Designing Speed with Progressive Enhancement

Web pages do not appear on the screen immediately and take time to load and render. This requires us to question the industry standard of Photoshop or JPEG comps as design deliverable because it only captures final state of the page and does not describe full page load cycle.

If we are to design effective user experience and not just a static pictures, how do we structure a new process and artifacts for effective UX conversation between product, design and development teams?

Sergey Chernyshev proposes a process similar to “storyboarding” in filmmaking as a new way to describe progressive rendering during design phases of the project. It breaks down the experience into multiple, well defined steps and frames conversations and design goals for product and design teams.

This process also describes how to give development teams a series of simple constraints aligned to each rendering step allowing them to create well structured pages using progressive enhancement.
