Question 1

What is the central argument of Accelerate regarding software delivery?

Answer 1

High performance in software delivery is not traded off against stability; rather, speed and stability enable each other and drive organizational performance. (Chapter 2, Pages 53, 58-59)

Question 2

What are the four key metrics identified to measure software delivery performance?

Answer 2

1. Lead Time for Changes, 2. Deployment Frequency, 3. Time to Restore Service (MTTR), 4. Change Failure Rate. (Chapter 2, Pages 47-51)

Question 3

According to the research, is there a trade-off between throughput (speed) and stability in software delivery?

Answer 3

No. High performers consistently demonstrate both higher throughput and better stability compared to low performers. They move in tandem. (Chapter 2, Pages 53, 254)

Question 4

What organizational outcomes does high software delivery performance predict?

Answer 4

Higher profitability, productivity, market share, and achievement of noncommercial goals (e.g., efficiency, effectiveness, customer satisfaction). (Chapter 2, Pages 58-59, 253)

Question 5

What is the Westrum model of organizational culture, and what are its three types?

Answer 5

A model describing how information flows within an organization, indicative of its culture. Types: Pathological (power-oriented), Bureaucratic (rule-oriented), and Generative (performance-oriented). (Chapter 3, Pages 64-66)

Question 6

Which type of Westrum organizational culture is predictive of high software delivery and organizational performance?

Answer 6

Generative (performance-oriented) culture, characterized by high cooperation, shared risks, bridging encouraged, inquiry from failures, and novelty implemented. (Chapter 3, Pages 71, 250)

Question 7

Can organizational culture be changed? If so, how?

Answer 7

Yes. Culture can be influenced and improved by changing practices. Implementing technical (like Continuous Delivery) and Lean management practices drives cultural improvements towards a generative model. (Chapter 3, Page 74)

Question 8

What is Continuous Delivery (CD)?

Answer 8

A set of capabilities enabling changes of all kinds (features, config changes, bug fixes, experiments) to get into production or users’ hands safely, quickly, and sustainably. (Chapter 4, Page 77)

Question 9

What are the five key principles of Continuous Delivery?

Answer 9

1. Build quality in. 2. Work in small batches. 3. Computers perform repetitive tasks, people solve problems. 4. Relentlessly pursue continuous improvement. 5. Everyone is responsible. (Chapter 4, Pages 77-78)

Question 10

What are the foundational technical practices required for Continuous Delivery?

Answer 10

1. Comprehensive configuration management. 2. Continuous Integration (CI). 3. Continuous Testing. (Chapter 4, Pages 79-80)

Question 11

What is the impact of Continuous Delivery practices on teams and performance?

Answer 11

CD practices drive higher software delivery performance, better organizational culture, lower burnout, and less deployment pain. (Chapter 4, Pages 81-85, 246)

Question 12

What is Trunk-Based Development, and how does it relate to performance?

Answer 12

A practice involving fewer than three active branches, short branch lifetimes (<1 day), and no code freezes/stabilization periods. It’s a predictor of high delivery performance. (Chapter 4, Pages 91-92, 245)

Question 13

Why is version control for all production artifacts (including configuration) important?

Answer 13

It’s a key component of CD. The research found that version controlling system and application configuration was even more highly correlated with performance than version controlling application code. (Chapter 4, Page 89, 245)

Question 14

What characterizes effective test automation suites according to the research?

Answer 14

They are reliable (pass means releasable, fail means real defect), primarily created/maintained by developers, and run regularly (fast feedback on commit, comprehensive feedback daily). (Chapter 4, Pages 89-90, 246)

Question 15

What architectural characteristic is the biggest driver of Continuous Delivery and IT performance?

Answer 15

A loosely coupled, well-encapsulated architecture, enabling teams to independently test and deploy their components/services. (Chapter 5, Pages 97, 258)

Question 16

What is Conway’s Law and the ‘Inverse Conway Maneuver’?

Answer 16

Conway’s Law: Org structure constrains system design. Inverse Conway Maneuver: Evolve your team/org structure to achieve the desired architecture (enabling loosely coupled teams/systems). (Chapter 5, Page 98)

Question 17

How does architecture affect an organization’s ability to scale its development teams?

