🔗 Value Chain Analysis
Definition: A framework for identifying the specific activities a firm performs to create value and examining how each activity contributes to competitive advantage. Every link in the chain is a potential source of differentiation or cost advantage.
Developed by: Michael Porter (HBS), “Competitive Advantage” (1985)

🎯 How to Use Value Chain Analysis
Finding Sources of Competitive Advantage
Step 1: Identify all activities in your value chain
Step 2: Assess cost and value contribution of each activity
Step 3: Look for where you’re differentiated vs. competitors
Step 4: Identify which activities to invest in, outsource, or eliminate
Cost Analysis
- Where do we spend disproportionately?
- Can we reduce costs in non-strategic activities?
- What activities are commodity (outsource)?
Differentiation Analysis
- Where do customers see unique value?
- What activities drive quality, speed, innovation?
- Where is our moat created?

The value chain is the firm’s internal view. The Value System zooms out to include:
Supplier's → Your Firm's → Channel's → Buyer's
Value Chain Value Chain Value Chain Value Chain
Competitive advantage comes from linkages between value chains too (e.g., JIT with suppliers, EDI with retailers).
