Supply Chain Optimization

Supply Chain Optimization

Required Inputs

Execution Steps

Step 1: Supply Chain Maturity Assessment

Score across 8 dimensions on a 1-5 scale:

Overall Maturity = Average score. Prioritize dimensions with scores below 3.

Step 2: Network Design Analysis

Map the current supply chain network and evaluate:

Network Structure Assessment:

Network Cost Breakdown:

Network Optimization Levers:

1. Facility consolidation / rationalization
2. Geographic repositioning (nearshoring, reshoring)
3. Multi-echelon inventory repositioning
4. Transportation mode shifts
5. Channel-specific fulfillment strategies

Step 3: Inventory Optimization

ABC/XYZ Classification

Classify all SKUs on two dimensions:

ABC (Value):

• A: Top 80% of revenue (typically 15-20% of SKUs)
• B: Next 15% of revenue (typically 25-30% of SKUs)
• C: Bottom 5% of revenue (typically 50-60% of SKUs)

XYZ (Demand Variability — Coefficient of Variation):

• X: CV < 0.5 — Stable, predictable demand
• Y: CV 0.5-1.0 — Variable demand with trends/seasonality
• Z: CV > 1.0 — Highly erratic, unpredictable demand

Combined Matrix — Inventory Strategy:

Safety Stock Calculation

For each SKU segment:

Safety Stock = Z-score x sqrt(LT x Demand_Variance + Demand_Avg^2 x LT_Variance)

Where:
  Z-score = Service level factor (95% = 1.65, 97% = 1.88, 99% = 2.33)
  LT = Average lead time (in periods)
  Demand_Variance = Variance of demand per period
  Demand_Avg = Average demand per period
  LT_Variance = Variance of lead time (in periods)

EOQ with Total Cost

EOQ = sqrt(2 x D x S / H)

Where:
  D = Annual demand (units)
  S = Fixed ordering cost per order ($)
  H = Annual holding cost per unit ($) = Unit cost x Carrying cost %

Total Annual Inventory Cost = (D/Q x S) + (Q/2 x H) + (Safety Stock x H)

Calculate optimal inventory investment and compare to current state.

Step 4: Demand Planning & S&OP Assessment

Demand Planning Effectiveness:

S&OP Process Maturity:

Step 5: Supply Chain Risk Assessment

Evaluate risk across 5 categories:

Risk Score Interpretation:

• 20-25: Critical — Immediate action required; executive visibility
• 12-19: High — Mitigation plan within 30 days
• 6-11: Medium — Monitor quarterly; contingency plan in place
• 1-5: Low — Annual review

Step 6: Total Cost of Ownership (TCO) Analysis

Calculate TCO for each major supply chain node / sourcing option:

Step 7: Develop Optimization Recommendations

For each recommendation, specify:

1. Description of the change
2. Affected nodes in the supply chain
3. Expected benefit ($ and service level impact)
4. Investment required
5. Implementation timeline
6. Risk and dependencies
7. ROI / payback period

Categorize recommendations:

• Quick wins (0-6 months): Parameter tuning, policy changes, contract renegotiation
• Medium-term (6-18 months): Network changes, system implementations, process redesign
• Strategic (18+ months): New facilities, major technology, structural network changes

Quality Checks

• All supply chain nodes in scope are assessed — no gaps between supplier and end customer
• Inventory optimization includes both value (ABC) and variability (XYZ) dimensions
• Safety stock calculations use actual lead time variability, not just average lead time
• TCO analysis includes hidden costs (quality, risk, inventory carrying) beyond unit price
• Risk assessment covers all 5 categories with specific mitigation actions
• Network cost breakdown sums to total and percentages reconcile to revenue
• Service level impact is stated for every recommendation — no savings without trade-off transparency
• S&OP assessment evaluates process maturity, not just whether meetings happen
• Recommendations are sequenced with dependencies identified
