Change impact before sustainment work
Establish what depends on a machine tool or control system before it is isolated, replaced, or upgraded.

When a depot line stops, readiness is what is delayed.
Sustainment work depends on equipment installed across decades, in facilities that cannot admit the tools normally used to explain it.
01 · OPERATING CONDITIONS
Depots, shipyards, and aerospace manufacturing and repair operations run machine tools, test equipment, and material handling installed over long service lives and maintained well past original expectation. Work is scheduled against readiness commitments rather than commercial demand.
The constraints that protect these facilities also limit what can be learned about them. External connectivity is frequently prohibited, and so is software installed on control equipment, which leaves the operating account least available in the place it matters most.
02 · THE DEPENDENCY PROBLEM
Equipment is replaced, bypassed, re-cabled, and re-purposed across decades of sustainment. Each change is reasonable on its own, and each moves the operation further from the drawing that describes it.
The consequence appears at the moment of change. A component is isolated for maintenance, replacement, or upgrade, and a capability elsewhere in the facility stops for reasons that were never written down.
03 · WHAT NEUROPATH ESTABLISHES
An account of the operation as it is running.
Equipment in operationThe devices communicating on the production network, including equipment no current record accounts for.
Communication relationshipsWhich systems exchange information with which, and in what direction.
Timing patternsThe intervals and sequences that characterize normal operation for a given cell, line, or unit.
Operational dependenciesThe working relationships that determine what is affected when one system changes.
04 · PRIORITY USE CASES
Three questions this answers first.
Authoritative equipment account
Establish and maintain a current account of operational technology on the production network in a facility that cannot install software to obtain it.
Recurring throughput interruption
Examine the recorded sequence surrounding a repeating condition that interrupts a value stream.
05 · DEPLOYMENT CONSTRAINTS
Built for the constraints, not adapted to them.
No software on control equipmentNo external connectivity requiredNo inbound path to controlOperates within the plant boundaryContinues through loss of connectivity
Observation is passive. NeuroPath reads communications already present on the network and does not introduce traffic to the equipment it observes.
06 · FIRST ASSESSMENT
One system. One boundary. One written result.
A first engagement establishes the equipment, communications, timing, and dependency account for a single production or maintenance value stream, delivered as a written result that the facility's own engineers review against what they know.
Scope expands only when the operating question and the observed coverage justify the additional context.
07 · SECTOR EVIDENCE
The condition is documented.
The Government Accountability Office found that equipment exceeded its expected useful life at 15 of the 21 military depots it reviewed, and connected depot conditions to maintenance performance and readiness.
NIST identifies a complete and accurate inventory of operational technology as foundational to risk management, and advises caution with active scanning on operational networks because of its potential effect on device stability and safety.
