Dynamics xRM
What is "xRM"? One way to look at it is that the “x” stands for extended, as in extended relationship management. The other way it to treat the “x” as a variable, meaning “anything” relationship management, such as patient/doctor relationship management, partner relationship management, constituent relationship management, employee relationship management, project relationship management, etc. Both views refer to building an application on top of the Microsoft Dynamics CRM platform. Building an xRM application can take the form of customizing the existing customer relationship management applications that are included in Microsoft Dynamics CRM, or by designing completely new line-of-business applications that are not based on the sales, service, or marketing capabilities included in Microsoft Dynamics CRM. The common thread to xRM is that your application will use the Microsoft Dynamics CRM as a platform, leveraging the capabilities of the platform to deliver business value to your users.

xRM applications can also include other Microsoft technologies, including SharePoint and custom code written using Microsoft Visual Studio development tools. xRM applications can be Web-based, desktop applications or both.
