The Case for a Chief of Staff

The article “The Case for a Chief of Staff” appeared in this month’s issue of Harvard Business Review “The Agile Executive: How to balance efficiency and innovation (even in tough times like these)”.

This article outlines that many chief executives need a Chief of Staff (CoS). Someone who goes beyond the executive assistant role to help the office function smoothly. And that the right Chief of Staff can be an important source of assistance to leaders who are pushing their organizations and themselves to better performance. We could not agree more.

Therefore, please find below this article’s highlights.

When new CEOs with a change mandate take over a company, they typically invest time in reshaping its strategy and determining the kind of culture needed to succeed. Those choices guide other decisions, including who their senior managers will be and how the leaders will allocate their time.

   Key factors that will help determine effectiveness

Most new CEOs pay little attention to a key factor that will help determine their effectiveness: the administrative system that guides day-to-day operations in their offices. This system ensures that leaders make the most of their limited time. That information arrives at the right point in their decision-making process. And that follow-up happens without them having to check. Many new CEOs default to the system they’ve inherited. Even if it is poorly suited to their style or to the operational changes they must make. Often there’s a better way to handle the information flow necessary for a CEO to succeed— and very often a Chief of Staff (CoS) can play an essential role.

   The role and responsibilities of a Chief of Staff (CoS)

Although each leader should tailor the position to his or her own needs, the Chief of Staff should handle several principal duties. All focused on making time, information, and decision processes more effective. Patrick Aylward, a vice president and CoS at Horizon Blue Cross Blue Shield of New Jersey, breaks the job down into five roles: 

  • serving as an air traffic controller for the leader and the senior team.
  • Integrating work streams that would otherwise remain siloed.
  • Communicating to link the leadership team and the broader organization.
  • Acting as an honest broker and truth-teller when the leader needs a wide-ranging view without turf considerations.
  • Serving as a confidant without an organizational agenda.

Aylward points out that “while a CEO’s other direct reports typically emphasize their own areas, a good CoS can consider the needs of the whole enterprise.”

The most sophisticated Chiefs of Staff also assist CEOs in thinking through and setting policies – and making sure they are implemented. They anticipate problems and are especially sensitive to issues that require diplomacy. As well as functioning as extra eyes and ears by pointing out political potholes their bosses may not recognize (especially if the bosses are new to the company). Importantly, a Chief of Staff acts with the implicit imprimatur of the CEO – something that calls for humility, maturity, and situational sensitivity.

The CoS role is decidedly different from that of the leader’s executive assistant (EA). Unlike an EA, a Chief of Staff works autonomously and does not handle routine correspondence or manage the leader’s day-to-day schedule. The highest-level CoS should be a full-fledged member of the senior leadership team. Albeit without the rank or compensation of a C-suite officer.

   Sharp gains in productivity and impact

Regardless of specific responsibilities, a Chief of Staff can help a leader achieve sharp gains in productivity and impact. Take an executive I’ll call Joe, who was promoted from head of sales and marketing to president of a midsize company that had just been acquired. Meaning that Joe was now reporting to a chairman and CEO at a distant headquarters, adding political complexity to the job. A few months in, he was struggling. “I wasn’t myself,” he recalls. “I was a step slower. I was working longer hours than I ever had but not getting as much done and not spending time on what mattered most.”

A CoS’ primary duties make time, information, and decision-making more effective.

At some large companies, executives reporting to the CEO also choose to have a Chief of Staff. One CHRO has employed five over the past 10 years while working at two Fortune 100 companies. “The most visible benefit for me has been time,” he says. “I’ve picked up a third more time, and I’ve been able to get more done. Just as important is that my Chiefs of Staff created a system so that I can stay focused on my CEO and board and still make sure that the day-to-day things don’t fall by the wayside.” This executive treats the CoS role as a rotational one lasting two to four years. It’s a coveted assignment because it’s typically a springboard to a bigger job: Three of his prior Chiefs of Staff went on to become the chief learning officer, the head of talent acquisition/planning and leadership development, and a senior manager in the compensation department.

   The origin of the Chief of Staff role

The Chief of S role originated in the military and government. And it dates back centuries. Cicero, the Roman politician and orator, used a slave named Tiro. According to Cicero’s biographer Zach Bankston, Tiro served as a secretary, a financial overseer, and a political strategist. Andrew Roberts’s Napoleon: A Life describes the vital role that Louis-Alexandre Berthier played in assisting Napoleon at the height of his powers. The historians Ron Chernow and Joseph Ellis have described the CoS–like role that Alexander Hamilton played for George Washington. These people aren’t to be confused with the personal secretaries or aides-de-camp that each leader also had. Rather, they were close advisers. Theyhandled the most delicate strategic matters and became trusted confidants.

Lately, the Chief of Staff position has become more common in corporations. According to Tyler Parris, the author of Chief of Staff: The Strategic Partner Who Will Revolutionize Your Organization, 68,000 people held the CoS title in 2015 in nonmilitary, nongovernment organizations in the United States – mostly large companies. Parris found that half the companies use a rotational model. In which high potentials are tapped to spend a set period (typically two years) in the role and then move to a line job. At companies that don’t use a rotational model, people often remain CoS for five years or more.

   Two other key success factors

Two other factors will determine whether incorporating a Chief of Staff into the chief executive’s office will improve things.

First, is the leader willing to make changes to his or her routine once the Chief of Staff is aboard? If the CEO is used to being his or her own Chief of Staff and continues to act that way after hiring one, not even the best aide will succeed.

Second, will the two of them have a relationship that allows the effective giving and receiving of feedback? From the very outset, the CEO should make a deal with the new Chief of Staff: If she hones her ability to give feedback, the CEO will be open to it and listen carefully. The relationship that results will improve performance and satisfaction for both leader and subordinate.


Everyone requires help to achieve their highest potential. And to sustain the effort it takes to lead a complex organization. The right Chief of Staff can be an important source of assistance to leaders pushing their organizations and themselves to ever better performance.
