20+ practice questions focused on Foundations OF Lean — one of the most tested topics on the Disciplined Agile Foundations (DAF, PMI-authorized, replaces the retired DASM) (DAF) exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Foundations OF Lean PracticeYou observe that a team often waits for external approvals, causing significant lead time delays. How should you apply Lean thinking to mitigate this?
Explanation: Lean thinking seeks to eliminate waste, particularly waiting. Delegating approval authority to the team for routine tasks removes a bottleneck and reduces lead time. This empowers the team and aligns with Lean principles of decentralized decision-making.
A Disciplined Agile team notices that their work items regularly wait in a 'Ready for Testing' queue for several days before a tester becomes available. The team has already reduced their work-in-progress limits. According to Lean principles, which action best addresses the root cause of this delay?
Explanation: The delay is caused by a handoff to a specialized tester, creating a queue. Lean thinking emphasizes eliminating waste such as waiting and handoffs. Cross-training developers to test removes that dependency and allows work to flow continuously, addressing the root cause rather than just the symptom.
A value stream map shows that a software feature spends 18 days in queues waiting for a specialist, but only 2 days of actual work is performed. The team wants to improve flow by reducing the time work waits. Which Lean concept should they apply first?
Explanation: Little's Law provides the mathematical relationship between WIP, throughput, and lead time, making it the right first tool when queues dominate. By measuring WIP and throughput, the team can predict how much lead time will drop if they limit WIP or increase throughput, directly attacking the 18-day wait.
What is the primary Lean goal of reducing the number of handoffs between specialized teams?
Explanation: In Lean, handoffs between specialized teams are a form of waste (specifically, waiting and defects from miscommunication). Each handoff introduces a queue, a transfer of tacit knowledge, and an opportunity for requirements or context to be lost. Reducing handoffs directly shrinks the opportunity for information loss and idle waiting time, which shortens lead time and improves flow.
Which of the following is considered 'Waste' (Muda) in a software development process?
Explanation: In lean/Disciplined Agile thinking, waste (Muda) is any activity that consumes resources without creating value for the customer. Developing features the customer will never use is the canonical example of 'extra features' waste (overproduction), because the effort, code, and maintenance burden deliver zero customer value. Eliminating it via prioritization, MVP thinking, and validated learning is a core DA principle.

Practice all Foundations OF Lean questions1. Baseline your knowledge
Start with 10 questions to gauge your current understanding of Foundations OF Lean. This tells you whether you need a concept refresher or just practice.
2. Review every explanation
For each question — right or wrong — read the full explanation. Understanding why an answer is correct is more valuable than knowing the answer itself.
3. Focus on exam traps
Foundations OF Lean questions on the DAF frequently use trap wording. Look for subtle differences in answers that test your precision, not just general knowledge.
4. Reach 80% consistently
Do repeated sessions until you score 80%+ three times in a row. Then move to mixed-mode practice to test cross-topic recall under realistic conditions.
The exact number varies per candidate. Foundations OF Lean is tested as part of the Disciplined Agile Foundations (DAF, PMI-authorized, replaces the retired DASM) (DAF) blueprint. Practicing with targeted Foundations OF Lean questions ensures you can handle any format or difficulty that appears.
