Systems Processes Theory (SPT)

The SPT is an ongoing unification of many systems theories and much systems-level research into one comprehensive and very detailed general theory of systems. SPT stresses the mechanics of how sustainable systems WORK. What they do to remain stable. SPT also involves integrating past systems insights and findings from 7 historical developmental phases of systems research with the conventional natural sciences literature that studies phenomena of natural processes. We maintain that each of the natural phenomena is an instance of a systems and so studying natural phenomena (even via reductionist science) yields factual information important to understanding “systemness.”

Since there are between 80 and 110 specific ISP’s (Isomorphic Systems Processes) in SPT, and so at least 80 sub-sub buttons, we have dedicated a two entire websites to delivering that mountain of information. It is not included here; this website is only for an introduction to that Troncale Lifework.

The first website below, displays research articles, powerpoints, posters, editorials and essays I have written on these particular systems processes or commentaries or on development of the entire field of systems science. Here for my Lifework you will only find information on the specific ISP’s I have researched directly. For specific subheadings for each Isomorphic Systems Process (ISP) of the Systems Processes Theory (SPT) (that I have identified, collected, & worked on for the last half century) please go to the following website:

It has sections that describe each of the 110 or more main systems processes, definition of systems processes, and the chief contribution of SPT, definition and lists of Linkage Propositions that describe the important mutual influences of systems processes on each other. It is this feature that makes the SPT Unified Theory one step more complete than most theories. It is the interlocking net of SP’s via LP’s is a network system itself at both the most general level of explanation and the most detailed level of explanation at the same time.
