Execution Steps
Step 1: Supply Chain Maturity Assessment
Score across 8 dimensions on a 1-5 scale:
| Dimension | 1 - Reactive | 2 - Functional | 3 - Integrated | 4 - Collaborative | 5 - Orchestrated |
|---|---|---|---|---|---|
| Demand Planning | No forecasting; order-driven only | Basic statistical forecasting | Demand sensing with multiple inputs | Collaborative forecasting with customers | AI-driven demand shaping |
| Inventory Mgmt | No formal policy; gut-feel ordering | Reorder point / EOQ basics | ABC segmentation; safety stock calc | Multi-echelon optimization | Dynamic, demand-driven positioning |
| Sourcing | Single source; price-only decisions | Approved vendor lists; RFQ process | Category management; TCO analysis | Strategic partnerships; joint planning | Supplier ecosystem orchestration |
| Manufacturing | Build to stock; long runs | Basic scheduling; some flexibility | Pull-based; mixed-model capability | Demand-driven; postponement | Agile / mass customization |
| Logistics | Reactive shipping; no carrier mgmt | Rate shopping; basic TMS | Optimized routing; mode selection | Integrated logistics network | Autonomous / real-time optimization |
| Visibility | No end-to-end visibility | Visibility within functional silos | Cross-functional dashboards | Multi-tier supply chain visibility | Predictive / prescriptive analytics |
| Risk Management | No risk assessment | Basic risk register | Scenario planning; dual sourcing | Continuous monitoring; response plans | Predictive risk management |
| Sustainability | No sustainability focus | Compliance-driven only | Scope 1-2 emissions tracked | Full Scope 3 measurement; targets set | Circular supply chain; net-zero path |
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:
| Element | Current State | Benchmark / Best Practice | Gap |
|---|---|---|---|
| Number of suppliers (Tier 1) | |||
| Number of manufacturing sites | |||
| Number of distribution centers | |||
| Average distance to customer | |||
| Number of echelons | |||
| % single-sourced SKUs | |||
| Geographic concentration risk |
Network Cost Breakdown:
| Cost Category | Annual Cost ($) | % of Revenue | % of Total SC Cost | Benchmark |
|---|---|---|---|---|
| Raw materials / COGS | ||||
| Inbound freight | ||||
| Manufacturing / conversion | ||||
| Warehousing / DC operations | ||||
| Outbound freight | ||||
| Last-mile delivery | ||||
| Inventory carrying cost | ||||
| Customs / duties / tariffs | ||||
| Total Supply Chain Cost |
Network Optimization Levers:
- Facility consolidation / rationalization
- Geographic repositioning (nearshoring, reshoring)
- Multi-echelon inventory repositioning
- Transportation mode shifts
- 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:
| X (Stable) | Y (Variable) | Z (Erratic) | |
|---|---|---|---|
| A (High Value) | Lean flow; JIT; low safety stock | Demand-driven; moderate safety stock | Strategic buffer; vendor-managed |
| B (Medium Value) | Kanban; reorder point | Periodic review; seasonal build | Make-to-order where possible |
| C (Low Value) | Bulk order; maximize efficiency | Periodic review; accept stockouts | Eliminate or special-order only |
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:
| Metric | Current | Target | Gap |
|---|---|---|---|
| Forecast accuracy (MAPE) | < 20% (A items) | ||
| Forecast bias | < 5% | ||
| Forecast horizon | 12-18 months rolling | ||
| Forecast granularity | SKU x Location x Week | ||
| Demand sensing lag | < 1 week |
S&OP Process Maturity:
| Element | Current Practice | Target Practice |
|---|---|---|
| Meeting cadence | Monthly minimum | |
| Participants | Cross-functional: Sales, Ops, Finance, Supply Chain | |
| Planning horizon | 18-24 months rolling | |
| Scenario planning | 3 scenarios (base, upside, downside) | |
| Financial integration | P&L impact quantified for each scenario | |
| Decision authority | Clear escalation; executive sign-off | |
| KPI tracking | Forecast accuracy, plan adherence, bias |
Step 5: Supply Chain Risk Assessment
Evaluate risk across 5 categories:
| Risk Category | Risk Factor | Probability (1-5) | Impact (1-5) | Risk Score | Mitigation |
|---|---|---|---|---|---|
| Supplier | Single-source dependency | P x I | |||
| Supplier | Financial viability of key suppliers | ||||
| Supplier | Geographic concentration | ||||
| Operational | Capacity constraints | ||||
| Operational | Quality failures | ||||
| Logistics | Transportation disruption | ||||
| Logistics | Port / border congestion | ||||
| Demand | Demand volatility / bullwhip | ||||
| External | Geopolitical / trade policy | ||||
| External | Natural disaster / pandemic |
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:
| Cost Element | Current ($) | Alternative 1 ($) | Alternative 2 ($) |
|---|---|---|---|
| Acquisition Costs | |||
| Unit price / COGS | |||
| Freight / inbound logistics | |||
| Customs / duties / tariffs | |||
| Ownership Costs | |||
| Inventory carrying cost | |||
| Warehousing / handling | |||
| Quality / inspection costs | |||
| Operating Costs | |||
| Outbound logistics | |||
| Returns / reverse logistics | |||
| Stockout cost (lost sales) | |||
| Risk Costs | |||
| Supply disruption (expected value) | |||
| Currency / commodity hedging | |||
| Compliance / regulatory | |||
| Total Cost of Ownership | $[X] | $[X] | $[X] |
| TCO per unit |
Step 7: Develop Optimization Recommendations
For each recommendation, specify:
- Description of the change
- Affected nodes in the supply chain
- Expected benefit ($ and service level impact)
- Investment required
- Implementation timeline
- Risk and dependencies
- 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
