When conducting an event-based elicitation task, such as a requirements workshop, it is crucial to establish ground rules with the participants. Ground rules help create a structured environment, ensure all participants understand the expectations for behavior and participation, and contribute to the effectiveness and focus of the workshop. This framework sets clear boundaries and maintains order, facilitating productive discussions and capturing accurate requirements. While other elements like cost management, deadlines, and the purpose of the workshop are important, they either pertain to project management or are typically clarified beforehand. Ground rules are unique in their role of fostering a conducive environment for the elicitation process.
