Methodology

How the estimates were built: data sources, modelling approach and validation steps.

Research approach

A market size is a claim about the world, and a claim is only as good as the route to it. Every study is built upward from units and prices — what is actually produced, sold or performed, at what it actually changes hands for — rather than from a headline figure divided downwards. Disclosed company revenue is then used to check that build, not to produce it.

Market size estimation, this report

The estimate is built upward from the installed base of control and automation systems in service globally: units of distributed control, SCADA, programmable logic control and manufacturing execution system deployments by end-use industry, multiplied by the realised price of the engineering, installation, maintenance and consulting work sold against each. Service attach rates per installed unit and average contract values by technology type are the inputs that carry the build. The resulting figures are checked against the disclosed automation and services revenue of the major listed suppliers named in this report; where an input, most often a service attach-rate assumption for a smaller technology category, ran ahead of what these disclosures implied, the bottom-up assumption was corrected rather than the two figures averaged.

The four stages

The same sequence runs behind every published study, whatever the industry. The order matters as much as the steps: the segment axes are fixed before any number is collected, so the model is never reshaped to fit whatever data happens to turn up.

What the build rests on, and what checks it

The two are not interchangeable. The left column produces the number; the right column tests it. When the check disagrees with the build, the answer is to find which bottom-up assumption is wrong — a unit count, a price, a take-up rate — not to split the difference between them.

The bottom-up build rests on
  • Volume actually transacted — units produced, installed, dispensed or procedures performed, counted at the level each is genuinely recorded
  • Realised pricing by tier and channel, rather than one blended average applied across the whole market
  • Take-up and frequency: how much of the addressable base buys, and how often it repeats
The build is checked against
  • Disclosed revenue of the companies serving the market, where filings separate it far enough to be usable
  • Buyer-side spending totals — capital budgets, procurement lines, or the output of the end market the product is bought against
  • Trade and customs flows, where the product crosses borders in a separately recorded form

Data sources

Published data establishes what happened. Only the people transacting in a market can say why, and what is about to change — so the two are collected separately and weighted differently.

Primary — who is interviewed
  • Commercial and product leadership at the companies that supply the market
  • Procurement and specification leads at the organisations that buy it
  • Distributors, integrators and channel partners, where the market is served indirectly
  • Regulatory and standards specialists, where approval governs what can be sold at all
Secondary — what is read
  • Company filings, annual reports and investor disclosure
  • Government statistics, customs records and regulatory registers
  • Trade association output and standards-body publications
  • Technical and peer-reviewed literature, where the market rests on a clinical or engineering claim
Primary research design, this report

Interviews are directed at the roles that actually decide and administer automation service spend: plant engineering and operations managers who scope projects, procurement leads who negotiate service contracts, systems integrators and channel partners who deliver the work, and, where relevant, plant safety or regulatory-compliance officers who set requirements for process industries. Sampling is weighted toward North America, Western Europe and the manufacturing centers of East Asia, where automation service spend is concentrated and where integrator and end-user contacts are most reachable, supplemented by a smaller sample from the faster-growing manufacturing hubs of South and Southeast Asia to capture the emerging-market adoption pattern described in this report.

Secondary sources, this report

Desk research draws on customs trade data filed under the harmonized system codes covering industrial control equipment, national manufacturing output and capital expenditure statistics published by statistical agencies including the U.S. Census Bureau and Eurostat, and safety and product certification listings maintained by UL and the IEC for control and automation hardware. Trade-body benchmarks from the International Society of Automation and the ARC Advisory Group's published market commentary are used to cross-check technology-type splits, and the financial filings of the major listed suppliers named in this report anchor the top-down revenue check described above.

Desk research runs across proprietary research databases including Factiva, OneSource and Hoovers alongside the public sources above. Modelling and statistical validation are run in SAS and SPSS.

Forecasting

The forecast is not a growth rate applied to a base year. It is built from the drivers that are expected to change, each one stated so a reader can disagree with it.

Forecast approach, this report

The forecast is built from projected capital spending on new automation projects, the replacement cycle of aging control systems already installed, and the pace at which manufacturers shift service spend from one-time installation toward ongoing operational and maintenance contracts. Regional manufacturing capacity expansion plans, particularly across Asia Pacific and India, and the adoption curve for cloud-connected monitoring are the two assumptions that move the forecast most. It normalizes for the unusually depressed capital spending manufacturers reported in 2020, treating that year as a temporary trough, not a new baseline. The forecast holds if manufacturing capital investment continues at a pace broadly consistent with the last five years.

Triangulation and validation

No figure enters a report on the strength of one source. Where the two sizing routes disagree the difference is not averaged away — the assumption causing it is isolated, tested against a third independent measure, and either corrected or carried forward as a stated limitation. Historical years are back-tested against the growth actually recorded before any forecast is allowed to run forward from them.

Validation, this report

Outputs are back-tested against recorded automation capital spending and service revenue growth reported by the listed suppliers named in this report over the historical period, checking that the modeled 2020-2024 trajectory tracks what those companies actually reported. Segment-level shifts, including the move toward manufacturing execution systems and operational services, were reviewed against the same primary interviews described above rather than assumed outright. Sensitivities were tested on the two forecast assumptions that move the estimate most: the pace of manufacturing capacity expansion in Asia Pacific and the rate at which cloud-based deployment displaces on-premise systems, to confirm the forecast holds under a slower adoption path.

Confidence and limitations

Where an estimate is firm and where it is not is stated rather than left to be inferred from the precision of the number.

Confidence framing, this report

Confidence is firmest for programmable logic control and distributed control system revenue, where the installed base and supplier disclosures are both well documented, and for the automotive and oil and gas end-use estimates, which rest on long-published capital spending series. It is thinner for manufacturing execution system and operational-services revenue in small and medium enterprises, where reporting is sparser and adoption is still forming. A structural risk worth naming is a sharp pullback in manufacturing capital spending, which would slow the replacement cycle this forecast assumes continues at a broadly steady pace.
