01
Visibility
Behavior is invisible
The intended behavior of a machine is not defined anywhere you can check — it is buried in code. No artifact carries behavior normatively.

How much of a BlackBox are your critical machines?
Most machine behavior is hidden in code — undocumented, vendor-dependent, and only visible once something breaks. Score your BlackBox risk in two minutes and see exactly where it sits.

01 — The problem
The problem hides
until it's too late.
When behavior lives only in the PLC code, you can't verify it and you can't hand it over — and you find out something is wrong after the damage is done.
02
Timing
Faults surface too late
You react to malfunctions instead of catching behavioral deviation first. The deviation comes before the fault code, not after it.
03
Dependency
Knowledge tied to people
A few key people and one control vendor hold the knowledge. Lose them, and control goes with them.
02 — What you get
A clear read
on your BlackBox risk.
Three pages, filled in two minutes. At the end there is no marketing copy — there is a number and a next step.
12 statements, 4 dimensionsVisibility, early warning, independence, and lifecycle and data — each dimension scored on its own.
A risk score out of 36Plus four subtotals that show where the risk concentrates — not just that it exists.
Four risk bandsFrom “mostly WhiteBox” to “critical”, each with what it means for your line.
Your next stepThe fastest way to turn the score into a plan — exactly one recommendation per band.
What the self-check does not do
It measures your own assessment, not your machine. It replaces neither a test nor an assessment — it shows where a test pays off first. What you do not score stays unscored.
03 — Who it's for
For plants with critical machines
where behavior matters.
Measured by downtime, OEE, TCO or asset value — anywhere the behavior of a machine moves a business result.
WhiteBox does not mean you can see the code. WhiteBox means conformity is decidable rather than a matter of judgment.
