A recent Wall Street Journal report describes Ken Kutaragi as a "stumbling block" to Sony CEO Howard Stringer's success. The Wall Street Journal report by Roger Ehrenberg says that Kutaragi was known for his "reluctance" to keep lines of communication open with his bosses or other departments of the company - most notably, with the Sony Electronics Division.

This bit of news is relevant to all of you console war spectators since it is the Sony Electronics Division that provides the parts for Sony PlayStation products. Not a group you'd want to upset if you're banking on the PSP or the PS3. Ehrenberg notes:

In developing the PlayStation 3 console, the device's latest iteration, Mr. Kutaragi went over budget on development costs without informing Mr. Stringer, according to a person familiar with the situation. When Mr. Stringer urged Mr. Kutaragi to have dinner with the heads of the electronics division, he did so just once a year, this person said. A spokeswoman for Mr. Kutaragi declined to comment.

I don't care how legendary or historically successful a manager might be - if they are unable or unwilling to adapt to the culture, the vision you, as leader, have clearly communicated, they have to go. But not two years later, after the corrosive effect of doing things "their way" has already sunk in. Having a senior manager blame other groups for his group's woes? Raising concerns of investors, suppliers and customers alike? Unacceptable everywhere and at any time in any culture.
