Which elicitation technique uses storytelling or scenario writing to gather requirements?

The technique that uses storytelling or scenario writing to gather requirements is user stories. User stories are a powerful method in agile development that encapsulates requirements in a simple narrative form. They typically follow a structured format that highlights the user's perspective and needs, typically articulated as "As a [user role], I want [goal] so that [reason]."

This approach helps in contextualizing requirements by framing them within real-world scenarios that are relatable to the stakeholders. Storytelling allows stakeholders to visualize the use of a system or product in their daily life, making it easier to identify and articulate what they truly need and expect from the solution being developed.

In contrast, interviews primarily focus on direct question-and-answer dialogues with stakeholders, which may not provide the narrative context and may limit creative insight. Surveys gather data through predefined questions and do not allow for the same level of depth that storytelling can provide. Focus groups involve group discussions that can generate a variety of insights but may not create a single cohesive narrative needed for comprehensive requirement gathering. Therefore, user stories stand out as the technique that best employs storytelling for requirements elicitation.
