B) Lean is a set of principles for flow; DevOps adds cultural and tooling practices to enable that flow. C) Lean focuses on continuous delivery; DevOps focuses on agile planning. D) Lean requires no measurement, whereas DevOps relies on metrics. Answer: B
Exam
Explanation: Lean provides the philosophy of waste reduction and flow; DevOps builds on that with cultural change and automation to realize continuous delivery. Question 4. According to the Westrum model, a “generative” organization is characterized by: A) Strict hierarchy and fear of failure B) Low cooperation and high bureaucracy C) High cooperation, shared goals, and learning from failures D) No documentation standards Answer: C Explanation: Generative cultures promote cooperation, shared responsibility, and treat failures as learning opportunities. Question 5. The “You Build It, You Run It” model primarily reduces which anti‑pattern? A) Manual hand‑offs between development and operations B) Excessive test automation C) Frequent code merges D) Over‑documentation of requirements Answer: A Explanation: By giving developers ownership of operations, the model eliminates the siloed hand‑off that causes delays and miscommunication.

Exam
Explanation: Overproduction waste occurs when more is built than needed, such as unused features. Question 38. The “pull” principle in Lean IT encourages: A) Developers pushing code to production as soon as it is written B) Teams only starting work when there is capacity downstream to consume it C) Unlimited parallel work items in the pipeline D) Manual approvals for every change Answer: B Explanation: Pull means downstream demand triggers upstream work, preventing excess WIP. Question 39. Which practice most effectively reduces “batch size” in a delivery pipeline? A) Merging large feature branches once per month B) Deploying small, incremental changes multiple times a day C) Using monolithic architectures D) Performing manual regression testing after each release Answer: B Explanation: Small, frequent releases reduce batch size, lowering risk and improving feedback.
