Do this now — Quality of Diagnosis

  1. Force yourself to name the single most critical obstacle in one sentence, then defend why it outranks the others.
  2. Use an analogy or metaphor that reframes the situation ('this is a customer-trust problem, not a pricing problem') to expose its true nature.
  3. State what your diagnosis implies is NOT the problem, so you can see the domain of action it opens and closes.

About this book

An overview of the book, with source information for further reading.

In a world awash with fluffy mission statements, blue-sky objectives, and motivational slogans that are passed off as 'strategy,' Richard Rumelt argues that we have lost our way.

More on this book

'Good Strategy/Bad Strategy' cuts through the clutter to reveal what strategy truly is: a focused and coherent approach to overcoming a high-stakes challenge. Rumelt introduces the 'kernel' of a good strategy—a clear diagnosis of the problem, a guiding policy to address it, and a set of coherent actions to execute that policy. By dissecting compelling case studies from business, military, and history—from Apple's turnaround to the First Gulf War—he provides a practical framework for identifying the all-too-common hallmarks of bad strategy and equips leaders with the tools to craft powerful, effective strategies that create real competitive advantage and solve pressing problems.

In this part

What this book claims, and who wrote it.

  • — The book's one-line promise
  • — The author and where the book stands

A good strategy is a coherent response to a critical challenge, consisting of a diagnosis, a guiding policy, and coordinated actions, while the common affliction of 'bad strategy' is merely a mix of wishful thinking, buzzwords, and ambitious goals.

The need-to-know

A good strategy has a core structure called the 'kernel': a diagnosis of the challenge, a guiding policy for dealing with the challenge, and a set of coherent actions designed to carry out the guiding policy. Bad strategy is not just the absence of good strategy; it is a recognizable pattern of flaws. Its four major hallmarks are: 1) fluff (empty buzzwords), 2) failure to face the challenge, 3) mistaking goals for strategy, and 4) bad strategic objectives. The core of strategy is discovering and applying strength against weakness. This power often comes not from pre-existing advantages, but from the coherence of the strategy itself and from insightful reframings of the situation.

Set the record straight

What this book sets straight

The common beliefs this book pushes back on.

The myth

Strategy is a vision statement or a set of ambitious goals for the future.

The reality

Strategy is a coherent plan of action to overcome a specific, identified challenge. Goals are merely aspirations; strategy is the hard work of figuring out how to achieve them.

The myth

Leadership, motivation, and a positive mindset are the keys to success and are synonymous with strategy.

The reality

While important, these are not substitutes for strategy. A leader's job is to create a strategy worthy of the effort and sacrifice they ask of their people.

The myth

A good strategy should be comprehensive and try to accomplish many different objectives at once.

The reality

Good strategy requires focus and making hard choices. It is as much about what an organization will not do as what it will do.

The myth

If a strategy fails, it's usually an 'execution' problem, separate from the strategy itself.

The reality

A good strategy inherently includes a set of coherent actions. A so-called 'execution problem' is almost always a sign that the original 'strategy' was just a set of goals, not a complete, actionable plan.

The constructs

Quality of Diagnosis

The degree to which the organization's leadership has accurately identified the critical aspects of the challenge it faces, simplifying complexity to pinpoint the pivotal issues and obstacles to progress. A high-quality diagnosis explains the nature of the difficulty and defines a domain of action.

Clarity of Guiding Policy

The extent to which the overall approach for dealing with the diagnosed challenge is clear, focused, and creates or leverages advantage. It acts like a guardrail, directing and constraining action without defining its exact content, and ruling out a vast array of possible actions.

Coherence of Actions

The degree to which the set of key policies, resource commitments, and specific actions are designed to be consistent, coordinated, and mutually reinforcing in carrying out the guiding policy. Coherence creates advantage by focusing organizational energy.

Resource Focus

The concentration of organizational resources, including financial capital, key talent, and leadership attention, onto a small number of pivotal objectives rather than being spread thinly across many competing priorities.

