Lean

Condenses target group, problem, value proposition, and core assumptions into a lean picture for early product bets.

Core question: Which assumptions about problem, segment, solution, and economics must we test next?

• 45-90 min
• 1-6

Weighs work by business value, urgency, risk, and effort so that sequencing becomes economically justifiable.

Core question: Which job delivers the highest Cost of Delay divided by Job Size?

• 45-90 min
• 3-10

Maps a service's path all the way to delivery and exposes wait times, waste, and bottlenecks.

Core question: How does one concrete work item move from request to delivery today?

• 1-3 h
• 4-10

Asks its way step by step to a controllable cause and stops only once an effective countermeasure is within reach.

Core question: Which controllable cause behind the symptom can the team fix with a concrete countermeasure?

• 15-30 min
• 2-6

Condenses problem, analysis, countermeasures, and follow-up onto one sheet and forces joint analysis.

Core question: Which gap between current and target condition is evidenced, and which countermeasure will we test first?

• 45-90 min
• 2-5

Goes to the place where work happens, observes the process without disrupting it, and gathers solid clues about friction.

Core question: What is happening where work occurs, and which process question should we investigate together?

• 30-120 min
• 2-6

Runs changes as a repeatable cycle of Plan, Do, Check, and Act until a standard becomes solid.

Core question: Which small change will we test, what do we predict, what occurred, and how will learning enter the next cycle?

• 1 h bis mehrere Wochen
• 1-8

Bundles observation, waste analysis, and experiments into a compact improvement process with a new standard.

Core question: Which measurable process improvement can the frontline team implement, test, and standardise at the gemba within days?

• 0.5-5 Tage
• 4-10

Compares work as actually performed with the standard and reveals deviations that improve the process in a targeted way.

Core question: Which safe, quality-capable sequence meets customer takt with the minimum required standard WIP?

• 1-3 h
• 2-6

Identifies waste along a process, prioritizes impact, and derives improvements.

Core question: Which work creates customer value, which waste is immediately avoidable, which is currently necessary, and which unevenness or overburden produces it?

• 45-120 min
• 2-8

Build Measure Learn cycles turn risky assumptions into experiments that support persevere, pivot, or stop decisions.

Core question: What smallest experiment creates decision-ready learning about the riskiest assumption?

• Wochen bis Monate je Lernzyklus
• 2-8

Helps a small team assess the main quality risks in its software and choose where to investigate further.

Core question: How well does our software meet its quality goals, and which risks should we investigate further?

• 3–4 h for initial assessment; preparation and deeper analysis additional
• 1 or a small team; particularly suitable for 3–4 people
