Which of the following types of surveys is typically conducted after a specific event?

The correct choice is one-time or event-based surveys, as these are designed to gather feedback or data immediately following a specific event. This could include things like a product launch, a training session, or any other significant occurrence. Conducting a survey right after an event allows for the collection of timely and relevant information that reflects participants' immediate reactions, experiences, and suggestions for improvement.

These surveys are particularly useful for measuring the effectiveness of the event and determining areas for future enhancement. Collecting feedback shortly after the event ensures that the details are fresh in the respondents' minds, leading to more accurate and constructive insights.

In contrast, ongoing surveys are typically conducted at regular intervals and are designed to track trends over time rather than capture immediate responses. Annual surveys focus on a broader perspective and usually assess performance metrics or satisfaction levels over the course of a year. Periodic surveys also involve data collection at scheduled intervals, but like ongoing surveys, they do not focus specifically on the feedback needed right after a relevant event.
