4.4 Strategic Frameworks: Porter's Five Forces and SWOT Analysis

Before a business commits to entering a new market, raising prices, or launching a product, leaders need a clear read on what they're walking into. Two of the most widely used tools for this are Porter's Five Forces and SWOT analysis. One zooms out to scan the competitive landscape, and the other looks both inward and outward to figure out where a business stands. Together, they help leaders make smarter strategic decisions instead of guessing.

Porter's Five Forces: Reading the Competitive Landscape

Porter's Five Forces is a framework developed by Michael Porter to evaluate the competitive intensity, attractiveness, and potential profitability of a market. When a coffee chain is thinking about expanding into a new city, or a tech startup is deciding whether to launch a streaming service, this is the tool that helps them figure out: is this market actually worth entering?

The big idea is that five different "forces" determine how tough it'll be to make money in a market. Each force represents a group that holds some kind of power over your business. If those forces are strong, the market is less attractive (lower profit potential). If they're weak, the market is more attractive (higher profit potential).

The five forces are:

1. Competitive rivalry
2. Threat of new entrants
3. Threat of substitute products
4. Customer power
5. Supplier power

Competitive Rivalry

Competitive rivalry describes how intensely existing businesses in a market fight for customers. It's usually the strongest of the five forces. Three things drive it:

• The number of rival businesses
• The degree of product differentiation (how unique each product is)
• The amount of pricing power each business has (their ability to raise prices without losing customers)

Think about the airline industry. Tons of carriers fly the same routes with nearly identical products (a seat from New York to LA is a seat from New York to LA). Customers compare prices on Google Flights in seconds. Airlines have very little pricing power, so rivalry is intense.

Compare that to Apple in the premium smartphone space. Yes, Samsung and Google exist, but Apple has built a differentiated product and ecosystem that lets it charge $1,200+ for a phone. Rivalry exists but isn't as crushing.

Threat of New Entrants

The threat of new entrants is about how easily new businesses can jump into the market. This is determined by barriers to entry: the obstacles that make it hard for newcomers to compete.

High barriers (low threat) might include:

• Huge startup costs (think: building a semiconductor factory)
• Strong brand loyalty to existing players
• Patents or regulatory licenses
• Economies of scale that new entrants can't match

Low barriers (high threat) might include:

• Cheap, easy-to-access technology
• No special licenses required
• Little customer loyalty

Opening a food truck has low barriers. Launching a new commercial airline has very high barriers.

Threat of Substitute Products

Substitute products are goods or services that meet the same customer need but aren't direct competitors. Netflix's direct competitors are Hulu and Disney+. Its substitutes are YouTube, TikTok, video games, and honestly, going outside.

The threat is strong when customers have lots of alternatives, especially if those alternatives are cheaper, easier to access, or higher quality. Coca-Cola's direct rival is Pepsi, but bottled water, energy drinks, and even tap water are substitutes that pull customers away from soda entirely.

Customer Power

Customer power is the buyers' ability to push prices down or demand more value. It's shaped by:

• The number of customers (fewer customers = more power per customer)
• Customer acquisition costs (how much a business spends to win each new customer)
• Switching costs: the monetary and psychological costs a customer takes on when they change brands or products

Customer power is strong when:

• There are few customers and each one represents a big share of sales
• Acquisition costs are high
• Switching costs are low (easy for customers to walk away)

A defense contractor selling to just the U.S. government has one massively powerful customer. On the flip side, a customer switching from Gmail to Outlook has to migrate years of emails and contacts, so switching costs are high and customer power is weaker for Google.

Supplier Power

Supplier power describes the ability of resource providers to raise input costs, meaning the prices they charge for raw materials, component parts, or services. The fewer suppliers there are, and the harder it is to switch between them, the more power they hold.

A great example: TSMC manufactures the advanced chips used by Apple, Nvidia, and AMD. There are almost no alternatives at that level of technology, which gives TSMC significant supplier power. Compare that to a clothing brand sourcing cotton t-shirts. There are thousands of factories worldwide, switching is easy, and supplier power is weak.

Applying Porter's Five Forces

Knowing the five forces is one thing. Actually using them to evaluate a market is the skill that matters. The general rule:

• Strong forces = less attractive market = lower profit potential
• Weak forces = more attractive market = higher profit potential

Here's how a business would walk through each force when deciding whether to enter, say, the meal kit delivery market (think HelloFresh, Blue Apron):

Competitive rivalry: Many direct competitors (HelloFresh, Blue Apron, Home Chef, Factor) offering similar products. Differentiation is limited. Pricing power is low. → Threat is strong.

