Q

What is marginal analysis?

A

An analysis to determine when optimal quality is reached, to determine the point where incremental benefits or revenue from improving quality equals the incremental cost to secure it.

Q

What is a normal distributing curve?

A

A symmetric bell-shaped frequency distribution curve used to measure variation
This is the most common probability distribution

19
Q

What does sigma signify in a process?

What is another name for sigma?

A

How much variance from the mean has been established as permissible in a process

Standrad deviation

20
Q

What do 3 sigma and 6 sigma refer to?

A

These are commonly used as quality standards

3 sigma: +/- 3 SD from the mean
6 sigma: +/- 6 SD from the mean

6 sigma is a higher quality SD than 3 sigma

21
Q

What is the difference between a population and a sample?

A

Population: The total number of individual members, items or elements comprising a uniquely defined group

Sample: A statistically valid subset of population members

22
Q

Who is responsible about the quality a project?

A

The project manager has the ultimate responsibility, plus the team should inspect their own work.

23
Q

What are the impacts of poor quality?

A
  • Increased cost
  • Decreased profits
  • Low morale
  • Low customer satisfaction
  • Increased risk
  • Rework
  • Schedule delays
24
Q

What are examples of costs of conformance and costs nonconformance?

A

costs of conformance:

  • Quality training
  • Studies
  • Surveys
  • Efforts to ensure everyone knows the processes to sue to complete their work.

costs of nonconformance:

  • Rework
  • Scrap
  • Inventory costs
  • Warranty costs
  • Lost business
25
Q

What are costs of nonconformance associated with?

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

A

Costs of nonconformance are associated with poor quality

The costs of conformance should be less than the cost of conformance.

26
Q

What are the seven basic quality tools (7QC)?

A
  1. Cause and effect diagram
  2. Flowchart
  3. checksheet
  4. Pareto diagram
  5. Histogram
  6. Control chart
  7. Scatter diagram
27
Q

What is 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.

28
Q

How does a checksheet differ from a quality checksheet?

A

Although a checksheet is a type of checklist, its primary purpose is to gather data.

The quality checklist is intended to help verify a required action has taken place or item has been included.

29
Q

What is the cause and effect diagram?

A

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

It is also called a fishbone or Ishikawa diagram.

30
Q

What does a flowchart show?

A

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

31
Q

What is a 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 problem.

32
Q

What does a scatter diagram show?

A

The relationship between two variables.

33
Q

What is a control chart?

A

A specialized trend chart that documents whether a measured process is in or out of statistical control.

34
Q

What are control limits?

A

The acceptable range of variations on a control chart.

35
Q

What are the specifications limits on a control chart?

A

The customer’s definition of acceptable product/service characteristics and tolerances.

36
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, or there are nonrandom data points.

There is a lack of consistency and predictability in the process

37
Q

What is the rule of seven and what does it signify?

A

Seven consecutive data points appearing on a control chart on one side of the mean.

The process is out of statistical control.

38
Q

What is an assignable cause/specific cause variation?

A

A data point (or set of data points) on a control chart indicates that the measured process is out of statistical control and that the cause(s) of the event must be investigated.

39
Q

Define benchmarking

A

Comparing your project to other projects to get ideas for improvement and to provide a benchmark for measuring quality performance.

40
Q

What is design of experiments?

A

A statistical method that allows you to experimentally change all of the important variables in a process to determine what combination will optimize over quality.

41
Q

What is statical sampling?

A

Inspecting by testing only part of a population.

42
Q

Define cost-benefit analysis.

A

Comparing the costs of an effort to the benefits of the effort.

43
Q

What are some of the tools and techniques used in the perform quality assurance process?

A
  • Plan quality management and control quality tools and techniques
  • Process analysis
  • Quality audits
  • Affinity diagram
  • Tree diagrams
  • Process decision program chart.
  • Interrelationship digraphs
  • Matrix diagrams
  • Prioritization matrices
  • Activity network diagrams
44
Q

What is quality audit?

A

Structured review of quality policies practices and procedures to ensure they are efficient and effective.

These audits often results in lessons learned for the organization
