Final answer:
The method called Behavior-Driven Development (BDD) involves collaborative creation of acceptance test criteria before development begins and is essential for ensuring the software meets business requirements.
Step-by-step explanation:
The term for a method of collaboratively creating acceptance test criteria that are used to create acceptance tests before delivery begins is Behavior-Driven Development (BDD). BDD emphasizes collaboration between developers, QA, and non-technical or business participants in a software project. This methodology encourages teams to use conversation and concrete examples to formalize a shared understanding of how the application should behave. It helps in creating acceptance criteria and associated tests which guide development and ensure that the delivered software meets the agreed-upon standards and functionality.
In the product development lifecycle, methods like BDD play a crucial role in the design phase, where teams may engage in prototyping, testing, and refinement. This iterative process is crucial to uncover hidden complexities and ensure that the design meets both the technical specifications and user requirements before final delivery.
