The external environment

Introduction to the External Environment

Hi there! Welcome to one of the most important parts of your Business studies. Think of a business like a ship at sea. The "Internal Environment" is everything happening inside the ship (the crew, the engine, the cargo). But the External Environment? That is the ocean and the weather. The captain can't control the storm or the tide, but they must understand them to keep the ship on course!

In this chapter, we will explore the factors outside a business's control that can make the difference between huge profits and closing down. Let’s dive in!

1. Market Conditions: The Playing Field

Market conditions describe the current situation of the "playing field" where businesses compete. Two major things define this:

Degree of Competition

This is simply the number of businesses trying to sell the same thing to the same customers. Example: If you open a coffee shop on a street with ten other coffee shops, the "degree of competition" is very high.

• High Competition: Usually leads to lower prices for customers and lower profit margins for businesses because they have to fight for every sale.
• Low Competition: Businesses have more power to set higher prices and may enjoy higher profits.

Barriers to Entry

These are the "walls" that make it difficult for new businesses to join a market. Don't worry if this seems tricky at first—just think of it as "how hard is it to start this business?"

• High Barriers: It is very expensive or legally difficult to start (e.g., starting an airline requires millions of dollars for planes and licenses).
• Low Barriers: Anyone can start easily (e.g., a dog-walking service or an online blog).

Quick Review: High competition and low barriers usually mean a tougher environment for a business to stay profitable.

2. Measuring the Market (The Math Part)

To make good decisions, managers need to look at the numbers. Here are the three main ways we measure a market:

Market Size

This is the total value (money) or volume (number of items) of sales in a whole market. Example: The global market size for smartphones might be $500 billion a year.

Market Growth or Decline

Is the market getting bigger or smaller? We calculate this as a percentage change:

\( \text{Market Growth (\%)} = \frac{\text{New Size} - \text{Old Size}}{\text{Old Size}} \times 100 \)

Concentration Ratio

This tells us how much "power" the biggest companies have. It is the percentage of the total market held by the top few firms (usually the top 3 or 5). Example: If the top 3 supermarket chains have 80% of all sales, the concentration ratio is very high. This means a few big "players" dominate the game.

Key Takeaway: Managers prefer growing markets because there are more customers to win without necessarily stealing them from competitors.

3. External Factors: The "Big Six"

The syllabus highlights six specific external changes that can affect a business's costs, demand, and profits. Let's look at each:

1. Incomes

When people earn more money, their disposable income (money left after taxes and bills) goes up. Result: Demand for "luxury" goods (like holidays or designer clothes) usually rises. However, demand for "budget" brands might actually fall because people can now afford better!

2. Interest Rates

This is the cost of borrowing money or the reward for saving. The Logic: If interest rates go up, people with mortgages have less money to spend, and it becomes more expensive for a business to take out a loan to expand.

3. Exchange Rates

This is the price of one currency in terms of another. It affects any business that buys from or sells to other countries.

Memory Aid: SPICED
Strong Pound (or currency) Imports Cheap, Exports Dear (Expensive).
Translation: If your country's currency is strong, it's cheaper to buy materials from abroad, but harder to sell your products to foreign customers because they find your prices too high.

4. Costs of Inputs

Inputs are the things a business needs to make its products (raw materials, electricity, rent). Result: If the price of oil or electricity goes up, the cost of production rises, which usually leads to lower profits unless the business raises its own prices.

5. Government Policies

Governments can change the rules at any time! Examples: Increasing the minimum wage (raises costs), changing taxes (affects profits), or introducing new environmental laws.

6. Competition from Abroad

In a global world, a local business isn't just competing with the shop next door; it's competing with websites and factories across the globe. Result: This often forces local businesses to become more efficient to keep their prices low enough to compete.

Did you know? Many businesses use a tool called PEST analysis to track these changes, though your syllabus focuses specifically on the six factors listed above!

Common Mistakes to Avoid

• Confusion over Interest Rates: Don't forget that interest rates affect both the business (cost of loans) and the customer (money available to spend).
• Ignoring the "Why": In an exam, don't just say "interest rates rose." Explain that "interest rates rose, therefore consumers have less disposable income, which means demand for the business's luxury products will likely fall."
• Mixing up Market Size and Market Share: Market size is the whole pie; market share is the slice one specific company owns.

Summary: The "Big Picture"

The External Environment is constantly changing. Successful businesses are proactive—they try to predict these changes and adapt their strategy and tactics before the "storm" hits. Whether it is a change in government policy or a rise in interest rates, the goal is always to minimize risk and protect profits.
