Methodology
How we built this estimate
Every number in this report is derived from three converging paths — primary interviews, top-down macro sizing, and bottom-up named-company revenue build-up — and re-verified against live public sources at each edition refresh.
-
Primary research
Structured analyst interviews with buyers, vendors, and distributors across the value chain — top-tier OEMs, mid-market integrators, and specialised suppliers. Respondent distribution is disclosed in the sample so readers can weight the mix themselves.
-
Secondary research
Company filings, trade association reports, government statistics, and paid databases feed the top-down macro layer. Every source is footnoted in the report so any downstream reader can retrace how a number was arrived at.
-
Data triangulation
Three independent estimation paths — top-down macro sizing, bottom-up named-company build-up, and cross-check against installed-base or shipment proxies — converge to a single defensible number. Divergences greater than 8% trigger a re-review.
-
Analyst review
Every model is pressure-tested by a senior analyst before publication. Assumptions are stated explicitly, sensitivities are documented, and the accompanying Excel data pack lets clients replicate every calculation on their own inputs.
