All TestStand process models identify UUTs and display UUT status information. Process models also call process model plug-ins that generate reports and log results to databases or files.

You can use client sequence files to customize various process model operations by overriding model-defined callback sequences. You can also create or modify process model plug-ins to add or modify functionality.

Process models provide Configuration and Execution entry points for configuring model settings and running client files under the model. Each entry point is a sequence in the process model file. The Configure and Execute menus of an application typically include the model entry points.
