Post 1: How to Map Your Supply Chain and Identify Risks

Mapping your supply chain is the critical first step in identifying vulnerabilities. Without visibility, risks remain hidden until they disrupt your operations. In this guide, we’ll show you how to:

• Build a comprehensive map of your supply chain.
• Categorize risks by severity and likelihood.
• Collect data that helps you make proactive decisions.

Step 1: Start with Tier-1 Suppliers

Your tier-1 suppliers—those you directly work with—are the foundation of your supply chain map.

How to Do It:

1. List Your Suppliers:
   • Create a list of all your direct suppliers, including key details like location, product/service provided, and contact information.
   • Use tools like Excel, Google Sheets, or Airtable to track this data.
2. Track Dependencies:
   • Highlight which products or services rely on each supplier.
   • Mark critical dependencies (e.g., unique components or high-volume orders).
   • Practical Tip: Start with the suppliers that are most critical to your operations and build from there.

Example: Supplier List

Supplier Name	Location	Product/Service	Dependency (High/Low)	Contact Info	Notes
ABC Logistics	Shanghai, China	Freight Forwarder	High	email@abc.com	Key for Asia region
XYZ Packaging	Berlin, Germany	Packaging	Low	contact@xyz.com	Backup supplier

Step 2: Map Beyond Tier-1 Suppliers

Disruptions often come from sub-tier suppliers—those your tier-1 suppliers rely on. Mapping these layers uncovers hidden risks, such as over-reliance on a single region or supplier.

How to Do It:

1. Collaborate with Key Suppliers:
   • Open a conversation with your tier-1 suppliers to gather details about their upstream dependencies.
   • Example: If a raw material supplier relies heavily on one source in a region prone to natural disasters, that’s a critical risk.
   • Practical Tip: Create a simple questionnaire or checklist to make it easy for your suppliers to share this information.
2. Examine Historical Data:
   • Review past orders, delays, and supplier communication to identify patterns of risk.
   • Practical Tip: Use your purchase records to spot trends, such as bottlenecks tied to specific sub-tier suppliers.
3. Create a Tiered Map:
   • Visualize how your supply chain layers interact. Focus on identifying:
     • Tier-1 Suppliers: Direct partners who deliver goods/services to you.
     • Tier-2 Suppliers: The upstream suppliers your tier-1 vendors rely on.
     • Tier-3 Suppliers: Deeper dependencies, often tied to raw materials.
   • Tools: Use free or accessible platforms like Google Drawings, Lucidchart (free plan), or even PowerPoint to build your map.

Example: Tiered Map Structure

• Your Company
  • ↓ Tier-1 Supplier: Freight Forwarder A
    • ↓ Tier-2 Supplier: Customs Broker X
      • ↓ Tier-3 Supplier: Raw Material Provider Y (in a high-risk region)

• Practical Tip: Add color-coded risks (e.g., red for high-risk suppliers) to make vulnerabilities clear.

Example: Tiered Supply Chain Map

Visual Tip: Highlight Tier-2 suppliers that represent single points of failure. Use arrows to show how materials and components flow between nodes.

Step 3: Categorize Risks

Categorizing risks helps prioritize what to address first.

How to Do It:

1. Classify Risks by Type:
   • Internal Risks: Labor shortages, inefficiencies, outdated technology.
   • External Risks: Natural disasters, political instability, supplier insolvency.
2. Use a Simple Framework:
   • Create a table with columns for risk type, likelihood, and potential impact.
   • Include measurable indicators like “on-time delivery rate” or “supplier financial health.”
   • Practical Tip: Focus on the most obvious risks initially, then refine as you collect more data.

Example: Risk Categorization Table

Risk Type	Description	Likelihood	Impact	Key Indicator
Natural Disaster	Flooding in supplier’s region	High	High	Regional weather data
Supplier Failure	Financial instability	Medium	High	Supplier credit score

Step 4: Collect Supporting Data

Your map is only as good as the data behind it. Gathering detailed, accurate information ensures you’re working with actionable insights.

How to Do It:

1. Supplier Questionnaires:
   • Request critical details from your suppliers, such as:
     • Production capacity and lead times.
     • Sourcing practices and regional dependencies.
   • Example Question:
     • “What percentage of your raw materials comes from a single source?”
     • “Do you have contingency plans for regional disruptions?”
2. Performance Audits:
   • Review historical performance data for your suppliers, such as:
     • On-time delivery rates.
     • Frequency and resolution of defects or quality issues.
   • Practical Tip: Set up a simple scorecard in Excel to track supplier performance metrics over time.
3. External Data Sources:
   • Leverage publicly available resources to identify external risks like natural disasters or political instability.
   • Free Resources to Consider:
     • USGS Earthquake Hazards Program: For real-time updates on geological risks.
     • UN Comtrade Database: For global trade and export data.
     • Government or NGO Websites: Many governments provide free risk assessments for regions prone to disasters or conflict.
     • Weather Platforms: Use free weather apps (e.g., AccuWeather) to track disruptions near key supplier regions.
   • Practical Tip: Bookmark these sources for routine checks or subscribe to free alerts where available.

Example: Supplier Questionnaire

• What percentage of your materials is sourced from a single supplier?
• What is your average lead time for [specific product]?
• Do you have contingency plans for supply disruptions? If yes, please provide details.
• Can you share information about your tier-2 suppliers?

Tip: Use Google Forms or Typeform to collect responses easily.

Step 5: Create a Visual Supply Chain Map

A visual map makes it easier to understand the complexities of your supply chain, pinpoint vulnerabilities, and communicate risks across teams.

How to Do It:

1. Define Your Scope:
   • Focus on the sections of your supply chain that are most critical to your operations or pose the highest risk.
   • Example: Start with high-value suppliers, single-source suppliers, or those located in high-risk regions.
2. Create a Simple Framework:
   • Use a blank canvas, spreadsheet, or flowchart format to outline your supply chain structure.
   • Include key elements like:
     • Supplier locations (e.g., Tier-1, Tier-2).
     • Product flows (e.g., which suppliers provide which products or components).
     • Risk categories (e.g., regions prone to natural disasters or political instability).
3. Visualize Relationships:
   • Draw connections between suppliers, products, and processes.
   • Use color codes to highlight risks:
     • Red: High-risk suppliers or locations (e.g., single-source dependencies).
     • Yellow: Medium-risk suppliers (e.g., suppliers with recent performance issues).
     • Green: Low-risk suppliers or regions.
4. Add Key Annotations:
   • Include critical details such as:
     • Lead times for each supplier.
     • Contact information for supplier management teams.
     • Risk mitigation measures already in place (e.g., backup suppliers).
5. Regularly Review and Update:
   • Supply chains are dynamic and evolve over time. Set a schedule to update your map every quarter or after major events (e.g., onboarding a new supplier or experiencing a disruption).
   • Assign ownership to a specific team or individual to keep the map current.
