How not to lose the top job.

If you're on the way to becoming CEO, take care. Many anointed successors find their path to the corner office unexpectedly blocked. The obstacle is usually a mismanaged relationship with any of six kinds of stakeholders: the current chief executive, the successor's peers, his or her direct reports, customers, analysts and shareholders, and the board of directors. Succession isn't an entirely rational process, explains veteran executive coach Goldsmith. Personal issues, egos, and emotions influence succession decisions just as much as business logic. Look at what happened in 1978 to Lee Iacocca, considered by many the obvious candidate to become head of Ford. Iacocca didn't just fail to get the job--he was fired. In explaining why, Henry Ford II famously remarked, "Sometimes you just don't like somebody." To secure their promotion, prospective heirs must strengthen relationships with the stakeholders whose commitment they'll need to succeed as CEO. That involves striking a delicate balance in a number of areas. For instance, candidates must project readiness to lead while supporting the current CEO, showing respect for peers, and demonstrating that they can make tough decisions without alienating their reports. It's also critical for them to determine if they've made past missteps that call for a change in personal style or relationship-building approach. The current CEO can provide invaluable guidance on areas ripe for improvement, as well as many other issues, such as which customers aspiring successors need to get to know or what the concerns of individual board members might be. Building better relationships with stakeholders takes time and effort, and treading so carefully may be wearying. But executives who do it before they become CEO stand a much better chance of making it across the finish line and in the end will become much more effective leaders.