Coordinated Effort

The degree to which the actions of different parts of the organization are aligned and working in concert toward the guiding policy, rather than operating in silos or at cross-purposes. It is the behavioral manifestation of a coherent action design.

Challenge Overcomethe outcome

The extent to which the organization successfully surmounts, mitigates, or resolves the critical challenge that was identified in the strategic diagnosis. This is the proximate outcome of a well-executed strategy.

Superior Performance

The achievement of organizational results, such as profitability, market share growth, mission success, or return on capital, that are demonstrably superior to those of direct competitors, industry averages, or past performance.

Sustained Advantage

The creation or strengthening of a competitive position that is durable over time because the underlying sources of advantage are difficult for rivals to imitate, replicate, or erode. It is the long-term outcome of consistently superior performance.

Challenge Overcome

  • Good StrategyBad Strategy
In this section

This section frames how to judge whether your strategy actually surmounted the obstacle it was built to address — the proximate result that precedes any performance gain.

Challenge Overcome

The extent to which the organization successfully surmounts, mitigates, or resolves the critical challenge that was identified in the strategic diagnosis. This is the proximate outcome of a well-executed strategy.

Why it matters. Confusing activity or partial progress with overcoming the challenge lets you declare victory while the pivotal obstacle still blocks the path to performance.

Myth

Practitioners judge success by whether the plan was executed and initiatives were completed, treating delivery as the outcome.

Reality

Executing the plan and overcoming the challenge are different things; the correct test is whether the specific obstacle named in the diagnosis has actually been mitigated or dissolved, regardless of how much activity occurred.

Tools for this
The least you need to know
  • The strategy's proximate success is whether the diagnosed obstacle receded, not whether the plan was completed.
  • Define evidence of 'overcome' in advance so you can't rationalize activity as achievement.
  • A persisting challenge is a signal to re-diagnose, not to execute harder.

In this section

This section clarifies what genuinely counts as superior results and how to attribute them to strategy rather than to luck or a rising tide.

Superior Performance

The achievement of organizational results, such as profitability, market share growth, mission success, or return on capital, that are demonstrably superior to those of direct competitors, industry averages, or past performance.

Why it matters. If you measure performance against the wrong benchmark, you can mistake industry-wide fortune for strategic skill and repeat a strategy that never actually worked.

Myth

Leaders read absolute growth or profitability as evidence of a superior strategy, without asking relative to what.

Reality

Superiority is inherently relative — to rivals, to industry averages, to your own prior baseline; strong absolute numbers in a booming market can conceal underperformance, and modest numbers in a collapsing one can be a triumph.

The least you need to know
  • Performance is superior only relative to a defensible benchmark — competitors, industry, or your own baseline.
  • Absolute growth can mask relative decline; always ask 'compared to what?'
  • Attribute performance to strategy only when you can trace it to a specific challenge you overcame.

Sustained Advantage

  • Good StrategyBad Strategy
In this section

This section explains how to make an advantage durable by grounding it in things rivals cannot easily copy, so superior performance persists rather than evaporates.

Sustained Advantage

The creation or strengthening of a competitive position that is durable over time because the underlying sources of advantage are difficult for rivals to imitate, replicate, or erode. It is the long-term outcome of consistently superior performance.

Why it matters. An advantage that competitors can quickly imitate turns a strategic win into a temporary lead, and the returns dissipate as fast as they appeared.

Myth

Practitioners believe a strong current market position or lead is itself a sustained advantage, assuming being ahead keeps you ahead.

Reality

Durability comes not from being ahead but from isolating mechanisms — capabilities, assets, or interlocked positions that raise the cost of imitation; a lead with no barrier to replication is simply a head start that rivals will close.

The least you need to know
  • Advantage endures only where imitation is costly — identify your isolating mechanism or you have no moat.
  • A market lead is not the same as a durable advantage; ask what specifically stops rivals from copying you.
  • Barriers to imitation decay, so sustained advantage requires continuous reinvestment, not just defense.

Quality of Diagnosis

  • Good StrategyBad Strategy
In this section

This section shows you how to convert a tangled situation into a single, named challenge — the analytical act that everything downstream depends on.

