Reduction in unplanned downtime on covered equipment

65%

  • Roughly £4m a year in lost production to unplanned downtime before the programme
  • Diagnostic phase found around 70% of unplanned downtime concentrated in 12 machines, with failure patterns detectable up to 14 days in advance from existing sensor data
  • Unplanned downtime fell by approximately 65% on the equipment covered by the predictive models in the 12 months following deployment
  • The original business case projected £2.5m in annual savings; actual measured savings came in higher, at £2.8m
  • Plant managers report using the operations dashboard daily, described as unusual for an analytics deployment of this kind

The problem

A UK heavy industrial manufacturer operating four production sites was losing approximately £4m a year in lost production to unplanned equipment downtime. This was not, in the conventional sense, a data-collection problem: the business had already fitted sensor packages to its critical machinery as part of an earlier digitalisation programme. The telemetry existed but sat largely unused in a data lake, generating no operational insight and no change in maintenance behaviour.

This is a common failure mode in industrial analytics: instrumentation is treated as the deliverable, when the thing that actually reduces downtime is a decision an engineer or plant manager can act on before a machine fails. Without a translation layer between sensor data and the maintenance workflow, investment in sensors does not, on its own, reduce downtime or lost production.

How we delivered it

  1. Two-week diagnostic

    Before building anything, identified which machinery was actually driving the downtime and whether existing sensor data contained a usable failure signal, rather than assuming a plant-wide fix was needed.

  2. Target the highest-impact equipment

    The diagnostic found that around 70% of unplanned downtime was concentrated in 12 pieces of equipment, and that failure patterns on those machines were detectable up to 14 days in advance from data already being collected.

  3. Build failure-prediction models for the 12 priority machines

    Models were built only for the equipment identified as driving the bulk of downtime, using the sensor streams the manufacturer already had rather than commissioning new instrumentation.

  4. Integrate predictions into the existing CMMS

    Predicted failures generated maintenance tickets inside the plant's existing maintenance management system, so engineers received them in their normal workflow rather than a new standalone tool.

  5. Build an operations dashboard for plant managers

    A single view combining equipment health, throughput and predicted issues was built for plant management use, rather than a periodic report.

  6. Measure delivered outcomes against the original business case

    Downtime reduction and pound-value savings on the covered equipment were tracked over the 12 months following deployment and checked against the projections in the original business case.

  1. Existing sensors

    Telemetry already being captured on critical machinery from an earlier digitalisation programme, previously sitting unused in a data lake.

  2. Two-week diagnostic

    Identified that ~70% of downtime was concentrated in 12 machines, with failure patterns predictable up to 14 days ahead.

  3. Failure-prediction models

    Built for the 12 priority machines, using the sensor streams already being collected.

  4. Existing CMMS

    Predicted failures generated maintenance tickets inside the plant's normal maintenance workflow.

  5. Operations dashboard

    Equipment health, throughput and predicted issues combined into one view for plant managers.

From unused sensor data to a daily-used maintenance decision: diagnose, predict, then route into the tools people already use.

Built with

  • Sensor telemetry / data lake (pre-existing)

    Source data from an earlier digitalisation programme; previously collected but unused for decision-making

  • Failure-prediction models

    Forecast failure on the 12 priority machines up to 14 days in advance, built on the existing sensor streams

  • CMMS (Computerised Maintenance Management System, pre-existing)

    Received predicted-failure tickets inside the maintenance team's normal workflow

  • Operations dashboard (custom-built)

    Single view of equipment health, throughput and predicted issues for plant managers

Reduction in unplanned downtime on covered equipment

What was delivered

  • Roughly £4m a year in lost production to unplanned downtime before the programme
  • Diagnostic phase found around 70% of unplanned downtime concentrated in 12 machines, with failure patterns detectable up to 14 days in advance from existing sensor data
  • Unplanned downtime fell by approximately 65% on the equipment covered by the predictive models in the 12 months following deployment
  • The original business case projected £2.5m in annual savings; actual measured savings came in higher, at £2.8m
  • Plant managers report using the operations dashboard daily, described as unusual for an analytics deployment of this kind

How a return would be measured

The saving is the reduction in unplanned-downtime cost, measured on the twelve covered machines over the twelve months following deployment. The source states the original business case projected £2.5m in annual savings and that actual measured savings came in at £2.8m; it does not specify whether the two figures share an identical measurement basis. The £2.8m figure is presented here only as the measured outcome the source states, not a re-derived or annualised estimate, and no new calculation has been introduced.

An unplanned-downtime bill of roughly £4m a year rarely comes down to a missing sensor. This UK heavy industrial manufacturer, running four production sites, already had sensor packages fitted to its critical machinery from an earlier digitalisation programme. The telemetry existed. It simply sat in a data lake, unused, generating no decisions and no change in maintenance behaviour. That gap, between data collected and data acted on, is where the engagement began.

Rather than start by building models across the whole estate, the first two weeks were spent on diagnosis: which machines were actually driving the downtime, and whether the existing sensor streams contained enough signal to predict failure before it happened. The answer narrowed the problem considerably. Around 70% of the manufacturer's unplanned downtime was concentrated in just 12 pieces of equipment, and failure patterns on those machines were detectable up to 14 days in advance from data the business was already collecting. That single finding reframed the project: rather than instrumenting the whole estate, the task became predicting failure on the twelve machines that actually mattered.

Failure-prediction models were built for those 12 assets, using the existing sensor streams rather than commissioning new hardware. The harder design problem was not the modelling but the delivery: a prediction is worthless if it lands somewhere nobody looks. So the predictions were fed into the manufacturer's existing CMMS, generating maintenance tickets inside the tool engineers already used, rather than a new standalone system competing for attention. Alongside this, an operations dashboard was built for plant managers, bringing equipment health, throughput and predicted issues into a single view rather than the scattered reports that typically accompany sensor deployments of this kind.

That workflow choice, prediction into an existing tool rather than a new one, appears to be the reason the deployment stuck. Plant managers report using the dashboard daily, which is an unusual outcome for an industrial analytics tool; most such dashboards are checked occasionally, if at all, once the novelty wears off.

The results bear out the approach. Over the 12 months following deployment, unplanned downtime on the twelve covered machines fell by approximately 65%. The original business case had projected £2.5m in annual savings; the actual measured saving came in higher, at £2.8m. That gap between projection and delivery is worth noting in its own right: it suggests the diagnostic-led targeting of the highest-impact machines, rather than a blanket rollout, captured more value than the initial model assumed.

The wider lesson for manufacturers sitting on unused sensor data is that the constraint is rarely the data itself. It is usually the translation layer: turning telemetry into a specific, targeted prediction, and routing that prediction into a workflow people already use, rather than adding another tool to check. A two-week diagnostic that narrows a plant-wide problem down to a dozen machines is cheap relative to guessing at scale, and it is also what let a targeted, well-integrated deployment outperform its own business case.

For manufacturers considering a similar programme, the sequence here is repeatable: audit what sensor data already exists before commissioning anything new; diagnose where downtime actually concentrates rather than assuming it is spread evenly; build prediction models only for the highest-impact assets; and integrate outputs into the maintenance and management tools staff already use, so adoption does not depend on habit change. The measurable outcome, a 65% cut in downtime and savings ahead of the original business case, followed from getting that sequence right rather than from any single piece of technology.
