In the context of a project involving new technology and an approach unfamiliar to the team, it is crucial for the project manager to facilitate the identification of a Minimum Viable Product (MVP). This strategy allows the team to focus on creating a product with enough features to satisfy early adopters and provide feedback for future product development. The MVP concept is a core component of agile methodologies, which are part of the PMI's approach to project management as outlined in the PMBOKGuide and the Agile Practice Guide.
By validating assumptions early on, the project manager can help the team build confidence in their work and address the customer's concerns regarding market reception by demonstrating a tangible iteration of the product.

According to the PMBOKGuide Seventh Edition, one of the project management principles is to engage stakeholders actively and frequently. This means that the project manager should identify and analyze the needs, expectations, and interests of all stakeholders, and involve them appropriately throughout the project life cycle. The stakeholder register is a document that lists the key stakeholders, their roles, responsibilities, and level of influence on the project. The stakeholder engagement plan is a document that describes the strategies and actions to communicate with, manage, and influence the stakeholders.
In this scenario, the project manager has discovered that the local community was not included in the stakeholder register, which has caused them to oppose the project. This is a serious issue that can affect the project's performance, reputation, and acceptance. Therefore, the project manager should not disregard these stakeholders, as this would violate the principle of stakeholder engagement and potentially escalate the conflict. The project manager should also not just explain to the community members why they were not included as stakeholders, as this would not address their concerns or expectations. The best option is to update the stakeholder register and revise the stakeholder engagement plan, as this would allow the project manager to acknowledge the community as a stakeholder, assess their impact and interest, and develop appropriate strategies and actions to engage them effectively and proactively.
