For an interface, understand the user, their task, the interface's previous and next steps, and the content and functionality needed to support the user.
Why to use? 4-corners helps teams understand how an interface fits into a user's journey through a system, so they can optimize the content and functionality and improve the user's experience.
When to use? Use 4-corners any time you need to sketch or review and interface.
