This option is most aligned with the principles of project management as outlined in the PMBOKGuide, which emphasizes the importance of collaborative planning and goal setting. Engaging the team in defining the overall objective ensures that all members are on the same page and committed to the project's success.
This approach leverages the expertise of the team members and fosters a sense of ownership and accountability.

When developing a product, it is crucial for a project manager to consider the stakeholder's needs. This aligns with the principle that stakeholders' needs and expectations are to be met in order to manage a project successfully. The PMBOKGuide emphasizes the importance of identifying stakeholders and understanding their needs and expectations as a part of the project management process. Stakeholders are individuals or groups who are actively involved in the project or whose interests may be affected by the execution or completion of the project. They can influence the project and its results. The concerns of the international stakeholder about the product not meeting the client's needs highlight the necessity of integrating their needs into the planning and development process12.

According to the PMBOK Guide, consensus decision-making is a technique that ensures that all input and ideas from a group or team are considered until a final decision that is acceptable to all emerges. This approach relies heavily on respectful dialogue and open-mindedness, and it is often used to build consensus regarding the requirements in project management. By organizing a face-to-face meeting with all stakeholders, the project manager can facilitate the communication and collaboration among them, and elicit their needs, expectations, and preferences. This can help to resolve any conflicts or contradictions, and reach a common understanding of the project requirements. References:
