Explanation
The purpose of building and testing a Minimum Viable Product (MVP) is to validate or invalidate the essential features of the product, that is, the features that deliver the core value proposition and solve the user's problem. Testing an outline of all features and possibilities of the product or assessing essential features of the product with a large group of users are not suitable outcomes for an MVP, as they may introduce unnecessary complexity or bias.

Explanation
The team should use a prioritization matrix to justify the strategy. A prioritization matrix is a tool that helps evaluate and rank ideas or features based on two criteria, such as impact and effort. It helps determine the most valuable and viable solutions, and communicate the benefits and trade-offs of each option. References:

Explanation
A CX vision is a statement that describes the desired future state of the customer experience. It should be inspiring, aspirational, and feasible. To alleviate stakeholders' concerns about how it will impact the current product, a strategy designer should prototype an aspect of the vision that interacts with the current product and share insights with stakeholders. This can help them visualize and understand how the vision can be realized and what benefits it can bring. A brainstorming session may not be helpful if the stakeholders are already skeptical about the vision. Sharing objectives and key results may provide some context, but they do not show how the vision will affect the product.

Explanation
The best recommendation to help create alignment between the team is to share stories from customer research to create a common understanding of challenges, as this helps empathize with the customer pain points and needs and foster a user-centric mindset. Creating a prioritized product roadmap or defining acceptance criteria and testing may not address the root cause of the misalignment or the complexity of the user experience.

Explanation
The value proposition is the part of the business model canvas that represents desirability. It describes the value that the product or service offers to the customer segments, and how it solves their problems or satisfies their needs.
