# Proactive Service Experience Workflows architecture

There are multiple components that make up the architecture of the Proactive Service Experience Workflows application.

The main components are as follows:

-   Flows and subflows
-   Escalation stages
-   Decision tables
-   Messages
-   Business rule
-   Client scripts
-   System properties
-   Roles
-   Assignment groups
-   Service Operations Workspace

## Decision tables

Based on the defined condition, Workflow Studio works with the Incident Escalation Policy \[sys\_hub\_flow\] decision table to determine which subflow to generate at certain escalation points.

## Messages

Each subflow in Proactive Service Experience Workflows is associated with a message file that provides instructions for agents to use to troubleshoot, escalate, and resolve network-initiated incidents. For more information about how to customize the default instructions for your internal troubleshooting processes, see [Customize message files](../task/configure-msg-file-taw.md).

## Roles

The `sn_ind_tsm_core.noc_agent` role is available with the Proactive Service Experience Workflows application. This role when added, ensures that the technical support agent can see the relevant information between ITSM and CSM applications. This role includes the following:

-   itil
-   wm\_initiator
-   wm\_read
-   sn\_customerservice.case\_viewer
-   sn\_customerservice.customer\_data\_viewer

Several assignment groups are included with this role and other groups can also have the admin role. The `sn_ind_tsm_sdwan.ticket_integrator` role can be used for trouble tickets created from the TMF 621 Open API use cases.
