What elicitation techniques for requirements exist?

There are various elicitation techniques that help identify and clarify the needs of clients and users:

• Interviews — conducting conversations with stakeholders to gather information.
• Questionnaires and surveys — collecting data through standardized questions.
• Workshops and brainstorming sessions — group discussions to generate ideas and requirements.
• Document analysis — studying existing documentation, specifications, and regulations.
• Observation — studying real processes and user behaviors.
• Prototyping — creating models or mock-ups to refine requirements.
• Use Cases and User Stories — describing system usage scenarios.
• Focus groups — discussions with a group of users to identify needs.

The choice of technique depends on the project context, available resources, and the type of requirements.