Quality of Diagnosis

The degree to which the organization's leadership has accurately identified the critical aspects of the challenge it faces, simplifying complexity to pinpoint the pivotal issues and obstacles to progress. A high-quality diagnosis explains the nature of the difficulty and defines a domain of action.

Why it matters. A misnamed challenge sends every subsequent resource and action in the wrong direction, so a flawed diagnosis quietly guarantees a failed strategy no matter how well you execute.

Myth

Practitioners treat diagnosis as listing all the problems and threats facing the organization, believing a thorough environmental scan is a diagnosis.

Reality

A diagnosis is an act of judgment that discards most facts to isolate the one or two pivotal obstacles; comprehensiveness is the enemy, because a list of twelve challenges is a confession that you have not actually diagnosed anything.

The least you need to know
  • A good diagnosis names one pivotal challenge and explains its nature — not a catalogue of everything wrong.
  • The test of a diagnosis is whether it makes the strategic problem simpler and defines where to act.
  • If your diagnosis could apply to any company in your industry, it is generic and has diagnosed nothing.

Clarity of Guiding Policy

  • Good StrategyBad Strategy
In this section

Here you learn to translate your diagnosis into a clear overall approach — a decision about how to grapple with the obstacle that channels action without scripting it.

Clarity of Guiding Policy

The extent to which the overall approach for dealing with the diagnosed challenge is clear, focused, and creates or leverages advantage. It acts like a guardrail, directing and constraining action without defining its exact content, and ruling out a vast array of possible actions.

Why it matters. Without a clear guiding policy, teams improvise in incompatible directions, so effort accumulates without ever compounding into advantage.

Myth

Practitioners think a guiding policy is a goal or an aspiration ('become the market leader,' 'delight customers'), so they set targets and call them strategy.

Reality

A guiding policy is a method of coping with the diagnosed obstacle — it says how you will engage the problem and, critically, which large classes of action it rules out; goals name a destination while a policy names the road and the roads you refuse.

The least you need to know
  • A guiding policy is a bridge between diagnosis and action — it responds to a specific obstacle, not to abstract ambition.
  • A real policy rules out a vast array of possible actions; if nothing is excluded, you have a slogan.
  • The policy should create or exploit an asymmetry that makes your chosen approach hard for rivals to answer.

Coherence of Actions
strong · 1 source
  • Good StrategyBad Strategy
In this section

This section covers how to design a set of actions that reinforce one another, so that your commitments multiply rather than merely add up.

Coherence of Actions

The degree to which the set of key policies, resource commitments, and specific actions are designed to be consistent, coordinated, and mutually reinforcing in carrying out the guiding policy. Coherence creates advantage by focusing organizational energy.

Why it matters. Individually sensible actions that pull against each other cancel out, wasting capital and momentum, whereas coherent actions let each move amplify the others.

Myth

Practitioners believe coherence means alignment — getting everyone to agree and pursue the same broad goals in parallel.

Reality

Coherence is about the interlocking design of actions where one commitment makes another more effective; parallel effort toward a shared goal can still be incoherent if the actions don't reinforce, and true coherence often requires some actions that look locally suboptimal.

Tools for this
The least you need to know
  • Coherence means actions that are mutually reinforcing, not just individually justified.
  • A coherent design sometimes demands moves that are inefficient on their own but powerful in combination.
  • Chained actions — where each enables the next — are the hallmark of coherence, not a checklist of parallel initiatives.

Resource Focus
strong · 1 source
  • Good StrategyBad Strategy
In this section

This section explains how to concentrate money, talent, and leadership attention on a few pivotal objectives instead of spreading them across every worthy claim.

Resource Focus

The concentration of organizational resources, including financial capital, key talent, and leadership attention, onto a small number of pivotal objectives rather than being spread thinly across many competing priorities.

Why it matters. Diffuse resources produce diffuse results — concentration at the pivot point is often the difference between a decisive breakthrough and imperceptible progress on many fronts.

Myth

Leaders believe fairness and balance require distributing resources proportionally across all business units and priorities to avoid neglecting anyone.

