From an analyst's perspective, vendors and customers in the online space have reached the point where they're talking past each other bigtime -- they're looking at the same world, but perceiving it very differently. Vendors continue to think they win business by focusing on features, while enterprises have shifted their selection criteria to execution.
It wasn't always that way. When a technology is in its early stages, features are everything -- they're the major differentiator for a vendor. For example, in the Web analytics space, in the late 90s -- when page tagging was rare and that's what a customer wanted -- WebSideStory could beat WebTrends handily in a competitive situation. WebSideStory had the feature, WebTrends didn't, and that was that.
