"We need somebody with GRAVITAS," I am often told by conference organizers and others who are interested in hosting a business leader from my company as speaker. But they never really define what they mean by "gravitas," and so they make the word useless as a clear expectation of the kind of leader they really want. Typically they use the word to mean that they want someone high-level and with a fancy title to get the audience interested in attending.
Recently I found myself reading a biography of the old Roman emperor and leader Augustus and, there it was. A definition of "gravitas," which was covered as one of several qualities of good Roman leaders:
Gravitas: A serious (sometimes oversolemn) approach to the challenges of life.
So, if you use the word gravitas to describe a leader you want to engage, you better know what precise kind of challenge you know this leader to have approached in an "over solemn" way (which I suppose means in a very, very, very serious and focused way). I don't think the challenge has to be just about life, but can be about business and the challenges of purposeful leadership, innovation and achieving objectives.
You also better know exactly why an audience would be interested in learning about the leader's approach to the challenge at hand, and how the approach can or should be applied in a variety of different situations (different audiences have different needs).
And lastly, I would hope you can be ready to challenge this leader with new assumptions and new ways of thinking just to make things even more interesting.
