Upon being assigned to a project, especially one as critical as providing water access to a community, the project manager's next step should be to start project planning and develop the project management plan. This is in accordance with the PMBOK Guide's recommended process, which emphasizes the importance of planning in the project management life cycle. The planning phase involves defining the project scope, objectives, and procedures, which are crucial for the successful delivery of the project outcomes. It ensures that all aspects of the project are methodically approached and that the project's goals are aligned with the community's needs.

The Project Management Professional (PMP) emphasizes the importance of leadership styles in project management. It suggests that a project manager should be able to move from one leadership style to another depending on the situation, which is crucial to be extraordinarily effective1. Moreover, the Professional in Business Analysis (PMI-PBA) highlights the role of a project manager in engaging and motivating the team towards a shared vision to achieve together2. Therefore, studying and determining the appropriate leadership style is essential for improving team performance and commitment.

The best course of action for a project manager who is experienced in both predictive and adaptive approaches, when dealing with stakeholders familiar mostly with predictive projects, is to first understand the scope complexity and project magnitude. This initial step is crucial as it helps in determining the most suitable approach for the project at hand. A hybrid approach may be beneficial in some cases, but without a clear understanding of the project's demands and challenges, it's premature to decide on the methodology. The project manager should assess the project's needs, evaluate the stakeholders' familiarity with different methodologies, and consider the potential need for training if an adaptive approach is chosen. This approach aligns with the PMI's guidance on tailoring the project management approach to the unique aspects of the project and the environment in which it operates.

When developing a coaching model to support and recognize team members' growth, it is essential for the project manager to consider the individual and personal objectives of the team members. This personalized approach ensures that the coaching strategy is aligned with the unique needs and goals of each team member, fostering an environment of growth and development. Tailoring the coaching to individual objectives also helps in maximizing the effectiveness of the coaching process23.

Given the nature of the project, where the hardware part has detailed specifications already defined and the user interface software has only a basic specification with a requirement for a user experience design approach, a hybrid approach would be most suitable. This approach allows for flexibility and adaptability in the software development process (using agile methodologies), while maintaining a structured and predictable approach for the hardware deliveries (using a predictive approach). This ensures that both aspects of the project can progress efficiently and effectively, catering to their unique requirements.
