Turns ideas, open questions, and testable next steps into a tangible result by mapping the challenge, sketching solutions, and testing with users.

Core question: What solution sketch for the core sprint question yields a testable prototype in four days that can be tested with real users on Day 5?

Turns observations, needs, and patterns into a tangible result by selecting tasks, recruiting participants, and prioritizing fixes.

Core question: Can typical users complete the central tasks successfully, efficiently, and satisfactorily, and where do they fail on what?

Turns customer problems, solution ideas, and evidence into a tangible result through collecting assumptions, rating importance, and planning tests.

Core question: Which assumptions do we need to validate first because they are both critical to the initiative and uncertain?

Turns funnel performance, user behavior, and experiments into a tangible result through defining the hypothesis, planning metrics and sample size, and interpreting results.

Core question: Does the variant deliver a statistically significant effect on the success metric without degrading the counter-metric?

Turns observations, needs, and patterns into a tangible result by defining a research question, building a questionnaire, and analyzing results.

Core question: Which patterns, frequencies or priorities appear in a sufficiently large target group?

Clarifies customer problems, solution ideas, and evidence by framing problem hypotheses, recruiting the target group, and assessing problem risk.

Core question: Is the assumed problem real, frequent and painful enough for the target person to justify solution investment?

Clarifies customer problems, solution ideas, and evidence by preparing a solution concept, recruiting target customers, and deriving risks and next tests.

Core question: Does the target person understand the solution, see its value for their concrete problem, and would they be willing to invest effort or money in it?

Turns customer problem, solution idea, and evidence into a tangible result by defining the hypothesis and target signal, shaping the fake door, and deciding what to learn next.

Core question: Does the measured demand at the fake-door entry clearly confirm the demand hypothesis above the predefined success threshold?

Turns customer problem, solution idea, and evidence into a tangible result by defining the critical experience, preparing the manual simulation, and evaluating behavior and effort.

Core question: Does the simulated automatic experience deliver recognizable value to users, and which tasks are realistically automatable?

Turns customer problem, solution idea, and evidence into a tangible result by choosing target customers, delivering the outcome manually, and extracting productizable patterns.

Core question: Does the manually delivered service actually give customers the promised value, and which service elements can later be productized?

Turns customer problem, solution idea, and evidence into a tangible result by formulating the value proposition, creating the landing page, and evaluating messaging and offer.

Core question: Does the formulated value proposition convert enough target-visitor traffic into leads to support the hypothesis?

Moves architecture context, options, and consequences toward a concrete result through "place the architecture diagram or plan in the center", "set risk categories such as technical, organizational, and external", and "assign an owner and next steps for each top risk".

Core question: Which risks are embedded in this architecture or plan artifact, and which of them need action before the next iteration?

Moves customer problem, solution idea, and evidence toward a concrete result through "clarify the learning goal and the assumption to test", "formulate the hypothesis as an if-then statement", and "define the decision rule after the test".

Core question: Which assumption are we testing with which experiment, at what threshold is the hypothesis confirmed, and what decision follows from the result?

Moves customer problem, solution idea, and evidence toward a concrete result through "collect assumptions explicitly", "rate uncertainty and leverage for each assumption", and "decide to pivot, persevere, or stop".

Core question: Which assumption, if false, would endanger the initiative most, and what is the smallest possible test to examine this in 1-2 weeks?

1-2 Wochen pro Iteration

Moves customer problem, solution idea, and evidence toward a concrete result through "list assumptions", "map assumptions to dimensions", and "derive the test plan".

Core question: Which test format best fits each assumption, and which mix of formats tests the open assumption pipeline most efficiently?

Validation shapes define required classes, properties, and constraints before graph data enters production pipelines.

Core question: Which shapes define required properties, data types, cardinalities and relationships so that real data becomes validatable and contracts between producer and consumer are unambiguous?