Reality

Strategy is inherently unfair to most claims on resources; concentration works precisely because it starves the many to overwhelm the pivot point, and the discipline is in saying no to good opportunities, not just bad ones.

The least you need to know
  • Focus means concentrating force at the pivot point, not allocating proportionally across priorities.
  • The hardest part of focus is defunding good work, not defunding waste.
  • Below a critical threshold, resources have little effect — so half-funding a priority can be worse than not funding it.

In this section

This section addresses how to get different parts of the organization acting in concert, turning a coherent design on paper into aligned behavior in practice.

Coordinated Effort

The degree to which the actions of different parts of the organization are aligned and working in concert toward the guiding policy, rather than operating in silos or at cross-purposes. It is the behavioral manifestation of a coherent action design.

Why it matters. A brilliantly coherent action design fails if units execute in silos, because strategy realizes its advantage only through what people actually do in coordination.

Myth

Managers assume coordination is achieved through more meetings, dashboards, and cross-functional committees that keep everyone informed.

Reality

Coordination is imposed by the coherent design itself — when a clear policy makes obvious what each unit should do, you need far less lateral communication; heavy coordination machinery is usually a symptom of an incoherent underlying strategy.

Tools for this
  • Nvidia's Rise in 3-D GraphicsCase study — The emerging PC 3-D graphics chip market in the mid-1990s, with competitors like 3dfx, Intel, and SGI.
The least you need to know
  • Coordinated effort is the behavioral proof of coherence — if units drift into silos, inspect the coherence of your design first.
  • A strong guiding policy reduces the need for constant coordination by making roles self-evident.
  • Persistent cross-purpose behavior usually signals misaligned incentives, not insufficient communication.

Illumination of the parts

Process 1 · named in the source

Crafting a Good Strategy (The Kernel Process)

To create a coherent and powerful strategy that focuses organizational energy and resources effectively.

  1. 1

    Diagnose the nature of the challenge by identifying the critical factors in the situation, asking 'What's going on here?'. Simplify the complexity of reality into a core issue or obstacle.

  2. 2

    Formulate a guiding policy that outlines an overall approach for dealing with the obstacles identified in the diagnosis. This policy rules out a large set of possible actions and channels effort in a specific direction.

  3. 3

    Design a set of coherent actions that are feasible and coordinated to carry out the guiding policy. These actions should be mutually reinforcing and focused on a pivotal objective.

What's underneath

What the field takes for granted

Every field runs on assumptions it rarely says out loud — the beliefs its advice quietly depends on. We surface the load-bearing ones, where they hide, and when they break. Most guides never tell you this.

Assumption 1

“A single, coherent strategy designed by a leader or a small group is the primary vehicle for organizational success.”

Where it hides

Throughout the book, particularly in the emphasis on strategy as a centrally imposed 'design' and in heroic case studies like Steve Jobs at Apple and Hannibal at Cannae.

When it breaks

This assumption downplays the role of emergent or bottom-up strategies, where valuable initiatives can arise from lower levels of an organization without being part of a grand, centrally-coordinated design.

Assumption 2

“Leaders can and should be able to perform a rational, objective diagnosis of a situation, setting aside their own cognitive biases and political pressures.”

Where it hides

The 'kernel' framework is presented as a logical structure that a skilled leader can apply. Chapter 17, 'Using Your Head,' provides tools to aid this rational process.

When it breaks

This may understate the profound difficulty of overcoming ingrained biases and the power of organizational politics, which can prevent an objective diagnosis from ever being formulated or accepted, regardless of the tools used.

Assumption 3

“The primary purpose of strategy is to solve a problem or overcome a challenge.”

Where it hides

This is fundamental to the 'kernel' framework, which begins with a 'diagnosis' of a 'challenge'. The book consistently frames strategy as a response to a high-stakes problem.

When it breaks

This problem-solving frame may not fully capture strategies that are more about opportunity creation, market shaping, or building new capabilities in the absence of an immediate, pressing challenge.

