Can I use create to replace establish?

Sure.

Dear roger,
thank you very much.

"One or more goals and questions have been created/established and organized in order to reach the selected metric."

I say no.

create is not the same as establish.

create is to make something. Are these goals and questions new?

establish may indicate that old policies have been selected, identified, or listed in order to reach the metric.

JMHO

I agree with Punky.

One formulates questions. One establishes goals.

Are you saying that your questions, and the goals that you set, had never existed before you 'created' them?

What the hell is a selected metric? That's jargon I'm not familiar with.

A metric refers to a measurement, such as, for example, a measurement of progress.

So an adjective is being used to signify a value (noun) for which the word already exists.

It's progress, Jim, but not as we know it.
