I'm trying to reference a business process in which a document has to be approved by several different people before it is finalized. I want to be able to say things like:
We've modified the workflow to include an additional step.
The workflow currently requires approval by three people.
Merriam-Webster Unabridged does not have an entry for "workflow", but I see many people using it anyway. Is it a word or not? If so, is there a good dictionary definition of it?
