In a hybrid project delivery approach, the business case is the artifact that ensures project benefits have been identified. It provides the rationale for the project by outlining the expected business benefits and aligning them with the organization's strategic goals. The business case is developed during the project initiation phase and is used to justify the investment in the project. It includes an analysis of the costs, benefits, risks, and opportunities associated with the project.
PMBOK Guide and PMP certification materials which discuss the importance of the business case in project management, particularly in hybrid and other project delivery approaches. The business case is a critical document that supports decision-making processes and ensures that the project aligns with the organization's strategic objectives and delivers the intended benefits.

Organizing more frequent sprint reviews with a broader audience is a key practice in Agile methodologies to ensure that the increments meet the end users' quality requirements. This approach allows for continuous feedback and collaboration, which are essential for Agile teams. It enables the team to present the increment to stakeholders, including end users, and receive immediate feedback that can be incorporated into the next sprint. This aligns with Agile principles of customer collaboration and responding to change123.

When a consultant requests changes to a software component during an iteration, claiming it does not meet market requirements, the project manager should continue the iteration and review the change with the customer. This action ensures that the iteration's progress is not halted while also addressing the consultant's concerns. It is essential to involve the customer in the decision-making process since they have a vested interest in the product's success and alignment with market needs. This approach is consistent with the principles of stakeholder engagement and communication found in both PMP and business analysis best practices.

The PMBOK Guide, which outlines the project management framework, emphasizes the importance of stakeholder engagement and communication throughout the project life cycle1.
The PMI Professional in Business Analysis (PMI-PBA) guide highlights the role of business analysts in facilitating communication between stakeholders and ensuring that project outcomes align with business needs23.
Discussions among PMP professionals suggest that addressing changes without disrupting the current iteration's workflow is a common practice, and customer involvement is crucial

In the context of the PMP objectives, when faced with unforeseen circumstances that impact project acceptance criteria, the project manager should adapt the project management plan and activities to align with the new conditions while still meeting the project objectives. Transitioning on-site training to online sessions is a proactive approach that ensures the training objectives are still met despite the shift to remote work. This aligns with the PMI's emphasis on flexibility and adaptability in project execution.
