Squared Outline: Time-frames

Time-frames are defined by root events and therefore best defined along the same guideline, namely their scope and the nature of coupling. 

Along that understanding, time-frames can be defined with regard to context (symbolic or actual) and coupling (asynchronous or synchronous):

  1. Symbolic, no coupling: time-frames set by internal events, involving a single actor.
  2. Symbolic, coupling: time-frames set by external events, involving a single actor.
  3. Actual, asynchronous: time-frames set by external events, involving different actors without real-time constraint.
  4. Actual, synchronous: time-frames set by external events, involving different actors with real-time constraint.

That taxonomy could be used to align time-frames with processes‘ execution mode.
