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.
