Simple and
Easy are not mutually exclusive. When simplicity is maximized, easiness should be pretty high. However, it is possible that maximizing easiness can significantly reduce simplicity.
A key part of a process or system being
Easy is that it also appears easy. That is why the definition is about presenting solutions quickly or nearby, as these are ways solutions can appear easy to us.
This can make involved parties more readily convinced of the benefits of
Easy solutions, even though there may often be an increased
Burden of Maintenance compared to a less
Easy but more
Simple solution.