Answer 17

Loosely coupled architecture allows organizations to add more developers and increase productivity linearly or better (measured by deploys/day/developer), unlike low performers where productivity decreases. (Chapter 5, Pages 100-101)

Question 18

Should teams be allowed to choose their own tools?

Answer 18

Yes. Allowing teams to choose tools contributes positively to continuous delivery and performance. Focus should be on outcomes and enabling engineers, not mandating specific tools unless they provide clear value and ease-of-use. (Chapter 5, Pages 102-104, 247)

Question 19

What does ‘Shifting Left on Security’ mean?

Answer 19

Integrating information security into the entire software delivery lifecycle (from design through testing and deployment), rather than treating it as a separate, downstream phase. (Chapter 6, Page 106, 246)

Question 20

How does integrating information security impact performance?

Answer 20

It improves continuous delivery capabilities and software delivery performance, and high performers spend significantly less time remediating security issues. (Chapter 6, Pages 106, 108)

Question 21

What are the key components of Lean Management practices for software delivery identified in the research?

Answer 21

1. Limiting Work In Progress (WIP). 2. Visual Management (displaying key metrics/work status). 3. Feedback from Production (using monitoring data for decisions). (Chapter 7, Page 112, 249)

Question 22

Do WIP limits alone predict performance?

Answer 22

No. WIP limits are effective only when combined with visual management and feedback loops from production monitoring to drive process improvement. (Chapter 7, Page 113)

Question 23

What did the research find about formal change approval processes (e.g., CABs)?

Answer 23

External approval bodies (like CABs) negatively correlate with delivery performance (slow down delivery without improving stability). Peer review-based approaches yield higher performance. (Chapter 7, Pages 115, 249)

Question 24

How can Segregation of Duties be achieved without a CAB?

Answer 24

Through peer review (recorded in VCS/deployment tools) and fully automated deployment pipelines that provide an audit trail. (Chapter 7, Page 116)

Question 25

What are the core practices of Lean Product Development?

Answer 25

1. Working in small batches (MVPs). 2. Making flow of work visible. 3. Gathering and implementing customer feedback frequently. 4. Enabling team experimentation and authority. (Chapter 8, Page 119, 248)

Question 26

What is the relationship between Lean Product Development and Software Delivery Performance?

Answer 26

It's a virtuous cycle: Better delivery performance enables Lean product practices (like small batches, user research), and Lean product practices predict better delivery performance and organizational outcomes. (Chapter 8, Pages 122-123)

Question 27

What is 'deployment pain', and what does it indicate?

Answer 27

The fear and anxiety engineers feel when deploying code. High deployment pain correlates with lower delivery performance, poorer organizational performance, and worse culture. (Chapter 9, Pages 125, 128, 256)

Question 28

What reduces deployment pain?

Answer 28

Implementing technical practices like comprehensive test/deployment automation, CI/CD, trunk-based development, version control of everything, loosely coupled architectures, and shifting left on security. (Chapter 9, Pages 127-128)

Question 29

What is burnout, and what organizational factors are highly correlated with it?

Answer 29

Physical, mental, or emotional exhaustion. Key correlated factors: 1. Organizational culture (pathological), 2. Deployment pain, 3. Ineffective leaders, 4. Lack of organizational investment in DevOps, 5. Poor organizational performance. (Chapter 9, Pages 130, 134, 256)

Question 30

How can organizations reduce burnout?

Answer 30

Foster a supportive (generative) culture, reduce deployment pain, develop effective leaders, invest in DevOps skills/tools, give employees control and resources, ensure values alignment. (Chapter 9, Pages 133-136)

Question 31

What is Employee Net Promoter Score (eNPS)?

Answer 31

A measure of employee loyalty, asking how likely an employee is to recommend their organization/team as a place to work. (Chapter 10, Pages 139-140)

Question 32

How does eNPS relate to performance?

Answer 32

High-performing organizations have significantly higher eNPS (2.2x more likely to recommend org). eNPS correlates with better business outcomes. (Chapter 10, Page 140, 260)

Question 33

What is 'Identity' in the context of employee engagement?

Answer 33

The extent to which employees identify with their organization's values and goals, feel the organization cares about them, and are willing to put in extra effort. (Chapter 10, Page 143)

Question 34

How do technical and Lean practices impact employee identity and job satisfaction?

