When eliciting requirements from a large set of potential users with limited time, which technique is the best choice?

Using a closed-ended questionnaire is the best choice when eliciting requirements from a large set of potential users who have limited time. This technique allows for efficient data collection from a broad audience while minimizing the time commitment required from each participant.

Closed-ended questionnaires typically consist of specific questions with predefined answer options, making it quicker for users to respond compared to open-ended formats. This method not only facilitates the collection of quantitative data but also enables the analysis of responses in a systematic way. The structured nature of closed-ended questions ensures that the information gathered is consistent and aligned with the objectives of the requirements elicitation process.

In scenarios where time is a factor, the ability to quickly analyze and summarize responses from a large group can greatly enhance the efficiency of the requirements gathering process. This approach provides valuable insights while respecting the limited availability of potential users, ultimately leading to more focused and relevant requirements for the project.
