Question 72
Which of the following would be considered a barrier to empowerment?
Correct Answer: C
The correct answer is C. Providing information on a need-to-know basis . The CSSBB empowerment material defines empowerment as giving individuals the authority to make decisions, contribute ideas, exert influence, and be responsible. It also says management can erase barriers to empowerment by providing more support , providing training , acting as facilitators, and recognizing accomplishments. In addition, the empowerment progression chart explicitly includes information sharing as an important step toward awareness, support, commitment, and ownership. Because empowerment depends on people having enough information to understand the process, make decisions, and take initiative, limiting information to a narrow "need-to-know" basis works against empowerment. The other choices are supportive rather than restrictive. Rewarding learning, understanding motivation, and valuing team decision-making all encourage participation and ownership. Therefore, the factor that acts as a barrier is the one that withholds information and reduces the ability of employees to act independently. The verified CSSBB answer is C .
Question 73
In project management, a benefit-cost ratio is most commonly used to
Correct Answer: C
A benefit-cost ratio is most commonly used to prioritize projects by comparing the expected value of project benefits against the required investment. In organization-wide deployment, leaders often have more potential improvement projects than they can fund or staff, so they need a rational method for selecting which ones should proceed first. The benefit-cost ratio supports this decision by helping management compare alternatives on a relative value basis. Projects with stronger returns compared with their required costs are generally more attractive for selection, especially when resources are constrained. This ratio does not determine the actual cost of a project or calculate a project's true cost in an accounting sense. It also may inform resource decisions, but its primary use is project selection and prioritization. In a Six Sigma deployment, this aligns project choice with business impact, financial return, and strategic value. Black Belts and sponsors use these kinds of financial screening methods to ensure that the portfolio of projects supports organizational goals and produces measurable benefit. Therefore, the correct answer is C, prioritize projects.
Question 74
The primary purpose of a statistical process control chart is to
Correct Answer: B
The primary purpose of a statistical process control chart is to monitor a process and gain knowledge about its performance over time. In the CSSBB Control Phase, control charts are used to distinguish common-cause variation from special-cause variation so that the team and process owner can understand whether the process is stable and predictable. This understanding is essential before taking action. Control charts do not directly reduce variation by themselves; rather, they reveal process behavior so informed decisions can be made. They are also not mainly inspection tools for sorting conforming from nonconforming product. While they may help detect unusual conditions before defects are produced, their main function is process monitoring, not final product screening. Control charts support learning by showing trends, shifts, cycles, instability, and changes in variation, enabling the organization to respond appropriately to signals in the process. This is why SPC is a cornerstone of sustaining improvements after implementation. Therefore, the correct answer is monitor a process and gain knowledge about its performance, because that best captures the true purpose of a control chart in Six Sigma practice.
Question 75
When comparing two vendors' machines it is found that a sample of 1000 parts from machine A has 23 defectives and a sample of 1300 parts from machine B has 36 defectives. Do the data indicate that machine B has a higher rate of defectives?
