What Is a Chief of Staff?
Understanding—and Elevating—the Chief of Staff Role
“Is a Chief of Staff just a glorified assistant?”
It’s one of the questions we hear most often about the Chief of Staff (COS) position, and it’s an understandable one.
The Chief of Staff role has become increasingly common in the business world, but it remains broadly defined. Search for “Chief of Staff” on any major job board and you’ll find positions spanning everything from Executive Assistant/Chief of Staff to Chief Strategy Officer/Chief of Staff. The responsibilities can be just as varied.
But as the role has matured, the more important question is no longer simply, “What is a Chief of Staff?”
It’s: What should a Chief of Staff actually be spending their time doing? That distinction matters. Because even when an organization hires the right person and gives them the right title, a Chief of Staff can quickly become consumed by administrative work, coordination, information chasing, meeting logistics, and other responsibilities that keep them from operating at the strategic level the executive intended.
Understanding the Chief of Staff role is the first step. Designing the role—and the executive office around it—so the Chief of Staff can perform at the right level is the next.
What Is a Chief of Staff?
Here’s a useful definition:
Chief of Staff:a professional who serves as a project manager, people manager, and strategic advisor to a leader, allowing that leader to focus on their organization’s highest-level business priorities.
At its best, the Chief of Staff role creates leverage for an executive. The COS helps determine what requires the leader’s attention, what can be delegated, what needs to move across the organization, and what information the executive needs in order to make better decisions. The role can generally be understood through three core responsibilities:
Project Management
A strong Chief of Staff takes lower-priority work off the leader’s plate and ensures it gets to the right place. Sometimes that means delegating it to another person; sometimes it means owning the initiative directly. The Chief of Staff also guards against unnecessary work reaching the executive in the first place. For work that does need to move forward, the COS creates accountability across priorities, people, and timelines. They connect decisions to execution and help ensure important initiatives don't stall once the executive leaves the room. This is more than task management. At the appropriate level, a Chief of Staff is managing outcomes.
People Management
A Chief of Staff often serves as the “eyes and ears” of a leader. Executives naturally have gaps between themselves, their senior leadership team, and the broader organization. A strong COS operates across those gaps. By staying close to what is happening among departments, teams, and individuals, the Chief of Staff can identify friction, surface important information, facilitate communication, and help the executive understand what is happening beyond the information that reaches them directly. The COS may also help translate an executive's priorities back into the organization—making sure people understand not only what has been decided, but what needs to happen next. This makes the Chief of Staff an important connective layer between leadership and execution.
Strategic Advisory
A Chief of Staff is an active participant in much of what their leader does. As an extension of the executive, the COS develops context across the organization and uses that context to offer perspective, challenge assumptions, anticipate issues, and contribute to strategic conversations. They may prepare an executive for an important decision, identify competing priorities, synthesize information from across the organization, or simply serve as the trusted sounding board who can ask the question no one else in the room will. As a confidante and advisor, the Chief of Staff holds an important seat at the table. And ideally, this is where an experienced Chief of Staff increasingly spends their time.
The Chief of Staff Responsibility Spectrum
Not every Chief of Staff role looks the same. Depending on the executive, organization, and seniority of the person in the position, the role may fall somewhere along a spectrum from administrative and tactical support to strategic advisory and organizational leadership. A junior Special Assistant, for example, may spend more time toward the administrative end of that spectrum. A senior Chief of Staff should spend the majority of their time much closer to the strategic and advisory end.
That does not mean a Chief of Staff will never perform an administrative task. In a high-trust role supporting a senior executive, almost anything may occasionally need to get done. The important question is not whether a Chief of Staff ever does administrative work. It is how much of their capacity that work consumes.
If your Chief of Staff is consistently spending significant portions of the week scheduling meetings, tracking down updates, formatting information, manually maintaining follow-up lists, coordinating routine workflows, or moving information between systems and people, you may not have a Chief of Staff problem. You may have an executive office infrastructure problem.
