1. A user centric policy creation and enforcement method comprising: observing state changes and action invocations in disparate applications through visual views of said disparate applications displayed by a computer system; demarcating segments of markup as segments which visually indicate said observed state changes in said disparate applications by parsing said markup defining the visual views of said disparate applications using a page crawler; establishing correlations between said observed state changes and action invocations; formulating rules in a policy based upon user selected ones of said established correlations, each of said rules specifying a state change in at least one of said disparate applications, and at least one resulting action invocation in at least one other of said disparate applications; and applying said policy to automatically respond to each subsequently observed state change with a specified action invocation.
