A Brief History of eTOM
What is a workflow?
It is an automation of a complete or partial process dringwhich documents, information and/or tasks are passed from
one participant to another.
But...
Without intelligent interfaces to NEs and OSS, workflow aloneis inadequate for automating communications processes.
Business process
It is a logical sequence of tasks that accomplishes a function
such as:
Validating an order
Designing a new circuit
