Discovery

Makes domain knowledge visible as a chronological wall of events, from domain events through commands to bounded contexts.

Core question: Which business events, triggers, and boundaries shape the flow, and where do friction, risk, or learning needs arise?

• 2-8 h
• 5-12

Sharpens product goal, target group needs, core features, and assumptions into a shared working picture.

Core question: Which product outcome, for whom, and with which smallest useful scope?

• 1-2 h
• 2-8

Links outcomes, opportunities, solution paths, and experiments into a tree that makes discovery work steerable.

Core question: Which evidence-grounded paths can achieve the desired outcome through customer needs and tested solutions?

• 1-2 h Setup, laufend
• 2-6

Condenses conversations into themes, insights, and questions so needs and patterns become visible with evidence.

Core question: Which experiences, needs and motivations shape this situation, and what do we still need to learn?

• 30–60 min per interview
• 1 participant per interview

Clarifies options, criteria, and risks by framing the initiative or decision, collecting implicit assumptions, and planning tests or research.

Core question: Which unproven assumption would endanger the initiative most if it were false?

• 45-90 min
• 2-8

Clarifies customer problems, solution ideas, and evidence by framing an opportunity hypothesis, recruiting participants, and turning insights into opportunities.

Core question: Which needs emerge from a specific lived situation?

• 30-60 min je Interview
• 5-12 Interviews

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

Core question: Which real problem matters enough to this target group that they already act on it?

• 30-60 min je Interview
• 5-12 Interviews

Measures real interest in an idea that has not been built yet, through clicks, sign-ups, or other interest signals.

Core question: How many relevant people actually try to access this specific offer?

• 1-5 Tage
• Nutzertraffic

Personally guides early users through the service and shows which steps should later be automated.

Core question: Which value do people actually use when we deliver it personally?

• 1-4 Wochen
• 3-10 Kunden

Collects the starting situation, assumptions, and boundaries, and turns them into a precise problem statement.

Core question: Which concrete problem for which people in which context is evidenced, meaningfully bounded, and open to several solutions?

• 60-120 min
• 4-10

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 critical assumption will we test through what observable behaviour, and which pre-set threshold decides?

• 30-60 min
• 1-5

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 would damage the idea most if false and currently has the weakest credible evidence?

• 1-2 Wochen pro Iteration
• 2-6

Moves customer problem, solution idea, and evidence toward a concrete result through "take over the hypothesis list", "define the risk scale", and "select the top hypotheses for the next tests".

Core question: Which hypothesis will reduce the most decision risk next for a reasonable testing effort?

• 60-90 min
• 3-8

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 smallest test provides enough evidence for each critical assumption to support the next investment decision?

• 45-75 min
• 2-8

Moves customer problem, solution idea, and evidence toward a concrete result through "collect outcomes from discovery", "define an importance scale", and "calculate and sort the score".

Core question: Which important user outcomes are currently underserved in the target segment?

• 60-120 min
• 3-6

Moves ideas, open questions, and testable next steps toward a concrete result through "place the core idea in the center", "label the six points with who, what, when, where, how, and why", and "mark gaps and follow-up questions".

Core question: Which decision-relevant questions about this idea still need answers?

• 30-60 min
• 3-10

Separates discovery and delivery so that validated stories only move into implementation after learning loops.

Core question: Which solution is valuable, usable, feasible, and viable enough for delivery?

• Laufend, Wochen bis Monate
• 4-10

Uses a recurring learning loop to connect direction, current condition, target condition, and the next smallest experiment.

Core question: Which obstacle separates the current state from the next target condition, and what experiment addresses it?

• 1-2 Wochen je Loop
• 3-10

Aligns business problem, users, outcomes, solution ideas, hypotheses, and experiments on one lightweight canvas.

Core question: Which assumption must hold for a solution to move user and business outcomes, and how will we learn?

• 2-3 h
• 3-8

Condenses hypothesis, test, metric, and success threshold onto one card before execution.

Core question: How will we test this critical assumption with a clear test, a suitable metric, and a success threshold set in advance?

• 20-35 min
• 1-5

Separates hypothesis, observation, insight, and next action into four fields after a test.

Core question: What did we actually observe from this test, what may we learn from it, and what action follows?

• 25-40 min
• 1-5
