Definition
A method to build new products through hypotheses, MVPs, rapid experiments, and pivot/ persevere decisions tied to evidence.

Introduction
Plans are assumptions. Lean startup reduces waste by validating customer, problem, and solution before scaling.

Explanation

Hypothesis stack: customer → problem → value prop → channel → revenue model.

MVP types: concierge, landing page, prototype, wizard-of-oz; choose by riskiest assumption.

Experiments: define success metrics ahead (e.g., ≥8/10 problem severity, ≥20% activation).

Pivot/Persevere: cadence reviews; change one big thing or continue.

Enterprise fit: carve out procurement shortcuts, legal templates, and cloud sandboxes.

Key Takeaways

Test the riskiest assumption first.

Pre-define pass/fail to avoid bias.

Integrate with IT/Legal so experiments aren’t blocked.

Real-World Case
ING adapted lean/agile across new digital offerings; discovery sprints and MVPs cut cycle times and boosted product-market fit.
