Q

How does quality differ from grade?

A

Whereas quality is the degree to which a project (or deliverable) fulfills requirements, grade refers to a general category or classification of a deliverable or resource that indicates common function, but varying technical specifications

Q

What are examples of costs of conformance and costs of nonconformance?

A

Costs of conformance:
• Quality training
• Studies
• Measuring quality of interim deliverables
• Surveys
• Efforts to ensure everyone knows the processes to use to complete their work

Costs of nonconformance:
• Rework
• Scrap
• Inventory costs
• Warranty costs
• Lost business

17
Q

What are costs of nonconformance associated with?

Which should be greater, the costs of conformance or nonconformance?

A

Costs of nonconfromance are associated with poor quality

the costs of conformance should be less than the costs of nonconformance

18
Q

What is marginal analysis?

A

An analysis focused on finding the point at which the benefits or revenue to be received from improving quality equals the incremental cost to achieve that quality

19
Q

What is a logical data model?

A

It contains a description of the quality needs of the project and is used to understand the requirements, clarify business rules, and define processes

20
Q

What does a flowchart show?

A

How a process or system flows from beginning to end, how the elements interrelate, alternative paths the process can take, and how the process translates inputs into outputs

21
Q

What is the purpose of test and inspection planning?

A

For the team to determine how it will confirm that the required level of quality has been achieved in the completion of project deliverables, and how the deliverable will be evaluated for performance and reliability

22
Q

What are quality metrics?

A

Specific measures of quality that the project manager uses to determine how the project is performing

23
Q

What are some of the tools and techniques used in the Manage Quality process?

A 
Checklists
Cause-and-effect diagrams
Histograms
Scatter diagrams
Document analysis
Alternatives analysis
Process analysis
Root cause analysis
Multicriteria decision analysis
Flowcharts
Affinity diagrams
Audits
Design for X
Problem-solving
24
Q

What is design of experiments?

A

A technique that allows you to systematically change the important factors in a process and see which combinations have an optimal impace on the project deliverables

25
Q

What is the purpose of failure analysis?

A

It analyzes failed components of deliverables, or failed processes to determine what led to that failure

26
Q

What does mutual exclusivity mean?

A

Two events are said to be mutually exclusive if they cannot both occur in a single trial (for example, flipping a coin once cannot result in both a head and a tail)

27
Q

In what form is probability usually expressed?

A

As a decimal or a fraction

28
Q

What is a normal distribution curve?

A

A bell-shaped frequency distribution curve used to measure variation

This is the most common probability density distribution chart

29
Q

What is statistical independence?

A

The probability of event “B” occurring does not depend on event “A” occurring (for example, the probability of getting a five on the next roll)

30
Q

What does sigma signify in a process?

What’s another name for sigma?

A

It is a measure of how far you are from the mean (not the median)

Standard deviation

31
Q

Name some Control Quality tools and techniques.

A 
Checklists and checksheets Statistical sampling
Statistical sampling
Questionnaires and surveys
Performance reviews
Root cause analysis
Inspection
Control charts
Cause-and-effect diagrams
Histograms
Scatter diagrams
Meetings
32
Q

What is a quality checklist?

A

A list of items to inspect, a list of steps to perform, or a picture of an item to be inspected, with space to note any defects found

33
Q

How does a checksheet differ from a quality checklist?

A

Although a checksheet is a type of checklist, it’s primary purpose is to keep track of data

In Control Quality, checklists are used to determine that all required features and functions are included, and that they meet acceptance criteria

34
Q

What is statistical sampling?

A

Inspecting by testing only part of a population (a statistically valid sample)

35
Q

What is a control chart?

What are control limits?

A

Control charts are used in Control Quality to help determine if the results of a process are within acceptable limits

Control limits are the acceptable range of variation on a control chart

36
Q

What are the specification limits on a control chart?

What is a mean on a control charts?

A

Specification: The customer’s expectations or contractual requirements for performance and quality on the project

Mean: The average, the middle of the range of acceptable variation

37
Q

How do we define a process as statistically out of control?

What does out of control mean?

A

A data point falls outside the upper or lower control limit

There are nonrandom data points; these may be within the upper and lower control limits

38
Q

What is the rule of seven?

What does it signify?

A

It refers to a group or series of nonrandom data points that total seven on one side of the mean

The rule of seven tells you that, although none of these points are outside of the control limits, they are not random and the process is out of control

39
Q

What is an assignable cause/special cause variation?

A

An assignable cause or special cause variation signifies that a process is out of control

If there is an assignable cause or special cause variation, it means a data point, or a series of data points, requires investigation to determine the cause of the variation

40
Q

What is a cause-and-effect diagram?

A

A graphical tool that helps determine the possible root causes of a problem

It is also called a fishbone, Ishikawa, or why-why diagram

41
Q

What is Pareto chart?

A

A histogram that arranges the results from most frequent to least frequent to help identify which root causes are resulting in the most problems

42
Q

What does a scatter diagram show?

A

The relationship between two variables and the quality of the results
