Books on Strategy Worth Reading After 20 Years in the Room

Books on strategy are not in short supply. The business section of any airport bookshop will give you fifteen variations on the same three ideas, dressed up in different case studies. The ones worth reading are rarer, and they tend to share a quality: they make you think differently about problems you thought you already understood.

After two decades running agencies, managing P&Ls, and watching strategy get executed well and badly across thirty industries, I have a shorter list than most people expect. Not because I have not read widely, but because most strategy books do not survive contact with a real business problem.

Why Most Strategy Books Disappoint

I remember being handed the whiteboard pen at Cybercom during a Guinness brainstorm. The founder had to leave mid-session, passed it to me without ceremony, and walked out. My internal reaction was not excitement. It was something closer to dread, followed immediately by the recognition that I had no choice but to get on with it. That moment taught me more about strategy under pressure than any book I had read to that point. Which is not an argument against books. It is an argument for reading the right ones.

Most strategy books fail for one of three reasons. They present frameworks as if the hard part is knowing the framework, rather than applying judgment within it. They use case studies selectively, choosing examples where the strategy worked and ignoring the structural conditions that made it work. Or they conflate strategic thinking with strategic planning, which are genuinely different activities.

The books I return to are the ones that treat strategy as a discipline for making better choices under uncertainty, not a process for producing comprehensive documents. That distinction matters more than it sounds.

If you are thinking about how strategy connects to commercial growth, the broader context sits in my writing on go-to-market and growth strategy, where I look at how strategic thinking translates into market decisions that actually move revenue.

Good Strategy Bad Strategy, Richard Rumelt

If I could only recommend one book on strategy, it would be this one. Rumelt’s central argument is deceptively simple: most of what organisations call strategy is not strategy at all. It is a list of goals dressed up in strategic language. He calls this “bad strategy,” and his diagnosis is sharp enough to be uncomfortable if you have ever sat in a planning cycle and watched it happen in real time.

Good strategy, in Rumelt’s framing, has a kernel: a diagnosis of the situation, a guiding policy that addresses the challenge, and coherent actions that follow from that policy. The diagnostic step is the one most organisations skip. They move from “here is our ambition” to “here is our plan” without ever clearly articulating what the actual problem is. I have seen this play out in client engagements across sectors, and it is as common in large corporates as it is in mid-sized agencies.

What makes this book durable is that Rumelt does not just describe the problem. He gives you the vocabulary to name it when you see it, which is a practical skill in any leadership context. When someone presents a strategy that is really a list of aspirations, you can now explain precisely why it is not a strategy. That changes conversations.

Competitive Strategy, Michael Porter

Porter is unfashionable in some circles now, partly because his frameworks have been taught so badly for so long that people associate them with tedious MBA exercises rather than genuine analytical thinking. That is a mistake. The Five Forces framework is not a template to fill in. It is a way of understanding the structural attractiveness of a market and where competitive pressure actually comes from.

Earlier in my career, I spent too much time focused on the bottom of the funnel, optimising for the customers who were already in the market. Porter helped me understand why that is a structurally weak position. If you are only competing for existing intent, you are competing on the terms your category has already set. Sustainable competitive advantage comes from shaping the terms of competition, not just winning within them. That insight has stayed with me across every business I have run since.

The book is dense and not an easy read. But the density is the point. It rewards careful reading in a way that most modern strategy writing does not. BCG’s work on pricing and go-to-market strategy draws on similar structural thinking, and it is worth reading alongside Porter if you are working through how market structure affects commercial decisions.

Playing to Win, Roger Martin and A.G. Lafley

This is the book I recommend most often to marketing leaders who are making the transition into broader commercial roles. Martin and Lafley’s framework, built around two core questions, where will you play and how will you win, is simple enough to use in practice and rigorous enough to produce real strategic clarity.

What I find most useful is the emphasis on choice. Strategy is not about doing everything well. It is about making deliberate decisions about where you will compete and where you will not. That sounds obvious. In practice, most organisations resist it because saying no to a market or a customer segment feels like leaving money on the table. The book makes a compelling case that the opposite is true: trying to be everything to everyone is the fastest route to being nothing to anyone.

The P&G case studies are genuinely instructive rather than self-congratulatory, which is rarer than it should be in business books. Lafley was running one of the most complex brand portfolios in the world when these decisions were being made, and the book does not sanitise the difficulty of the choices involved.

The Art of War, Sun Tzu

I include this with a caveat: it is the most over-quoted and under-read book on this list. Every second LinkedIn post about competitive strategy reaches for a Sun Tzu aphorism. Most of them are taken out of context, applied loosely, and used to make fairly ordinary observations sound more profound than they are.

Read carefully, the actual text is something different. Sun Tzu’s core argument is about information asymmetry and the conditions for winning before the battle begins. Know yourself, know your enemy, and choose your ground. Applied to commercial strategy, this translates to: understand your own capabilities honestly, understand your competitive environment deeply, and choose the markets and segments where your strengths are most relevant. That is not a complicated idea, but most organisations are poor at all three parts of it.

The book is short. Read it in translation, with a decent commentary. Skip the business-parable versions that dress it up in corporate language. The original is cleaner.

Thinking in Systems, Donella Meadows

This is not a marketing book or a business strategy book in the conventional sense. It is a book about how complex systems behave, and why interventions so often produce unintended consequences. I read it relatively late in my career and found myself wishing I had read it earlier.

