What method is most appropriate for obtaining suggestions on a change to a production method from affected individuals working in one factory?

Using a focus group to obtain suggestions on changes to a production method from affected individuals is highly effective because it encourages open discussion and collaboration among participants. In a focus group setting, individuals can share their experiences, ideas, and suggestions in a group environment, which can lead to a richer exchange of thoughts and diverse perspectives. This dynamic allows for the exploration of ideas in-depth, where one person's suggestion can spur additional thoughts from others, creating a comprehensive dialogue that may reveal insights which might not surface in individual settings.

Additionally, focus groups can foster a sense of team involvement, as participants see their peers engaging and contributing, which may encourage them to share their thoughts as well. This is particularly important in a factory setting where collaboration and team dynamics can significantly impact production changes.

In contrast, a survey may limit responses to what is structured in the questions, potentially missing out on nuanced insights. One-on-one interviews could provide detailed information but lack the collaborative brainstorming aspect and may be time-consuming. Observation may provide information on existing practices but does not actively solicit suggestions for changes directly from the workers involved.
