Welcome to the External Environment!

In this chapter, we are stepping outside the "four walls" of a business. While managers can control what happens inside their office, they can't control the world outside. We call this the External Environment. It’s like a game of chess—you can control your pieces, but you have to react to the weather, the rules of the game, and what your opponent is doing!

Don't worry if some of these terms sound like they belong in a news report. We will break them down into simple, everyday ideas. By the end of these notes, you’ll understand how things like interest rates and new laws can make or break a business strategy.

1. The Competitive Environment: Porter’s Five Forces

Michael Porter came up with a famous way to look at how "intense" competition is in any industry. He identified five specific "forces" that determine how much profit a business can actually make.

What are the Five Forces?

1. Rivalry among existing competitors: How many other businesses are doing exactly what you do? If there are many, you’ll have to fight hard (often by lowering prices) to keep customers.

2. Bargaining power of buyers (customers): If you only have one big customer, they have all the power! They can demand lower prices. If you have millions of customers (like Netflix), they have less power individually.

3. Bargaining power of suppliers: If there is only one company that sells the raw materials you need, they can charge you whatever they want. This raises your costs.

4. Threat of new entrants: How easy is it for a new person to start a business in your industry? It’s easy to start a dog-walking business (low threat) but very hard to start an airline (high barriers to entry).

5. Threat of substitute products: This isn't just a different brand (e.g., Pepsi vs. Coke). It’s a different way of doing the same thing. For example, a "substitute" for a taxi is a rental bike or a bus.

Memory Aid: Use the mnemonic "B-S-R-N-S" (Bears Scare Really New Scouts) to remember: Buyer power, Supplier power, Rivalry, New entry, Substitutes.

How do businesses respond?

A business might try to influence these forces. For example, they might buy their supplier (to reduce supplier power) or create a "loyalty card" scheme to reduce buyer power by making customers stay.

Quick Review: If Porter’s forces are strong, the industry is less profitable because the business has less control over its prices and costs.

2. The Political and Legal Environment

Governments set the "rules of the game." These can be opportunities (like a new trade deal making it easier to sell abroad) or threats (like a new tax).

Key Areas of Law and Policy:

  • Trade Agreements: Rules between countries that make trading easier.
  • Protectionism: When a government tries to help its own country's businesses by adding Tariffs (taxes on imports) or Quotas (limits on the amount of goods coming in).
  • Consumer Protection: Laws that say products must be safe and "as described." This protects customers but adds costs for businesses to ensure quality.
  • Employee Protection: This includes The Equality Act, which prevents discrimination based on age, gender, race, etc. It ensures fair treatment in the workplace.
  • Competition Policy: Laws that stop businesses from ganging up to fix high prices.
  • Environmental Protection: Rules on pollution and waste.

Did you know? Protectionism is like a "home-field advantage." By making foreign goods more expensive with tariffs, the government hopes you’ll buy from local businesses instead.

Key Takeaway: When laws change, businesses must adapt their functional areas. For example, a new environmental law might require the Operations department to change how they package products.

3. The Economic Environment

The economy is like the "tide." When the tide is high (economic growth), most boats (businesses) rise. When it’s low, things get difficult.

The Big Economic Variables:

1. GDP (Economic Growth): This measures the total value of everything a country produces. High GDP = people have more money to spend.

2. Taxation: Direct taxes are on income/profit. Indirect taxes (like VAT) are on spending. Higher taxes usually mean less spending by customers.

3. Inflation: This is when prices rise. If inflation is high, a business's costs (like rent and raw materials) go up, and they may have to raise their own prices.

4. Interest Rates: The cost of borrowing money. If interest rates go up, it’s expensive for a business to take out a loan to expand. Customers also spend less because their mortgages/loans cost more.

5. Unemployment: If many people are out of work, demand for luxury goods falls. However, it might be easier and cheaper for a business to hire new staff.

Exchange Rates: The "SPICED" Trick

Exchange rates are the value of one currency against another. This is crucial for businesses that import or export.

SPICED stands for: Strong Pound, Imports Cheap, Exports Dear (expensive).

  • If the Pound gets stronger, it costs less to buy parts from abroad (good for Operations), but our products look expensive to foreigners (bad for Marketing).
  • WIDEC is the opposite: Weak Pound, Imports Dear, Exports Cheap.
Calculating the Effect:

If the exchange rate is \( £1 = \$1.20 \), an export priced at \( £100 \) will cost a US customer \( \$120 \).
If the Pound strengthens to \( £1 = \$1.50 \), that same \( £100 \) item now costs the customer \( \$150 \).
The result: Sales in the US will likely fall because the price increased for the customer.

Key Takeaway: Businesses respond to economic changes by changing prices, cutting costs, or moving to different markets where the economy is stronger.

4. The Social Environment

This is about people—their ages, what they believe in, and how they behave. Social trends change slowly but have a massive impact.

  • Demographic Factors: For example, the UK has an "ageing population." This is an opportunity for businesses selling healthcare or retirement travel, but a threat to businesses aimed at teenagers.
  • Consumer Values: People are becoming more concerned about ethics and the environment. If a business ignores this, their brand reputation could suffer.
  • Activism: This is when groups of people (often via social media) pressure a business to change its behavior (e.g., stopping the use of plastic straws).

Analogy: Social trends are like fashion. If a business keeps selling "flared trousers" when everyone is wearing "skinny jeans," they will eventually go out of business!

5. Technological Change

Technology can be disruptive. This means it doesn't just improve things; it completely changes how an industry works (think about how Netflix "disrupted" DVD rental shops).

  • Digital Technologies: Using the internet to sell, track data, or communicate.
  • Artificial Intelligence (AI): Using computers to do tasks that usually require human intelligence, like customer service chatbots or predicting what customers will buy next.

How businesses respond: They must invest in new tech to stay competitive. If they don't, a faster, more high-tech rival will take their customers. This impacts Finance (because tech is expensive) and HR (because staff need new training).

Quick Review: Summary of the External Environment

Porter’s Five Forces: Rivalry, Buyer Power, Supplier Power, New Entrants, Substitutes.

Political/Legal: Laws on equality, consumers, and trade (Tariffs/Quotas).

Economic: GDP, Interest Rates, Inflation, and Exchange Rates (SPICED).

Social: Demographics (age) and changing values (ethics).

Technological: Digital change and AI disrupting markets.

Common Mistake to Avoid: Don't just list these factors in an exam! Always explain how they affect a specific business function. For example: "A rise in interest rates (Economic) will increase the cost of debt, which might lead the Finance department to cancel plans for a new factory."
