As I understand there is a close interrelationship between the two in
that they are seeking to understand inter-dependencies. Context design
is a term used to describe the process of creating models of parts and
assemblies within the context of other parts and assemblies. The
language of context design is that of components and discrete elements
It is concerned primarily with local adjacencies--elements that will
have an immediate impact.
Whole systems design is concerned with the broader relationship of
system components and the ways in which components, and problems
resident within described systems, which on face value are not
directly connected but may have a profound impact on each other. The
language of whole systems design is that of stocks, flows and movement
through and across the system. It has a behavioral bias.
