The PDCA cycle of quality improvement can be used for which of the following? Exploring a range of solutions to a problem and piloting them in a controlled way before selecting one for implementation Planning quality concurrently with production planning Working toward a decision that satisfies all participants Prioritizing changes by identifying the problems that will be resolved by making these changes

Exploring a range of solutions to a problem and piloting them in a controlled way before selecting one for implementation The PDCA (plan-do-check-action) cycle is a four-step process for quality improvement. In the first step (plan), a plan to effect improvement is developed. In the second step (do), the plan is carried out, preferably on a small scale. In the third step (check), the effects of the plan are observed. In the last step (action), the results are studied to determine what was learned and what can be predicted.

Warranty claims and repair costs fall into which of the following categories of quality costs? External failure Internal failure Prevention Appraisal

External failure

Which of the following statistical process control tools shows the extent and type of variation in a set of data? Flowchart Pareto chart Histogram Scatter plot

Histogram A histogram charts the type of variance as well as the frequency distribution.

What is the first step in the A3 process? Research the possible solutions. Identify the required outcome. Map out the follow-up process. Identify the root cause and importance of the issue.

Identify the root cause and importance of the issue.

A supplier develops a plan-do-check-action (PDCA) strategy to mitigate customer-reported manufacturing problems. What would the supplier's next step be? Implementing lean processes starting with five Ss projects Implementing quality processes such as statistical process control Encouraging more involvement by cost accounting directly with shop floor supervisors Hiring black-belt-certified associates to address the problem

Implementing quality processes such as statistical process control PDCA helps to identify a solution to the problems, but, once the solution is implemented, statistical process control methods would be used to monitor and control the process and ensure that it operates at its full potential.

Which of the following applies to the number of levels in a cause-and-effect diagram? Limited by the physical dimensions of the paper Limited by the number of causes and subcauses Limited by the length of the brainstorming session Limited to two to three based on a significant few principles

The defect information shown below has been collected for a welding assembly. The quality team uses a Pareto analysis to prioritize the individual decisions that will most improve the situation. Using the Pareto principle, which of these issues should be addressed first? Weld is broken plus weld is cracked plus weld seam not ground smooth Weld is broken plus weld is cracked plus weld seam not ground smooth plus seam incompletely welded Weld is broken Weld is broken plus weld is cracked

Weld is broken plus weld is cracked The Pareto principle, which was developed by Italian economist Vilfredo Pareto, states that a small percentage of a group accounts for the largest fraction of its impact or value. It is sometimes referred to as the 80/20 rule. In the case of a quality improvement process, that would mean that 20% of factors create 80% of the problems. In this case, a total of 74 defects are recorded, and weld is broken plus weld is cracked make up 65 of those 75 instances. Solving these two issues will eliminate just under 88% of the total defects.

When is 100% inspection most appropriate for an incoming part used in a complex product assembly? When the inspection cost is less than the cost of loss resulting from failure of the part When the high cost of inspection is justified by the high cost of the part itself When there is a high probability of one or more failures within the inspection batch When there is a high cost of failure to the customer in normal use of the product

When the inspection cost is less than the cost of loss resulting from failure of the part Inspection at 100% would be appropriate when the inspection cost is less than the cost of loss resulting from failure of the part.
