+# Separating Estimating Concerns
+
+> [!info] Separation of Concerns
+> Separation of concerns is a design philosophy
+> of eliminating unnecessary process coupling,
+> or in other words preferring specialization.
+> It is traditionally understood as a principle strictly of _software_ design,
+> however its applications are universal.

+In [[my-occupation]],
+
+## Ideal Workflow
+
+### 1. Annotation
+
+Annotation is documenting project scope as intended by its design.
+This involves reconciling missing and conflicting requirements,
+as well as erroneous and misplaced symbols.
+
+This process is intended to be _unbiased_, without respect for
+* industry knowledge
+* contractor standard practices
+
+The annotator is to describe the design scope
+without adding any outside information.
+
+#### Output
+
+The processes and tools for completing this step
+would differ between design-build and plans-and-specs projects,
+but the output would be identical in function.
+
+This step encodes "measures" with "tags"
+and describes the behavior of special tags
+(e.g. structure height of each `Level`)
+
+### ~~next step(s)~~
+
+Define takeoff given counts from step 1.
+
+```
+LET wiring-devices 'default/wiring-devices/decora'
+
+FOREACH MEASURE
+WHERE 'type' IS 'device/receptacle/duplex' AND 'mounting' IS 'flush'
+TAKEOFF 'DUPLEX REC - FLUSH IN METAL STUDS' FROM wiring-devices
