How a GPU warranty line nearly doubled output in seven quarters.
Over seven quarters, a global electronics manufacturer’s GPU warranty output climbed from 1,300 units per week to 2,571: 1,271 more units every week.
It wasn’t a one-time step change. Four capabilities stacked on top of one another, each working on the higher base the one before it had built.

The Line Was Leaving Output Behind
The warranty line was producing 1,300 units per week, and every added unit carries warranty revenue.
Filling seats alone wouldn’t move that number. On high-value GPU work, output depends on who is on the line, how well they’re trained, and when and how the work flows.
Where output was being lost:
Baseline output of 1,300 units per week- No weekend production segment
- Overnight test stopped at 2:30am
- A 7am/5pm mass start created startup downtime
Four Capabilities, Compounded
No single lever does this. Identify the right people, Amplify them through training, then Coordinate the floor — shifts and line flow — so the same, better team produces more.
Identifying Talent
18,246 applicants entered the funnel and 402 started. Array measured will, a proxy for desire to learn, to screen out poor fits before they cost a placement, then tracked productivity and fit after start to keep tuning who it sources.
Training
A structured warranty and rework program: general onboarding, an upgrade and advancement track, and a dedicated test-process curriculum. It was the largest single lever in the engagement.
Shift Optimization
Array’s analytics prescribed three moves: a dedicated 33-associate weekend crew running Fri–Sun, overnight test kept running past 2:30am for a full extra cycle, and staggered starts to break the 7am/5pm mass start.
Line Reengineering
With the workforce staffed for fit, trained and on optimized shifts, Array re-engineered the production flow itself: the closing lever that carried the line to its full potential.

Operational Outcomes
- Output rose every quarter for seven straight quarters: 1,300 → 1,488 → 1,699 → 1,930 → 2,042 → 2,190 → 2,571
- Training was the single largest lever: +403 units per week
- A new weekend segment and a full extra overnight test cycle added production time
- Same plant, more output: the work itself was redesigned
What This Proves
This GPU warranty line demonstrates that:
Screening for fit lifts output before training starts
Structured training is the biggest single productivity lever
Shift and flow design unlock output a line is leaving behind
No single lever does this. Compounded: +97.8%.
