The gap between ambition and installed base
Indian manufacturing has no shortage of Industry 4.0 ambition. Board decks reference predictive maintenance, digital twins, and lights-out production. Walk the same company's shop floor and you will often find controllers a decade past end-of-life, data trapped in machine-local memory, and a maintenance team keeping things alive on institutional knowledge.
That gap is not a failure of intent. It reflects the fact that most plants were built to run, not to report, and retrofitting visibility into a working line is a fundamentally different problem from designing it in.
02
Why the pilot usually stalls
The common pattern is a successful pilot on one line that never becomes a rollout. The pilot works because it gets disproportionate attention and a bespoke integration. The rollout stalls because that integration does not generalize — every additional machine speaks a different protocol, exposes different tags, and needs another custom bridge.
The fix is unglamorous: settle the data model before scaling the hardware. Define what a machine, a batch, and a fault mean across the plant, then make each integration conform to that model rather than inventing its own.
03
Where the returns actually appear
In our experience the first real return is rarely predictive maintenance. It is far more often energy sub-metering and downtime attribution — two things that require modest instrumentation and immediately change decisions.
Once a plant can say which line, shift, and product consumed what, and why the line stopped on Tuesday, the case for deeper investment makes itself with numbers the finance team already trusts.