When I was growing an agency from 20 to 100 people, the hardest problems were not strategic in the conventional sense. They were systemic. Changing one thing, say, how we priced projects, changed the behaviour of account teams, which changed client relationships, which changed the kind of briefs we attracted, which changed who we needed to hire. Meadows gives you the conceptual tools to see those feedback loops before you trigger them rather than after.

For marketers specifically, the book is a useful corrective to the tendency to treat marketing as a linear input-output system. Spend goes in, customers come out. That model breaks down in any market with meaningful competitive dynamics, and Meadows explains precisely why. Understanding market penetration as a systems problem rather than a media budget problem changes how you approach growth entirely.

The Innovator’s Dilemma, Clayton Christensen

Christensen’s central argument, that well-managed companies can fail precisely because they are well-managed, is one of the most important ideas in modern business strategy. The logic is counterintuitive but rigorous: companies that listen carefully to their best customers and invest in improving their best products are systematically vulnerable to disruption from below, because significant entrants initially serve markets that incumbents do not value.

I have watched this play out in the agency sector over the past decade. Large, well-run agencies focused on their most profitable clients and their most sophisticated capabilities while smaller, cheaper, faster competitors built credibility in segments the large agencies did not find interesting. By the time the threat was visible, the competitive ground had shifted considerably.

The book is most useful as a diagnostic tool. If you are a market leader, it gives you a framework for identifying where disruption is most likely to come from. If you are a challenger, it gives you a framework for finding the entry points that incumbents are structurally motivated to ignore. Both perspectives are commercially valuable. BCG’s analysis of brand and go-to-market strategy touches on similar dynamics in how large organisations structure their commercial activities.

Obviously Awesome, April Dunford

This is the most practical book on this list, and the one most directly relevant to day-to-day marketing decisions. Dunford’s subject is positioning, specifically the question of how you frame a product or service so that the right customers immediately understand why it matters to them.

I have sat in enough positioning workshops to know how badly most of them go. They tend to produce statements that describe what a company does rather than why it matters in the context of the alternatives customers have. Dunford’s framework forces a different question: what is the competitive alternative in the customer’s mind, and what do you do better than that alternative for a specific set of customers in a specific context?

The book is short, direct, and full of worked examples. It does not pretend that positioning is more complicated than it is. What it does insist on is that positioning is a deliberate choice, not something that emerges naturally from a good product. That distinction has real commercial consequences. Poorly positioned products with good marketing spend tend to generate awareness without conversion. Changing the positioning often does more for commercial performance than changing the media plan.

This connects to a broader point about how strategy and execution interact. The best strategic thinking in the world does not help if the commercial framing is wrong. That is a theme I explore across the writing on go-to-market and growth strategy, where positioning decisions sit alongside channel strategy and market entry in the same commercial framework.

The Long and the Short of It, Les Binet and Peter Field

This is the book I wish had existed earlier in my career, when I was spending most of my time on performance channels and telling myself that the attribution data proved it was working. Binet and Field’s analysis of the IPA Databank, one of the largest collections of advertising effectiveness data available, makes a clear and evidence-based case for the balance between long-term brand building and short-term activation.

The core finding is simple: most commercial growth comes from reaching people who are not currently in the market for your product, not from optimising the experience of people who already are. I came to this conclusion through my own experience before I read the book, partly through the painful realisation that much of what performance marketing takes credit for would have happened anyway. Binet and Field give that intuition a rigorous empirical foundation.

The book is slim and readable. It is also one of the few marketing books that will change what you recommend to a client, not just how you talk about what you already do. That is a meaningful test of a strategy book’s practical value. The Vidyard research on why go-to-market feels harder touches on related themes about why short-term demand capture is becoming a less reliable growth lever on its own.

How to Read Strategy Books Without Wasting Time

A few practical observations from having read a lot of these books and applied them in real commercial contexts.

Read with a specific problem in mind. Strategy books are most useful when you bring a real question to them. Reading Rumelt while you are in the middle of a planning cycle is more valuable than reading him in the abstract. The ideas land differently when they have something concrete to attach to.

Be selective about frameworks. Every strategy book comes with frameworks. Most frameworks are useful as thinking tools and dangerous as templates. The Five Forces does not tell you what strategy to adopt. It tells you what questions to ask. That is a meaningful difference, and conflating the two is how strategy work becomes box-filling rather than thinking.

Revisit books at different career stages. I read Competitive Strategy in my early thirties and found it intellectually interesting. I re-read it in my mid-forties while running a business and found it practically useful in ways I had not anticipated. The book had not changed. My ability to connect its arguments to real decisions had. That is worth knowing before you write off a book you read early in your career as not relevant.

Be sceptical of books built entirely on case studies from exceptional companies. Apple, Amazon, and Google are not useful strategic models for most businesses. Their competitive positions are so structurally unusual that the lessons do not transfer cleanly. Books that use them as primary examples tend to produce inspiring presentations and poor strategic decisions. Growth hacking examples from high-growth tech companies carry a similar caveat: the tactics that worked in specific market conditions are not always transferable to different competitive contexts.

And finally: no book replaces the experience of making actual decisions with incomplete information and real consequences. The best strategy books accelerate your thinking. They do not substitute for it. The moment you treat a framework as an answer rather than a tool, you have stopped doing strategy and started doing something that looks like strategy from a distance but produces worse outcomes.
