What do you like best?
Forrester provides some information about the industries and technology I need, but never full information.
What do you dislike?
Unfortunately reports by Forrester are not sufficient when it comes to knowledge about particular industries or technology. I'd expect the reports to be more thorough and detailed, especially on the smaller and mid-sized providers. Trustworthiness of reports is somewhat doubtful, as it seems only companies paying to partner with Forrester get featured in their reports.
