Bounded Applicability

This is really a small one that I am putting in because it is the kind of thing that I will forget otherwise. Bounded applicability is a term that Dave Snowden uses to describe the limits that any tool, technology or method has. As the tool, technology or method approaches those limits, the cost/benefit ratio begins to become unappealing. Interesting but what’s the point? We tend to use the tool, technology or method more frenetically when really we ought to be recognising the "bounded applicability" of the tool/technology/method and step back to refresh our perspective.
