Excess Setup Time & Changeover Waste
Definition
Result [2] identifies 'Changeover Time' as a key inefficiency (two Kaizen bursts aimed at 'reducing Changeover Time for Spot Welding'). Result [3] highlights 'high machine setup time' as a core constraint. Manual load sequencing often produces schedules that alternate between product types (e.g., RHS → SHS → Angle → RHS), maximizing changeovers. Optimized sequencing groups similar jobs (Batch-Push approach shown in [2]) to reduce setup frequency.
Key Findings
- Financial Impact: AUD 8,000–20,000 annually per fabrication line (estimated 5–8% of direct labor cost: typical shop pays AUD 50–65/hour loaded labor × 40–50 hours/week excess changeover = AUD 2,000–3,250/month × 12 months = AUD 24K–39K gross; net avoidable after optimization ~20–30% = AUD 5K–12K).
- Frequency: Daily (multiple changeovers per production shift)
- Root Cause: Reactive scheduling without job family batching; lack of integrated MRP system to group similar jobs for minimum changeover transitions.
