YH Employee of the Year | 100% Inventory Accuracy! He Never Stands in the Spotlight, Yet He Is the Brand's Strongest "Hole Card" in After-Sales Support

At 8:30 a.m., as the warehouse roller shutter had just been raised, Yuan Wang was already standing at the entrance of the lithium battery designated zone.

This was his first warehouse inspection of the day. On the shelves, roller brushes, filters, mainboards, and batteries were arranged in neat order, like a formation awaiting inspection. He reached out to touch the edge of a carton to confirm there were no signs of moisture damage; then he bent down to check the stacking height of the batteries to ensure it did not exceed the limit.

He repeats these actions countless times every day. To outsiders, this may seem almost obsessive, but for him, this is simply the daily routine of a warehouse supervisor—nipping problems in the bud before they ever occur.

This year marks his fifth year in this warehouse. His track record speaks for itself: 100% inventory accuracy, zero incidents for multiple consecutive years, and same-day clearance of all work orders even during peak periods.

He is Yuan Wang , YH's Employee of the Year. Today, we step onto his "battlefield" to witness the dedication and wisdom of a warehouse supervisor.

PART 01: The Accuracy Imperative

"Ship one wrong spare part, and you may lose a customer."

The robotic vacuum cleaner spare parts warehouse manages thousands of SKUs. Roller brushes, filters, mainboards, batteries... accessories with nearly identical appearances abound. A single mispick directly impacts the end user's repair turnaround time and, in turn, damages the brand client's after-sales reputation.

Yuan Wang's "uncomplicated approach" is as follows: every outbound shipment must undergo secondary verification; high-risk accessories such as batteries require independent re-inspection; inventory discrepancies must be identified, investigated, and closed out on the same day, with absolutely nothing carried over to the next day.

Beyond this, he implemented a cycle counting system: high-frequency spare parts are spot-checked weekly, while low-frequency items are counted monthly. "If it moves, it gets checked"—during picking and outbound operations, the remaining inventory at each location is simultaneously verified.

This combination of "uncomplicated methods and smart techniques" has enabled inventory accuracy to be maintained stably at 100%.

PART 02: Efficiency Challenges

"Peak periods are not meant to be endured; they are meant to be prepared for."

The work order rhythm of the spare parts warehouse fluctuates dramatically, with order volumes potentially doubling during major promotional events. Yuan Wang's approach is to prepare three steps ahead.

"Step one: engage with the client in advance to forecast after-sales work orders, and pre-position high-frequency repair parts in the shipping buffer zone. Step two: deploy flexible staffing for picking, verification, and packing positions, with forklift operators and system clerks working in staggered shifts. Step three: complete a round of cycle counting before the peak period to clear inventory discrepancies, preventing material shortages from being discovered only when volumes surge."

He also applied strategic thinking to slotting layout: using ABC classification, high-frequency spare parts such as roller brushes and filters are placed in "prime locations" closest to the verification and packing area, while low-frequency items are stored deeper in the warehouse. Pick lists are printed in location sequence to minimize back-and-forth travel. This adjustment improved individual picking efficiency by approximately 10%.

During a previous major promotional event, after-sales work orders surged, and the picking and verification stations became congested. Wang Yuan immediately restructured the operational zones on-site and opened an "express lane for urgent orders," clearing all work orders for the day. Subsequently, he codified a peak-period operations SOP, ensuring that similar volume surges have run smoothly ever since.

PART 03: Security challenges

"When it comes to lithium batteries, there is no room for even the slightest compromise."

The greatest safety risk in the spare parts warehouse comes from lithium batteries. Storage, packing, labeling—an error in any single step carries compliance risks. Yuan Wang's approach is: designated zone storage, daily inspections, and a closed-loop three-way reconciliation of documents, physical inventory, and the client system.

He insists on a "one-minute safety reminder" at every morning meeting, using real cases to reinforce battery stacking standards and forklift aisle safety protocols. During one inspection, he discovered an employee had stacked a carton of lithium batteries beyond the height limit and immediately intervened, preventing a potential safety hazard caused by battery compression. Afterward, he organized a full-team review, established a "red-line standard" for battery stacking height, and conducted a new round of all-staff training to strengthen the safety defense line.

"Safety is not a slogan hung on the wall; it is the execution of every action, by every person, every single day." This rigorous management has enabled his warehouse to achieve zero incidents for multiple consecutive years.

Closing Remarks

At the end of the interview, when asked "What sustains your consistent rigor and passion?" Yuan Wang 's answer was simple and honest: "Every spare part we ship directly affects the end user's repair turnaround time. As a 3PL service provider, the warehouse's accuracy and timeliness directly represent the brand client's after-sales reputation. This sense of responsibility drives me to never let my guard down."

He says that seeing mispicks and omissions continue to decline while efficiency steadily improves—that sense of "improvement achievement"—is the source of his work passion. And the moment that gives him the greatest sense of fulfillment is watching every shipment depart accurately, intact, and on time to destinations across the country: "We may not have direct contact with consumers, but every repair part shipped on schedule helps users get their devices fixed as quickly as possible. We are the brand's most reliable logistical support in after-sales service."
