The correct answer is B. Cause and effect diagram . In the CSSBB body of knowledge, gap analysis identifies the difference between current and desired performance, but a team then needs a root-cause tool to determine why that gap exists. The cause and effect diagram , also called a fishbone or Ishikawa diagram, is specifically used to organize and explore potential causes of a problem so the team can identify likely source factors for further verification. The CSSBB material explains that teams brainstorm categories and possible causes in order to investigate root causes systematically. This makes it the most appropriate tool for identifying the source of a performance gap.

The other tools serve different purposes. A matrix diagram shows relationships among sets of items. An activity network diagram is used for scheduling and sequencing project activities. An affinity diagram groups ideas into natural clusters after brainstorming. None of those is primarily intended to identify root causes behind a gap in performance. Since the question asks for the tool to identify the source of the gap, the best CSSBB answer is the cause and effect diagram , which is designed for structured root-cause analysis.

The correct answer is Norming. In the norming stage of team development, members begin to work together more smoothly, relationships strengthen, trust increases, and the team develops a stronger sense of cohesion. Team members are generally satisfied with the group’s progress and feel more comfortable with one another. Roles become clearer, conflict is reduced or better managed, and collaboration becomes more natural. This contrasts with the forming stage, where members are still orienting themselves, and the storming stage, where disagreement and tension are more common as roles and priorities are tested. Performing is a later stage characterized by mature, highly effective, goal-focused teamwork, but the clue in this question is the emphasis on close attachments and growing satisfaction with progress, which is most characteristic of norming. In Six Sigma team management, understanding team-development stages helps Black Belts and facilitators provide the right support, especially when managing conflict, building commitment, and improving communication. Therefore, the correct answer is C, Norming, because it reflects a team that has developed cohesion and positive working relationships.

The correct answer is A. Increased flexibility . The CSSBB material on setup reduction and SMED explains that reducing setup times is one of the most important Lean tools because it expands production capacity , reduces inventory , and improves the organization’s ability to respond to changing requirements. It specifically notes that setup time reduction improves speed and flexibility .

This is the primary benefit because shorter changeovers allow smaller lot sizes, more frequent product changes, and faster response to customer demand without major production penalties. While better setups can indirectly help quality or throughput, the main Lean advantage of SMED is that the process becomes much more adaptable and responsive. Fewer defects and fewer breakdowns are more directly associated with other methods such as poka-yoke and total productive maintenance. Higher rolled throughput yield may improve indirectly if changeovers become smoother, but that is not the principal reason SMED is used. Therefore, from a CSSBB perspective, the best and verified answer is A. Increased flexibility .
