DAF Practice Test 16 — 15 Questions

Question 1

Your organization wants to transition to a 'Pull' system. What is the most important prerequisite?

Accepted Answer

Establishing and enforcing WIP limits.. A Pull system in lean/agile means work is pulled into the system only when there is capacity to handle it, rather than being pushed in based on forecasts or schedules. The most important prerequisite for a Pull system is establishing and enforcing Work-In-Progress (WIP) limits, because without them there is no mechanism to signal when new work can be pulled. WIP limits create the 'pull' signal by constraining how much work can be in progress at once, forcing the team to finish before starting new items.

Answer

Eliminating all meetings.

Answer

Moving to a cloud-based development environment.

Answer

Hiring more experienced team members.

Question 2

If you observe a high rate of 'blocked' items on your Kanban board, what is the most appropriate action?

Accepted Answer

Swarm on the blocked item to clear the impediment immediately.. A high rate of blocked items signals that work is getting stuck and flow is being disrupted, so the most appropriate action is to swarm on the blocked item to clear the impediment immediately. Swarming means the team temporarily focuses multiple people on the blocked work to unblock it, which restores flow and prevents the blockage from cascading into further delays. This is a core Kanban and Disciplined Agile practice for managing flow.

Answer

Remove the blocked items from the board.

Answer

Wait until the next daily stand-up to discuss the blocks.

Answer

Start new work to keep the developers busy.

Question 3

What is the purpose of the 'DA Toolkit'?

Accepted Answer

To provide a structured way for teams to tailor their processes.. The DA Toolkit provides a structured way for teams to tailor their processes by offering a collection of practices, process goals, and decision points. It is designed to help teams choose their way of working (WoW) based on their context, rather than prescribing a rigid set of rules. This makes it a flexible guide for process tailoring.

Answer

To replace all other agile frameworks.

Answer

To provide a set of strict rules for Scrum teams.

Answer

To act as a project management tool like Jira.

Question 4

Which TWO of the following are primary benefits of limiting Work-in-Progress (WIP)?

Accepted Answer

Reduction in total cycle time.. Option B is correct because limiting WIP reduces the amount of work queued at each stage, which shortens the time any single item spends waiting and being worked on, thereby reducing total cycle time (Little's Law: Cycle Time = WIP / Throughput). Option D is correct because capping WIP prevents work from piling up and hiding problems; when a stage hits its WIP limit, the blockage becomes visible and exposes the underlying process bottleneck that must be addressed. Option A is incorrect because limiting WIP does not eliminate all meetings; it may change their frequency or format but meetings are not inherently removed. Option C is incorrect because limiting WIP primarily reduces cycle time and variability rather than directly increasing total throughput, which depends on the bottleneck's capacity. Option E is incorrect because WIP limits are a system-level flow control mechanism, not a technique for improving individual employee performance.

Answer

Elimination of all meetings.

Answer

Increased total throughput of the system.

Answer

Improved individual employee performance.

Question 5

When applying the DA toolkit, you discover that your team's 'Explore Scope' process goal has multiple high-performing options. How do you decide which one to implement?

Accepted Answer

Analyze your team's context factors and select the option that best addresses your current challenges.. DA's process goals are deliberately populated with multiple viable options, and the toolkit does not prescribe which to use. The correct approach is to evaluate the team's specific context factors — such as team size, distribution, regulatory constraints, customer availability, and technical complexity — and select the option whose trade-offs best address the team's current challenges. This is the essence of 'choose your WoW': decisions are context-driven, not popularity-driven or effort-minimizing.

Answer

Select the option with the fewest steps.

Answer

Randomly select an option to experiment.

Answer

Select the option that is most popular in the industry.

Question 6

Which THREE of the following are considered 'Lean' practices in DA?

Accepted Answer

Eliminating waste. In Lean Data Analytics (DA), eliminating waste (A) is a core principle because it removes non-value-adding activities such as redundant data processing, rework, or waiting, directly improving efficiency. Reducing WIP (D) is correct because limiting work-in-progress prevents bottlenecks, shortens cycle times, and aligns with Lean's pull-based, just-in-time approach. Optimizing flow (E) is also correct because Lean emphasizes smooth, continuous delivery of value through value-stream mapping and removing impediments, ensuring data products move steadily from ingestion to insight. In contrast, increasing batch sizes (B) contradicts Lean by creating larger queues and delaying feedback, while adding unnecessary roles (C) introduces waste in the form of over-processing and organizational bloat, neither of which is a Lean practice.

Answer

Increasing batch sizes

Answer

Adding unnecessary roles

Question 7

What is the primary benefit of the 'Iterative' approach over a 'Big Bang' delivery approach?

Accepted Answer

It allows for early detection and correction of errors. The iterative approach focuses on risk reduction and feedback through smaller, frequent releases.

Answer

It eliminates the need for project managers

Answer

It requires less documentation than waterfall

Answer

It ensures that all team members are always busy

Answer

It guarantees that no changes will be made to requirements

Question 8

What is the primary objective of 'Iterative' development in a project?