Placing the idea

How it compares — and where else it applies

We don't just explain the idea in isolation. We place it: against the alternative it replaces, and beyond the domain it was born in. That's the difference between knowing a method and knowing when to reach for it.

How it compares

vs Template-Style Strategy (Vision-Mission-Values)

What they share

Both approaches are intended to guide an organization's future direction and are often labeled as 'strategy.' Both may involve high-level leadership and goal-setting.

Where they differ

This book defines strategy as a problem-solving kernel (diagnosis-policy-action), whereas template-style strategy is an exercise in filling in blanks with aspirational statements. This book sees coherent action as integral to strategy, not a separate 'implementation' phase.

What makes this distinctive

The explicit identification of template-style strategy as a form of 'bad strategy' that is a substitute for, rather than a component of, genuine strategic work. The 'kernel' offers a concrete alternative structure.

vs Strategy as Goal-Setting or Ambition

What they share

Both recognize that organizations need to strive for improved performance and have aspirational targets.

Where they differ

This book sharply distinguishes strategy from goals. It argues that a strategy is the *how*—the coherent plan for overcoming obstacles to achieve a goal—whereas bad strategy simply states the goal and calls it a strategy (e.g., 'our strategy is to win').

What makes this distinctive

The book's central argument is that mistaking goals for strategy is a primary hallmark of bad strategy. It re-frames strategy as a problem-solving discipline rather than a motivational exercise.

Where else it applies

The model, taken beyond its home domain

Personal Career Development

An individual can use the 'kernel' to manage their career. They can diagnose their current situation (skills gap, industry trends), create a guiding policy (e.g., 'become a specialist in AI for finance'), and devise coherent actions (take specific courses, seek relevant projects, network with experts).

Public Policy and Social Initiatives

A government agency or nonprofit can move beyond vague goals like 'improve education.' It can diagnose the root cause of underperformance in a school district, establish a guiding policy like 'focus on principal leadership and autonomy,' and enact coherent actions like new training programs, revised hiring criteria, and decentralized budgeting.

Scientific Research Projects

A research lab facing a complex challenge can diagnose the primary bottleneck (e.g., 'data processing speed'), set a guiding policy ('adopt parallel computing'), and take coherent actions (acquire new hardware, retrain staff, rewrite code) rather than pursuing multiple, uncoordinated research avenues at once.

How the author makes the case

Reading well means seeing how an argument is built, not just what it claims. Here are the moves this author uses to persuade you — the technique, where it shows up, and what it's doing to you. See the machinery, and you read everything more sharply.

storytelling

In the book

The detailed accounts of historical battles (Trafalgar, Cannae, Desert Storm) and corporate sagas (Apple, Wal-Mart, Nvidia) are used throughout the book.

What it does to you

To make abstract strategic concepts concrete, memorable, and engaging. The stories serve as the primary evidence and illustration for the author's arguments.

metaphor

In the book

The core concept of 'the kernel' is a metaphor. Others include strategy as a 'lever,' a competitor's inertia as 'wrestling the gorilla,' and organizational decay as a 'hump chart'.

What it does to you

To simplify complex, abstract ideas into powerful, intuitive images that are easier for the reader to grasp and apply.

pattern_repetition

In the book

The three-part structure of the kernel (diagnosis, guiding policy, coherent action) is repeatedly applied to analyze a wide variety of examples, from military history to modern business.

What it does to you

To reinforce the book's central framework, demonstrating its versatility and training the reader to see situations through this strategic lens.

simplification_of_complexity

In the book

The entire book is an exercise in simplifying the vast, jargon-laden field of strategy into a core distinction between 'good' and 'bad,' with a simple three-part structure defining the 'good.'

What it does to you

To make the topic of strategy accessible and actionable, cutting through the noise and confusion that the author argues has come to dominate the subject.

    Good Strategy and the Kernel — Defines the positive alternative: strategy as a coherent response to a challenge built from a diagnosis, a guiding policy, and coordinated actions, illustrated through cases like Apple and the Gulf War.
  3. 03
    Sources of Power — Catalogs where strategic strength comes from — leverage, proximate objectives, chain-link systems, design, focus, growth, advantage, dynamics, inertia, and entropy — showing how coherence and reframing generate advantage.
  4. 04
    The Strategist's Thinking — Turns inward to the cognitive and scientific practices of forming strategy: treating strategy as a hypothesis to be tested, guarding against biases, and cultivating the judgment to diagnose correctly.