Your Chief of Staff Shouldn't Be the Process
This is an important distinction for organizations that already understand the value of the Chief of Staff role. A highly capable person can compensate for a poorly designed executive office for a surprisingly long time. They remember who owes the executive an answer. They manually follow up after meetings. They know where every document lives. They reconstruct context from email and Slack. They maintain the executive's priorities in their head. They become the bridge between disconnected systems, processes, and people. From the outside, this can look like exceptional performance. But it creates a problem: the Chief of Staff becomes the operating system.
The more administrative and coordination work that depends on the COS personally remembering, chasing, organizing, and transferring information, the less capacity they have for the work only they can do. A well-designed executive office uses clear processes and appropriate technology to carry more of that operational load. Routine information should have a reliable path to the executive. Decisions should generate clear ownership and follow-up. Priorities should be visible. Recurring workflows should not have to be rebuilt every week. Information should be captured and organized in ways that make it useful rather than requiring a Chief of Staff to constantly hunt for it.
Technology—including increasingly capable AI tools—can support many of these workflows. But technology alone isn't the answer. Automating a poorly designed process simply gives you a faster poorly designed process.
The goal is to intentionally determine what should be handled by a person, what should be handled by a process, and what can be enabled or automated by technology. That creates room for a Chief of Staff to operate where their judgment, organizational context, relationships, and strategic thinking provide the greatest value.
How to Elevate an Existing Chief of Staff
If you already have a Chief of Staff, look beyond their job description and examine how they actually spend their week.
How much of their time is spent:
preparing and participating in strategic discussions?
moving critical initiatives forward?
identifying risks and organizational friction?
synthesizing information for better executive decisions?
aligning leaders and teams around priorities?
And how much is spent:
chasing updates?
scheduling and coordinating?
manually capturing and distributing information?
maintaining trackers?
following up on routine action items?
transferring information between tools, meetings, and people?
The second category won't disappear completely. Nor should it. But if it dominates the role, there is an opportunity to redesign the processes around the Chief of Staff rather than simply asking the person to become more efficient. Often, elevating a Chief of Staff doesn't require changing the person at all. It requires changing the system in which they operate.
Hiring a New Chief of Staff? Start the Role at the Right Level
This same principle is especially important when hiring a Chief of Staff. Organizations sometimes make the mistake of hiring an exceptional strategic operator into an executive office that has no operating infrastructure—and then expecting that person to build the infrastructure while simultaneously performing the strategic role.
The result is predictable: urgent administrative needs win. The new Chief of Staff becomes the default owner of everything that does not have another obvious owner. Over time, responsibilities accumulate and the strategic role envisioned during the hiring process looks very different from the job being performed six months later.
Before a new Chief of Staff starts, consider the environment you're asking them to enter.
Are the executive's priorities clear? Are meeting and decision-making rhythms established? Is there a reliable method for capturing commitments and following through on them? Are responsibilities between the Chief of Staff, Executive Assistant, executive, and leadership team clearly delineated? Are the right systems and tools in place to support the work?
The stronger that foundation is, the faster a new Chief of Staff can move beyond organizing the executive's world and begin creating leverage within it.
A Chief of Staff Is More Than a “Glorified Assistant”
So, is a Chief of Staff just a glorified assistant? No.
But organizations can unintentionally turn the role into one when administrative and operational responsibilities consume too much of the Chief of Staff's capacity. A true Chief of Staff is a highly valuable right hand to company leadership: part project leader, part organizational connector, and part strategic advisor.
The opportunity today is not simply to understand the Chief of Staff role more clearly. It is to design the executive office so the Chief of Staff can actually perform that role. That means defining responsibilities appropriately, putting repeatable processes around the executive, using technology intelligently, and reserving your Chief of Staff's time and attention for work that benefits from their judgment, context, relationships, and strategic perspective.
The best question may no longer be, “Do I need a Chief of Staff? ”
It may be: “Have we built an executive office that allows our Chief of Staff to operate at their highest level?”
It is critical to delineate the roles, responsibilities, and experience of a Chief of Staff within your organization—but the work shouldn't stop with the job description. Prime Executive Office helps leaders think more broadly about how their executive office operates: the people, processes, and technology surrounding the executive and enabling their highest-value work.
