Working with a great designer or design team can be an invaluable asset to any team. With clear communication channels, and free-flowing co-operation, the designer should give you everything you need to speed up the building process and limit questions and confusion as much as possible. What can you, the UX developer, do to ensure that the product you have built is delivered in a timely manner without sacrificing the quality of the user interface and user experience?
Get your designers involved from day one, and keep them involved throughout the entire UI/UX development process. Make sure to establish clear communication lines and consistent messaging between developers and the designers.
