Versatilist

A Versatilist is someone who can be a specialist for a particular discipline, while at the same time be able to change to another role with the same ease.

The term "versatilist" was first coined in an article from Gartner, where it states:

It is to the advantage of an organization to employ versatilists—because an enterprise will be able to easily redeploy this type of employee based on changes in business requirements or strategy.
