Well, clearly a huge difference. Under Platt HP had good consistent growth, and we enjoyed record profit sharing and bonuses. Fiorina joined and managed to cut the company's value by 50% in three years. Hurd joined and the company's value went right back up. The difference in execution and competence was startling.
IDK, but the real story must surely be the board of directors (which hires, fires and sets the salary for the CEO). How can a board be so incompetent that it negotiates a severance package whereby Fiorina receives $42 Million to leave after loosing half of the company's value.
When you look at the following graph, keep in mind the Great Recession in 2008.

There's this claim that CEO compensation doesn't correlate well performance. I could see your Carly Fiorina and raise you Steve Jobs or Jack Welch or any other number of anecdotes. What's the real statistical correlation in the S&P 500?
Marissa Mayer got a nice compensation package because she did well by Yahoo investors: she managed to trick Verizon into paying real money to buy the hulking wreck of Yahoo.
If you start out thinking that Yahoo could ever possibly have been saved in any alternate universe, you can get all-kinds of angry or disappointed in Mayer's performance. But if you see Yahoo for what it was, you realize she really did arrange the best possible deal that Yahoo shareholders could have hoped for.
