Porter's Value Chain

⛓️

📖 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:

Chaîne de valeur : modèle qui décompose l'entreprise en activités clés pour comprendre où la valeur est créée.

🔍 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:

📋 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:

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:

Example (Operations linked to other activities):

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:

Example (Outbound Logistics with distributors):

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:

Example (Procurement activity):

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:

Example (Service activity at a car manufacturer):

🏢 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?

❷ Horizontal Links (with other activities):

❸ Vertical Links (with other companies):

❹ Impact on Costs:

❺ Value Creation:
