Lean Software Development Module 01 Quiz Answers
Lean Principles Quiz Answers
Q1. In Lean software development, how can amplifying learning occur? (Select all that apply)
Correct Answers:
- The developers use short iterations.
- The developers choose technologies that force them to learn new skills.
Explanation: Lean encourages learning by using short iterations, allowing feedback loops to occur quickly, and selecting technologies that encourage the development of new skills.
Q2. How can waste arise in software development? (Select all that apply)
Correct Answers:
- There are product defects found late in the development.
- Developers work on rarely used product features.
Explanation: Waste arises when product defects are found late (which can be costly to fix) or when developers work on features that are not frequently used, thus wasting time and resources.
Q3. In Lean software development, what does the principle of “defer commitment” mean?
Correct Answer:
- Decisions are made after having enough information from considering the alternatives.
Explanation: “Defer commitment” in Lean means delaying decisions until you have sufficient information, which ensures that decisions are made with the best possible understanding of alternatives.
Q4. In Lean software development, what does the principle of “deliver fast” mean? (select 2 that apply)
Correct Answers:
- A simpler version of software product (an MVP – Minimum Viable Product) is developed first to reach the market rapidly.
- Iterations are short, so feedback is frequent, and product evolution is rapid.
Explanation: “Deliver fast” means quickly delivering a simplified version (MVP) of the product and using short iterations for fast feedback and continuous product improvement.
Q5. Which of the following align with the lean principle of “build quality in”? (select 2 that apply)
Correct Answers:
- The developers apply practices to avoid or quickly catch errors while making the software product.
- The developers refactor the source code to be simpler and easier to modify.
Explanation: Building quality in involves applying practices to avoid or catch errors early and refactoring code to improve its maintainability and simplicity.
Q6. In Lean software development, what does “optimize the whole” mean? (Select all that apply)
Correct Answers:
- The ability of a system to achieve its purpose depends on how well the parts work together, not just how well they perform individually.
- Rather than trying to optimize one part, look at the whole system for optimization opportunities.
Explanation: “Optimize the whole” focuses on improving the entire system’s performance rather than optimizing individual components in isolation.
Q7. Which of the following tools can help you find waste in a process?
Correct Answer:
- Value Stream Mapping
Explanation: Value Stream Mapping is a Lean tool used to visualize and analyze the flow of materials and information, helping identify waste in a process.
Q8. What are some of the tools to amplify learning? (Select all that apply)
Correct Answers:
- Set Based Development
- Iteration
- Daily Builds and Smoke Tests
Explanation: These practices support learning by allowing for multiple solutions to be explored (Set Based Development), using iterations to continuously improve, and ensuring that builds are frequently tested (Daily Builds and Smoke Tests).
Q9. How do you deliver fast (i.e reduce cycle time) without compromising the quality?
Correct Answer:
- Minimize the number of items in-process.
Explanation: By reducing the number of items in process, you avoid overloading the system, which improves flow and speeds up delivery without sacrificing quality.
Q10. “The Last Responsible Moment” is a tool for which Lean Software Principle?
Correct Answer:
- Defer Commitment
Explanation: “The Last Responsible Moment” refers to deferring decisions until the latest possible point to ensure they are made with the most information.
Q11. Lean helps increase productivity by:
Correct Answer:
- Reducing the amount of useless activity that our resources (the team members) are currently burdened with.
Explanation: Lean focuses on eliminating waste, particularly non-value-added activities, to improve productivity and efficiency.
Q12. Which practices waste time during software development? (Choose two)
Correct Answers:
- Delays in receiving work products.
- Weekly meetings that are held whether or not they are needed.
Explanation: Delays in receiving work products and unnecessary weekly meetings are common sources of wasted time in software development.
Lean Software Development Module 02 Quiz Answers
Kanban, Value Stream Mapping and Kaizen Quiz Answers
Q1. The 5 “Whys” to be considered during a Root Cause Analysis are…?
Correct Answer:
- Why, Why, Why, Why and Why
Explanation: The 5 Whys technique involves asking “Why” five times to drill down into the root cause of a problem.
Q2. What is the purpose of the Lean tool ‘Kaizen’?
Correct Answer:
- An improvement activity to create more value and remove waste.
Explanation: Kaizen focuses on continuous improvement by making incremental changes to processes that remove waste and create more value.
Q3. Which of the following can be used to do 5 Whys analysis?
Correct Answer:
- A fishbone diagram
Explanation: A fishbone diagram (also known as Ishikawa or cause-and-effect diagram) is often used in conjunction with the 5 Whys analysis to visualize and analyze root causes.
Q4. In Kanban, a developer pulls the next item to work on from the:
Correct Answer:
- Previous column on the board
Explanation: In Kanban, work is pulled by developers from the previous column once they finish their current task, respecting the flow and WIP (Work in Progress) limits.
Q5. You are a developer on a team using a Kanban board to manage flow. You work on Step X within the process, and it just so happens that you are looking for more work.
Correct Answers:
- Help the group (that picks work from the following column) finish their work so they can pull an item from the “Done” column of Step X. That will allow you to pick an item from the previous step.
Explanation: The correct action is to help ensure that work in the “Done” column is completed so that you can pull the next item according to the WIP limit.
Q6. Which of the following statements are true about Value Stream Mapping? Select all that apply.
Correct Answers:
- Cycle Time is the total time taken for Value Stream.
- Value-added activities are activities that add value from the customer perspective.
Explanation: Cycle time refers to the total time taken for the value stream, and value-added activities are those that directly contribute to customer value.
Q7. What is the formula to calculate the Process Cycle Efficiency?
Correct Answer:
- Value Added Time / Cycle Time
Explanation: Process Cycle Efficiency (PCE) is calculated as the ratio of value-added time to the total cycle time. This metric helps evaluate how efficiently time is spent on activities that add value.
