An interview is a technique that involves a structured or unstructured conversation between the business analyst and one or more stakeholders to elicit information, opinions, or feedback about a topic. An interview can be conducted face-to-face, over the phone, or through other communication channels. An interview can be prepared in advance with a list of questions or topics to cover, or it can be spontaneous and flexible. An interview can be used to explore the needs, expectations, preferences, or concerns of the stakeholders, as well as to clarify, verify, or validate the requirements. An interview is suitable for a project involving a low number of stakeholders, as it allows the business analyst to establish rapport, ask probing questions, and obtain detailed and specific information from each stakeholder. References: PMI Professional in Business Analysis (PMI-PBA)® Examination Content Outline1, page 17; Business Analysis for Practitioners: A Practice Guide2, page 89.
