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 market was built upward from the number of active multi-vendor IT estates under formal coordination and the realised annual contract value per estate, split by service type: integration and orchestration, service desk, service-level governance, compliance oversight and multi-vendor consulting. Estate counts were estimated from large enterprises running three or more concurrent IT suppliers, checked against outsourcing contract registers and public tender awards in regulated sectors. Average realised pricing per estate came from disclosed managed-services contract values. This bottom-up build was then checked against the service-integration revenue IBM, DXC Technology, Capgemini and Wipro report in their own segment filings; where the two diverged, the estate count or per-contract pricing assumption was corrected, not averaged against the disclosed figure.

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 the roles that decide a SIAM contract: IT sourcing and vendor-management leads who own the multi-supplier relationship, service delivery managers who run day-to-day escalation across providers, procurement leads who set contract structure and pricing, and compliance or risk officers in regulated sectors where governance requirements shape scope. Sampling weights North America and Europe most heavily, reflecting where formal SIAM operating models are most established, with a growing share of interviews in Asia Pacific to capture enterprises moving from informal to formal multi-vendor coordination. Channel and systems-integrator partners are also sampled to cross-check how sub-contracted work is priced and reported within larger managed-services engagements.

Secondary sources, this report

Desk research draws on IT outsourcing contract registers and public tender award databases in regulated markets, ITIL and SIAM Foundation body-of-knowledge benchmarks published by Scopism and AXELOS, segment disclosures in the 10-K and annual filings of the major listed providers named in this report, and national statistics agency data on business IT spending by sector. Regulatory registers relevant to BFSI and healthcare outsourcing, where SIAM adoption is most advanced, are checked directly rather than through secondary summaries. Gartner and ISG advisory commentary on managed-services contract volumes is used to sense-check estate counts, not as a standalone sizing input.

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 the pace at which enterprises with three or more IT suppliers move from informal coordination to a funded, formally governed SIAM model, and from the rate at which existing SIAM contracts shift from on-premise tooling to cloud-delivered orchestration platforms. Pricing is assumed to hold roughly flat in real terms as competition among integrators keeps per-contract rates from rising with volume. The forecast normalises for the unusually low base most providers reported through 2020 and 2021, when many outsourcing decisions were deferred rather than cancelled. For the forecast to hold, enterprise IT supplier counts need to keep rising rather than consolidate back toward single-vendor outsourcing.

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 were back-tested against each segment's recorded 2020-2024 growth to confirm the forecast does not imply an implausible break from recent trend. Segment share shifts, particularly the move from service desk management toward integration and orchestration spend, were reviewed against how providers describe their own service mix in recent earnings commentary. Sensitivities were run on the pace of cloud migration within deployment mode and on the share of large enterprises adopting a multi-vendor rather than single-vendor SIAM model, since both assumptions move the forecast more than any single driver. The regional split was checked against the ratio of large enterprises headquartered in each region relative to its share of global IT spend.

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

The estimate is firmest for BFSI and IT and telecom, where outsourcing contracts and supplier counts are documented in public filings and tender records. It is weaker for Others and for small and medium enterprise adoption, where informal or bundled coordination arrangements are rarely reported separately from general IT services spend, and the historical base for 2020-2021 relies more heavily on proxy indicators than on direct disclosure. A structural risk to the forecast is enterprise consolidation back toward single-vendor outsourcing, which would slow multi-vendor SIAM demand faster than the current trajectory assumes.
