Answer

The Command lifecycle

Answer

The Waterfall lifecycle

Answer

The Static lifecycle

Question 2

Which of the following is NOT an objective of the 'Improve Process' goal?

Accepted Answer

Documenting every single step for auditors. Stopping the work to document everything is not an improvement strategy; it's a bottleneck.

Answer

Experimenting with new practices

Answer

Identifying process bottlenecks

Answer

Learning from past mistakes

Question 3

When a team is using a 'Kanban' system, what is the best way to determine if WIP limits are too high?

Accepted Answer

The cycle time is increasing while throughput remains stable.. If the cycle time is consistently increasing despite the throughput remaining the same, the WIP is likely too high.

Answer

The board looks too crowded.

Answer

The team is having too many meetings.

Answer

The team members are complaining about stress.

Question 4

You are trying to improve flow in a cross-functional team. How does 'T-shaped' skill development support this?

Accepted Answer

It enables team members to help each other, preventing bottlenecks.. T-shaped skills allow team members to jump in and help others during bottlenecks, preventing work from stalling.

Answer

It reduces the need for salary increases.

Answer

It increases the number of people available for specialized tasks.

Answer

It makes documentation unnecessary.

Question 5

Why does Lean emphasize 'Visible Management' for project boards?

Accepted Answer

It provides transparency that highlights issues without needing meetings.. Visible boards (like Kanban) allow everyone to see the status of the project, identifying bottlenecks and issues without needing a meeting.

Answer

It ensures the project looks good for visiting clients.

Answer

It is required by the PMO software.

Answer

It makes it easier for managers to track employees.

Question 6

A team has high 'wait time' between code completion and code review. How should they address this using Lean principles?

Accepted Answer

Incorporate code review into the 'In Progress' workflow state.. The team should pull the review into their workflow, making it a collaborative, immediate step rather than an external dependency.

Answer

Hire more senior developers to review code.

Answer

Eliminate code reviews.

Answer

Schedule all reviews for the end of the week.

Question 7

When applying the principle of 'Optimize the Whole', how should you view a 'specialized' sub-team?

Accepted Answer

As a potential silo that should be integrated into cross-functional flow.. Specialized teams often act as silos. The goal is to integrate them into a cross-functional unit to improve end-to-end flow.

Answer

As the most important part of the organization.

Answer

As a group that should work at their own pace.

Answer

As a highly efficient unit that should be kept separate.

Question 8

Which THREE of the following are considered 'Waste' in the context of Lean software development?

Accepted Answer

Waiting for external dependencies to clear.. Waste includes anything that does not add direct value to the end customer (e.g., waiting, rework, unused features).

Answer

Automated regression testing.

Answer

Pair programming sessions.

Question 9

You are identifying 'non-value-add' work in your process. What is the most important first step?

Accepted Answer

Create a current-state Value Stream Map.. Before you can eliminate waste, you must visualize the current state to know what is actually happening.

Answer

Hire an outside consultant to audit the process.

Answer

Immediately delete all documentation.

Answer

Interview every team member about their tasks.

Question 10

Which THREE of the following are foundational Lean thinking principles?

Accepted Answer

Elimination of waste.. Core principles include respect for people, continuous improvement, and the elimination of waste.

Answer

Mandatory 12-hour work days.

Answer

Centralized, hierarchical decision-making.

Question 11

Which TWO of the following are common types of 'Waste' (Muda) that teams should look for?

Accepted Answer

Waiting for information or approvals.. Lean defines several categories of waste, including waiting and motion.

Answer

Collaborative code reviews.

Answer

The use of automated build tools.

Answer

Regular team retrospectives.

Question 12

If you have a 'bottleneck', how does increasing local efficiency at a non-bottleneck step affect the system?

Accepted Answer

It increases the pile-up at the bottleneck.. Increasing speed at a non-bottleneck simply pushes more work to the bottleneck, increasing the pile-up without increasing system throughput.

Answer

It reduces the cycle time of the entire system.

Answer

It has no effect on the system.

Answer

It improves the total throughput of the system.

Question 13

What is the primary benefit of 'Standardized Work' in a Lean environment?

Accepted Answer

It creates a baseline for improvement.. Standardized work provides a consistent baseline, which is necessary for measuring the impact of improvements (Kaizen).

Answer

It reduces the need for skilled workers.

Answer

It eliminates the need for team collaboration.

Answer

It makes the work boring and repetitive.

Question 14

Which of the following best describes the 'Respect for People' principle?

Accepted Answer

Empowering individuals to improve their own work processes.. Respect for people involves empowering them, providing them with the tools they need, and involving them in the improvement process.

Answer

Removing all performance management.

Answer

Allowing everyone to work from home.

Answer

Paying the highest salaries in the industry.

Question 15

You are working in an environment where documentation is mandatory for compliance. Using the DA toolkit, how should you approach this?

Accepted Answer

Consult the 'Produce Potentially Consumable Solution' goal and evaluate documentation options that fit your compliance needs.. The 'Produce Potentially Consumable Solution' goal provides options for documentation levels, allowing you to satisfy compliance while keeping the process as lean as possible.

Answer

Avoid all documentation.

Answer

Use the same documentation as the Waterfall team.

Answer

Create a new documentation process from scratch.

Question 16

Which DA process goal is specifically concerned with the early stages of a project to ensure the team is aligned?

Accepted Answer

Inception.. The 'Inception' phase (or 'Initiate' goal) is where the team sets the foundation, aligns on scope, and agrees on the initial WoW.

Answer

Ensure Continuity.

Answer

Produce Potentially Consumable Solution.

Answer

Improve Team Velocity.

Question 17

Which DA concept describes the idea that teams should be able to choose their own way of working?

Accepted Answer

Choose Your WoW.. The 'Choose Your WoW' mindset is a foundational pillar of DA, empowering teams to self-organize and adapt.

Answer

Standardized Agile.

Answer

Command and Control.

Answer

Managed Delivery.

Question 18

Which THREE of the following are examples of organizational-level process goals in Disciplined Agile?

Accepted Answer

Improve Team Velocity.. DA includes goals for the enterprise, not just the team level, such as 'Coordinate Activities', 'Improve Team Velocity', and 'Grow Team Members'.

Answer

Daily Stand-up Frequency.

Answer

Select the Project Lifecycle.

Question 19

Question 20

What is the primary benefit of the 'Guided Continuous Improvement' (GCI) approach in Disciplined Agile?

Answer

It forces every team to use the exact same metrics.

Answer

It eliminates the need for retrospectives.

Answer

It mandates the use of only one specific lifecycle.
