Changeover Opacity
The facility knew changeovers took 'about 2-3 hours' but didn't track actual duration, variance, or component steps. Changeover time was accepted as fixed overhead rather than an optimization opportunity.
What Became Visible
Detailed changeover tracking showed extreme variance: fastest changeover (experienced team) took 1.2 hours; slowest took 4.8 hours on the same line for the same product variant. This 4x variance proved changeover duration was highly controllable—most variance came from process inconsistency, not inherent product complexity.
Changeover Standardization & Skill Transfer
The facility captured the fastest changeover methodology as a standard procedure, trained all teams to this standard, and implemented pre-changeover material staging to eliminate wait time.
How it worked: Real-time changeover analytics identified the fastest teams' approaches: parallel staging, pre-positioned tools, simplified verification steps. These methodologies were documented and systematically implemented across all shifts.
Results
vs previous 1.2-4.8 hours
per line
from changeover optimization
Changeover duration variance indicates methodology variance, not product complexity. When fastest methodology is visible, it becomes the template for all teams.
Operational Reality
This improvement required no new equipment or investment—just visibility into what the best teams were already doing, combined with systematic standardization.
