When we forget about the end-user, our design is likely to be flawed.  We no longer ask the right questions and adopt an empathetic mindset.  If we build a trail, open to hikers, bikers, and equestrians but leave overhanging boulders and rock slabs that cannot accommodate a horse and rider, we are saying ‘this is not really for you.’  The design may have been intended as accessible for multiple user groups, but the construction crew was not thinking about one of the user groups when they built the trail.

How might we avoid building for an end-user but forget to hold their needs above ours?  What is convenient during planning and construction might result in unnecessary barriers and frustration for the user.
