The Six Sigma project meeting attendees raised questions and concerns that would require additional discussion...

The correct answer is A. A parking lot . The CSSBB-aligned facilitation material explains that during meetings the facilitator can use the team charter, agenda, ground rules, and the bank or parking lot to prevent problems and improve efficiency. It specifically states that the bank or parking lot is used for items not on the current agenda , which are captured on a separate sheet and included in future agendas.

That is exactly what is needed in this situation. The attendees have raised valid questions and concerns, but addressing them immediately would require more time than the meeting allows. A parking lot preserves those issues without losing them and helps the facilitator keep the current meeting focused and on schedule. Ground rules manage behavior, a longer agenda would not solve the immediate time-management issue, and extra paperwork would not provide a structured follow-up mechanism. Therefore, the best CSSBB-based answer is A. A parking lot .
