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.
