reduction. The factory processed in batches of fifty units. This made sense when setting up a station took thirty minutes — you wanted to minimize setups by running large batches. But setup times had been reduced by new equipment to about eight minutes. Nobody had adjusted the batch size. By reducing batches to fifteen units, we reduced buffer times dramatically because downstream stations received work sooner instead of waiting for the full batch of fifty to complete.
Change three: Pull-based scheduling. The factory ran on a push system — each station produced as fast as it could and pushed work downstream. When Station A was faster than Station B, work accumulated in the buffer. We switched to a pull system: Station B signaled when it was ready, and Station A produced accordingly. No more buffers. No more waiting. Continuous flow.
None of these changes involved new technology. No software. No automation in the robotic sense. No AI, no IoT sensors, no expensive equipment. Just a better arrangement of existing resources, based on observing where time was actually being lost rather than where the factory assumed it was being lost.
What the Floor Manager Taught Me
I arrived expecting to teach him about efficiency. He taught me about implementation.
On paper, the three changes were obvious. In practice, they required changing habits that forty people had built over years. The buffer zones weren’t just physical spaces — they were psychological comfort zones. Workers used the buffer time for breaks, conversations, and mental transitions between tasks. Removing the buffers felt, to them, like removing rest periods.
He explained this to me on week three. “Your plan works on paper. My people aren’t paper.”
He was right. And the implementation succeeded because we addressed the human factor alongside the process factor.
We introduced structured micro-breaks — five minutes every ninety minutes — that replaced the informal break time the buffers had provided. We involved the floor workers in the reorganization, asking for their input on equipment placement and flow patterns. We ran the new system alongside the old one for two weeks so people could experience the difference rather than being told about it.
The 40% time savings materialized gradually over six weeks rather than immediately. The full implementation took three months rather than the six weeks I’d estimated. The floor manager’s understanding of his team’s needs extended the timeline and improved the outcome.
This experience directly shaped the velocity principle I later developed. Speed isn’t about rushing. It’s about removing the things that slow you down. In this factory, the slowdown wasn’t in the production. It was in the spaces between production.
The Innovation Lesson
Innovation isn’t always technology. Sometimes the most impactful innovation is looking at an existing process with fresh eyes and asking: where is the time hiding?
This question applies to every business, not just factories:
Where are you waiting between stages of your sales process? The gap between a lead expressing interest and your first response might be your biggest conversion killer.
Where are your products sitting in buffer zones? The time between production and shipping, between writing and publishing, between designing and testing — each gap is potential value lost.
Where are you pushing when you should be pulling? Producing content, products, or services without signals from the demand side creates buffers of unsold inventory, unread content, and unused capacity.
The subtraction audit is the founder’s version of what I did on that factory floor. Stand back. Observe. Time everything. Find where the real time loss is hiding. Then fix the spaces between the work, not just the work itself.
The floor manager still runs that factory. The changes stuck because they were his changes, implemented with his team, refined by his knowledge of the people and the process. The consultant’s role was to see what familiarity had made invisible. The implementation was the floor manager’s.
The best innovations aren’t the ones the consultant brings in. They’re the ones that were always there, hidden in the spaces between the things everyone was already doing.
