The Challenge

Adhesive (Gum) preparation is the "silent driver" of quality in corrugation. Variability in mixing ratios and temperatures across different shifts led to inconsistent bonding, resulting in significant rework and wasted raw materials.

The Strategic Intervention

Instead of traditional classroom training, we implemented Performance Support in the Flow of Work. We digitized the "Tribal Knowledge" of the most senior operators into a standardized, scientific procedure.

Microlearning SOPs Sized under 120 seconds, these simulations focused on the 5 critical stages of gum mixing, accessible via tablets mounted at the station.
QR-Enabled Access QR codes were printed directly on adhesive barrels, ensuring that even a new hire on the night shift had the "expert view" instantly.
Behavior-Based Safety (BBS) Integrated safety checks for chemical handling into the mixing steps, making safety a part of productivity, not an extra task.

Measurable Evidence

Our post-intervention audits showed a clear correlation between microlearning access and defect reduction. The following index demonstrates the trend from baseline (100) to quarter-end stability.

Frequently Asked Questions

How did the shopfloor operators respond to QR codes?

Initial skepticism was replaced by enthusiasm when operators realized the QR codes acted as a "safety net." They no longer had to wait for a supervisor to verify mixing ratios, which gave them more autonomy and confidence.

What was the biggest technical challenge?

Environment readiness. In a manufacturing setting with dust and chemicals, we had to use ruggedized tablet mounts and high-durability laminated QR stickers to ensure the technology remained accessible.

Can this model scale to other processes?

Absolutely. We later scaled this to QC machine calibration and electrical maintenance. The principle of "Microlearning at Point of Need" is universal across manufacturing.
