Custom AGV Drive Wheel Pilot-Run to Mass-Production Playbook

Custom AGV drive wheel projects usually fail during scale-up, not during sample stage. The sample runs, but process controls, quality gates, and supply stability are not mature enough for sustained batch delivery.

This playbook defines how to move from one successful sample to repeatable mass production.

Phase 1: Engineering Sample (Design Feasibility)

Target: verify core function and fit in real chassis constraints.

Key actions:

• Freeze functional requirements: load class, torque, speed band, protection level.
• Validate mounting envelope, cable routing, and thermal boundary.
• Record open risk list and required design corrections.

Exit criteria:

• Functional targets met in defined test conditions.
• Critical fit issues closed or assigned with dates.
• Pilot BOM baseline drafted.

Phase 2: Pilot Build (Process Learning)

Target: prove manufacturability and detect repeatability gaps.

Key actions:

• Produce pilot lot using fixed BOM and controlled process route.
• Capture defect data by station and root cause category.
• Measure assembly takt, rework ratio, and first-pass yield.

Pilot metrics to track:

Exit criteria:

• Pilot quality trend stabilizes against agreed threshold.
• Top defect causes have verified corrective actions.
• Process risks are quantified for qualification stage.

Phase 3: Process Qualification (Repeatability Proof)

Target: prove that output quality is stable across shifts, operators, and batches.

Key actions:

• Lock work instructions and torque standards.
• Validate inspection checkpoints and traceability records.
• Run consistency checks across operators/shifts.

Qualification package should include:

• Process flow and control points.
• Inspection plan and acceptance limits.
• Traceability method for critical parts.
• Change control and deviation escalation path.

Exit criteria:

• Qualified process documentation approved.
• Repeatability evidence accepted by buyer quality team.
• Release condition for SOP formally signed.

Phase 4: SOP Release (Supply Reliability)

Target: deliver stable volume with controlled lead time and quality variance.

Key actions:

• Define monthly capacity and ramp plan.
• Set safety stock policy for critical components.
• Activate post-launch monitoring dashboard.

SOP monitoring metrics:

Common Scale-Up Failures

1. Pilot corrections not converted into controlled work standards.
2. Component substitutes introduced without formal change control.
3. Traceability incomplete, making root-cause closure slow.
4. Capacity planning ignores critical component lead-time variability.

Any one of these can erase pilot gains during SOP ramp.

Buyer Checklist Before PO Release

Before issuing production PO, confirm:

• Pilot quality data is representative of production conditions.
• Known failure modes have permanent corrective actions.
• Process control plan and inspection criteria are documented.
• Change control responsibility is clear between teams.
• Spare and warranty response process is operational.

If these five conditions are not closed, PO risk remains high.

What to Send for a Faster Technical Review

To accelerate supplier-side program planning, share:

• Target timeline by milestone (sample, pilot, SOP).
• Pilot lot quantity and acceptance criteria.
• Annual demand forecast and mix assumptions.
• Destination market and compliance requirements.
• Required reporting format for quality and traceability.

This information directly improves execution predictability.

Bottom Line

A successful sample is not a supply system. A supply system requires repeatable process control, documented acceptance gates, and disciplined change management.
