What do you do if you need to delegate mobile app design to UX/UI experts?

Certainly! I can take point on the entire user experience (UX) and user interface (UI) design for your mobile app. This includes understanding user needs through research, crafting the information architecture, designing the user flows, and creating a visually appealing and functional interface.

I wouldn't agree with it. It can be also useful that the User experience experts interpret the need for a mobile app to address the user and customer needs and identify why an app or requirements for the app are useful. Provide data and possible interpretation to help the UX expert understand how you came to the conclusion.

Additional it helps if the ux experts also have domain knowledge of your business or requirements. What works well in some area doesn't mean it works in another as well. This helps reducing the iterations of the designs as more knowledge is already available.

This is where user Journey Maps are a very useful tool. They are the bridge between understanding the problems end users have with the current UI today, what improvements are needed in the new UI, and thus, the requirements for the UX/UI team in building the new interface. It not only helps capture the UI requirements, but educates end users as to the art of the possible. A good journey map, together with a mock up tool makes for an excellent combination.

Define Requirements: Clearly outline project goals and user needs. Research and Select: Find experienced UX/UI designers or agencies. Communicate Expectations: Share your vision and preferences. Collaborative Ideation: Brainstorm concepts and user flows together. Wireframing and Prototyping: Visualize layout and interactions with wireframes and prototypes. Visual Design: Define visual elements aligned with brand identity and user preferences. Iterative Process: Review, provide feedback, and iterate designs. User Testing: Gather feedback from real users to refine the design. Finalization: Prepare final designs and documentation for development. Ongoing Collaboration:Maintain communication throughout development for successful implementation.

Communicate the companies vision as well as the product and app vision. Based on this there might be also frameworks available for the UX designers, like Design Libraries, Corporate identity.

Keep in mind that even after a successful user test before implementation the feedback after users start using the app can vary and there should be some iterations considered to improve the design.
