What Is the Role of a Chief of Staff?

A Chief of Staff is one of the most influential strategic support roles within a modern organisation. Yet for many leaders exploring the concept, there is still a lack of clarity around where the role begins and ends, and how it differs from more traditional forms of executive support.

In practice, the scope of a Chief of Staff can vary significantly depending on the size of the organisation, the needs of the leadership team, and the stage of growth. In some cases, the role sits close to operational coordination, while in others it becomes deeply embedded in strategic planning and decision-making.

So what does a Chief of Staff actually do on a day-to-day basis, and how do they operate within a leadership team?

To understand the role properly, it helps to look at how it functions across both strategy and execution, and the ways it interacts with leadership priorities, internal teams, and organisational rhythm.

While every organisation defines the role differently, the most effective Chiefs of Staff share a common purpose: enabling leaders to operate at their highest level while driving greater alignment, accountability, and momentum across the organisation.

What Does a Chief of Staff Do?

At its core, a Chief of Staff helps ensure that a leader’s priorities become organisational realities. Acting as a strategic extension of a CEO, Founder, or senior executive, they bridge the gap between decision-making and execution, ensuring key initiatives maintain momentum, stakeholders remain aligned, and critical objectives do not lose focus.

Rather than managing a single function, a Chief of Staff typically operates across the organisation, providing visibility, coordination, and accountability wherever it is needed most. While the specifics vary from business to business, the role is often built around three core pillars:

The Three Pillars of the Role

1. Strategic Advisor: A Chief of Staff helps leaders focus on what matters most. They provide context for decision-making, identify competing priorities, challenge assumptions where necessary, and ensure executive attention remains directed towards the initiatives with the greatest strategic value.

2. Operational Architect: Behind every high-performing leadership team is a framework that keeps people, processes, and information aligned. A Chief of Staff helps streamline communication, improve cross-functional collaboration, establish accountability, and remove operational bottlenecks that can slow progress.

3. Proxy & Facilitator: A Chief of Staff often acts on behalf of the executive, representing their priorities in meetings, coordinating stakeholders, leading special projects, and ensuring decisions are communicated and implemented effectively. By extending the reach of leadership, they help organisations move faster without sacrificing alignment.

Core Chief of Staff Responsibilities

No two Chief of Staff roles look exactly the same. In some organisations, they act as a strategic partner to the CEO; in others, they operate as the connective tissue between leadership teams, departments, and major business initiatives.

Typical Chief of Staff responsibilities may include:

• Driving high-priority strategic initiatives and cross-functional projects, ensuring key objectives remain on track and stakeholders stay aligned.

• Managing executive communications and the leadership ecosystem, acting as a central point of coordination between senior leaders, department heads, board members, and key external stakeholders.

• Overseeing board meeting preparation and executive reporting, including agendas, briefing materials, action tracking, and strategic updates.

• Acting as a trusted sounding board for sensitive decisions, providing perspective, challenge, and discretion when navigating complex business matters.

• Identifying and resolving organisational bottlenecks, removing friction before issues escalate and helping maintain operational momentum across the business.

At the highest level, a Chief of Staff creates clarity, facilitating execution, and ensures leadership attention remains focused on the areas where it can have the greatest impact.

How to Become a Chief of Staff

For professionals wondering how to become a Chief of Staff, there is rarely a single path into the role. Chiefs of Staff come from a diverse range of professional backgrounds, including management consulting, business operations, strategy, project management, finance, product management and senior executive support.

Formal qualifications can be valuable, particularly degrees in business-related disciplines or postgraduate qualifications such as an MBA. However, experience is often the defining factor. The role requires a broad understanding of how organisations operate, the ability to navigate complexity, and the judgement to support high-stakes decision-making at the highest level.

Rather than following a prescribed career path, successful Chiefs of Staff tend to have one thing in common: they have earned the trust of senior leaders by demonstrating sound judgement, commercial awareness and the ability to drive outcomes across multiple areas of the business.

