📖 What is the Value Chain?
The Value Chain is a model created by Michael Porter that breaks down a company into its key activities to understand where value is created.
Key idea: A company creates value by performing a series of activities that transform inputs (materials, labor) into outputs (products or services) that customers are willing to pay for.
Purpose: By analyzing each activity, companies can:
- Identify sources of competitive advantage
- Find ways to add more value for customers
- Discover opportunities to reduce costs
- Understand which activities are most important
Chaîne de valeur : modèle qui décompose l'entreprise en activités clés pour comprendre où la valeur est créée.
🔗 Structure of the Value Chain
The value chain consists of two types of activities:
SUPPORT ACTIVITIES (Secondary Activities)
🏢 Firm Infrastructure (Management, Finance, Planning)
👥 Human Resource Management (Recruiting, Training, Compensation)
💻 Technology Development (R&D, Process Improvement, Innovation)
🛒 Procurement (Purchasing, Supplier Management)

🔍 How to Analyze the Value Chain
💡 Important Principle:
Value chain analysis must go beyond simple description of activities. You must analyze the potential contribution of each activity to creating or strengthening competitive advantages, mainly through:
- Value creation: How does this activity add value that customers appreciate?
- Cost reduction: How can this activity help reduce costs?
📋 The Five Key Questions for Each Activity
For each activity in the value chain, you should ask and answer these five questions deeply and rigorously:
1 What does this activity consist of?
QUESTION: What does this activity consist of in the case of the company?
En quoi consiste cette activité dans le cas de l'entreprise?
What to analyze:
- Describe precisely what the company does in this activity
- What are the specific tasks and processes?
- What resources (people, equipment, technology) are used?
- How is this activity organized?
Example (Inbound Logistics at a clothing manufacturer):
"We receive fabric from 15 suppliers in Asia and Europe. Materials are inspected upon arrival, then stored in our 5,000m² warehouse. We use a computerized inventory system to track all materials. Average storage time is 2 weeks before production."
2 Horizontal Links
QUESTION: What relationships exist between this activity and other links in the company's value chain?
Quelles relations y a-t-il entre cette activité et les autres maillons de la chaîne de valeur?
What to analyze:
- How does this activity connect to other primary activities?
- How does it connect to support activities?
- What information or materials flow between activities?
- How do changes in one activity affect others?
Example (Operations linked to other activities):
- Link to Inbound Logistics: Production schedule determines when materials are needed
- Link to Marketing: Customer orders influence production priorities
- Link to HR Management: Need for trained workers affects production quality
- Link to Technology: New machines improve production efficiency
3 Vertical Links
QUESTION: What relationships exist between this activity and those performed by other companies?
Quelles relations y a-t-il entre cette activité et celles réalisées par d'autres entreprises?
What to analyze:
- Links with suppliers (upstream in the value system)
- Links with distributors and retailers (downstream in the value system)
- How do supplier activities affect our activities?
- How do our activities affect customer/distributor activities?
- Opportunities for collaboration or coordination
Example (Outbound Logistics with distributors):
- We coordinate delivery schedules with retail partners to ensure shelves are stocked
- Retailers share sales data so we can adjust production volumes
- We provide packaging that makes products easy for retailers to display
4 Impact on Costs
QUESTION: What impact do this activity and its links have on the company's costs?
Quel impact ont cette activité et ses liens sur les coûts de l'entreprise?
What to analyze:
- What are the direct costs of this activity?
- What are the indirect costs (overhead)?
- How do links with other activities affect total costs?
- Where are the main cost drivers (factors that increase costs)?
- Opportunities to reduce costs
Example (Procurement activity):
- Direct costs: Purchasing department salaries = $200,000/year
- Impact on other costs: Better supplier negotiations reduced material costs by 8%
- Link impact: Working with fewer suppliers reduced transaction costs by 15%
- Cost driver: Number of suppliers and complexity of contracts
5 Value Creation
QUESTION: How can this activity and its links bring value?
Comment cette activité et ses liens peuvent-ils apporter de la valeur?
What to analyze:
- How does this activity make the product/service more valuable to customers?
- What features, benefits, or experiences does it create?
- How do links enhance value creation?
- Can this activity create differentiation or competitive advantage?
- Opportunities to increase customer willingness to pay
Example (Service activity at a car manufacturer):
- 24/7 roadside assistance increases customer peace of mind → higher perceived value
- Free maintenance for 3 years differentiates us from competitors
- Link with Technology: Mobile app for service booking makes it convenient
- Link with Marketing: Excellent service creates word-of-mouth recommendations
- Value: Customers willing to pay 5% premium for better service experience
🏢 MOROCCAN EXAMPLE: Marjane (Retail Chain)
Value Chain Analysis: Marjane Supermarket
Let's analyze the "Procurement" support activity using the five questions:
❶ What does this activity consist of?
- Procurement team negotiates with thousands of suppliers (local and international)
- Purchases food products, household goods, electronics, clothing
- Develops partnerships with local Moroccan producers for fresh products
- Uses centralized purchasing system for all stores nationwide
- Manages supplier contracts and payment terms
❷ Horizontal Links (with other activities):
- Link with Inbound Logistics: Purchasing decisions affect delivery schedules and warehouse space needed
- Link with Operations: Product selection affects shelf space planning and store layout
- Link with Marketing: Procurement negotiates promotional pricing for sales campaigns
- Link with Technology: IT systems track inventory levels and automatically trigger reorders
- Link with Finance: Payment terms with suppliers affect cash flow
❸ Vertical Links (with other companies):
- Upstream (suppliers):
- Works closely with dairy farms in Fes region for fresh milk supply
- Coordinates with vegetable growers in Souss-Massa for seasonal produce
- Partners with international brands (Nestlé, Danone) for exclusive product launches
- Impact on suppliers: Large order volumes help suppliers achieve economies of scale
- Benefit from suppliers: Suppliers invest in better packaging and quality for Marjane's standards
❹ Impact on Costs:
- Direct costs: Procurement staff salaries, travel for supplier visits, contract management systems
- Cost reduction impact: Bulk purchasing power reduces cost per unit by 15-25%
- Negotiated payment terms: 60-90 day payment periods improve Marjane's cash flow
- Centralized purchasing: Saves costs compared to each store negotiating separately
- Local sourcing: Reduces transportation costs and import duties
❺ Value Creation:
- Product variety: Wide selection from many suppliers = more choice for customers
- Fresh local products: Partnerships with Moroccan farmers = fresher produce = happier customers
- Competitive pricing: Strong negotiation power = lower prices passed to customers
- Exclusive products: Some brands available only at Marjane = differentiation
- Quality assurance: Strict supplier standards = reliable product quality
- Result: Customers perceive Marjane as offering good value for money
🎯 Key Takeaways from Value Chain Analysis:
- Not just description: Analysis must go deep to find competitive advantage opportunities
- Activities are interconnected: Understanding links is crucial for optimization
- Two paths to advantage: Add value (customers pay more) OR reduce costs (higher margins)
- External links matter: Coordination with suppliers and distributors can create value
- Question everything: Each activity should be examined for improvement potential
