There is a great interview with Coremetrics CEO Joseph Davis over at Mycustomer.com. A few quotes I really liked and for a lot of companies this statement is so true:
"We have an inherent advantage in the way that we deploy ourapplications in that everything is the same, we don't do customisation. So while Omniture can take months to deploy because they continue to customise and customise, our implementations are all the same. So if you're a retailer, then the implementation can be up and running and there are 60 or so reports sitting there waiting for you. So the ROI comes quicker".
