More musings from Drupa, day nine.

We've broken the back of the show now, and the intense press conference schedule of the first week is behind us.

One of the fascinating things from my own point-of-view has been observing the CEOs of a variety of manufacturers in their not-so-natural habitat.

The differences truly are extraordinary, and it made me think about how this must affect the culture at their various organisations.

I've met with CEOs who are amusing and engaging, yet most certainly as tough as nails should the need arise.

I've also seen CEOs who clearly have their entire team in a state of perpetual terror, fearing the next cat-kicking incident.

I've seen CEOs who have a bag carrier for their bag carrier.

I've seen CEOs talking about some new product or other that really should be very interesting, but with the sort of delivery that makes Arnie's turn in The Terminator look lively.

I've seen CEOs who've made a brief flag-waving appearance; and others who'll be here for the whole show.

I've seen CEOs who've talked with genuine passion about their products, customers and companies.

And I've seen CEOs who think that inserting the word "passionate" in a sentence will make it so.

All in all it's fascinating. Yet again I am reminded about the excellent biography of the late, great Steve Jobs, and the contradictions within this hugely successful man. He was an inspiration and a nightmare rolled into one.

There's no one-size-fits all when it comes to the big boss, but I know which combination of qualities I'd prefer to be working for.