Threat of new entrants: Startup costs are moderate, but established players have brand recognition and supply chain advantages. → Threat is moderate.

Threat of substitutes: Customers can grocery shop, order DoorDash, or eat out. Tons of substitutes exist, often cheaper or more convenient. → Threat is strong.

Customer power: Millions of individual customers, but switching costs are basically zero (cancel anytime). Acquisition costs are high because of heavy marketing spend. → Threat is strong.

Supplier power: Many food suppliers available. Switching is relatively easy. → Threat is weak.

Add it up: most forces are strong, so this market is tough to profit in. That actually matches reality, since several meal kit companies have struggled financially.

When you do this analysis on the AP exam, the key is to identify which specific factors (number of competitors, switching costs, barriers to entry, etc.) make each force strong or weak. Don't just say "rivalry is strong." Explain why.

SWOT Analysis: Looking Inward and Outward

SWOT analysis is a framework used to evaluate internal and external factors that influence a business's ability to accomplish its goals and remain competitive. While Porter's Five Forces is all about the external competitive environment, SWOT covers both what's happening inside the business and what's happening outside it.

The four factors are:

• Strengths (internal, positive)
• Weaknesses (internal, negative)
• Opportunities (external, positive)
• Threats (external, negative)

The trick to remembering the split: Strengths and Weaknesses are things the business controls. Opportunities and Threats come from the outside world and are largely beyond the business's control.

Strengths

Strengths are internal advantages that help a business compete. They include things like:

• Core competencies (what the business does exceptionally well)
• Brand recognition
• Intellectual property (patents, trademarks)
• Product quality
• Ample funds
• Skilled employees
• Supply chain efficiency

Costco's strengths include its massive purchasing power, loyal membership base, and reputation for value. Those are advantages competitors can't easily replicate.

Weaknesses

Weaknesses are internal disadvantages that hold a business back:

• Missing core competencies
• Low brand recognition
• Product flaws
• Limited funds
• Inability to hire skilled employees
• Poor customer service
• Outdated technology
• Supply chain risks

A small regional restaurant chain might have great food (strength) but limited marketing budget and no online ordering system (weaknesses).

Opportunities

Opportunities are external factors that could help the business if it acts on them. The business doesn't control these, but it can take advantage:

• Market growth (more customers entering the market)
• Reduced competition (a rival goes out of business)
• Technology advancements (new tools to lower costs or reach customers)
• Favorable changes in government regulation

When several traditional retailers shut down during the 2010s, e-commerce companies like Amazon saw a major opportunity to capture their customers.

Threats

Threats are external factors that could hurt the business:

• Rising input costs
• Natural disasters
• Unfavorable changes in government regulation
• Disruptive innovation (a new technology or business model that fundamentally changes how customers meet their needs)

Blockbuster's biggest threat wasn't another video rental chain. It was Netflix, which disrupted the entire concept of renting a physical movie.

Applying SWOT Analysis

Doing a SWOT analysis well means going beyond just listing items. You have to evaluate the business's internal capabilities (financial resources, physical resources, human resources, and intangible assets like brand and reputation) against rivals, industry benchmarks, and past performance. A "strength" only counts as a strength if it actually gives you an edge compared to someone else.

For external factors, businesses look at:

• Potential market size
• Customer preferences
• PESTEL factors: Political, Economic, Social, Technological, Environmental, and Legal forces shaping the broader environment
• Porter's Five Forces (yes, the two frameworks plug into each other)

Here's a quick SWOT for Tesla as an example:

The point of doing this isn't just to fill out the grid. Businesses use SWOT results to make strategic decisions:

• Build on strengths (Tesla leans into its tech leadership with new models)
• Address weaknesses (improve quality control to reduce recalls)
• Capitalize on opportunities (expand into new countries while EV demand grows)
• Respond to threats (cut prices to defend market share from competitors)

The connection between the two frameworks matters. Porter's Five Forces helps you understand the competitive environment, which then feeds directly into the Opportunities and Threats sections of a SWOT. A market where rivalry is weak and barriers to entry are high? That's an opportunity. A market where supplier power is rising fast? That's a threat. Used together, these tools give a business a much fuller picture of where it stands and where it should go next.
