1. The True Cost Structure (What you’re already doing)
You’ve got the right base. Keep it simple but disciplined:
- Material
- Direct Labor
- Manufacturing Burden (overhead)
- Scrap / Yield Loss
- Warranty / Quality Cost
- SG&A
- Profit
Upgrade this slightly for credibility:
Group it like a pro would:
- Conversion Cost = Labor + Burden
- Quality Cost = Scrap + Warranty
- Business Cost = SG&A + Profit
2. Cost Drivers (What actually moves the number)
This is where most buyers fail.
A cost breakdown is static. Cost drivers are dynamic.
You need to identify:
- What variables drive each cost bucket
- What suppliers can and cannot control
Examples (automotive-relevant):
- Material → commodity index (copper, resin), thickness, yield
- Labor → geography, automation level, takt time
- Burden → utilization rate, plant loading, depreciation
- Scrap → process capability (Cpk), design complexity
- SG&A → scale of supplier, program complexity
Insight:
Two suppliers can show the same cost breakdown but have completely different cost drivers → this is where negotiation leverage lives.
3. Commercial Levers (How you actually get cost out)
This is the piece most organizations completely miss.
Once you understand structure + drivers, you can act.
Your levers:
Design Levers
- Reduce material weight / complexity
- Standardize components
- Improve manufacturability (DFM)
Volume & Scale Levers
- Consolidate suppliers
- Increase award size
- Improve forecast accuracy
Process Levers
- Tooling optimization
- Cycle time reduction
- Automation investment
Commercial / Negotiation Levers
- Payment terms (cash neutrality strategy)
- Index-based pricing (commodities)
- Open-book costing
- Long-term agreements
“If you’re only looking at cost breakdowns, you’re auditing the past.
If you understand cost drivers and commercial levers, you’re controlling the future.”
