One of the things I often do when I visit a client's office is to size up the office decor and environment. This usually tells me something about the culture and perhaps even the values of the organization.
In a similar vein, it is instructive to see how the desk of the CEO of an organization look like, as it will give you an idea of the person. In this article from the Business Insider, we take a peek at the desks of some very successful people in the corporate world.
I can attest to this because, I have personally come across the desk of the CEO of a certain local company which was a real mess (imagine piles of books, pieces of notes, scrolls of engineering drawings and who knows what else pile a foot high on the desk in one huge clutter). According to one of his staff, it was an 'organized mess' as the CEO was able to find whatever he wanted whenever he wanted from the pile on his desk, provided no one else disturbed the clutter.
Well, to cut a long story short, a few months later, the local company got into a big legal mess when the structure they were building collapsed and they got fined by the regulators. It was only by good fortune that no one was hurt.
So in essence the desk, or whatever the workspace that the CEO uses can tell a story about the organization's culture and values.
