The process that should take priority is the one related to the organization’s strategic plan. In Six Sigma deployment, project and process priorities should be driven first by strategic alignment. When an improvement effort directly supports the strategic plan, it is more likely to receive leadership sponsorship, funding, cross-functional support, and long-term attention. Strategic alignment also increases the chance that the improvement will produce meaningful business impact rather than only local optimization. The other characteristics listed may still matter. A process used in various areas of the organization may offer broad benefit, and a process that avoids delivery disruption may be easier to improve operationally. However, without strategic relevance, those efforts may not rank as highly in an enterprise deployment model. Black Belts are expected to connect improvement work to business priorities, not just convenience or operational spread. Therefore, the correct answer is C, Process C, because processes linked to the strategic plan should normally receive priority in organization-wide planning and deployment.

The correct answer is B. 1.20 . In ANOVA, the F statistic for a factor is calculated as the mean square for that factor divided by the mean square error . The CSSBB source presents ANOVA tables with columns for Mean Square and F , showing that the F value is formed from the factor mean square over the error mean square.

From the table:

Factor Y mean square = 9.0

Error mean square = 7.5

So:

F = 9.0 / 7.5 = 1.20

This matches option B . The degrees of freedom shown in the table help identify the correct reference distribution, but the computed F statistic itself is simply the ratio of the factor’s mean square to the error mean square. Since the model has no interaction term , only the factor mean squares and the pooled error term are used. Therefore, the verified CSSBB answer is 1.20 .

The correct answer is C. Improve . The CSSBB body of knowledge places DOE directly in the Improve phase; the instructor text lists “IX. Improve — DOE” as a major topic area. The supplemental material also explains that in the Improve Phase teams establish relationships between KPOV’s and KPIV’s , validate improvements, and use experimental methods to determine the settings of inputs that optimize the response.

DOE is a scientific method for making purposeful changes to factors and observing the effect on the response. That makes it especially useful when the team is trying to optimize a process or product after important variables have already been identified. While some supporting analysis of variables occurs earlier, the primary practical use of DOE in DMAIC is to test and confirm which factor settings improve performance. The supplemental source describes DOE as directed at optimization and as a way to learn how inputs affect outputs. Therefore, the best CSSBB answer is C. Improve .

The correct answer is A. A control plan . The CSSBB source states that the project control phase is necessary in order to sustain the project gains and that the control plan must remain a living document to monitor and control the process. It also says that a responsible person should be placed in charge of the control plan, and that the process owner is often the best person for that role. In the closing-phase guidance, the source specifically includes identifying the process owner , creating updated work instructions and procedures , training affected personnel , and attaining agreement between the team members and process owner .

These points directly support the idea of keeping the improved process in place and transferring ownership to those who will use and maintain it. A control chart is only one monitoring tool, not the full sustainment document. A process change order is an administrative record, and FMEA is a risk-analysis tool. Therefore, the document intended to sustain the gains, discourage tampering, and hand off responsibility is the control plan . The verified answer is A .

The best answer is D. needs breakthrough thinking . The CSSBB source describes the affinity diagram as an organized method to gather facts and ideas and form developed patterns of thought, especially in the planning stages of a problem. It is used when a team needs to make sense of many ideas, unclear information, or an unfamiliar problem. The broader creative problem-solving material also emphasizes the need to transcend ordinary thinking and pursue breakthrough approaches for more innovative solutions.

An affinity diagram is not the tool for handling a simple issue that one person can solve alone, nor is it the best immediate-response tool for a time-critical problem. It is also not a direct response to an outlier on a control chart, where statistical investigation would normally come first. Instead, it is valuable when the team needs to organize scattered thoughts, discover meaningful patterns, and move beyond obvious ideas. That is why, among the listed choices, the strongest CSSBB-aligned answer is D. needs breakthrough thinking .

