WHAT IS IT, exactly, that people are really afraid of when they say they don't like change? There is the discomfort of being confused or the extra work or stress the change may require. For many people, changing course is also a sign of weakness, tantamount to admitting that you don't know what you are doing. This strikes me as particularly bizarre--personally, I think the person who can't change his or her mind is dangerous. Steve Jobs was known for changing his mind instantly in the light of new facts, and I don't know anyone who thought he was weak. Managers often see change as a threat to their existing business model--and, of course, it is. In the course of my life, the computer industry has moved from mainframes to minicomputers to workstations to desktop computers and now to iPads. Each machine had a sales, marketing, and engineering organization built around it, and thus the shift from one to the next required radical changes to the organization. In Silicon Valley, I have seen the sales forces of many computer manufacturers fight to maintain the status quo, even as their resistance to change caused their market share to be gobbled up by rivals--a short-term view that sank many companies. One good example is Silicon Graphics, whose sales force was so accustomed to selling large, expensive machines that they fiercely resisted the transition to more economical models. Silicon Graphics still exists, but I rarely hear about them anymore.
