User interface concepts
People interact with workflow automations through user interfaces, which you can create using a number of
artifacts.
In a workflow automation,
tasks that are implemented as human services contain the user interfaces. Every human service
contains at least one coach in its flow. A coach creates a page in the user interface, which users
can see in a web browser. The human service can also include gateways and script tasks that affect
the flow of the user interfaces or change the variables that are passed into a coach.
Coaches can contain one or more views, which are reusable UI elements. Views can be
composite-style, which are simple views, or widget-style, which are more complex custom views. For
more information, see Views.

When you develop workflow automations, you use the designer to create coaches and views for client-side human services . When the human service is running, users see and interact with the coaches and views that you built in a web browser.