The correct answer is B. 0.90 . In CSSBB hypothesis testing, the power of a test is defined as 1 − β , which is the probability of rejecting the null hypothesis when the null hypothesis is actually false. The CSSBB source explicitly states that 1 − β = Probability of rejecting the null hypothesis given that the null hypothesis is false . With β = 0.10 , the power is:

Power = 1 − 0.10 = 0.90

The same CSSBB supplemental material also explains that beta risk of 0.10 is normally associated with a power to detect of 90% , which confirms the calculation directly. Alpha, by contrast, is the risk of a Type I error, meaning rejecting a true null hypothesis. Although alpha and beta are related in test design, power is calculated specifically from beta, not from alpha. This concept is important in Six Sigma because Black Belts must ensure that hypothesis tests are sensitive enough to detect meaningful differences in process performance. Therefore, when α = 0.05 and β = 0.10, the verified power of the test is 0.90 .

The correct answer is D. reinforcing values that are important to the company . The CSSBB source states that the ultimate reason rewards and recognition are given is to provide positive reinforcement for good performance , with the expectation that the performance will be repeated in the future. This means recognition is not just about morale or compensation. Its deeper purpose is to reinforce the behaviors, results, and values the organization wants repeated.

The CSSBB material also says team members must commit to team values , and management supports the team process by reinforcing positive results . When recognition is aligned with company values such as teamwork, customer focus, data-based improvement, and collaboration, it strengthens the culture the organization is trying to build. By contrast, promoting competition among workgroups can damage teamwork, and focusing on a select group of employees misses the broader cultural purpose of recognition. Therefore, the best CSSBB-based answer is D. reinforcing values that are important to the company .

In a pull system, the exit rate is determined by customer demand. This is one of the defining principles of Lean flow and pull-based operations. Rather than producing according to forecasts, internal targets, or upstream schedules, a pull system authorizes production and movement based on what the downstream customer actually needs. This customer may be an external buyer or an internal downstream process. The output rate therefore matches demand consumption, helping prevent overproduction, excess inventory, waiting, and unnecessary work in process. Defect rates may affect usable output, but they do not define the intended exit rate. Work in process is an inventory condition within the system, not the driver of output pace. Productivity targets may be used for performance management, but in a true pull environment they do not override demand-based flow. For Black Belts working in Improve Phase process design, understanding this principle is essential when redesigning systems for flow, takt alignment, and inventory reduction. Therefore, the correct answer is B, customer demand, because pull systems are driven by downstream need rather than by push-based planning logic.

The correct answer is A. Publish an agenda . The CSSBB meeting-management material emphasizes that well-functioning teams establish an agenda and use it to create clarity about goals and content. Supporting facilitator guidance in the Lean Six Sigma materials states even more directly that the agenda is used by the facilitator to direct the flow of the meeting , make sure the meeting stays on track , ensure the goals of the meeting are achieved, and prevent time from being wasted.

A flip chart may help capture information, but it does not by itself control the schedule or focus. A project charter keeps the team aligned with the overall mission and scope, but it is broader than the structure needed for a single meeting. Brainstorming is a technique for idea generation and can actually consume time unless it is guided by a clear agenda. Because the question asks which tool would keep meetings focused and on schedule, the agenda is the most direct and effective answer. Therefore, the CSSBB-consistent choice is A. Publish an agenda .

In CSSBB team structure, the team leader is the role most directly responsible for maintaining task accountability among team members. The instructor material describes the leader as the person who provides direction, suggests assignments, handles administrative details, assesses group progress, and takes the steps necessary to ensure success. Those responsibilities align closely with tracking commitments and ensuring that assigned work gets completed. The sponsor provides higher-level support, resources, and strategic backing, but does not usually manage day-to-day task follow-through. The facilitator focuses more on team process, group dynamics, and helping the team function effectively rather than owning direct accountability for individual assignments. A coach mentors and develops capability, but is not the primary person managing task execution. In practice, the team leader converts the charter and plan into responsibilities, follows up on deadlines, coordinates dependencies, and escalates problems when needed. That makes the team leader the role that holds members accountable for completing assigned tasks. Therefore, the correct answer is Team leader.
