Success is not about the revenue generated, as we've seen small companies be far more successful on many dimensions than some of the largest publically traded companies. Nor is success (at least the way I measure it) based on the size of the bank account of the CEO. To me, success is about how employees feel about an organization. Do they feel a sense of "ownership" – is it something they have been entrusted with to care for, and do they take their duties seriously, acting with passion and dedication? This creates sense of loyalty and ownership of any company initiative creates success.
