Value Chain Analysis — Primary and Support Activities

## Value Chain Analysis (Michael Porter)

Value Chain Analysis is a tool to examine the activities that create value within an organisation, helping to:

  • Identify sources of competitive advantage
  • Improve operational efficiency
  • Pinpoint areas for value enhancement

It divides all organisational activities into Primary Activities and Support Activities, which are intertwined — support activities enable and enhance primary activities.

### Primary Activities (5 Main Areas)

These directly contribute to creating and delivering the product/service to the customer.

#ActivityDescriptionExamples

2OperationsTransforming inputs into the final product/serviceMachining, packaging, assembly, testing
3Outbound LogisticsCollecting, storing, and distributing products to customersWarehousing, transport; or bringing customers to fixed-location services
4Marketing & SalesMaking consumers aware and enabling purchaseAdvertising, selling, sales administration, channel management
5ServiceEnhancing or maintaining product/service value after saleInstallation, repair, training, spare parts

> Memory aid: I O O M S — Inbound, Operations, Outbound, Marketing & Sales, Service

### Support Activities

Support activities underpin the primary activities across the entire chain. Key support activities include:

  • Firm Infrastructure (planning, finance, quality management)
  • Human Resource Management (recruitment, training, retention)
  • Technology Development (R&D, automation, IT systems)
  • Procurement (sourcing inputs for all activities)

---

### Key Principle

> Primary and Support activities are intertwined — a weakness in any support activity (e.g., poor HR) degrades all primary activities it underpins.

Worked example

### Example 1

Q: Explain the primary activities under Value Chain Analysis.

Michael Porter identified five primary activities:

1. Inbound Logistics: Activities related to receiving, storing, and distributing inputs to the product or service. Includes materials handling, stock control, and transport from suppliers.

2. Operations: Activities that transform inputs into the final product or service. Examples: machining, packaging, assembly, and testing on a production line.

3. Outbound Logistics: Activities that collect, store, and distribute products to customers. For physical goods: warehousing and transportation. For fixed-location services (e.g., a sports event): arrangements that bring customers to the service.

4. Marketing & Sales: Activities that make consumers aware of and able to purchase the product. Includes advertising, selling, sales administration, and distribution channel management. In public services, communication networks helping users access a service are important here.

5. Service: Activities that enhance or maintain the value of a product/service after it reaches the customer. Examples: installation, repair services, training, and supply of spare parts.

Agreement with statement: Yes — primary and support activities are intertwined. Support activities (HR, technology, procurement, infrastructure) run across all primary activities, enabling them to function effectively.

### Example 2

Scenario: Reshuffle Corp — Office Furniture Differentiation Using Value Chain Thinking

Context: Reshuffle Corp faces competition from online retailers offering similar furniture at lower prices.

Value-chain-based differentiation strategies:

Value Chain ActivityDifferentiation Opportunity
OperationsUse high-quality materials and innovative designs (tangible product superiority)
Outbound Logistics / ServiceOffer free installation or extended warranties (value-added intangible benefit)
Marketing & SalesBuild strong brand reputation for reliability and durability; emphasise customer service
ServiceAfter-sales support — repair, maintenance, customisation services
Technology Development (Support)Continual product feature optimisation based on customer feedback and market trends

Key insight: Reshuffle Corp should keep products at the centre of all strategic activities and manage the Product Life Cycle proactively — introducing new lines or upgrading existing ones as customer preferences evolve.

⚠️ Common exam mistakes

  • Listing only four primary activities and omitting 'Service' (the 5th) — Service is a distinct primary activity, not part of Marketing & Sales.
  • Treating Support activities as less important or optional — they are equally critical; the question often explicitly asks to confirm they are 'intertwined' with primary activities.
  • Reversing Inbound and Outbound Logistics: Inbound = receiving inputs FROM suppliers; Outbound = delivering finished output TO customers.
  • Forgetting the note about fixed-location services in Outbound Logistics — for services like events, outbound logistics means bringing customers TO the location, not delivering a physical product.
