Which feedback method is least likely to involve direct interaction with staff?

The method of feedback least likely to involve direct interaction with staff is customer satisfaction surveys. These surveys typically gather information from clients or patients regarding their experiences and perceptions without requiring real-time engagement or communication with laboratory staff. Participants can complete these surveys independently, often anonymously, and the data collected is analyzed afterward to assess services and identify areas for improvement.

In contrast, informal conversations and formal meetings both require direct exchanges of information, with staff actively participating in discussions. Similarly, problem analysis involves interaction with team members to dissect issues and collaboratively develop solutions. Customer satisfaction surveys stand apart as they focus primarily on compiling insights from external sources rather than facilitating direct dialogue with staff members.
