The product owner should ensure that the stakeholder has easy access to relevant project data by utilizing the information radiator. An information radiator is a visual display of important project information, such as progress, financials, and key metrics. By giving the stakeholder access to this information, they can get the data they need without disrupting the team's workflow or waiting for specific requests. The scrum master can help facilitate this process by making sure the relevant data is readily available and visible.

The correct answer is D - Ensure that planning and prioritizing includes consideration of security requirements.
Non-functional requirements (such as security, performance, or compliance) must be included in backlog prioritization and planning sessions. Agile teams must incorporate these concerns into their definition of done and acceptance criteria to ensure continuous compliance and product integrity.
PMI Agile Practice Guide emphasizes:
"Non-functional requirements (NFRs) must be prioritized and planned for alongside functional user stories.
They are not optional, and failure to include them early often leads to system failure or technical debt." (PMI Agile Practice Guide, Section 5.3 - Planning Considerations) Mike Griffiths writes:
"Agile teams should treat NFRs as constraints that are baked into every sprint. Rather than isolating them, they should be considered in backlog refinement and story definition." (PMI-ACP Exam Prep, Chapter 5 - Adaptive Planning) Other options:
* A may help, but meeting agendas alone are not sufficient for managing NFRs.
* B may assist with knowledge, but it doesn't guarantee prioritization.
* C implies treating the NFR as a risk rather than a core requirement.

The information radiator is a key tool in Agile that provides a real-time, visual display of the project's current status, including progress, completed tasks, blockers, and upcoming work. This is typically made accessible to all stakeholders and is updated regularly to ensure transparency and communication. Instead of relying on emails or meeting invites, the Scrum Master should direct the customer representative to the information radiator, as it provides the most up-to-date and easily accessible information about the project's progress. This encourages transparency and aligns with Agile principles of open communication and visibility.

A key agile principle is that user stories should include clear acceptance criteria, which must be reviewed and accepted by the product owner. According to the PMI Agile Practice Guide (Section 5.2: User Stories and Acceptance Criteria) and Mike Griffiths' PMI-ACP Exam Prep Book (Chapter 6: Value-Driven Delivery), acceptance criteria ensure that the team and product owner share a clear understanding of what constitutes
"done."
* Option A is correct: having the product owner validate acceptance criteria ensures alignment.
* Option B addresses technical quality but not stakeholder dissatisfaction.
* Option C unfairly shifts blame without addressing communication.
* Option D goes against agile's iterative and flexible nature.

In Agile, building increments and ensuring early feedback are key to delivering value quickly and meeting tight deadlines. By focusing on delivering a minimum viable product (MVP), the team can provide the customer with a version of the product that delivers essential functionality early, which allows for feedback and adjustments before the final version is released. This approach helps the team stay within the limited budget and timeline while ensuring that they are delivering the most important features first. Additionally, early customer feedback ensures that the team is on track to meet the project goals and allows for the rapid adaptation of the product.
