I've seen that before in person. Three months ago we had a CEO, COO, and CIO. The CIO wanted to be CEO. The CEO didn't like him (a lot of people didn't like him) so the CIO left. The COO was supposed to take over but he waslooking at retirement, not taking over for the 70 year old CEO. On top of that the COO and the CEO were very different people.
After the CIO left, the IT sector imploded into a morass of backstabbing that reminded me of Lord of the Flies. The CEO thought he could fix it better than the COO (who was the former CIO). Needless to say he made things worse. The CEO and COO had a falling out, the COO "retired" leaving the CEO to try and fix the mess he created. The pressure cracked him, he did a lot of crazy things, and the board kicked him out.
Not we don't have a CEO, we have a CAO (chief admin officer) who took over everything, and we have someone who was forced to become the CIO despite the fact that he said he didn't want it and wants to leave.
Bad decisions at the top can quickly spin out of control. I figure it will be five years before we have a long term CEO, COO and CIO again. In the meantime I'm hiding under my desk, sharpening sticks, and smearing black paint on my face.
