Guide for the Concept of the Three Amigos in PMI-ACP

The 'Three Amigos' concept refers to three roles that collaborate together to produce a requirements document or user story, those being: 'The Business Analyst (The One who Describes)', 'The Developer (The One who Creates)', and 'The Tester (The One who Checks)'. The aim is to cultivate a shared understanding of the product's requirements and collectively design solutions that align with them.

Why is it important?
It establishes clear communication and interaction between the three major roles involved in software development. By offering various perspectives in the planning phase, it improves the detailing of user stories, reduces ambiguities, and leads to comprehensive test cases

How does it Work?
Each 'Amigo' reviews the user story or requirement from their viewpoint, contributes insights, and raises queries about potential challenges or gaps. This collaborative session can be facilitated with techniques like Behavior Driven Development (BDD) to define the acceptance criteria.
