FREE Certified Six Sigma Black Belt Assessment Questions and Answers
A team that looked into measures to lessen power outages came to the conclusion that there are only three possible causes of an outage: grid failure, local transformer failure, or local overload. They create a design that "fans out" utilizing the power outage as the handle of the fan after thoroughly examining the three events for potential causes, etc. Which method of problem resolution encapsulates these advancements the best?
A tree diagram starts with a central issue and spreads out to other issues until the central issue is resolved. The tree diagram facilitates the six sigma team's systematic transition from the general to the specific.
Total Quality Management (TQM) was created by a quality leader, who is:
TQM was discovered and used for product quality control in the 1920s. Feigenbaum made further modifications to this idea.
Which of the following best defines a team that includes people with various jobs or skill sets from several organizational divisions?
A cross-functional team is a collection of individuals with various functional skill sets that collaborate to achieve a single organizational goal.
Which of the following pairs of data measurements is used to calculate total variance in measurement system analysis?
MSA is a tool for calculating the degree of measurement system variance. To reduce measurement system variation, techniques for measuring measurement variance and process variance are used.
Which method aids in boosting process stability when a messy workstation is the variation cause?
A 5S can be utilized in six sigma to lessen waste. Lean sigma's 5S method assures tidy and efficient workstation arrangement. This contributes to the process's increased stability.
When the sampling technique utilized results in a discrepancy between the sample result and the population value, the discrepancy is known as
Bias is the term used in statistics to describe the discrepancy between the sample's results and the population as a whole.
Which of the following will most likely have an impact on how consumers perceive quality?
Typically, quality means going above and beyond for the client. The customer experience and his perception of quality will be improved by the service and repair policies following the purchase of the goods.
A six sigma team's process for creating a problem statement will help to
An issue is precisely described in a problem statement. A problem statement facilitates understanding of the issue or problem and enables team members to take charge of the solution process.
Which of the following tools should be used when there are several criteria and only one possible option?
Many concepts are compared to a reference concept using a Pugh matrix to determine their strengths and weaknesses. The base concept or datum is another name for the reference concept.
The data collector should be ethical, which is a crucial component of data collection.
To obtain accurate information on the desired area of interest, data collecting is a systematic way of obtaining data from numerous sources. Knowing where to obtain data and how to use it to produce the required results is a statistician's most crucial skill.
A technique that modifies data without significantly lowering precision or accuracy is referred to as
The process of coding involves classifying and putting quantitative and qualitative data into categories for analysis. Accuracy and precision are not decreased during the coding process.
Which of the following best describes the DPMO formula?
A metric used in lean six sigma to gauge process performance is defects per million opportunities (DPMO).
The defect-to-opportunity ratio (DPMO) is the ratio of opportunities to defects multiplied by one million.
SWOT is an abbreviation meaning
A SWOT analysis examines an organization's internal and external environments. Internal analysis identifies strengths and weaknesses, and external analysis identifies opportunities.
A method for illustrating the relationship between client wants and product attributes
A relationship matrix connects the what and the how. This matrix represents new business development. This matrix aids in establishing the connection between the features of the product and the needs of the consumer.
Which of the following should a change agent assist the organization with?
The black belt is frequently referred to as a "change agent." Change is challenging and unclear. The change agent aids organizations in overcoming their fear of the unknown.
The mean of a sample drawn at random from a population is not the same as the mean of the population. This is because:
The discrepancy between the population estimated by the sample and the actual population is what leads to sampling error. The observation of the sample rather than the entire population is what led to this inaccuracy.
