A data point on a control chart that requires investigation is called:
A. A special cause.
B. Gold plated.
C. A rule of seven.
D. A specification limit.
Answer: A
A data point that requires you to determine the cause of the problem calls for a special cause (choice A).
Gold plating (choice B) is providing the customer more that what they asked for. A rule of seven (choice C) is not just a single data point and thus not correct, even though it also requires an assignable (special) cause. A specification limit (choice D) indicates the customer-defined requirements for quality.

You are a project manager working on a project that requires 100 items to be tested, spaced evenly over five weeks. You have just begun week three, with an overall budget of US $10,000. To date, you have spent US
$2,000 with 40 items tested successfully. What does the cost variance (CV) tell you in this circumstance?
A. The project is proceeding at 100 percent of the expected rate.
B. The project is $2,000 under budget.
C. The project is on budget.
D. The project is getting $2 of work for every dollar spent.
Answer: B
EV is determined from a total budget of $10,000 and a five week duration. Each week would be $2,000.
Therefore, for two weeks of completed work, we have an EV of $4,000. CV = EV – AC, CV = $4000 – $2000 = $2,000. Positive means you are under budget.

As the project manager, you are preparing your methods for quality management. You are looking for a method that can demonstrate the relationship between events and their resulting effects. You want to use a method to depict the events that cause a negative effect on quality. Which of the following is the BEST choice for accomplishing your objective?
A. Histogram
B. Pareto chart
C. Ishikawa diagram
D. Control chart
Answer: C
All reports and diagrams are communications tools. This question asks you to pick the most appropriate quality tool to help communications. An Ishikawa diagram (choice C), also called a cause and effect diagram, is more appropriate than a Pareto chart (choice B) since you are trying to determine the causes. Once causes are known and you have data on occurrences, the data can be displayed in a Pareto chart.

If the probability of one event occurring does not affect the probability of another event occurring, the events are:
A. False events.
B. Mutually exclusive.
C. Statistically independent.
D. Just-in-time.
Answer: C
Choice A is not correct because the events are true events. Choice B is not correct because, by definition, two events that are mutually exclusive cannot happen on the same trial. Choice D is incorrect because justin- time refers to inventory levels. Choice C is correct because statistical independence refers to two events not being linked.

A project manager has been overwhelmed with problems on his project. He would like to identify the root cause of the problems in order to determine where to focus his attention. Which of the following tools would be BEST for the project manager to use?
A. A Pareto chart
B. Conflict resolution techniques
C. A fishbone diagram
D. Trend analysis
Answer: C
A Pareto chart (choice A) might help the project manager decide which problems to focus on, but does little to find the root cause of problems. Though the project is troubled, there is nothing on which to use conflict resolution techniques (choice B), because the real problem has not been identified. Trend analysis (choice D) does not deal with root causes; it deals more with predicting the future. The best choice is C.
