Have you noticed the high level of activity in switching out CEOs and other executive team and board members? It’s happening in large and small lmanufacturing and service companiess. This morning I reviewed one business  publication and saw at least 20 announcements about new executives that were expected to bring a higher level of performance than their predecessors. I wonder if the people coming in are aware of the barriers that prevented the last guy (or gal) from achieving the desired of performance? If the real barriers to excellence were understood, wouldn’t the prior leaders have addressed and overcome them? It seems a logical question to ask because they had everything to gain by doing so. Executives are replaced when their barriers to improvement aren’t understood. With a higher level of awareness of management’s barriers to change comes higher performance and greater job security for executives responsible for delivering it.
