The Forrester Wave Methodology
A Forrester Wave is a guide for buyers considering their purchasing options in a technology marketplace. To offer an equitable process for all participants, Forrester follows to evaluate participating vendors.
In our review, we conduct primary research to develop a list of vendors to consider for the evaluation. From that initial pool of vendors, we narrow our final list based on a small number of inclusion criteria. We then gather details of product and strategy through a detailed questionnaire, demos/briefings, and customer reference surveys/interviews. We use those inputs, along with the analyst's experience and expertise in the marketplace, to score vendors. In accordance with the , Forrester asks vendors to review our findings prior to publishing to check for accuracy.
We include the Forrester Wave publishing date (quarter and year) clearly in the title of each Forrester Wave document. We evaluated the vendors participating in this Forrester Wave using materials that they provided to us by August 24, 2018, and did not allow additional information after that point. We encourage readers to consider how the market and vendor offerings change over time.
Vendors marked as nonparticipating vendors in the Forrester Wave graphic met our defined inclusion criteria but declined to participate in or contributed only partially to the evaluation. We score these vendors to the best of our ability according to our and publish their positioning along with participating vendors.
