Squared Outline: States

States are used to describe relevant aspects in contexts and how the changes are to affect systems representations and behaviors.

On that account, events and states are complementary: the former are to notify relevant changes, the latter are to represent the partitions (²) that makes these changes relevant. Transitions are used to map the causes and effects of changes.

  1. State of physical objects.
  2. State of processes’ execution.
  3. State of actors’ expectations.
  4. State of symbolic representations.

Beside alignment with events, defining states consistently across objects, processes, and actors is to significantly enhance the traceability and transparency of architectures designs.
