Seven Roles of the COO

Not one Chief Operating Officer (COO) is alike. Well, that’s obvious because not one human is alike. All COO roles are different based on the motives behind the job. Below you will learn about the seven different roles of the COO.

Second in Command: The Misunderstood Role of the Chief Operating Officer

If the COO role is defined primarily in relation to the CEO, and no two CEOs are exactly alike, does that mean the job simply defies definition? Not quite. What became clear in the course of our research is that the differences among COO roles arise from the different motives behind creating the position in the first place. It turns out there are seven basic reasons why companies decide to hire a COO, and these yield seven roles that COOs can play vis-à-vis their CEOs. Readers will recognize that the seven reasons are not mutually exclusive, though in this initial presentation we treat them as such.

The Executor

One role of a COO is to lead the execution of strategies developed by the top management team. It’s simply a concession to the complexity and scope of the CEO’s job today, with its numerous external commitments. Managing large, often global, enterprises sometimes require two sets of hands; in such cases, the COO typically takes responsibility for delivering results on a day-to-day, quarter-to-quarter basis.

This is why the COO position is nearly ubiquitous in businesses that are operationally intensive, like the airline and automotive industries, as well as in organizations that operate in hypercompetitive and dynamic marketplaces like high-tech firms. At Seagate Technology, for example, CEO Bill Watkins relies on COO David Wickersham to keep the business performing at its peak. It’s not that Watkins lacks an execution mindset himself; in fact, he ascended to his post after excelling as COO to the previous CEO, Stephen Luczo. But the demands of managing an $8 billion vertically integrated disk-drive business are substantial. By bringing in a COO to lead and oversee the day-to-day operations, Seagate allows Watkins to focus on the strategic, longer-term challenges the company will face. CEO Watkins is clearly oriented with his “head up” to understand success in the future, whereas COO Wickersham has his “head down,” focused on the operational details necessary for success today.

The Change Agent

Just as Microsoft did when it hired Kevin Turner, some companies name a COO to lead a specific strategic imperative, such as a turnaround, a major organizational change, or a planned rapid expansion. While the mandate is not as broad as the general execution of strategy, the magnitude of the challenge demands that the change-agent COO have a degree of unquestioned authority similar to that of an executor COO. This was, in fact, what led to Ray Lane’s arrival at Oracle. Larry Ellison hired Lane from consultancy Booz Allen Hamilton and tasked him with turning around the deeply troubled sales and marketing organizations. His efforts ultimately contributed to a 10-fold increase in sales, from $1 billion to more than $10 billion, and a threefold increase in net profits. Similarly, AirTran CEO Joe Leonard recruited COO Robert Fornaro to lead a dramatic turnaround. The company, in Leonard’s words, was “running on fumes” and needed dramatic efforts to stave off bankruptcy.

The Mentor

Some companies bring a COO on board to mentor a young or inexperienced CEO (often a founder). A rapidly growing entrepreneurial venture might seek an industry veteran with seasoning, wisdom, and a rich network who can develop both the CEO and the emerging business. One could logically hypothesize that as the CEO develops, this COO role might either disappear or be heavily restructured.

By many accounts, this was what prompted the young Michael Dell to hire Mort Topfer in 1994. Dell was growing at a pace that threatened to get ahead of its founder’s managerial experience. Michael Dell was self-aware enough to acknowledge that he needed some seasoned executives around, both to capitalize on the market opportunity and to accelerate his own development as a leader. Topfer was in his mid-fifties at the time and was completing a successful career at Motorola. He clearly had no aspirations of becoming the chief executive officer at Dell—he was there to help the 29-year-old Michael. We’ve seen very similar arrangements at Netscape, where James Barksdale has served as mentor to cofounder Marc Andreessen, and at Google, where Eric Schmidt was recruited to support the cofounders, Larry Page and Sergey Brin.

The Other Half

A company may bring in a COO not as a mentor, but as a foil, to complement the CEO’s experience, style, knowledge base, or penchants. Observers have viewed the relationships between Bill Gates and two of his previous COOs, Jon Shirley and Michael Hallman, in this light. Jon Shirley, according to one observer, provided a “calm, self-effacing balance” to Gates’s brilliant and often intimidating affect. In such cases, the COO role is usually not meant to lead to a higher position—but sometimes it is. When Ken Freeman, now a managing director of Kohlberg Kravis Roberts, was CEO at Corning spin-off Quest Diagnostics, he deliberately sought an heir with a different collection of skills than his. He ultimately hired Surya Mohapatra just when Quest was closing a deal to acquire another large testing business. “I thought, in a company that was going from $1.5 billion in revenues to $3.2 billion,” he explained to us, “it would be helpful to have somebody around that had strong health care experience—especially given that I had grown up in the glass business!”

The Partner

Sometimes, the CEO is simply the kind of person who works best with a partner. This can lead to what’s been called a “two in a box” model and is similar to what authors David Heenan and Warren Bennis have termed “co-leadership.” Indeed, Heenan and Bennis contend that more companies should create and cultivate co-leadership arrangements. But it’s probably true that, just as there are doubles specialists in tennis, only some executives are more effective when paired. In any case, Michael Dell and Kevin Rollins, whom Dell introduced as COO in 1996, seem to operate in this mode. Dell, as chairman, and Rollins, now as CEO, are committed to leading the firm together, even choosing to “co-office” in adjoining work spaces separated by only a glass partition.

The Heir Apparent

In many cases, the primary reason to establish a COO position is to groom—or test—a company’s CEO-elect. The broad purview of the job allows an heir apparent to learn the whole company: its business, environment, and people. Recent examples of firms using the COO position to develop the successor to the CEO include Continental Airlines, where CEO Gordon Bethune (who himself originally joined the airline as COO) recently passed the torch to his COO, Larry Kellner. Similarly, in the time after Rex Tillerson was appointed to the number two position at Exxon, observers noted that he was increasingly exposed to the public—a deliberate effort to facilitate his succession to CEO Lee Raymond. And when Norfolk Southern appointed Charles Moorman as second in command, the transportation company touted him as the heir, continuing its avowed “practice of picking an executive young enough to lead the company for at least a decade.”

Certainly, being identified as a likely heir does not represent anything approaching a guarantee. On the one hand, an otherwise valuable senior executive may leave if the top job ultimately goes to someone else—or isn’t offered soon enough. On the other hand, the COO’s performance can indicate that the heir title was inappropriately or prematurely bestowed. In the past few years, we’ve seen several prominent COOs who seemed to be on the glide path to the CEO’s office instead leave their companies; they include John Brock (Cadbury Schweppes), Mike Zafirovski (Motorola), John Walter (AT&T), and Robert Willumstad (Citigroup). Regardless of whether each left because he was passed over for the CEO position, because the timing was not as advertised, or because he found greener pastures, the succession plan unraveled.

The MVP

Finally, some companies offer the job of COO as a promotion to an executive considered too valuable to lose, particularly to a competitor. This appears to have been the case at News Corporation’s Fox Entertainment Group subsidiary. It recently announced that its president and COO, Peter Chernin, had signed a new employment agreement preventing a rumored move to rival Disney. Similarly, when McDonald’s restructured the roles of its U.S. and Europe presidents during the summer of 2004, that was interpreted by analysts as an effort to ward off poachers. With this strategy, an organization may try to hedge its bets by stopping short of identifying a specific heir or setting a timetable for leadership succession, in an effort to keep its high-potential executives intrigued about what the future might hold for them, should they stay on board.