Answer 34

They positively impact both. Better practices lead to stronger identity and higher job satisfaction, which in turn drives organizational performance. (Chapter 10, Pages 142, 146, 259)

Question 35

What is Transformational Leadership?

Answer 35

A leadership style where leaders inspire and motivate followers by appealing to values/purpose, challenging thinking, providing support, communicating vision, and offering personal recognition. (Chapter 11, Pages 157-158)

Question 36

What are the five characteristics of Transformational Leadership measured in the research?

Answer 36

1. Vision, 2. Inspirational communication, 3. Intellectual stimulation, 4. Supportive leadership, 5. Personal recognition. (Chapter 11, Page 157, 251)

Question 37

How does transformational leadership impact performance?

Answer 37

It is highly correlated with software delivery performance and employee Net Promoter Score (eNPS). It enables technical and Lean practices but doesn't guarantee high performance on its own. (Chapter 11, Pages 160-161, 261)

Question 38

What is the difference between Primary and Secondary research?

Answer 38

Primary research involves collecting new data (like the Accelerate surveys). Secondary research uses existing data collected by others. (Chapter 12, Pages 170-171)

Question 39

What is the difference between Qualitative and Quantitative research?

Answer 39

Qualitative research uses non-numerical data (interviews, observations). Quantitative research uses numerical data (system logs, survey scales). Accelerate uses quantitative survey data. (Chapter 12, Pages 171-172)

Question 40

What is the difference between Correlation and Causation/Prediction?

Answer 40

Correlation shows if two variables move together. Causation/Prediction (specifically inferential prediction in Accelerate) tests if one variable *drives* or *impacts* another, based on theory. (Chapter 12, Pages 176, 178)

Question 41

What are Latent Constructs in survey research?

Answer 41

Measures for things that cannot be observed directly (like culture or job satisfaction), captured using multiple related survey items (manifest variables). (Chapter 13, Page 186)

Question 42

How do latent constructs help ensure data quality?

Answer 42

1. Force careful definition of what's being measured. 2. Provide multiple views into the concept. 3. Make it harder for single bad data points or actors to skew results. (Chapter 13, Pages 188-189, 192)

Question 43

What are validity and reliability in psychometrics?

Answer 43

Validity: Does the measure capture what it's intended to capture? (Convergent: items group together; Discriminant: unrelated items don't). Reliability: Is the measure consistent? (Internal consistency: items interpreted similarly). (Chapter 13, Pages 191, 68)

Question 44

Why use surveys instead of relying solely on system/toolchain data?

Answer 44

1. Speed/Ease (esp. across orgs). 2. System data often incomplete/doesn't cover full stack. 3. System data doesn't capture context outside system boundaries. 4. Some things (perceptions, culture, specific practices) *only* measurable via survey. 5. Well-designed surveys can be trustworthy. (Chapter 14, Pages 197-208)

Question 45

What is Snowball Sampling, and why was it used for the State of DevOps research?

Answer 45

A non-probability sampling method where initial participants refer others. Used because the target population (DevOps practitioners) is hard to define exhaustively and can be averse to being studied. (Chapter 15, Pages 213-214)

Question 46

What is an Obeya room, as used in the ING case study?

Answer 46

A dedicated visual management room ('big room') where a leader's or team's work, priorities, performance, and problems are visualized to facilitate communication, alignment, and problem-solving. (Chapter 16, Page 222)

Question 47

What is 'catchball' as described in the ING case study?

Answer 47

A practice of vertical and horizontal communication for sharing learning and resolving problems, often involving tossing ideas/problems back and forth between levels or teams until resolved/refined. (Chapter 16, Page 227)

Question 48

What is the key takeaway from the ING case study regarding transformation?

Answer 48

High-performance culture is developed through experimentation and learning guided by evidence, adapting practices to the specific context. It requires leader commitment, coaching, discipline, and changing behaviors/mindsets, not just copying others. (Chapter 16, Pages 231, 234, 236)

Question 49

What is the first capability listed under Continuous Delivery in Appendix A?

Answer 49

Use version control for all production artifacts. (Appendix A, Page 245)

Question 50

Which capability focuses on slicing work into small pieces completed in less than a week?

Answer 50

Work in small batches. (Appendix A, Page 248)
