What methodology may be employed at the Delivery Horizon to clarify stakeholder requirements?

Behavior Driven Development (BDD) is an effective methodology employed at the Delivery Horizon to clarify stakeholder requirements. BDD focuses on collaboration between developers, testers, and business stakeholders. It emphasizes the use of clear and understandable examples, which helps ensure that all parties share a common understanding of the functionality to be developed.

By using scenarios to describe how the system should behave in specific situations, BDD enables stakeholders to visualize requirements in a manner that is relatable and easy to grasp. This interactive approach encourages communication and reduces ambiguity, ensuring that the development team delivers what stakeholders expect.

The other methodologies mentioned serve different purposes. Lean Analysis tends to focus on eliminating waste and optimizing processes rather than directly clarifying stakeholder requirements. Value Stream Mapping is used to visualize the steps involved in a process and identify areas for improvement, but it does not specifically clarify requirements. Root Cause Analysis is primarily concerned with identifying the underlying causes of issues rather than defining or clarifying stakeholder needs. Thus, BDD's focus on behavior and collaboration makes it the most suitable choice for enhancing clarity around stakeholder requirements at this stage.
