Reflective Analysis of the Internal Business Environment
Porter’s Value Chain Model Applied to Tesco UK
Introduction
Understanding how a business creates value internally is essential for evaluating its competitiveness and long-term success. One of the most widely used frameworks for this purpose is Porter’s Value Chain Model, introduced by Michael Porter in 1985. This model breaks down a business into key activities that collectively contribute to value creation and cost efficiency.
This essay explores Porter’s Value Chain Model and applies it to Tesco, one of the largest and most familiar supermarket chains operating in the UK. It critically analyses Tesco’s internal business environment through both primary and supporting activities. The essay then reflects on how useful the model is in understanding real business operations.
Porter’s Value Chain Model
Michael Porter’s Value Chain Model was developed to help businesses identify how they create value and achieve competitive advantage. The model divides a company’s activities into two broad categories: primary activities and support activities. The idea is that each activity contributes either directly or indirectly to value creation, and improving these activities can increase profitability.
Primary activities are directly involved in the production and delivery of goods or services. These include inbound logistics, operations, outbound logistics, marketing and sales, and service. Inbound logistics focuses on receiving, storing, and managing inputs such as raw materials. Operations transform these inputs into final products or services. Outbound logistics deals with distributing the final product to customers. Marketing and sales focus on attracting customers and encouraging purchases. Service refers to after-sales support that maintains product value and customer satisfaction.
Support activities are not directly involved in production but help improve the efficiency of primary activities. These include firm infrastructure, human resource management, technology development, and procurement. Firm infrastructure covers organisational structure, planning, finance, and management systems. Human resource management focuses on recruitment, training, and employee development. Technology development includes innovation, automation, and systems that improve efficiency. Procurement involves sourcing the best inputs at the best possible cost.
The strength of the Value Chain Model lies in its ability to break down complex business operations into manageable parts. It helps managers identify inefficiencies, reduce costs, and improve value creation. It also highlights that competitive advantage does not come from one activity alone but from how all activities work together.
However, the model also has limitations. It was originally designed for manufacturing firms and may not fully reflect modern service-based or digital businesses. In today’s economy, where data, platforms, and customer experience play a major role, some value creation activities are less visible and harder to categorise.
Despite this, Porter’s Value Chain remains a useful analytical tool for understanding how internal business processes contribute to overall performance.
Overview of Tesco UK
Tesco is one of the largest supermarket chains in the UK and a leading global retailer. It operates thousands of stores across the country, ranging from large superstores to smaller convenience outlets. Tesco also runs a strong online grocery delivery service, which has grown significantly due to changes in consumer behaviour.
The company’s core business model is based on selling a wide range of food and non-food products at competitive prices while maintaining strong customer loyalty. Tesco serves millions of customers daily and focuses heavily on convenience, affordability, and product variety.
One of Tesco’s key strengths is its strong supply chain network. It works with thousands of suppliers globally to ensure consistent product availability. Tesco also invests heavily in technology and data analytics to understand customer preferences and improve stock management.
In recent years, Tesco has expanded its digital presence through online shopping platforms and mobile applications. This shift has allowed the company to compete more effectively with other retailers such as Sainsbury’s and Asda, as well as online competitors like Amazon.
Tesco’s internal business environment is complex, involving logistics, procurement, store operations, customer service, and digital systems. Because of this complexity, Porter’s Value Chain Model is particularly useful for analysing how Tesco creates value and maintains efficiency across its operations.
