Three Amigos
A practice bringing together a business perspective, a development perspective, and a testing perspective to review a story before or during a Sprint.
What it means
Three Amigos is not part of official Scrum; it originates from behavior-driven development practice. Typically a Product Owner, a Developer, and a tester examine a story together to catch ambiguity early.
The conversation surfaces edge cases and missing acceptance criteria before work starts, reducing rework and back-and-forth later in the Sprint.
Common mistakes
Despite the name, more than three people, or different specialties, can participate; the point is diverse perspectives reviewing the same requirement before commitment.
Example
Before Sprint Planning, a Three Amigos session on the refund story uncovers an untested edge case for partial refunds.
