Relationships Between Users, Responsibilities, Customization Packages, and Metadata Files
The responsibility that a customization package references creates a relationship between a Siebel CRM Desktop user and a Siebel CRM Desktop configuration. If the package is activated and published, then a user that the responsibility references can download the configuration that the package defines. This configuration is a collection of metadata files that Siebel CRM Desktop stores on the Siebel Server and downloads to Outlook during synchronization.
The example in the following image shows how several users (U1, U2, and U3) are related to several responsibilities (R1, R2, R3, R4, and R5), and how these responsibilities are related to several customization packages (P1, P2, and P3).

Responsibility. A Siebel responsibility, such as Sales Representative. It corresponds to the job role that the user performs.
Customization package. A collection of metadata files. Siebel CRM Desktop creates a relationship between these files and a responsibility. For more information, see About the Customization Package.
