The design team is working on a high-fidelity prototype to create a moreenjoyable user experience.

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.References:https://trailhead.salesforce.com/en/content/learn/modules/salesforce-strategy-designer-certification- prep/engage-technical-stakeholders
