33% Reduction in Customer Quality Complaints

The customer is a global leader in motion and control technologies, with a division specializing in fluid connectors and fittings for industrial and mobile applications. The division runs high-volume assembly cells that process up to 250 work orders and guides per day across multiple benches. At this throughput, even small inconsistencies in how operators execute a step can compound quickly into costly quality problems downstream.

As cell volume climbed, the manufacturer began seeing quality variation that traced back to how work was performed at the bench, rather than to the equipment or materials themselves. Each customer complaint carried a real cost: roughly $415 in administrative overhead per claim, on top of the damage to customer trust.

The manufacturer's first attempt at a fix leaned too far in the other direction. Old digital work instructions were long and click-heavy, asking operators to read and confirm nearly every line. That thoroughness produced a new problem: operators began clicking through validation checks without truly reading or performing them, treating required confirmations as a formality rather than a control.

Leadership had to reinforce, cell by cell, that signing off on a guide carried the same weight as physically checking a fitting's dimensions. If a step was marked required, it existed to stop a defective part from reaching a customer, not to slow the operator down.

The manufacturer needed a way to standardize critical checks across benches and shifts without burying operators in low-value clicks.

The goal was to keep guides lean enough to sustain high-volume output while making sure the checks that mattered most, critical dimensions and packaging rules, were never skipped or rubber-stamped.

The manufacturer implemented digital work instructions in Dozuki with required validation checks built directly into the shop floor workflow. Rather than keep every original step, the team ran several rounds of improvement to strip out clutter and non-essential clicks, narrowing guides down to the checks that actually protected quality: critical dimensions and packaging rules. Every remaining required step stayed in place and was reinforced as non-negotiable.

This was a deliberate trade-off. Early guides tried to capture everything and lost operator attention as a result. The refined version asked for less, but treated what remained as inviolable, holding operators accountable to a standardized process instead of a checklist they could click through on autopilot.
