What it is

Forrester is the research and advisory firm George Colony founded in Cambridge, Massachusetts in 1983, differentiated by a customer-first research lens: the Customer Experience Index linking CX quality to revenue, the Forrester Wave vendor evaluations (criteria scores published in a downloadable model), and — through its 2019 SiriusDecisions acquisition — the B2B revenue machinery (the demand waterfall, the messaging nomenclature) that runs inside most B2B marketing orgs.

Why marketers rely on it

Two franchises matter to marketers. The CX research gives customer-experience investment a financial argument (the index correlates CX scores with growth). And the SiriusDecisions inheritance is quietly everywhere in B2B — if your org speaks 'MQL to SQL conversion' and stages its funnel as a waterfall, it's running on frameworks Forrester now owns. The Wave's published scoring model also makes it the more transparent of the big-two vendor ratings.

How to use it well

Use the Wave's downloadable scorecard to re-weight criteria for YOUR requirements (the published model invites it — re-rank with your weights before shortlisting). Use the CX Index method to argue experience budgets in CFO language, and the B2B frameworks as shared vocabulary — while remembering frameworks describe the average org, and yours isn't average.

Worked example. A B2B marketing leader inherits a funnel nobody can explain. The Forrester-school rebuild: adopt the demand-waterfall stages so sales and marketing finally share definitions, instrument conversion at each gate, and benchmark against the published norms. The diagnosis falls out in the data — healthy inquiry volume, catastrophic MQL-to-SAL handoff (sales never agreed to the MQL definition). Fixing the definition, not the ads, doubles accepted leads in a quarter — the framework's whole job was forcing the conversation.
Failure modes to watch. Reading the Wave bubble without re-weighting the published criteria for your context; installing the waterfall's stages without sales agreeing to the definitions; and citing CX correlations as causation for any pet project.
