Essences of Interaction
controllable by design and implementation of a capability that mitigates ice
formation. Boundary conditions mediate the flow of EMMI across interfaces
at boundaries.
Boundary conditions can be defined as mediation of capabilities that enact
across boundaries. Consider a flow of EMMI between two objects, one defined
within a bounded systems, the other left undefined (and therefore not included
within the boundary of the bounded system). Describing the conditions which
determine the interaction between these two objects are equally acceptable as
boundary conditions. How those conditions exist, how those conditions apply,
and how those conditions affect EMMI at the boundaries are boundary conditions. Boundary conditions are a way of limiting how EMMI affects a bounded
object. It is most often boundary conditions that drive usage of bounded systems—how those systems can be operated, how they interact with objects and
systems that are outside their boundaries, and how the users of such systems
need to behave to accomplish their intended tasks.
Boundary Extenders
The interaction between two objects results in the enabling and use of
function(s). Should that use be transferable from one object to another, the
boundary for that function is extendable by that use. The condition to extend
a boundary (or to not extend a boundary) is the boundary condition. To
extend the boundary means to allow the object’s EMMI to be transferred (or
otherwise extended). The boundary of the object’s functional domain is
reached when the use that originated with the user and the object remains
unused, that is, the end of the function’s use (or appropriately, the end of the
lifecycle of the function or the end of stability for the function). The behaviors of people (generally users and stakeholders) that result because of the
objects or use(s) of the object are similarly bounded by the lifecycle of kindred behaviors.* If the originating object were to be destroyed, the function
would necessarily cease, while the behaviors might or might not continue.
The limit of influence of an object is reached when the receiving object’s
mechanism transforms input EMMI into an output that is related to but not
distinguishable directly from the original object’s output EMMI. In other
words, the receiving object’s behavior would appear indiscernible from that
which would be expected given a variety of inputs. In essence, the transformation of input EMMI into output EMMI that occurs from object to object
results in a change in the EMMI from object to object.
* More accurately, it is more than the mere uses of the object, but also behaviors that occur due
to the object or in anticipation of the object.