Accepted Answer

To deliver working, tested functionality frequently. The primary objective is to deliver value in small, manageable increments.

Answer

To avoid all documentation

Answer

To ensure the project manager has total control

Answer

To allow the team to work on different projects simultaneously

Question 9

Your team needs to balance the 'Adaptive' vs 'Predictive' lifecycle. Which criteria should you prioritize when making this choice?

Accepted Answer

The level of uncertainty and risk in the project. The choice between Adaptive (Agile) and Predictive (Waterfall) lifecycles hinges primarily on how well requirements and risks are understood upfront. High uncertainty and risk favor an Adaptive approach because iterative delivery allows course correction as new information emerges. Conversely, low uncertainty and well-understood requirements favor a Predictive approach where detailed upfront planning is safe. Budget and team tenure are secondary considerations that do not fundamentally dictate lifecycle selection.

Answer

The tenure of the team members

Answer

The total budget allocated to the project

Answer

The seniority of the stakeholders

Question 10

Which of these is the best definition of 'Value' in Lean?

Accepted Answer

Anything the customer is willing to pay for.. In Lean, value is defined from the customer's perspective: any activity or output for which the customer is willing to pay. This definition drives the identification of value-adding versus non-value-adding (waste) activities. Options A, C, and D are internal metrics that do not reflect customer willingness to pay.

Answer

The number of tasks completed in a sprint.

Answer

The total effort hours spent by the team.

Answer

The number of lines of code written.

Question 11

Which of the following best describes the 'Enterprise Awareness' principle in Disciplined Agile?

Accepted Answer

Teams should work to improve the enterprise, not just their local team.. Enterprise Awareness in DA means teams consider the whole organisation and work to improve the enterprise, not just their local team. Option C captures this directly: teams should optimise for enterprise value rather than local metrics. This principle counteracts siloed behaviour and local optimisation.

Answer

Teams should ignore company policies if they impede agility.

Answer

The team should delegate all integration tasks to a central architecture group.

Answer

Teams should only focus on their own code quality to ensure speed.

Question 12

Your team is experiencing high WIP levels during the development phase. Which Lean technique should you apply first to identify the primary cause of this congestion?

Accepted Answer

Conduct a Value Stream Mapping session to visualize handoffs and queues.. Value Stream Mapping (VSM) is the Lean technique for visualizing the end-to-end flow of work, including handoffs, queues, and wait times, which reveals where WIP accumulates and why. Before applying countermeasures like WIP limits or swarming, the team must see the current state to identify the primary constraint. VSM provides that diagnostic view.

Answer

Require developers to work overtime to clear the backlog.

Answer

Increase the team size to handle the overflow.

Answer

Implement a mandatory daily stand-up meeting extension.

Question 13

Which THREE of these activities are part of the 'Inception' phase in DA?

Accepted Answer

Identifying initial stakeholders. In the Disciplined Agile (DA) lifecycle, the Inception phase is the startup stage where the team is stood up and the initiative is framed before construction begins. Option B (Identifying initial stakeholders) is correct because Inception includes recognizing who has an interest in or will be affected by the solution so their needs can shape the vision. Option C (Aligning on the project vision) is correct because a primary Inception goal is to reach a shared understanding of the problem, the desired outcome, and the high-level solution direction. Option D (Forming the team) is correct because Inception covers organizing and chartering the team, including roles, initial staffing, and working agreements, so the team is ready to move into construction. Option A (Developing the complete product) belongs to the Construction/transition work, not Inception, and Option E (Closing out the final project budget) is a Transition/closeout activity, so neither is part of Inception.

Answer

Developing the complete product

Answer

Closing out the final project budget

Question 14

You notice that the team's 'Cycle Time' is increasing despite no change in the amount of work. What should you investigate?

Accepted Answer

The presence of hidden queues between workflow states.. Cycle time increases when work spends more time waiting between workflow states, and hidden queues — unacknowledged wait states such as 'waiting for review', 'waiting for test environment', or 'waiting for approval' — are the most common cause. Investigating these queues reveals where work is piling up and why flow has slowed even though the volume of work has not changed.

Answer

The team's office lighting.

Answer

The number of coffee breaks taken.

Answer

The team's motivation level.

Question 15

A team is using the 'Continuous Delivery: Agile' lifecycle. They find that they are struggling to meet their commitments. Based on DA, what should they evaluate?

Accepted Answer

Review their process goals within the DA toolkit to identify potential improvements.. In DA, when a team struggles to meet commitments, the prescribed response is to examine the relevant process goals in the toolkit and identify which decision points and practices need adjustment — for example, planning, estimation, or coordination practices. This is guided continuous improvement applied to a delivery problem: diagnose against the toolkit, then choose better-fitting options. Switching lifecycles or adding ceremonies without diagnosis would violate DA's context-driven approach.

Answer

Switch to a Waterfall lifecycle immediately.

Answer

Increase the frequency of daily stand-ups.

Answer

Assign a dedicated Scrum Master to force compliance.
