operationalize

To make operational.

I have a lot of sexual fantasies that I'm never going to operationalize. I enjoy them just as fantasies.

To define (a concept) in such a way that it can be practically measured.

To operationalize a concept is to identify those variables in terms of which the phenomenon represented by the concept can be accurately observed.

Vision seems ‘childishly simple’ to us but proves to be fiendishly hard to operationalise, precisely because we are so good at it.
