- The entity is able to exert purposeful active behavior (Rosenblueth, Wiener & Bigelow, 1943) to continuously adjust their functions in order to compensate for foreseen and/or unpredicted changes in its execution environment. This corresponds to the first part of Sachs’ definition: “Being at work.”
- As a result of the above behavior, the entity is able to retain their “identity” — namely their peculiar and distinctive functional and non-functional features — in the face of the above mentioned conditions, actions, and changes, and despite the adjustments carried out by the entity so as to improve its system-environment fit. This refers to the second part of Sachs’ definition: “Staying the same”.
