Primes¶
- Adaptive Redirection
- Adaptive redirection is the response to evidence that turns against a course of action: the agent selects a materially different course, holds the objective fixed across the change, and deliberately makes something the failed course produced — knowledge, capability, tooling, data, relationships — do load-bearing work on the new path.
This sourceDefines the pivot as a change of strategy under an overarching vision that rarely changes, keeping validated learning from the abandoned strategy in play.

- Gall's Law
- In lean-startup and venture methodology, the minimum-viable-product doctrine is Gall's Law made operational: every release must be a working product, however minimal, and the chain of releases is the growth path.
This sourceOperationalizes the minimum-viable-product doctrine — every release must be a working product, however minimal — as Gall's Law applied to ventures.

Blurb shows Ries aimed the method at both garage startups and Fortune 500 firms, but does not mention MVPs, public-sector agile, or corporate innovation programs.
“This is just as true for one person in a garage or a group of seasoned professionals in a Fortune 500 boardroom.”

- Wizard Of Oz Prototyping
- Organisational pilots and process design — a new internal process is run with manual handoffs and spreadsheets before the system that will automate it is specified.
This sourceDefines the 'concierge' and 'Wizard of Oz' MVP patterns — an apparently automated product with a manual back end — and the build-measure-learn staged-commitment discipline for validating demand before building, including running a process manually before automating it.
Supported in partVerified against the publisher's abstract
The publisher's page confirms Ries's validated-learning, test-before-you-build thesis, but neither names build-measure-learn nor supports the claim that this part of the pattern transfers most cleanly.
“Inspired by lessons from lean manufacturing, it relies on “validated learning,” rapid scientific experimentation, as well as a number of counter-intuitive practices that shorten product development cycles, measure actual progress without resorting to vanity metrics, and learn what customers really want.”

Domain-specific¶
- Customer-Discovery Theater
- Naming the theater pulls apart three things that the phrase "we did customer discovery" otherwise fuses into one reassuring claim. Confirmatory inquiry seeks evidence for the hypothesis — methodologically weak, but still responsive if the contradiction is loud enough. Disconfirmatory inquiry is framed to surface what would kill the hypothesis — the posture the methodologies (Lean Startup, Design Thinking, JTBD) intend
This sourceRies's method supplies the disconfirmation-permitting posture — validated learning, build-measure-learn and the pivot-or-persevere decision — for Lean Startup only, not for Design Thinking or Jobs-to-be-Done.

- Pivot Thrashing
- The canonical intervention is pivot-criterion discipline: before launching a new direction, the team specifies what evidence would justify staying the course and what evidence would justify another pivot, how long the current direction is allowed to run before that evidence is read, and who has authority to call the direction change.
This sourceRies’s prescription that a startup hold a regular, pre-scheduled "pivot or persevere" meeting, so the decision to change direction is taken on accumulated evidence rather than in the moment. That the Lean Startup’s roots are in lean manufacturing, design thinking, customer development, and agile development, and that it prizes responding to validated learning. Eric Ries’s definition of a pivot as a structured course correction, taken through validated learning, that tests a new hypothesis.

- Riskiest Assumption Test
- The riskiest assumption test (RAT), popularised in lean-startup methodology and structurally related to the "killer experiment" in pharmaceutical R&D and "critical-path test" in engineering, is the decision discipline of identifying — from the full set of assumptions a plan depends on — the single assumption that combines (a) the largest downside if false with (b) the team's weakest independent evidence for it, and then designing the cheapest credible experiment to test that assumption before committing downstream resources.

- Smoke Test
- Predictive / order-of-events — the cheap signal precedes and forecasts the expensive outcome. The concept asserts a temporal ordering — cheap probe first, expensive build only if the probe clears its threshold — and predicts that the commitment-bearing conversion rate forecasts the real adoption rate well enough to gate the decision, the prediction improving as the demanded commitment rises toward real payment

- Validated Learning
- Validated learning is Lean Startup methodology's (Ries, 2011) name for the unit of progress in early-stage venture work: learning counts only when it is grounded in observed behaviour of real customers — or credible proxy users — that confirms or refutes a specific business hypothesis, as distinct from learning grounded in opinions, stated intentions, focus-group responses, internal plans, or vanity metrics
This sourceRies's concept of validated learning as the gauge of a startup's progress, defined against after-the-fact rationalization and counterposed to vanity metrics. Ries's account of Zappos founder Nick Swinmurn testing the value hypothesis before committing to the full retail build.

Verification¶
Does it exist? Confirmed. This work's ISBN resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Read against the text for 15 of 39 citations: 1 supported, 14 supported in part. Each verdict is shown under its citation below, with what in the work backs the sentence.
Was it audited? Yes. A second, independent pass read the citation against the article text and recorded a verdict.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
