If the board were to select one of these two to head the company, the key difference between the two is: while Murthy will make the company to meet ground zero at the speed of light, Diane would do it at the speed of sound.
Diane is nothing but a cheerleader and that is what she did in quarterly updates when company server program was not doing well, there simply was no problem every thing in her eyes was just peachy, refused to admit reality.
Murthy struggled to clean up the roadmap and has achieved nothing over years other than internal factions and bickering.
Hope the board has more sense than choosing one of these two
