There may be a need for the business analyst to explain to the business stakeholders how an elicitation activity works prior to conducting the session. It may also be required by the business analyst that stakeholders prepare specific information for the elicitation session itself. 

A good practice is to ensure that the stakeholders clearly understand the purpose of the planned elicitation session and what the benefits are. This will help ensure that all stakeholders attend and come with a motivated attitude to participate actively. When stakeholders understand the goals and expectations well before the elicitation session, the session will have a much better chance of yielding high-quality requirements, so it is well worth the effort to engage stakeholders in this way before the elicitation session is conducted.

Continuing the previous example:

If you are unsure whether your insurance project's stakeholders are prepared and comfortable with what you are planning in terms of the elicitation workshops, it would be a good idea to send out a detailed agenda and make personal contact with individuals to discuss and share information of the planned elicitation activity. This way people will be more prepared and feel included, if not also positive about what you are planning.
