Sensors & data capture

Real numbers off the floor, automatically — so decisions stop relying on clipboards and memory.

Data capture means getting what's actually happening on the floor — output, downtime, counts, conditions — into your system without someone writing it down. Sensors are one way to do it. Done well, it replaces guesswork with live fact. Done for its own sake, it's expensive instrumentation no one ever looks at.

The case for sensors is simple: anything captured by hand is captured late, partially, and with a bias toward looking fine. Automatic capture is continuous and honest. That's the value — not the hardware, but the truth it produces.

Not everything needs a sensor, though. The ones that pay back measure something you'll act on: the machine that stops most, the count that drives a decision, the condition that precedes a failure. Instrumenting everything 'to have the data' is how budgets get wasted and dashboards get ignored.

Start from the decision you want to make better, then capture the minimum that informs it. The right few signals, live, beat a hundred you never look at.

The short version

  • Capture's value is honest, live data — not the hardware itself.
  • Sensor it if you'll act on it; skip it if it's data for data's sake.
  • Start from the decision, then capture the minimum that informs it.
  • Hand-written data is late and flattering; automatic data is neither.

Common questions

Do I need to replace my machines to capture data?

Usually not. Many machines can be read with add-on sensors, or with simple terminals for manual entry where automation isn't worth it. Wholesale replacement is rarely the starting point.

Which sensors are actually worth it?

The ones measuring something you'll act on — your most-stopped machine, a count that drives a decision, a condition that warns of failure. If a reading wouldn't change what you do, it's probably not worth instrumenting.
