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.

Phases of feature development are needed from the strategy designer to inform a roadmap from MVP to mature offering. Phases of feature development are stages or steps that define how a feature or solution will evolve over time, from its initial version to its final version. They help plan and prioritize the scope and sequence of work, and communicate the vision and value proposition of the product or service. https://trailhead.salesforce.com/en/content/learn/modules/salesforce-strategy-designer-certification-prep/create-phases-of-feature-development

The key reason why the design team would engage the developer team is to validate technical limitations. Technical limitations are constraints or challenges that affect the feasibility or viability of a solution, such as platform capabilities, integrations, performance, security, or scalability. The design team should consult with the developer team to understand and address these limitations, and ensure that the solution is realistic and achievable. https://trailhead.salesforce.com/en/content/learn/modules/salesforce-strategy-designer-certification-prep/engage-technical-stakeholders

A challenge statement effectively articulates a complex UX problem by framing it in a way that highlights its significance, encourages involvement, and inspires action. It positions the issue as an opportunity for improvement, motivating the team to engage in finding solutions and driving positive change.

The technique that the designer should use to ensure the audience remains engaged is to ask open-ended questions to the audience to maintain their involvement. Open-ended questions are questions that require more than a yes or no answer, and invite the audience to share their thoughts, opinions, or feedback. Asking open-ended questions can help the designer capture the audience's attention, interest, and curiosity, as well as encourage interaction and dialogue. Turning the camera off may reduce the visual connection and rapport with the audience. Dedicating half of the meeting time to answering questions may not be enough to keep the audience engaged throughout the presentation.
