With the success of software-as-a-service (saas) based vendors such as Salesforce.com and NetSuite, more and more applications are being accessed over the Web.  In fact, Nucleus is finding that applications once thought to be too proprietary or mission critical for saas, such as ERP, are increasingly being delivered as a service.  Given increasing rates of saas adoption, as well as current pressures to accomplish high-ROI deployments, Nucleus decided to examine the user base of saas vendor NetSuite.  NetSuite provides an on-demand platform that includes ERP, financials, e-commerce, and analytics.  The suite is designed to both provide applications that are interoperable out of the box and to enable better sharing of data among departments and applications.
