Interface analysis is not an event-based elicitation technique. Event-based elicitation techniques are methods that use scenarios, simulations, or other types of events to elicit knowledge from experts or users. Some examples of event-based elicitation techniques are focus group, interview, workshop, critical incident technique, cognitive walkthrough, and protocol analysis12. Interface analysis, on the other hand, is a technique that examines the interactions and dependencies between a system and its external entities, such as other systems, users, or hardware3. Interface analysis is not based on events, but on the characteristics and requirements of the interfaces.