What it leaves unsolved

How does a leader reliably generate the correct diagnosis or insightful reframing rather than a plausible-but-wrong one?

Rumelt insists diagnosis and reframing are the crux, yet the book shows examples of good insight without a repeatable method for producing it, leaving the key creative act underspecified.

How do you evaluate a strategy before outcomes are known?

If strategy is a hypothesis judged by results, decision-makers need to commit resources in advance; the book offers little on distinguishing a good bet from a lucky one prospectively.

When is 'focus' correct versus reckless concentration?

The book praises concentrating resources and saying 'no,' but admits little about how to know when focus becomes fatal over-commitment to a wrong bet.

Where it falls short — a fair critique

incomplete

The book excels at diagnosing bad strategy and defining the kernel but provides far less on the generative process — how to actually arrive at a novel diagnosis or reframing — which is the hardest part.

illogical

Case studies are chosen after their outcomes are known, so the framework risks survivorship bias: coherent strategies that failed get little airtime, making 'coherence causes success' partly circular.

misinformed

Analogizing freely across business, military, and history assumes strategic principles transfer cleanly, but the different feedback loops, adversaries, and time horizons of these domains may limit the universality claimed.

incomplete

Rumelt acknowledges the political and psychological pain of focusing resources but offers thin guidance on navigating that organizational resistance, leaving the implementation of 'saying no' underdeveloped.

Before you apply it

Using it well

Where the method fits, who it’s for, and the honest case for and against — so you apply it where it works.

Is this book for you?

For you if

  • You lead or advise on strategic direction
  • You suspect your 'strategy' is really just goals and slogans
  • You must allocate limited resources against a serious challenge

Skip it if

  • You want detailed implementation playbooks
  • You need financial or quantitative modeling tools
  • Your role is execution rather than direction-setting

Need first

  • A concrete challenge worth diagnosing
  • Willingness to make and defend focused choices
  • Basic grasp of your competitive or organizational context

When it applies — and when it doesn’t

Use it
  • Facing a specific high-stakes competitive or organizational challenge — the kernel is built precisely for diagnosing and responding to real challenges
  • Cutting through vague mission statements and buzzword-laden plans — the bad-strategy hallmarks give a sharp diagnostic checklist
  • Deciding where to focus scarce resources amid competing interests — strategy demands the hard choice of saying no to concentrate strength
Adapt it
  • Situations demanding broad stakeholder consensus over focused choice — good strategy requires exclusion, which political settings resist
  • Highly turbulent environments with no diagnosable stable structure — diagnosis depends on discernible patterns to exploit
Not here
  • Pure operational execution or routine efficiency work — this is about strategy, not managing well-defined processes
  • Wanting a formulaic step-by-step template guaranteeing outcomes — strategy is a hypothesis requiring judgment, not a recipe

The honest case

Strongest case for

  • Distinguishes strategy from goals with a clear, memorable kernel structure
  • Names bad strategy as a recognizable pattern, making it diagnosable
  • Grounded in varied case studies from business, military, and history
  • Emphasizes coherence and focus as sources of power over pre-existing advantage

Strongest objection

  • The framework is descriptive and post-hoc; hard to operationalize prospectively
  • Case studies risk survivorship bias, explaining winners after the fact
  • 'Good diagnosis' relies on insight the book can't reliably teach
  • Focus and saying 'no' may be impractical in politically constrained organizations

Tensions — choices to make, not settled answers

Reconciled seam

Deliberate Design vs. Emergent Learning

One side emphasizes strategy as a premeditated, coherent design imposed on a system (e.g., Hannibal's plan at Cannae, Nvidia's fast-release cycle). ↔ The other side highlights the importance of learning and adaptation through experimentation (e.g., Howard Schultz modifying his espresso bar concept based on customer feedback).

