For security purposes, we model software and hardware systems, in particular, because it enables us to subject the systems to theoretical stress, understand how that stress will impact the systems before they are implemented, and see the systems holistically so we can focus on vulnerability details as needed. We also recognize that while the model and the final outcome may differ, having a model will always help understanding nuances and details relevant to the process of making and building. It is easier and cheaper to make changes to that schematic, and change the ways these pieces interact, than to move walls, frames, screws, engines, floors, wings, firewalls, servers, functions, or lines of code, after the fact. Humans create models because it is easier to visualize changes on a schematic, smaller scale than to embark on construction right away.

Humans create models to plan ahead or to decide what resources might be needed, what frameworks need to be put in place, what hills need moving, what valleys need filling, and how independent pieces will interact once put together. The church looks very different from the plan. Gall, currently recognized as the oldest preserved 2D visualization and plan of a building complex.

It was more like a ‘two-dimensional meditation on the ideal early medieval monastic community.’” 1 Such is the purpose associated with the Plan of St. At some point, one turns to the others and says, “Well, listen, it was not a plan per se.
