Multi-Plant Standardization: Lessons From a National Converter

This converter operates 12 plants across the United States, all flexible packaging. Each plant had grown its own mounting room workflow over years. When new leadership decided to standardize, the project was significantly harder than they expected.

The problem with twelve different ways

The plants had wildly different storage solutions, different inventory tracking methods, different damage rates, and different changeover times. Best-performing plants had three times the throughput per mounter of the worst-performing plants.

Customers shipping the same product across multiple plants saw quality and lead time variation that was hurting strategic accounts.

The pilot

We started with two plants — one high-performing and one struggling. The goal was not to make them identical immediately, but to find the common operational platform that both could adopt without breaking what was already working.

The pilot took four months. Output: a documented standard for mounting room layout, storage equipment, inventory tracking, cart configurations, and workflow procedures.

The rollout

Plants were converted in pairs over 18 months. Each conversion was a 2-week onsite project with operator training and physical install. Total project: 9 pairs over 18 months, with the converter's internal team handling project management.

The results

• Cross-plant changeover variance dropped from 60% to 12%.
• Average damage cost per plant dropped 65%.
• Shared inventory between plants became viable for the first time.
• New hires could be trained in any plant and transition to any other plant without retraining.

The lesson

Standardization is only worth doing if you commit to it across the whole organization. Halfway standardization gives you the integration headaches without the integration benefits.
