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 certification and audit volumes. Certificate-issuance counts published by national accreditation bodies for ISO 9001, ISO 27001, ISO 14001 and the other standards in scope are combined with average audit-day pricing and typical audit-day counts per certificate by organization size, then extended to surveillance and renewal audit cycles that recur through a certificate's multi-year validity. This produces a bottom-up revenue figure for certification-body activity. That figure is checked against disclosed revenue from the largest listed and privately reporting certification bodies; where a check disagreed with the bottom-up total, the correction was made to the underlying audit-day or pricing assumption driving the bottom-up build, not by blending in the disclosed figure directly.

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 target commercial and quality-management roles that decide which certification body a company hires: heads of quality and compliance at certified organizations, business-development leads at certification bodies, and accreditation-scheme staff who track scheme volumes and fee schedules. Procurement and supply-chain roles at large buyers that mandate supplier certification are included to gauge how certification requirements are set as tender conditions. Sampling weights North America and Europe, where certification density is highest and disclosure is most complete, with additional coverage in China and India to capture the manufacturing base driving the fastest volume growth outside those two regions.

Secondary sources, this report

Desk research draws on national accreditation body registers (UKAS, ANAB, DAkkS and equivalents) that publish accredited certificate counts by standard and by country, the ISO Survey of certifications, International Accreditation Forum multilateral recognition arrangement listings, and public filings from the listed certification and inspection groups that disclose a testing, inspection and certification segment. Trade-body benchmarks from national standards institutes on certification fee ranges by organization size supplement the accreditation registers where certificate counts are not broken out by revenue.

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 carries forward the certificate-renewal cycle built into the base year and layers in the pace at which data-security and supply-chain certification mandates are being written into customer contracts and public procurement conditions. Pricing is held roughly flat in real terms, since certification fees move with auditor-day rates and not with demand surges. The main assumption tested is how quickly small and medium enterprises take up certification once a large buyer requires it of its supplier base; a slower uptake curve than assumed here would shift volume toward later years without changing the destination.

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 certificate-count growth by standard over the last five years to confirm the forecast curve does not imply a pace of adoption faster than what accreditation bodies have already recorded. Segment-level shifts, particularly the move toward information-security certification, were checked against accreditation-body scheme growth instead of taken on assumption. Sensitivities were run on audit-day pricing and on the pace of remote-audit adoption, since both affect revenue per certificate without changing certificate counts themselves.

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 highest for ISO 9001 and ISO 27001 volumes in North America and Europe, where accreditation-body registers publish certificate counts directly. It is lower for organization-size splits and for audit-mode splits, since few registers break out remote versus on-site delivery, so those shares rely on certification-body commentary instead of a published count. The main risk to the forecast is a change in how quickly accreditation bodies approve remote-evidence gathering for surveillance audits, which would shift revenue between the on-site and remote lines without changing the total.