How they reconcileThe book reconciles this by framing strategy as a 'hypothesis.' The initial strategy is a deliberate design, but its implementation is an experiment that generates learning, which in turn informs adjustments to the strategy.

Reconciled seam

The Value of Vision vs. The Danger of Fluff

One side harshly criticizes 'bad strategy' that consists of empty, visionary slogans and 'blue-sky' objectives. ↔ The other side acknowledges that truly great leaders like Gandhi and Martin Luther King Jr. used powerful visions to motivate people.

How they reconcileIt resolves the tension by distinguishing between vision as a *substitute* for strategy (which is bad) and vision that is integrated into a good strategy, often as a compelling articulation of a guiding policy or a proximate objective (e.g., Kennedy's moon landing goal).

  • Competitive Strategy · Michael Porter

    The book is cited as the source for the concept of a 'focus' strategy, which is analyzed in detail using the Crown Cork & Seal case. Porter's Five Forces framework is also mentioned as a tool for industry analysis.

  • Only the Paranoid Survive · Andrew Grove

    The author discusses Grove's concept of 'inflection points' as a way of understanding major industry transitions, specifically in the context of the computer industry's shift from a 'vertical' to a 'horizontal' structure.

  • The Fifth Discipline · Peter Senge

    The book is discussed and critiqued as part of the intellectual lineage that can lead to bad strategy, particularly its emphasis on 'shared vision,' which the author links to the quasi-religious 'New Thought' movement.

  • Thoughts Are Things · Prentice Mulford

    Cited as a foundational text of the 'New Thought' movement, which the author argues is a dangerous intellectual precursor to modern bad strategy that substitutes positive thinking for rigorous analysis.

How to measure it

Turning each idea into a measure

For each construct: how to operationalize it, the observable signals to look for, and how well it holds up.

Quality of Diagnosis

The degree to which the organization's strategic documents or leadership statements explicitly identify a specific, high-stakes challenge, analyze its structure, and pinpoint the key sources of difficulty or opportunity.

Observable signals
  • A clear, written statement of the primary challenge.
  • Analysis of the reasons for underperformance or the nature of an opportunity.
  • Leadership consensus on the one or two most critical issues to address.
Scale

Could be rated on a scale from 'No diagnosis' or 'Vague statement of underperformance' to 'Detailed analysis of a specific, critical challenge.'

Clarity of Guiding Policy

The existence of a stated overall approach within the strategy that provides clear direction, constrains the field of action to a manageable and advantageous arena, and is more than a restatement of goals.

Observable signals
  • A stated policy for how the organization will compete or solve the problem (e.g., 'focus on shorter runs,' 'compete by imposing asymmetric costs').
  • Explicitly ruling out certain types of customers, products, or actions.
  • A clear rationale for how the chosen approach creates leverage.
Scale

Could be rated on a scale from 'No guiding policy / only goals' to 'A clear, specific approach that creates advantage.'

Coherence of Actions

The extent to which major initiatives, resource allocations, and functional policies documented in the strategic plan are aligned with the guiding policy and with each other, showing evidence of coordinated design rather than being a disconnected 'laundry list'.

Observable signals
  • Major projects and investments directly support the guiding policy.
  • Functional policies (e.g., in marketing, operations, R&D) are aligned.
  • Absence of initiatives that conflict with each other or with the guiding policy.
Scale

Can be assessed by mapping key initiatives back to the guiding policy and checking for contradictions.

Resource Focus

The share of discretionary budget, top-quartile employee time, and senior management meeting time allocated to the top one-to-three strategic priorities as defined by the guiding policy.

Observable signals
  • A high percentage of R&D budget is on projects related to the core strategy.
  • Assignment of the best people to strategically critical projects.
  • Senior leadership agendas dominated by discussions of strategic priorities.
Scale

Can be measured through analysis of financial data, staffing records, and content analysis of executive meeting minutes.

Coordinated Effort

The observed level of cross-functional collaboration on strategic initiatives, consistency of departmental actions with the overall strategy, and speed of collective response to opportunities and threats related to the strategy.

