Q

What is statistical independence?

A

The probability of one event occurring does not affect the probability of another event occurring (for example, the probability of rolling a six on a die is statistically independent from the probability of getting a five on the next roll)

Q

What does a logical data model represent?

A

The types of data an organization needs to use in a particular application, and the relationships between those data types

23
Q

What does a flowchart show?

A

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

24
Q

What is the purpose of test and inspection planning?

A

How the team will confirm that the required level of quality has been achieved in the completed project deliverables, and how the deliverables will be evaluated for performance and reliability

25
What is the purpose of marginal analysis?
Finding the point at which the benefits or revenue to be received from improving quality equals the cost to achieve it
26
What is a prioritization matrix used for?
To numerically rank available options It is useful for decision analysis about quality management planning
27
What are some of the methods used in the Manage Quality process?
Checklists Cause-and-effect diagrams Histograms Scatter diagrams Document analysis Alternatives analysis Design of experiments (DOE) Process analysis Root cause analysis Failure analysis Multicriteria decision analysis Flowcharts Affinity diagrams Audits Design for X Problem-solving
28
What is a cause-and-effect diagram?
A graphical tool used to confirm that policies and procedures are being followed and metrics are being used correctly, and that the procedures were adequate to produce the required level of quality in project deliverables It is also called a fishbone, Ishikawa, or why-why diagram
29
What is design of experiments?
A technique used to quickly discover optimal conditions in which to produce a quality deliverable
30
What is process analysis?
As part of the continuous improvement effort, it focuses on identifying improvements that might be needed in project processes
31
What is the purpose of failure analysis?
It analyzes failed components of deliverables, or failed processes to determine what led to that failure
32
What is design for X used for?
Analyzing variables to evaluate both the effectiveness of the quality management plan and the team’s ability to meet objectives It can help determine what changes are needed
33
Name some Control Quality methods.
Checklists Statistical sampling Questionnaires and surveys Performance reviews Root cause analysis Inspection Control charts Cause-and-effect diagrams Histograms and Pareto charts Check-sheets Scatter diagrams
34
How does a check-sheet differ from a quality checklist?
Although a check-sheet is a type of checklist, its 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
35
What is statistical sampling?
Inspecting by testing only part of a population
36
What is a control chart?
Control charts are used in Control Quality to help determine if the results of a process are within acceptable limits
37
What do specification limits represent on a control chart?
The customer’s expectations or contractual requirements for performance and quality on the project
38
What is a mean on a control chart?
The average—the middle of the range of acceptable variation
39
How is a process defined as statistically out of control?
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
40
What does out of control mean?
There is a lack of consistency and predictability in the process or its results
41
What is the rule of seven? What does it signify?
A group or series of nonrandom data points that total seven on one side of the mean The rule of seven indicates that, although none of these points are outside of the control limits, they are not random and the process is out of control
42
What is an assignable cause/special cause variation?
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
43
What is a Pareto chart?
A histogram that arranges the results from most frequent to least frequent to help identify which issues are resulting in the most problems
44
What is a scatter diagram used for?
It is used to compare actual results to what was anticipated, and to estimate and forecast future outcomes based on this comparison
45
What term describes how discovering quality issues early may decrease cost and rework that can impact a project?
Cost of change
46
On agile and hybrid projects, how does getting feedback on small increments of work as soon as possible help the project manager evaluate when there is an issue with quality?
Learning about quality issues early, when they are usually still small and minor, allows them to be corrected while they are still low on the cost of change curve
47
What is frequent verification and validation?
Regular testing, short time-boxes, and reviews to meet the customer’s needs Used by agile teams as a way to discover and address human error or the misinterpretation of customer expectations, early and often
48
What is a retrospective?
A meeting that may be held after a release, or even the entire project Most often refers to the meeting that is held at the end of each short, time-boxed iteration of product development
49
What is the difference between lead time and cycle time?
Lead time measures how long something takes to go through an entire process Cycle time measures how long something takes to go through just a part of the process
50
Define WIP and throughput.
WIP (Work in Progress) is the number of unfinished pieces of work going on at one time Throughput is average time it takes to complete the work
51
How can WIP and throughput be used to calculate cycle time?
Cycle time is a function of WIP and throughput and can be calculated by using the formula: cycle time = WIP/throughput
52
What is defect cycle time?
Defect cycle time is the amount of time between the time the defect was introduced and the time it was fixed.
53
Why is it important to create a safe and open environment?
Creating a safe and open environment will help the project team feel comfortable not just to do their work but to admit their problems, failures, and mistakes and ask for help so that the project can stay on track and save time and money
