Which technique involves "Three Amigos" sessions at the Delivery Horizon?

The technique that involves "Three Amigos" sessions at the Delivery Horizon is Behavior Driven Development (BDD). In BDD, the "Three Amigos" refers to the collaboration between three key roles: the business analyst, the developer, and the tester. This collaboration is crucial for fostering a shared understanding of the requirements and ensuring that all perspectives are considered when developing a feature or user story.

During "Three Amigos" sessions, these three roles engage in discussions to clarify requirements, define acceptance criteria, and create scenarios that reflect the expected behavior of the application. This collective effort helps to bridge the gap between technical implementation and business needs, promoting better quality and alignment with user expectations. The sessions also facilitate the creation of executable specifications that serve as the basis for automated testing.

Using BDD and the "Three Amigos" approach ensures that all parties involved are in agreement about what needs to be built, ultimately leading to more efficient development cycles and a higher likelihood of delivering a product that meets customer needs.
