A complete and realistic backlog must include not only functional stories but also non-functional and support tasks such as infrastructure setup, analysis, and design. The PMI Agile Practice Guide (Section 5.2: Backlog Composition) and Mike Griffiths’ PMI-ACP Exam Prep Book (Chapter 6: Adaptive Planning) emphasize including all types of work in the backlog to ensure accurate effort planning.

Option D is correct: effort must include technical tasks, not just feature delivery.

Option A suggests speculation on velocity and cost increases, which is unreliable.

Option B and C (adding buffers or padding estimates) violate agile’s principle of transparency and simplicity.

According to the PMI Agile Practice Guide (Section 7.2.1), the Scrum Master’s role includes removing impediments and shielding the team from outside interference. A team member being pulled into work on a different project is a classic example of an impediment. Recording the issue in a risk register is appropriate, but more importantly, the Scrum Master must communicate and resolve the issue.

Mike Griffiths in his PMI-ACP Exam Prep Book (Chapter 3: Team Performance) emphasizes that agile teams require full dedication and protection from context switching, as multitasking reduces productivity and increases error rates. Merely documenting the issue is not enough—the Scrum Master must take steps to escalate and resolve the interference, potentially by negotiating with the former supervisor or re-clarifying role boundaries.

Therefore, Option C is correct as it involves actively addressing the threat rather than passively monitoring or adjusting around it.

The correct answer is D – Meet with project stakeholders to review the backlog and determine if the scope should be adjusted. Agile emphasizes continuous stakeholder collaboration and delivering maximum value. If the remaining backlog may not contribute significant value, it’s prudent for the Product Owner to reassess scope and validate changes with stakeholders.

From the PMI Agile Practice Guide:

“Engage stakeholders continuously to review priorities and business value. If the product delivers sufficient value earlier than anticipated, the scope may be reduced or the project closed.”

(PMI Agile Practice Guide, Section 3.4 – Value-Driven Delivery)

Mike Griffiths adds:

“Early delivery of value allows teams to stop work that no longer serves business objectives. This requires transparent communication with stakeholders to validate scope adjustments.”

(Mike Griffiths, PMI-ACP Exam Prep, Chapter 3 – Value-Driven Delivery)

Incorrect options:

A assumes authority without consulting stakeholders.

B doesn’t address the possible need for scope reduction.

C skips stakeholder validation before deployment decisions.

Answer: D

In the scenario described, the team is discussing the root causes of the technical problems that led to delayed deliverables, which indicates they are being proactive. One of the agile principles is to deliver working software frequently and adapt to change, and this situation shows the team is reflecting on their issues to improve future performance by identifying ways to balance the demands placed on the team (workload, deadlines, etc.) with their available capacity and necessary competencies.

A cumulative flow diagram (CFD) is a powerful tool to visualize the flow of work across different stages of the process and identify where bottlenecks are occurring. By using a CFD, the team can see the buildup of work in specific columns, such as the " Ready to be tested " queue, and determine where delays are happening. Identifying bottlenecks is the first step in improving flow and addressing the slower delivery. Once the bottleneck is identified, the team can make adjustments to improve speed, such as optimizing the testing process or redistributing workload.

The correct answer is D — Engaged key stakeholders periodically to collect requirements.

Agile is based on frequent stakeholder collaboration. Continuous engagement ensures evolving needs are captured and prevents misalignment. Waiting for planning meetings or demos is too late to catch missing input.

PMI Agile Practice Guide:

“Agile teams ensure stakeholder engagement is ongoing throughout the project. This helps validate requirements and prevent surprises during reviews.”

(PMI Agile Practice Guide, Section 4.2 – Stakeholder Engagement)

Mike Griffiths:

“Stakeholders should be consulted early and often. Relying on static requirements leads to gaps. Agile teams maintain constant feedback loops.”

(PMI-ACP Exam Prep, Chapter 3 – Value-Driven Delivery)

Incorrect options:

A is too early and one-time.

B may help but is reactive.

C is a predictive approach inconsistent with agile.

Answer: D

Predictable flow in agile is achieved by reducing variability in story size and complexity. According to the PMI Agile Practice Guide (Section 5.7: Flow-based Agile and Kanban), working with small, similarly sized user stories increases throughput predictability and improves cycle time.

Mike Griffiths in the PMI-ACP Exam Prep Book (Chapter 6: Value-Driven Delivery) supports breaking large stories into smaller, testable chunks as a way to stabilize delivery and forecasting.

Option A is correct: small user stories reduce variability and support predictable flow.

Option B supports testability but doesn’t directly improve flow.

Option C and D are too broad or conceptual to specifically improve predictability.

In Agile, the Definition of Done (DoD) typically requires that the feature be both developed and fully integrated into the release package before it is considered complete. Even though the feature was successfully tested and demonstrated by QA, if it is not included in the release package, it is not technically completed according to the DoD. Therefore, its story points should not be added to the burndown chart until it is actually part of the release. This ensures that the team’s progress is accurately tracked based on completed, released work.

To calculate cycle time, we use Little’s Law, which states:

Where:

WIP (Work in Progress) = 50 tickets

Throughput = 200 tickets per 8-hour shift

Now, applying the formula:

The correct answer is B – Facilitate an open and focused team discussion that reinforces team agreements. Agile teams are built on collaboration, mutual respect, and self-organization. When conflict arises about role expectations or task assignments, the Scrum Master should create a safe space for open discussion to reinforce working agreements and promote shared accountability.

From the PMI Agile Practice Guide:

“Agile leaders support team collaboration by encouraging open conversations. When team dynamics are strained, the Scrum Master facilitates discussions to reinforce team norms, self-organization, and equality of contribution.”

(PMI Agile Practice Guide, Section 4.3 – Team Performance and Working Agreements)

Mike Griffiths further states:

“Agile teams succeed when responsibilities are shared and roles are not rigidly defined. The Scrum Master should facilitate a discussion that encourages shared ownership and mutual respect for all tasks.”

(Mike Griffiths, PMI-ACP Exam Prep, Chapter 4 – Team Performance)

Incorrect options:

A imposes action without addressing the root issue or respecting roles.

C brings external authority into a team matter, weakening self-organization.

D is partially correct but doesn’t resolve the immediate team conflict.

Answer: B
