Field Service Application Design
Siebel Field Service operates as a single Windows NT service that runs components such as EIM, Optimization Engine, Assignment Manager, and so on. Siebel Server operates components as processes or threads based on the system preferences specified for each component. Thus, there can be multiple components running at the same time and each component can run a specified number of tasks at a given time.
