Paradigm is any set of rules or regulations that
will do two things - (a) they establish boundaries; and (b) these
rules and regulations tell us how to be successful by solving problems
within these boundaries.
Paradigms dramatically affect our judgments and our decision making
by influencing our perceptions. They filter incoming experience.
We constantly select from the world the data that best fit our rules
and regulations and try to ignore the rest. This is the paradigm
effect.
A paradigm shift is a revolutionary new way of
thinking about old problems - a dramatic collective change in our
perception, e.g. from "main-frame computers" to "desktop
computers". A paradigm shift usually occurs when the established
"rules of the game" fail to provide effective solutions
to our problems. A new insight, an alternative explanation or a
discovery provides perspective which revolutionizes our understanding.
When the old framework gives way to the new, a paradigm shift has
occurred.
