Is this strategy any good?
/100
80–100: high value. 70–79: worth the time. Below 70: below the usual publication threshold.
Evidence-reviewed score based on available publisher text. Evidence appears complete enough, though examples from companies are necessarily context-limited by the author's own caveat.
Scores reflect one reader’s profile, not an objective quality rating. Best is a separate personal selection.

Why read this
Strategy quality depends on refinement speed, learning cost, fit to diagnosis, and which phase of the strategy is being judged.
AI brief · Checked against source text
The main idea
The author argues that strategy cannot be judged only by outcomes, inputs, or elegance of format. Good evaluation must ask how quickly the strategy improves, how costly that learning is for the organization, whether the current version addresses its diagnosis, and which phase of the strategy is being judged. This works because strategies age as new information makes the original diagnosis incomplete, so ending or changing one can be evidence of judgment rather than failure.
Go a little deeper
Outputs hide the counterfactual
Judging by results alone confuses what happened with what the strategy caused. The author distinguishes a strategy’s added value from the expected outcome without it: a successful result may have happened anyway, and a visible win may still have been bought at an unsustainable cost. This makes imitation especially dangerous when outsiders copy only the public result, not the conditions that made it work.
Inputs cannot excuse irrelevance
A well-reasoned diagnosis and coherent policy are not enough if the strategy fails to affect the world it is meant to change. The author’s test is iterative: a conceptually sound strategy that struggles should be refined in response to evidence. If its authors ignore signals that it is not working, the defect is no longer merely execution but the strategy practice itself.
Cheap learning is part of quality
The rubric treats the cost of refinement as central, not secondary. A strategy that requires expensive coordination, burdens implementing teams, or lacks workable operational mechanisms may be abandoned before it can be validated. Early strategy should therefore be designed to learn cheaply enough that the organization can actually afford to improve it.
Bad strategies can be better teachers
The author rejects the habit of learning only from admired strategies. Failed strategies often contain successful early phases and fail for diagnostically useful reasons: missing mechanisms, bad policy fit, ignored constraints, or leadership problems. The practical move is to map the phases and locate where the failure occurred, so the lesson is specific rather than a vague verdict.
A case from the article
Uber’s service migration changed phase
Uber’s service migration initially addressed developer productivity problems in the monolith and, in the author’s judgment, improved rapidly, kept adoption costs low, and solved its first diagnosis well. Later, widespread service architecture created a new developer productivity problem. The same strategy therefore deserved different assessments across phases: strong in the first, weaker once its own consequences became the next diagnosis.
How the case is made
The case is made through practitioner observation, rubric-building, and examples from Uber, Stripe, Digg, LLM adoption, and internal strategy work.
Where the idea has limits
The author explicitly warns that evaluating other companies’ strategies from the outside should carry low confidence because the hidden phases, costs, mechanisms, and even the real strategy may be invisible.
A question to take away · from Digna Legi
Which current strategy are you treating as one fixed decision when it may already have entered a new phase?
What the original adds
The source adds a fuller critique of input-only and output-only grading, plus several additional examples showing how apparently successful or failed strategies can teach different lessons.
