Which one of the following requirements elicitation techniques would not normally be appropriate for engaging a numerous stakeholder group?

Interviewing is typically a one-on-one technique that allows for deep, detailed conversations with individual stakeholders. While interviews can provide valuable insights, they are not practical for engaging with large groups of stakeholders effectively. This is primarily due to the time and resource constraints involved in scheduling and conducting numerous interviews, as well as the difficulty of capturing diverse opinions within a limited timeframe.

On the other hand, tools like questionnaires and surveys are designed to collect data from many individuals simultaneously. They allow for standardized questions to be distributed to a large group, facilitating the aggregation of responses quickly and efficiently. Sampling, while also a technique that can involve larger groups, often refers to selecting a small, representative subset of a larger population to gather insights. However, it still allows for broader engagement than individual interviews.

Therefore, in contexts where engaging a large number of stakeholders is essential, interviews would typically not be the most effective choice.
