I’m not one to usually plug Oracle (Siebel) products, but in this case there’s a decent white paper available to download for free. All you need to do is fill out a looong form and they’ll email you a link to the report. I’d provide a direct link if I could but you know I legally can’t do that. 🙁 Here’s a description from their page:
Find out if an on-demand service or on-premise application is the right CRM deployment option for your business.
“Certain vendors preach the software deployment model du jour as the only sure-fire path to CRM success before understanding your business requirements. Selecting the right deployment model must first and foremost address your key business problems and challenges, enabling you to meet your strategic business goals. The more you know the pros and cons of each deployment model, the more certain it is that you will embark on a path to CRM success.”
