When it comes to how businesses can survive in a competitive environment, many people are looking for tools to understand what’s going on and how to stay afloat. One of these tools is Porter’s Five Forces analysis, invented by American economist Michael Porter back in the late 1970s, which is not just another textbook theory, but a real way to understand what forces are affecting your company and how to work with them. Imagine you opened a small bakery: there are already competitors around, suppliers dictate their terms, customers are capricious, and then someone else can open a similar bakery across the street. Porter offered to look at all this through the lens of five key factors that determine how profitable it is to work in your industry. Let’s take a look at what these forces are, how they work and why they are worth considering.
Porter himself believed that competition was not just about fighting with those who were already in the market, but also playing with a much broader set of players. His model helps you understand how attractive your industry is to business and what threats might be in the way. It’s like a map of the terrain: you see where the mountains are, where the rivers are, and where the road is flat. And although it’s been more than forty years since this idea was introduced, it’s still relevant, because business is basically always about money, people, and the struggle for a place in the sun. Now let’s see what this analysis consists of and how it can be useful in real life.
First force., which Porter talks about, is the threat of new competitors. Imagine that you sell coffee in your neighborhood, things are going well, customers are happy. But suddenly someone decides to open a coffee shop right across from you. If your industry is easy to enter — for example, you don’t need a lot of money, licenses or unique technologies — new players will come in all the time. It’s like there’s a lot of food in the forest: animals would come in there again and again, and then you’ll have to keep prices lower or come up with something special so you don’t lose customers. But if entering an industry is difficult – say, you need to build a factory or get a rare permit – then the threat of new competitors will be less, and you will be able to breathe a little more freely.
Second force It’s the market power of suppliers. It’s about those who give you raw materials or services that you can’t work without. Let’s say you make cakes, and there’s only one flour supplier in your city. If they suddenly raise prices or start delaying shipments, you’re in a difficult position. The fewer suppliers and the more unique their product, the more they can put pressure on you. And if there are many suppliers and their product is easy to replace — for example, flour can be bought from anyone — you’re in a better position. It’s like in life: when you have one friend who always helps out, you depend on him, and when there are many friends, you can choose.
Third Force. It’s about your customers and their ability to influence you. If you have a lot of options — say, there’s a dozen bakeries — they’re going to be capricious, demanding discounts, complaining about quality, or just going to the competition, and then they have a lot of power, and you’re going to have to adjust to keep them, and if you’re selling something that’s unique that other people don’t have, or your customers are very dependent on you, they’re going to fall. Imagine you’re the only one in town who makes a rare-flavoured cake that everyone adores—then customers will come to you, even if you raise the price a little.
Fourth Force. It’s when you sell soda, for example, and people suddenly start drinking more water or smoothies because it’s trendy or healthier. Substitutes don’t necessarily look like your product, but they solve the same problem for the customer. The more of these alternatives and the cheaper or more convenient they are, the harder it is for you to hold on. And if there are few substitutes or they’re worse than your product, the threat is minimal. It’s as if the restaurant only served your signature soup, and no one else could repeat it — the customers would go to you, not anywhere else.
Fifth force. It’s simple: the more players in the market and the more fiercely they fight, the harder it is for you to make money. If you have a dozen coffee shops in your city, and they all lower prices, make stocks and lure customers, everyone’s profits will fall. And if there are few or not too active, you’ll find it easier to stand out. It’s like a game of chess: when there are many and they’re all masters, every move is difficult, and when you play with newcomers, you feel like a king.
How does this work in practice?
Now, let’s think about how this can be applied in real life. Imagine you’ve opened a small clothing store. You look at the threat of new competitors, and you realize that it’s not difficult to open the same store, you only need money for rent and goods. So you need something that will scare off the newcomers: unique style, low prices or loyal customers. Then you assess the power of the suppliers: if one factory delivers the fabric and dictates the terms, you have to look for others or negotiate. Next, the power of the buyers: there are many stores in the area, and people will easily leave if you don’t offer something interesting. And then there’s the substitutes: all of a sudden, everyone’s buying clothes online and you don’t need your offline store? And then there’s the competition: if there’s already big brands around, you’re going to have to figure out how to stand out, for example, through sustainability or local manufacturing.
Porter came up with this model for a reason. He wanted to show that business is not only about how well you make your product, but also about how you deal with external forces. And even though his ideas were born in an era when the Internet didn’t exist, they work perfectly today. Take the smartphone market, for example. New competitors like Chinese brands are popping up all the time because technology is available. Suppliers like chipmakers have enormous power — if they delay delivery, new models will get released. Customers are capricious: almost wrong with price or quality — they will go to another brand. Substitutes like tablets or smartwatches are also under pressure, and the competition between Apple, Samsung and others is a separate story, where everyone is trying to grab market share.
By the way, five forces analysis is often used in conjunction with other tools, such as SWOT analysis, where you look at your strengths and weaknesses and your opportunities and your threats. Porter’s five forces help you understand these threats and opportunities more deeply: they show where they come from. Or PEST analysis, which looks at political, economic, social and technological factors. For example, if you have new taxes (a political factor), it can strengthen the power of suppliers or buyers. All of these models are puzzles: they are useful on their own, but together provide a complete picture.
But back to the analysis itself. It’s not just about threats, it’s about opportunities. If you realize that there are few competitors or substitutes in your industry, it’s a chance to make more money. Or if the suppliers are weak, you can dictate your terms. It’s like a poker game: you look at other players’ cards and you decide whether to take risks or wait, and although Porter wrote his theory for big companies, it works for small businesses as well. Even if you’re just baking cakes at home and selling them on Instagram, it’s helpful to know who can start doing the same thing, where to get flour cheaper, and what to do if customers suddenly switch to a keto diet.
Why is this important in 2025?
Today, in 2025, the world is changing faster than ever. Technologies like artificial intelligence and big data are adding new colors to Porter’s analysis. For example, the threat of new competitors has increased because it’s easier to open an online store than before. The power of shoppers has also increased: people read reviews, compare prices in two clicks and leave if they don’t like it. Substitutes come out of nowhere — who would have thought that electric scooters would become competitors for bicycles? And competition in some industries has gone to the point where companies almost give away goods for free to keep customers. But at the same time, data helps: you can quickly find out what your competitors are doing and adjust.
Of course, the Porter model has its drawbacks. It doesn’t take into account the internal factors of the company, like your team or your finances. And it’s a little static: it shows the situation here and now, and the world changes every day. But even with those reservations, it remains a powerful tool. It’s like an old but reliable compass: it won’t show you the exact route, but it will give you the direction, and if you learn how to use it, you can not only survive, but also win this endless game called business.
