He couldnt return any more than Bill can because the IBM he knew was dead and the fire that drove him to build it was gone. Over the years Ive watched founders go and return and while there are some successes (like Apple), there are far more failures. Lets explore the why of this.
But generally that success has more to do with the broad skill match of the employees in place at the time, the market, and the relationship with the customers. When a company is in trouble its generally because of multiple problems. The market has changed, customers have moved on and created relationships with other vendors, and the people who built the company have moved on as well.
Much like it would be if you had a car that was losing a racing series because it was no longer competitive, just replacing the driver or the tires wouldnt fix the problem alone. Bringing back a successful CEO isnt a fix for an ailing company.
They will step into a firm that is vastly more complex than the one they left, have executives that see him or her as more of a threat than a savior and be facing a market that looks similar but is in fact vastly different.
Expectations from the employees are that the founder will magically wave their hands and the company will recover. Granted, morale will come up initially but when the magic doesnt follow the disappointment and disenchantment can undo any advantage. Ask anyone who was around when Gateways founder returned.
An executive whos good at building companies has as his primary tools knowledge of the product, integrity, a desire to take care of those who take care of him, the ability to command loyalty, and not an insignificant amount of personal charisma.
A good turn around manager has to have, on top of these skills, the ability to set aside personal feelings and make decisions that will create a lot of initial enemies and place company needs ahead of personal relationships. Ive recently written on general process of turning a company around and it continues to amaze me that few realize that this process begins with perception.
An executive building a company needs a deep expertise in whatever it is the company does. This typically is a plus with a turnaround executive but more important is a broad set of business skills on motivating people, understanding business process, and separating out the BS.
The environments both operate in are different. The builder, during a time of success, operates in an environment of trust; employee loyalty is generally a given. The turnaround executive operates in an environment of distrust; loyalty has to be built and assured. I think of a good builder CEO as closer to a benevolent monarch with an edge, while a turnaround manager is more like a warlord. Both can do combat but the warlord lives in and for battle.
Conversely when a company needs a turnaround manager the benevolent monarch wont make the truly hard decisions necessary and if the warlord is successful they will either lose interest or drive the company into the ground. There is something to picking the right skill for the job.
Even though Carly was brought in as a turnaround executive she appeared to approach the problem much as a manager might who was building or sustaining a company. She was initially accepted much like a founder might be, as a breath of fresh air and a visionary. She presented well and was extremely articulate at promising hope and needed change.
However, she lacked operating skills, she didnt surround herself with people she could trust and didnt take care of the people she surrounded herself with. As a result, she was shot from inside, something that I dont think she ever did figure out (she blames the board in her book but that board was being fed by her people).
Mark Hurd, on the other hand, didnt trust anyone initially, brought in people loyal to him, held everyones feet to the fire, and focused on strong business fundamentals. Carly was a bit overly focused on her compensation and perks as well, but that is another story.
Ironically much of what was done to turn HP around was consistent with Fiorinas vision but she simply couldnt get the job done and almost got ousted early during a proxy fight that could have been avoided. One piece of additional information: it was the proxy fight that assured the HP merger with Compaq wasnt a train wreck because it became a forcing function for good merger process. This is something that wouldnt have existed if a strong merger plan hadnt been needed to win the proxy fight.
