# What is "systems mapping"?

## The research claim

What people call systems mapping is a category error about the medium. The mapping is not the Miro board, the Visio file or the sticky notes: the mapping is the correspondence itself. Object-Oriented Thinking (OOT) is the underlying practice, DSRP-484 is what OOT is made of, and a systems map is what you get when the structure of a mental model is carried into a medium one-to-one. Because DSRP is itself object-oriented, it is what lets the correspondence hold at all.

## What would confirm it

A mental model (M) is information organized (IO) by the four patterns. Systems mapping is the act of carrying that organization into some medium (X) without losing or inventing structure, so the map and the thought have the same shape. The residual (rho, what is left over with nowhere to go) is zero at both ends. What makes it worth doing is the loop back to reality: you build the object so you can check the model against the world and fix it.

## What would refute it

Some of what organizes these objects is not distinctions, systems, relationships or perspectives, and needs something else to describe it. Or people make them for reasons that have nothing to do with checking their thinking against reality.

## The evidence, and why this status

Coffman's systematic review assembled 51 publications on structured external representations from adjacent literatures, without DSRP, MIO, RIO or LRL vocabulary, and explicitly declines to validate OOT. Coded against that corpus: all 65 organizational features in the 34 papers carrying explicit organization evidence were representable in DSRP or combinations of its patterns, residual 0/34, one-sided 95 percent upper bound 8.4 percent. No core purpose among the 32 papers with a linked purpose claim fell outside direct or enabling LRL functions, 0/32, bound 8.9 percent. A full-text replication of all 51 papers extracted 5,735 verbatim statements, coded blind: 94.8 percent of organization statements sit inside the four patterns, 93.4 percent of purpose statements inside the LRL, feedback and fitback co-occur at an odds ratio of 3.38, and 46 of 51 papers satisfy both conditions independently.
