Sony had its own approach to this(citing Yoshide Nakamura):
Our company management felt that to prepare the company for the digital network era of the 21 century, it was important to have the most appropriate organizational structure in place. That was the core reason why we created our new structure. Sony is a large company now. Our worldwide consolidated sales are over $56 billion, with 170,000 employees, but in spirit we always try to be small venture company. We want to maintain this, So when Mr.Nabuyuki Idei became president in April 1995, he gave us two slogans: "Regeneration" and "Digital Dream Kids." Thats the spirit of being small and going back to when we started Sony in 1946. So we want to make Sony smaller. Instead of having this huge corporation, he wants to organize Sony into four divisional companies so that a small venture capital spirit can be brought into management
I wonder which large companies have held out against this type of decay through the decades and how they managed it.
