Moving Up the Value Chain

Enterprise Growth Strategies — Porter’s value chain, primary and support activities, and the six requirements for managing it

What is a Value Chain?

Value chain
The whole series of activities that create and build value at every step. The total value delivered by the company is the sum total of value built up throughout the company. In simple words, a value chain is a high-level model of how businesses receive raw materials, add value through processes, and sell finished products to customers.

Relatable example

For a chai brand, the chain runs from buying tea leaves (inbound), to brewing and packing (operations), to delivering packets to shops (outbound), to advertising (marketing and sales), to answering customer queries (services) — with purchasing, technology, people and finance supporting every step.

Where the idea comes from

Michael Porter developed the concept (the textbook cites his book ‘Competitive Advantage’ — 1980 in one passage and 1985 in another). ‘Value chain’ analysis looks at every step from raw materials to end users to deliver maximum value. Porter suggested that activities within an organisation add value to the service and products produced, and that all activities should run optimally for competitive advantage. If run efficiently, the value obtained should exceed costs — leading customers to return.

Porter’s Generic Value Chain — Primary and Support Activities

Porter split organization activities into ‘primary activities’ and ‘support activities’.

Porter’s generic value chain — tap any activity

Primary activities flow from left to right — tap any activity for its detail.

Support activities

Margin: run efficiently, value obtained exceeds cost — customers return.

Tap any activity to see what it does. Primary activities run the chain; support activities underpin them; the margin is what is left when value exceeds cost.

These primary activities are the core activities involved in creating and delivering the product/service; the support activities assist the primary activities in achieving competitive advantage.

Any one — or a combination — of these activities is essential for a firm to develop the ‘competitive advantage’ Porter discusses.

Margin idea: run efficiently, the value obtained exceeds the cost — customers return. (Shown as a margin band on the right of the chain.)

Six Requirements for Value Chain Management

The manager’s job

Value chain managers constantly seek ways to improve processes. The key requirements:
1

Coordination and Collaboration — essential for efficiency, avoiding duplicated efforts and achieving common goals by working together.

2

Technology Investment — crucial for manufacturing and distribution efficiency; outdated technology weakens competitiveness.

3

Organizational Process — identifying every aspect of the process and improving it through better technology and procedural knowledge.

4

Leadership — strong leaders are crucial for success, earning respect through sound practices, conflict management, motivation and direction.

5

Employee/Human Resources — a central hub for information and support on benefits, policies, hiring and conflict management; HR acts as a liaison and ensures employees have a voice.

6

Organizational Culture and Attitudes — fostering a strong cultural identity and positive attitudes attracts and retains top employees, boosting productivity.

Key Takeaways

Key Takeaways

  • A value chain is the whole series of activities that create and build value at every step — raw materials in, value added through processes, finished products out to customers.
  • Porter: all activities should run optimally for competitive advantage; value obtained should exceed cost so customers return (the margin idea).
  • Five primary activities: inbound logistics, operations, outbound logistics, marketing and sales, services — operations is where value is added.
  • Four support activities: procurement, technological development, human resource management, firm infrastructure.
  • Support activities assist primary activities; any one or a combination of them is essential for competitive advantage. (So what? — even one weak step, like slow delivery, can bleed the value the whole chain created.)
  • Six requirements for value chain management: coordination and collaboration, technology investment, organizational process, leadership, employee/HR, and organizational culture and attitudes.
