This is the only guide you’ll ever need for Porter’s Five Forces with guides, examples and more…

Porter’s Five Forces is a framework to analyse the potential profitability of a marketplace. It was invented by Michael Porter in 1979 and has been used consistently by thousands of companies across the world since originally being published.

Five Forces looks at five key areas in a market that impact your price and profitability. The forces analysed are:

  • Power of Buyers
  • Power of Suppliers
  • Threat of Substitutes
  • Threat of New Entrants
  • Competitive Rivalry

Each of the above is rated High, Medium or Low. Ideally, you want all forces to be low. This gives you the most flexibility and control. If every force is high, you have some issues and need to take action in order to improve your position and profitability.

This article will help you produce the best possible Five Forces, putting you in a great position to move the business forward and address your market challenges.

Porter’s Five Forces Examples

Every Five Forces Analysis is different because it’s always very specific to a market. Despite this, examples always help you consider factors in your own market. There may be shared attributes with your industry or it may stimulate your own thinking.

It’s always worth looking at previous work people have done if you’re about to do a Five Forces. You’ll find many examples in Lucidity, of course, but we’ve also pulled together some different resources:

As you go through these examples consider how each one is rated High, Medium, or Low. What similarities are there with your own markets, and are you comfortable with how you rate your own forces?

There are a number of ways you can map out your Five Forces Analysis, despite the somewhat unusual diagram normally associated with the model. It often looks like this image:

Word & Excel:
Five Forces in Word and Excel is often relegated to becoming a long list of items under certain headings which, while effective and scalable, is not interesting or engaging. It tends to look more like a Risk Assessment than a market analysis framework and can lead to difficulties around consistency and version control.

PowerPoint does a more effective job of Five Forces than it’s Office siblings. The slides allow you to create the model on a single page and enter the data in a way that allows the end user to review all the forces in one place. The disadvantages of Word and Excel are somewhat shared though, in that you’ll still have issues of consistency and version control. It’ll also likely get buried in some cloud-based document folder, never to be found again…

Five Forces lends itself to group discussion, as you want to have market experts from sales and marketing in the room. You’re examining the external market in quite a bit of detail and the impact on your operations, so a whiteboard can be an effective way to capture the information. What you do after that though can be problematic, as you need to summarise and communicate your findings.

Five Forces Software:
Software for Five Forces is the best option, it allows remote collaboration, capturing of information, and a direct link to your strategy plan.

Five Tips on Five Forces

There’s a strong theme of the number five today, so here are five top tips around completing Five Forces…

“The basic idea of the competitive forces starts with the notion that competition is often looked at too narrowly by managers. Five Forces say yes, you’re competing with your direct competitors, but you’re also in a fight for profits with a broader extended set of competitors – customers, suppliers, new entrants, substitutes.”
Michael Porter, interview from HBP

“The thing to remember is that Porters Five Forces is all about understanding likely profitability in a marketplace. Once you appreciate that, its a great tool to understand the pressures going on within a marketplace and how you can mitigate those things – through product development, pricing strategies, buying strategies, marketing activity etc and of course these ideas end up in your strategy and help you move forward and grow.”
Tom Ricca-McCarthy

“Five Forces is detailed enough to really identify your weakest points in a market and so helps you plan on how to adapt and improve. Make sure you involve people from across the business as the 5 forces are distinct and you need input on each one to really nail this analysis.”
Mike Fahey

"I take all new marketing team members through a Five Forces analysis of our marketplace when they join the company. It’s a very quick way of helping them to understand the environment we’re operating within. Of particular importance for the marketing team is the competitive rivalry force. A marketer needs to understand how competitors interact and co-exist within their space so they can devise the right marketing strategies and tactics to bring success. For example, you cannot get your positioning and messaging right without understanding how competitors differentiate themselves. Also, a marketer needs to know if they are defending market-share or trying to win it – the tactics will be different! They need to know if there are lots of other providers in the space and how easy and commonplace is it for customers to switch between them – that will influence how they allocate budget and focus between retention campaigns and lead generation. The list goes on!"
Megan Saker

"Five Forces is a model easily understood and frequently used by business students. It’s a popular tool for analysis of a marketplace precisely because of its ease of use. Breaking down the analysis into these five different components makes the task of assessing the viability of a marketplace less daunting and more easily managed. Of course, using the model in an academic setting is one thing, but if Five Forces is going to be a useful tool to inform a business’ strategic plan, then it’s important to book in a follow-up session with your leadership team and go through each section of the model discussing where there may be opportunities, where you need to strengthen your product or service, where you need to focus your marketing efforts and where you need to make changes to capitalise on any growth potential."
Hugh Varilly, Visiting Professor at University College London
