Answer 1

1. Errors or defects - # identified, fixed
2. Performance - reliability, size, accuracy, weight
3. Technical Performance - meet specs?

Question 2

This measure includes the source of defects, number of defects identified, and number of defects resolved.

Answer 2

Information on errors and defects

Question 3

These measures characterize physical or functional attributes relating to the system operation.

Answer 3

Measures of performance

Question 4

Size, weight, capacity, accuracy, reliability, efficiency, and similar performance measures are examples of what measure?

Answer 4

Measures of performance

Question 5

These quantifiable measures of technical performance are
used to ensure system components meet technical requirements.

Answer 5

Technical performance measures

Question 6

What provide insights into progress in achieving the technical solution?

Answer 6

Technical performance measures

Question 7

The ability of the system or its components to perform their intended function under specified conditions for a specified period of time is called?

Answer 7

Reliability

Question 8

The ratio of output to input, such as the amount of work accomplished per unit of time or per unit of energy consumed is called?

Answer 8

Efficiency

Question 9

The degree to which the system or its components conform to a standard or specification is called?

Answer 9

Accuracy

Question 10

The maximum amount of work that can be performed by the system or its components is called?

Answer 10

Capacity

Question 11

What measurements are associated with work in progress and are frequently
used in projects using adaptive approaches?

Answer 11

Delivery Measurements

Question 12

This measure indicates the number of work items that are being worked on at any given time. It is used to help the project team limit the number of items in progress to a manageable size.

Answer 12

Work in Progress

Question 13

This measure indicates the amount of elapsed time from a story or chunk of work entering the backlog to the end of the iteration or the release.

Answer 13

Lead Time

Question 14

What does a lower lead time indicate?

Answer 14

Lower lead time indicates a more effective process and a more productive project team.

Question 15

What indicates the amount of time it takes the project team to complete a task?

Answer 15

Cycle Time

Question 16

Shorter cycle times indicate

Answer 16

A more productive project team.

Question 17

What does a consistent cycle time indicate?

Answer 17

A consistent time helps predict the possible rate of work in the future.

Question 18

What measure tracks the number of items in a queue?

Answer 18

Queue Size

Question 19

What can the queue size be compared to?

Answer 19

the work in progress limit

Question 20

What states that when a system is running at maximum capacity, adding more work onto the system only slows it down?

Answer 20

Little’s Law

Work in Progress = Cycle Time X Throughput

More formally, Little’s Law states that cycle time equals work in progress divided by the system’s throughput.

Question 21

What is used to help understand the relationship between work in progress, cycle time, and throughput?

Answer 21

Little’s Law

Question 22

The rate at which work items are completed by the system.

Answer 22

Throughput

Question 24

What is used to help identify bottlenecks in a system and to optimize the flow of work through the system?

Answer 24

Little’s Law

Question 25

If the work in progress is high and the cycle time is also high, it may indicate that…

Answer 25

there are bottlenecks in the system that are slowing down the flow of work

Question 26

If the work in progress is high and the throughput is low, it may indicate that…

Answer 26

there are capacity constraints in the system that are preventing work from being completed at a faster rate.

Question 27

If the cycle time is high and the throughput is low, it may indicate that…

Answer 27

there are inefficiencies in the process that are slowing down the completion of work.

Question 28

What measures the estimated amount of work (level of effort, story points, etc.) that is expected to be completed in an iteration?

Answer 28

Batch Size

Question 29

What is a ratio used in lean systems to optimize the flow of work. This measure calculates the ratio between value-adding time and non-value-adding activities.

Answer 29

Process efficiency

PE = Value Adding Time (VAT) / (VAT+NVAT)

Question 30

Higher ratios of process efficiency indicate?

Answer 30

A more efficient process

Question 31

By measuring and improving process efficiency, organizations can optimize…

Answer 31

the flow of work and reduce waste, which can lead to improved productivity and customer satisfaction.

Question 32

Tasks that are waiting increase the…

Answer 32

Non-Value Add Time

Question 33

tasks that are in development or in verification represent

Answer 33

Value Add Time
