Process Automation Services -Workflow

Mechanism to model a business

process.

A network of activities performed

by a user or the system.

Flow of content and information

from activity to activity.

Logic that governs the sequence ofactivities.

Architected for WfMC compliance

Processes and activities are reusable

Workflow definition and runtime are

separate, improving performance and

efficiency

Architecture employs reference model

rather than duplication, easingadministration

Fully distributed model
