Syllabus: OCR - A and AS Level Business
Module: Introduction to Business
Lesson: External Growth

Introduction

External growth, or inorganic growth, is a key topic within the OCR A and AS Level Business specification. It sits within Unit 1: “Business Objectives and Strategy” and directly supports learners in understanding how businesses expand beyond internal means. Whether through mergers, takeovers or strategic alliances, this topic helps students grasp not only how businesses scale but also the implications of such decisions on stakeholders, risk, and market positioning.

This article is designed to support teachers, SLT, and careers leads by unpacking the curriculum alignment, offering practical teaching insight, and exploring how the topic bridges into the real world of business and future employability.

Key Concepts

According to the OCR A Level Business specification, students should be able to:

• Define external growth and distinguish it from organic growth.

• Describe and evaluate different forms of external growth, including mergers and takeovers.

• Understand the motivations behind external growth strategies, such as:

  • Economies of scale

  • Increased market share

  • Access to new markets or technology

  • Elimination of competition

• Assess the risks and challenges associated with external growth, including:

  • Integration issues

  • Cultural clashes

  • Diseconomies of scale

• Evaluate the impact of external growth on stakeholders (shareholders, employees, customers, etc.).

OCR also expects students to build arguments using economic reasoning and business logic, interpret financial implications, and connect decisions to long-term strategic aims.

Real-World Relevance

External growth is regularly in the headlines, making it a rich source of up-to-date classroom examples. Consider:

• Amazon’s acquisition of MGM for $8.45 billion (2021) as a vertical integration strategy to expand streaming content.

• Sainsbury’s attempted merger with Asda, which was blocked by the CMA in 2019 due to competition concerns—a great discussion starter for evaluating the risks of external growth.

• Microsoft’s acquisition of Activision Blizzard, the biggest deal in gaming history, showcases not only scale but also the regulatory scrutiny such deals attract.

These examples bring abstract concepts to life, supporting students in developing commercial awareness and connecting learning to live business events.

How It’s Assessed

OCR assesses this topic across both AS and A Level papers using a range of question types:

• Short-answer questions: Definitions or brief applications (e.g., “Define external growth”).

• Data response questions: Based on case study materials, students may be asked to analyse why a business might pursue a takeover.

• Extended evaluative essays: For example, “Evaluate the benefits and risks of a merger strategy for a growing business.”

Command words are essential:

• Explain – describe and support with examples.

• Analyse – present logical chains of reasoning.

• Evaluate – weigh up arguments and make justified judgements.

Students should be encouraged to use business terminology precisely, and apply contextual knowledge, not just recall facts.

Enterprise Skills Integration

This topic provides a perfect opportunity to develop real-world enterprise skills:

• Decision-making: Learners can debate whether a merger is the right strategic move, using financial data and stakeholder perspectives.

• Problem-solving: Case-based dilemmas (e.g., cultural conflicts post-merger) help students think critically.

• Team collaboration: Group tasks simulating M&A negotiations allow students to explore competing interests.

Enterprise Skills’ Business Simulations can be embedded here—letting students experience external growth decisions in real time through facilitated scenarios. They choose whether to acquire a rival, what risks to accept, and how to pitch that choice to stakeholders.

Careers Links

External growth is highly relevant to career pathways in:

• Corporate finance and M&A advisory (investment banking, strategy consulting)

• Business development roles (analysing acquisition opportunities)

• Project management (integration of acquired firms)

• Legal and compliance roles (regulatory approval processes)

This directly supports Gatsby Benchmarks 5 and 6, giving students “encounters with employers” and simulated “experiences of the workplace” through role-play and problem-solving tasks.

Teaching Notes

Tips for delivery:

• Use recent, high-profile mergers or takeovers to kick-start discussion.

• Encourage students to take stakeholder roles and argue different perspectives.

• Use flowcharts and visual aids to break down stages of a merger.

Common pitfalls:

• Students often conflate external and internal growth—reinforce definitions early.

• Many miss the nuance of why a business might reject external growth (e.g., risk aversion, culture).

Extension activity:
Run a mock acquisition scenario using Enterprise Skills’ Business Simulations format. Split the class into ‘buyer’, ‘target firm’, and ‘stakeholders’. Let students negotiate terms, present to a board, and reflect on outcomes.

Time-saving support:
Enterprise Skills’ Skills Hub includes plug-and-play slide decks, case studies, and discussion templates tailored to this topic. No need to start from scratch.
