A Servant Leader is one who focuses primarily on the growth and well-being of people and the communities to which they belong. The servant-leader shares power, puts the needs of others first and helps people develop and perform as highly as possible. In the context of this question, a Servant Leader would work to ensure that the team has all the resources and knowledge they need to define the steps and identify the risks of migrating data to a new system1.

When team engagement issues arise, especially in virtual environments, it is crucial to reflect with the team on whether agreed-upon practices (cadence, structure, tools) are still effective. This supports continuous improvement, a core Agile and PMI principle. Working with the team promotes psychological safety and empowers them to propose better formats for collaboration.
PMBOK Guide - Seventh Edition emphasizes team performance and tailoring practices to context. Agile environments also promote retrospective thinking to improve team dynamics.
Option B addresses accountability but doesn't resolve disengagement.
Option C is a good practice but doesn't tackle underlying disengagement.
Option D focuses on reporting structure, not team dynamics.

According to the PMBOK Guide, the project manager should consider the culture of the organization when choosing a leadership style for a project. The culture of the organization includes its values, norms, beliefs, and expectations that influence how people behave and interact. Different cultures may have different preferences and expectations for leadership styles, such as autocratic, democratic, participative, or laissez- faire. The project manager should adapt their leadership style to the culture of the organization to ensure effective communication, collaboration, and motivation of the project team and stakeholders.

In a hybrid approach, project managers need to adapt to different project life cycles and methodologies, including agile. Agile teams are self-organizing and empowered, and they value collaboration and feedback over command and control. Therefore, project managers are expected to become coaches or facilitators for agile teams, rather than traditional managers or leaders. They should support the team's autonomy, alignment, and accountability, and help them overcome impediments and deliver value. The capacity-building activities may not have adequately prepared the project managers for this role shift, which could cause issues in motivating the agile staff.

Once the project management plan is developed, approved, and communicated, the project transitions from planning to executing. The logical next step is to direct and manage project work-performing the work defined in the plan and producing deliverables via the work packages (D). Execution includes coordinating people and resources, managing stakeholder engagement, implementing planned quality activities, and producing work performance data for monitoring and control. Options A and B are planning activities that should already be complete or sufficiently mature before the plan is approved; defining deliverables and schedule details and estimating durations are part of developing baselines and subsidiary plans. Option C is incorrect because the scope baseline consists of the scope statement, WBS, and WBS dictionary; you do not
"incorporate the scope baseline into the scope statement" after the plan is approved. With an approved plan, the project manager should begin executing work packages while simultaneously monitoring performance against baselines to ensure delivery of the new service aligns with agreed scope, schedule, cost, and quality expectations.