Observable signals
  • Positive reports on inter-departmental cooperation on key projects.
  • Divisional and departmental objectives that clearly cascade from the overall strategy.
  • Quick resolution of resource conflicts in favor of strategic priorities.
Scale

Can be assessed through employee surveys, performance management systems, and qualitative interviews with managers.

Challenge Overcome

A measurable change in the status of the specific obstacle or opportunity identified in the diagnosis. This could be the neutralization of a specific competitor, the successful launch of a paradigm-shifting product, the fixing of a dysfunctional internal process, or the capture of a pivotal market position.

Observable signals
  • A targeted competitor loses significant market share or exits the market.
  • A key proximate objective (e.g., 'land a man on the moon') is achieved.
  • Metrics associated with the diagnosed problem (e.g., poor quality, slow time-to-market) show dramatic improvement.
Scale

Measurement is specific to the diagnosed challenge and often binary (achieved/not achieved) or a clear, significant change in a targeted metric.

Superior Performance

Key performance indicators (KPIs) such as return on invested capital (ROIC), profit margins, market share growth, or customer satisfaction scores that are consistently above the industry median over a business cycle.

Observable signals
  • Higher-than-average profitability.
  • Gaining market share while maintaining or increasing margins.
  • Consistently winning head-to-head against competitors.
Scale

Measured using standard, publicly available financial and market data, benchmarked against a peer group.

Sustained Advantage

The persistence of superior performance (e.g., above-average ROIC) over multiple business cycles, coupled with evidence of strong isolating mechanisms that prevent competitors from successfully duplicating the firm's sources of value creation.

Observable signals
  • A decade or more of above-average industry returns.
  • Strong brand equity and customer loyalty.
  • Proprietary technology protected by patents or deep tacit knowledge.
  • Unique business processes that are hard to replicate (e.g., IKEA, Wal-Mart's early logistics).
Scale

Assessed through longitudinal analysis of performance data and qualitative assessment of the strength of a firm's unique resources and position.

This is a structured self-diagnostic built from the model — a mirror for reflection, not a validated psychometric scale. For validated measurement, see the instruments below.

1 = Strongly Disagree · 7 = Strongly Agree

Capabilitythe practices and skills you deploy
  • I can clearly explain the specific root cause of the main challenge my organization faces, rather than just describing its symptoms.
  • Our stated approach to our main challenge is so broad or vague that it could justify almost any action we might take.
  • The key initiatives, budget decisions, and actions we pursue are deliberately designed to reinforce one another toward the same goal.
  • I concentrate the majority of my budget, top talent, and personal attention on a small number of top priorities.
  • Different teams and departments in my organization actively coordinate their actions to support our shared strategic approach, rather than working in isolation.
Alignmentthe outcomes you steer toward
  • The critical challenge we identified in our strategy has been successfully resolved or substantially reduced.
  • Our organization's financial or mission results are about the same as, or worse than, those of our closest competitors or peers.
  • The advantages we have built are still difficult for competitors to copy, even after several years.

The cheat sheet

Everything, on one page

One key takeaway from each section, with links to read more.

  • Quality of DiagnosisA good diagnosis names one pivotal challenge and explains its nature — not a catalogue of everything wrong.
  • Clarity of Guiding PolicyA guiding policy is a bridge between diagnosis and action — it responds to a specific obstacle, not to abstract ambition.
  • Coherence of ActionsCoherence means actions that are mutually reinforcing, not just individually justified.
  • Resource FocusFocus means concentrating force at the pivot point, not allocating proportionally across priorities.
  • Coordinated EffortCoordinated effort is the behavioral proof of coherence — if units drift into silos, inspect the coherence of your design first.
  • Challenge OvercomeThe strategy's proximate success is whether the diagnosed obstacle receded, not whether the plan was completed.
  • Superior PerformancePerformance is superior only relative to a defensible benchmark — competitors, industry, or your own baseline.
  • Sustained AdvantageAdvantage endures only where imitation is costly — identify your isolating mechanism or you have no moat.
