Explanation
The conduct elicitation activity is a technique to understand stakeholder needs and identify potential solutions that may meet those needs. It involves guiding stakeholders and collaborating with them through the elicitation activity, doing research or running experiments, and capturing elicitation outcomes1. The captured outcomes should be recorded in a format that is clear, consistent, and accessible for future reference and analysis. Text messages sent via a secured mobile phone are not an acceptable element for requirements documentation, as they are not easily retrievable, traceable, or verifiable. Written documents, visual or audio recordings, and whiteboards are acceptable elements for requirements documentation, as long as they are properly stored, labeled, and managed2.
