Summary: Understanding and designing for Context of Use is vital to any successful UX project. Going beyond surface context will reveal depth insights that are required for UX Designers to get beyond "throw-away" UX Design. Context is critical for developing products built to last, built to be adopted long-term.
In this post, the topic of understanding Tasks and Context was discussed. Context of use is also called the 'problem space' as opposed to the solution space where tasks get translated into UI solutions. Context of use means understanding where, how, why, when, and under what conditions (environmental, physical, social, emotional) your product, service, or interface will be experienced or used. Getting context wrong or leaving it out can make or break a good design decision.
