A good UX designer can easily explain the logic behind each decision in a design concept. This includes the information architecture, the hierarchy of page content, the flow and the assumptions made.
Sooner or later, animation will be introduced to the wireframe concept, and then making design decisions or explaining them becomes harder. Reasons such as “It will be cool!” or “It’s trendy” or ”exciting” are exactly the areas where a design starts to lose its strength. Animations deserve a far better ground in our design considerations. We should be justified in defining animations and explaining their purpose — just the same way that we explain all other elements in a design.
