The correct answer is D – Estimating the relative size of stories by using story points.

Planning poker is a consensus-based estimation technique used in Agile to assign relative size (often using story points) to product backlog items. Each team member selects a card to indicate their estimate, and the group discusses discrepancies to reach agreement.

From the PMI Agile Practice Guide:

“Planning poker is a consensus-based estimation technique that helps teams estimate the size of user stories using story points. It supports collaboration and shared understanding.”

(PMI Agile Practice Guide, Section 5.3 – Estimation Techniques)

Mike Griffiths writes:

“Planning poker helps teams perform relative sizing using a modified Fibonacci sequence. The goal is not precision, but shared understanding and relative complexity comparison.”

(Mike Griffiths, PMI-ACP Exam Prep Book, Chapter 5 – Adaptive Planning)

Why other options are incorrect:

A describes analogy-based estimation, not planning poker.

B refers to “bucket system” estimation, a separate technique.

C refers to dot voting, which is a prioritization—not estimation—tool.

Answer: D

══════════════════════════════════════════════════

The correct answer is B – Suggest the Product Owner prioritize the work items by feature to maximize value.

In Agile, the Product Owner is responsible for backlog prioritization. When multiple stakeholders have differing priorities, it is the Product Owner’s job to evaluate business value and ROI to determine which features deliver the most value and should be addressed first.

From the PMI Agile Practice Guide:

“The Product Owner works closely with stakeholders to ensure that the most valuable work is prioritized in the backlog. When multiple stakeholders have competing interests, the Product Owner helps mediate and prioritize based on value delivery.”

(PMI Agile Practice Guide, Section 3.4 – Value-Based Prioritization)

Mike Griffiths adds:

“Agile avoids trying to define all requirements up front. Instead, the backlog is groomed regularly, and the Product Owner ensures that the team is working on the highest value features.”

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

Other options are less effective:

A contradicts Agile principles by suggesting complete upfront requirement definition.

C puts responsibility on the customer instead of the empowered Product Owner.

D implies a waterfall approach by requiring clarity before starting.

Answer: B

Agile teams evaluate new tools or technologies throughspikes—time-boxed research or experimentation tasks. According to thePMI Agile Practice Guide (Section 5.2: Spikes and Exploration)andMike Griffiths’ PMI-ACP Exam Prep Book (Chapter 6: Adaptive Planning), the appropriate way to introduce new technology is toengage the teamin the decision and create abacklog itemfor a spike to evaluate its viability.

Option Cis correct: it follows agile collaboration and backlog grooming practices.

Option Askips team consensus and formal prioritization.

Option Bcontradicts self-organizing team principles.

Option Dmay delay necessary action and is better suited for process discussions, not technical trials.

The correct answer is A – Inform the stakeholder that all updates are provided in the sprint review sessions and encourage them to attend.

The Sprint Review is designed to provide transparency to stakeholders, demonstrate completed work, and gather feedback. Stakeholders should be encouraged to attend these events to stay updated and engaged.

From the PMI Agile Practice Guide:

“Sprint reviews are intended to engage stakeholders in reviewing completed work and discussing priorities. This event ensures transparency and encourages stakeholder collaboration.”

(PMI Agile Practice Guide, Section 5.5 – Stakeholder Engagement)

Mike Griffiths adds:

“Agile teams encourage stakeholder participation in regularly scheduled review meetings to maintain alignment and foster transparency.”

(Mike Griffiths, PMI-ACP Exam Prep Book, Chapter 3 – Stakeholder Engagement)

Other options:

B adds non-Agile overhead and undermines Agile transparency mechanisms.

C and D are dismissive and uncollaborative, potentially damaging relationships.

Answer: A

══════════════════════════════════════════════════

The correct answer is D – Communicate the risk of a negative ROI to the stakeholders, and update the release plan. Agile values transparency and collaboration. When the team identifies risks to business outcomes such as ROI, they must promptly inform stakeholders and work collaboratively to reassess scope, value, and strategy.

From the PMI Agile Practice Guide:

“Agile teams provide ongoing visibility to stakeholders. If delivery metrics reveal financial concerns, the product owner and stakeholders evaluate whether to pivot, persevere, or stop.”

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

Mike Griffiths adds:

“Agile planning is value-based. If ROI is unlikely to be achieved, stakeholders must be informed early so informed decisions can be made.”

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

Incorrect options:

A assumes trimming scope is sufficient without stakeholder input.

B contradicts team stability and morale principles.

C helps identify inefficiencies but doesn’t replace transparency.

Answer: D

Once scope and acceptance criteria are known, the next step is toestimate the size and effort of backlog items, which enables planning. ThePMI Agile Practice Guide (Section 5.2: Backlog Estimation)andMike Griffiths’ PMI-ACP Exam Prep Book (Chapter 6: Adaptive Planning)recommend using estimation techniques (e.g., story points, T-shirt sizing) to determine therelative effort of each backlog itembefore performing release or sprint planning.

Option Dis correct: backlog estimation enables velocity-based forecasting.

Option AandBcome after estimation is complete.

Option Cis too narrow—iteration planning comes later.

Theretrospectiveis the agile ceremony designed for teams toinspect and adapttheir process based on actual performance. According to thePMI Agile Practice Guide (Section 5.6: Retrospectives), discussingvelocity issues and delivery concernsduring retrospectives allows the team to collaboratively identify improvement actions.

Mike Griffiths in thePMI-ACP Exam Prep Book (Chapter 6: Adaptive Planning)also notes thatretrospectives are the best settingto discuss variations in velocity and refine estimation or planning practices based on empirical evidence.

Option Cis correct: the retrospective is where the team adapts based on reality.

Option Amay come later but doesn’t address the root issue.

Option Bgoes against agile principles of stable teams and empirical planning.

Option Dis reactive and may mask underlying process issues.

Security features are typically considerednon-functional requirements (NFRs), which should be captured in theproduct backlogand prioritized accordingly. As per thePMI Agile Practice Guide (Section 5.1: Product Backlog)andMike Griffiths’ PMI-ACP Exam Prep Book (Chapter 6: Value-Driven Delivery), any requested functionality—whether business- or system-level—must beclearly defined as a backlog itemso the team can plan for it.

Option Ais correct: security requirements should beadded to the backlog and prioritizedlike other features.

Option Bmay come later if implementation is unclear, but first, the work must be defined and logged.

Option CandDrepresent clarification steps but don’t directlysupport implementationas backlog management does.

A complete and realistic backlog must include not onlyfunctional storiesbut alsonon-functional and support taskssuch as infrastructure setup, analysis, and design. ThePMI Agile Practice Guide (Section 5.2: Backlog Composition)andMike Griffiths’ PMI-ACP Exam Prep Book (Chapter 6: Adaptive Planning)emphasize including all types of work in the backlog to ensureaccurate effort planning.

Option Dis correct: effort must includetechnical tasks, not just feature delivery.

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

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

The project manager should engage in a constructive conversation with the team member to understand the reasons behind the performance dip. Instead of focusing on blame, it’s important to discuss the specifics of the project deliverables and identify any challenges or factors that may be affecting the team member's performance. Providing constructive feedback helps the team member understand the areas of improvement while maintaining a supportive environment. This approach encourages open communication, identifies potential solutions, and can lead to a positive outcome for both the team member and the project.