Essential Skills for a Chief of Staff

The most effective Chiefs of Staff combine strategic thinking, operational excellence and exceptional interpersonal skills. They are trusted partners to senior leaders, capable of moving between high-level strategy and detailed execution while maintaining alignment across the organisation.

Key qualities often include:

1. Strategic thinking and problem-solving – the ability to understand complex business challenges, identify opportunities, provide perspective and help leaders make informed decisions.
2. Exceptional project and programme management skills – the ability to coordinate multiple priorities, drive cross-functional initiatives and ensure strategic objectives translate into measurable outcomes.
3. Commercial awareness – a strong understanding of business goals, organisational dynamics and the wider factors influencing decision-making.
4. High emotional intelligence (EQ) – the ability to build trust, read situations effectively and develop strong relationships with executives, stakeholders and teams across the organisation.
5. Influencing without formal authority – the ability to align people around shared priorities, create accountability and maintain momentum across different functions.
6. Outstanding communication skills – the ability to distill complex information, prepare executive briefings and ensure important decisions are clearly understood throughout the organisation.
7. Discretion and sound judgement – the ability to handle confidential information, navigate sensitive situations and act as a trusted advisor to senior leadership.
8. Adaptability and resilience – the ability to operate effectively in fast-moving environments where priorities evolve quickly.

Transitioning into a Chief of Staff Role

Although there is no single route into the profession, many professionals naturally evolve into Chief of Staff positions as their responsibilities become increasingly strategic.

Individuals with backgrounds in management consulting, business operations, project management and strategy often move into Chief of Staff roles because they have experience leading cross-functional initiatives and solving complex organisational challenges.

Equally, experienced Senior Executive Assistants are increasingly making the transition, particularly within founder-led businesses, scale-ups and entrepreneurial organisations. As trusted business partners, many senior EAs already operate well beyond traditional executive support, leading strategic projects, managing executive communications, coordinating leadership teams and driving organisational priorities.

At Biscuit Recruitment, we’ve seen this evolution first-hand. The strongest Senior Executive Assistants often possess many of the qualities organisations seek in a Chief of Staff: commercial awareness, exceptional judgement, stakeholder management, discretion and the ability to translate executive vision into effective execution.

Chief of Staff Salary Insight

Because the role combines strategic oversight, operational leadership and close partnership with senior executives, Chief of Staff salaries often reflect executive-level responsibility.

In London’s competitive recruitment market, remuneration varies considerably depending on the organisation’s size, complexity and stage of growth. Early-stage and scale-up businesses may offer broader responsibility alongside equity, while larger organisations typically provide higher base salaries and bonus structures.

For experienced Chiefs of Staff, the role offers highly competitive compensation packages alongside significant opportunities for long-term career progression into operational and executive leadership positions.

Chief of Staff vs. Executive Assistant

The roles of Chief of Staff and Executive Assistant often work in close partnership, and both are built on trust, discretion and a deep understanding of executive priorities. While there can be overlap in responsibilities, the purpose of each role is typically quite different.

An Executive Assistant focuses on enabling an executive to perform at their best by managing their time, communications, logistics and day-to-day priorities. Beyond diary and travel management, many senior Executive Assistants also act as trusted business partners, coordinating stakeholders, overseeing projects and helping ensure the smooth running of the executive office.

A Chief of Staff, by contrast, operates at a broader organisational level. Rather than focusing primarily on executive support, they help drive strategic initiatives, align cross-functional teams, oversee organisational priorities and ensure leadership decisions are translated into effective execution across the business.

The distinction is less about seniority and more about organisational focus. An Executive Assistant is primarily dedicated to optimising the effectiveness of an individual executive, whereas a Chief of Staff is focused on improving the effectiveness of the wider leadership team and organisation.

As organisations grow, the two roles often complement one another. A Chief of Staff and Executive Assistant can work alongside each other, allowing the Executive Assistant to focus on executive operations while the Chief of Staff concentrates on strategy, alignment and business execution. In some founder-led businesses and scaling organisations, however, responsibilities may overlap, with experienced Executive Assistants taking on increasingly strategic projects as the role evolves.
