The Midnight Shift That Unlocked 528 Tons/Day

Practical Insights
There’s a moment in many manufacturing transformations when the team celebrates a win only to discover the win has created a brand-new challenge.
That’s exactly what happened at a continuous chemicals site after an improvement journey with Chartwell. The increased output from the improvement shifted the bottleneck to the site loading team.
With an increase in capacity, the team found themselves with the challenge of moving the increased inventory to customers to generate new sales opportunities instead of having it sit idly by. The site team proposed solutions focused on capital investment to loading infrastructure and headcount increases, which are both expensive and long lead-time solutions.
This set the stage for an alternative solutions that was one of the most effective “small change, big impact” improvements of the entire program.
Understanding the opportunity hidden in the day-to-day rhythm
To find additional shipping capacity, the team dug in and looked at the full 24‑hour loading cycle. To build an understanding of the system, the team:
- Mapped the current loading processes and system
- Conducted extensive observations of the process directly in the field
- Spoke to the people involved in managing and executing the process to confirm our understanding
This included diving into how the physical loading process worked, the safety and quality controls, the tasks the loading team did throughout the shift and the inputs that triggered each sub-process from start to finish.
From this analysis, the Chartwell team discovered that every morning from 7:00am to noon, the loading team was fully ready to work with people, product, and the loading racks were all prepared.
But railcars weren’t yet on‑site. They typically arrived later, after being processed at another facility.
One of the key aspects of Chartwell’s approach, and reasons why we effectively improve operations, is to challenge assumptions and constraints. And that’s just what the team did.
- Do all loading tasks have to be done only once railcars are here or could some be prepared earlier?
- What would need to be true for our teams to be able to pull prep tasks outside the cycle? Would this cause negative impacts elsewhere?
- How soon could we trial this?
By asking these questions, the team discovered there was a timing mismatch between when the team had maximum readiness and when assets arrived.
The insight: prep earlier, load earlier
The pivotal question became: “If the team is ready at 7:00am, what would it take for the railcars to be ready too?”
The answer was a small, elegant shift in the sequence of work:
Begin preparing and staging railcars earlier, starting at midnight, so they’re ready for the morning loading window.
By bringing cars in earlier, completing checks overnight, and aligning movement with the natural cadence of the operation, the team created a clear, predictable path to load more each day.
A single adjustment in timing unlocked the capacity they already had.
Before the shift:
- Rail cars: 10–11 cars/day
After shifting the prep window:
- Up to 16 railcars/day
That equates to +528 tons/day of additional product shipped – a 60% increase in load capacity in 2 weeks without extra headcount or capital investment.
A powerful outcome: changing mindsets
The improvement itself was meaningful, but the shift in thinking has had a large impact on the client team.
Once the team saw what was possible through a small scheduling experiment, new ideas started to emerge organically:
- “What else can we adjust?”
- “Could we align loading with maintenance windows?”
- “Are there other idle periods we can convert into productive ones?”
One client team member, who became a key driver of the change, began actively scanning for similar opportunities. The question “What can we do?” became a habit, not an intervention.
That mindset is what sustains performance long after any single improvement.
A small shift. A big impact. And a lasting mindset.
This didn’t require capital investment or an increase to headcount.
It was the kind of elegant, practical solution that becomes possible when a team approaches operations with curiosity, clarity, and the willingness to rethink how things are done.
The site didn’t just increase loading capacity.
It discovered a repeatable way to unlock revenue opportunity.
Small changes. Big impact.
