Holy cow, I wrote a book!
Here are a few citations for the word
A lot of work lies ahead to
operationalize this plan.
Provide security guidance and tools to help operationalize
security for enterprise environments.
I thought it meant "carry out" or "put into effect",
and then I saw this sentence:
Operationalize the demo (get computers configured,
install software, verify network access).
Now I'm not sure any more.
