In this paper we summarise, and attempt to unify, the many descriptions that have been published on general mode changes. We then use this summary to position the criticality mode change. We conclude that a criticality mode change (from low to high) is closest in nature to a (graceful) degradation mode change following (partial) system failure. However, a criticality mode change (from high to low) has more in common with a (exceptional) functional mode change. The paper also addresses systems that may have both criticality and general mode changes.
