Business Strategy

What Is Strategy?

The power of choosing what not to do. A good strategy doesn’t lengthen the to-do list. It shortens it.

Idea in Brief

The problem: Many organizations’ strategy documents are really lists of things to do, one giant to-do list.
The core idea: Strategy is the process of choosing what not to do, so that limited time, people, and capital can be concentrated where they matter most.
The test: If you can’t answer “What have we decided not to do because of this strategy?”, what you have is a goal or an activity plan, not a strategy.

When organizations talk about strategy, they usually start with “What will we do?” Enter a new market, add a product, respond to more customer requests, launch more projects. That is why so many strategy documents end up as lists of things to do, a giant to-do list.

But the heart of strategy is not deciding to do many things. It is closer to the process of choosing what not to do, so that limited time, people, and capital can be focused in the right place.

01Strategy Starts with a Choice

Strategy is necessary because no organization can do everything well at the same time. Engineering capacity is limited. The markets a sales team can focus on are limited. Even the attention and decision-making capacity of senior leaders is not infinite. Choosing one thing inevitably means giving up another. That is where strategy begins.

“The essence of strategy is choosing what not to do.”

— Michael E. Porter, What Is Strategy?

Michael Porter distinguished strategy from simple operational effectiveness. Working faster than competitors, cutting costs, and improving quality all matter, but they rarely create lasting differentiation on their own, because competitors can improve in the same ways.

What Porter emphasized was the trade-off: choosing and giving up. If a company tries to satisfy every customer, enter every market, offer every feature, and copy everything its competitors do well, the differences between companies shrink and resources are scattered.

So strategy must decide not only which customers to serve but also which not to serve; not only which markets to compete in but also which to stay out of; not only which features to offer but also which requests to decline.

02Goals Are Not Strategy

In Good Strategy/Bad Strategy, Richard Rumelt points out that many organizations confuse goals with strategy. Statements such as “We will grow revenue by 30%,” “We will become the global market leader,” or “We will be a customer-centric company” may be goals or wishes, but they are not strategies.

According to Rumelt, a good strategy has a clear structure. It first diagnoses the most important problem (Diagnosis), then sets the overall approach for dealing with it (Guiding Policy), and then concentrates on carrying out a set of consistent actions that fit that approach (Coherent Actions).

What matters here is focus. If an organization calls ten problems its top priority, then in reality nothing is a priority. Strategy is also the process of choosing the most important problem and lowering the priority of the rest.

03Where Will You Compete?

In Playing to Win, Roger Martin and A.G. Lafley describe strategy as a series of choices. In particular, they argue that an organization must be clear about Where to Play and How to Win: where it will compete, and how it will win there.

But deciding where to compete naturally means deciding where not to compete. If you focus on a particular industry, customer segment, region, or application, you may have to say “No” on purpose to other opportunities.

In the end, strategy is less the art of seizing more opportunities than the work of building the criteria for judging which opportunities to give up.

04The Moment Everything Is Important, Strategy Disappears

One of the most common reasons strategy breaks down in organizations is that everything is treated as important. Existing customers matter, and so do new ones. New products matter, and so does improving existing ones. Short-term revenue matters, and so does long-term technology development.

The problem is that not all of these can be the top priority at the same time. If projects keep being added but none are ever stopped, if customer requests keep being accepted but there is no standard for refusing them, and if new markets keep expanding without any adjustment to the priority of existing ones, the organization may look very busy, yet it is hard to say it is strategically focused.

05The Simplest Test of a Strategy

The Test

“What have we decided not to do because of this strategy?”

If you can’t answer this question, what you have is more likely a goal or an activity plan than a strategy.

Compare the two statements below.

Weak

A statement that gives up nothing

“We will strengthen our AI products, improve existing products, enter new industries, expand into overseas markets, and actively support Custom Development for key customers.”

It sounds like an ambitious strategy, but it gives up nothing.

Strong

A statement that contains a real choice

“Over the next 12 months, we will focus 70% of development resources on our core platform and our top two applications, and we will do Custom Development for a single customer only when it can be reused on the platform in the future.”

It defines what we will do and, at the same time, what we won’t.

06A Good Strategy Creates a Not-to-Do List

A good strategy can begin by making the Not-to-Do List explicit, rather than by making the To-Do List longer. Decide five things.

✕Which markets we won’t enter this year

✕Which products and features we’ll stop investing in

✕Which customer requests we’ll decline

✕Which projects we’ll deprioritize

✕Which internal activities we’ll stop

In growing companies especially, stopping existing work is harder than starting new work. As a company grows, new customers, new projects, and new markets keep appearing. But for an organization with limited resources, what matters may be less how many opportunities you found than which good opportunities you can give up for the more important ones.

07Strategy Is the Organization’s Decision Criterion

When strategy is clear, execution changes too. Instead of waiting for leadership to decide every time, team members can judge for themselves by asking: “Does this fall under our strategy?” “If we accept this request, what more important work gets pushed back?” “Is this project for the market and customers we chose?”

In other words, strategy should not be a mere declaration of direction or an annual plan. It should be the standard by which an organization decides what to say Yes to and what to say No to, in front of countless choices.

08So, What Is Strategy?

Michael Porter’s trade-off, Richard Rumelt’s focus and diagnosis, and Roger Martin’s choice use different words but carry a common message. Strategy is not a plan to do everything well. It is the process of choosing what matters and giving up other things to protect that choice.

Michael Porter

Trade-off

Choosing and giving up. Copy everything, and differentiation disappears.

Richard Rumelt

Focus & Diagnosis

Diagnose the most important problem, then concentrate on it.

Roger Martin

Choice

Choose where to compete (Where to Play) and how to win (How to Win).

Bottom Line

Strategy is not deciding what more to do. It is choosing what not to do, so that the organization can concentrate on its most important problems and opportunities.

Strategy is not a list of everything we want to do.
Strategy is the discipline of deciding what matters most, concentrating resources on it, and deliberately choosing what not to do.

A good strategy makes an organization’s to-do list shorter, not longer. That is why the most important question in a strategy meeting is not only “What will we do?” but “To protect what we have truly chosen as most important, what will we not do, and what are we prepared to give up?”
