The Chief of Staff resume,
and the mandate nobody wrote down.
Chief of Staff is the only senior title on the market with no agreed definition, and that is the whole difficulty. Two people holding it can have spent three years doing unrelated work, and a reader has no way to tell them apart. If the page does not settle the scope in its first four lines, it will be read as the smaller version.
Whose chief of staff, and to do what
The role takes its size from the principal and from the year. Chief of Staff to a founder running sixty people is a different job from Chief of Staff to a group chief executive with fourteen thousand, and both differ again from an appointment made for a merger, a listing or a cost reset. Start with the principal, the organisation they ran, and what they were carrying while you were there.
Then say whether you sat in the leadership forum as a member or as the person taking the note. Both are legitimate. Only one of them is what the word operator means, and blurring it is the quickest way to lose an interview you would otherwise have passed.
The principal's title and span, and the mandate they held during your tenure. Your scope is a fraction of theirs and cannot be read without it.
Whether you had direct reports and a budget. Many of these appointments have neither by design, and saying so plainly reads better than a sentence built to imply otherwise.
Your seat in the leadership meeting — member, secretary or attendee — and whether you held a view in the room or recorded the ones held by others.
The term and its intended exit. Most of these roles run eighteen to thirty months into a line job. Say what yours was designed to lead to, and whether it did.
Decisions owned, decisions carried
The distinction that matters is between what ended with you and what you moved along on somebody else's behalf. Both are real work; only the first reads as authority. The figures below are unusual for a senior page because the role generates few of its own, which is why the ones you have need to be exact.
Decisions that closed without the principal, with the largest by value, because this single line separates an operator from a coordinator faster than any description of scope.
The governance cycle you ran: pack length, how many days ahead it circulated, and the share of agenda time spent deciding rather than updating, given at both ends of your tenure.
An initiative delivered through people who did not report to you, with the workstream owners counted and the result stated, because influence without authority is the trade and it can be measured.
The planning cycle: units covered, objectives set, objectives killed, elapsed weeks — because a process that never drops anything is documentation rather than planning.
Any period you held a line function outright while a gap was open, and what it did under you, because interim ownership is the plainest proof the job was operating rather than administrative.
Where the role led, for you and for your predecessor, because a chief of staff appointment is priced on its exit and a line job afterwards settles the question the title leaves open.
Sentences that read as support
Each line below describes proximity to power rather than the use of it. They are the reason capable people in this role get shortlisted for programme jobs they never wanted.
“Trusted advisor to the CEO.” Proximity, not output. Give a decision that went differently because of your work, and what the difference was worth.
“Managed strategic initiatives across the business.” Managed is doing a great deal of hiding. Split the list: which you owned outright, which you coordinated, and the outcome of one from each column.
“Prepared board materials and executive communications.” Preparation is production. Say what the board then did — an item brought forward, a metric added that changed the argument, a paper withdrawn because the analysis did not hold.
Three lines, rewritten.
The same fact, made checkable. Every figure is illustrative of the shape an evidenced line takes — nothing here is invented on your behalf.
The claim on the left is not wrong. It is simply unreadable as evidence: nothing in it can be checked, compared or priced. The version on the right makes the same statement in a form a search partner can act on.
Served as Chief of Staff to the CEO, supporting strategic priorities across the business.
Chief of Staff to the chief executive of a 2,400-person software company through an eighteen-month cost reset. Member of the eight-person leadership team. Owned three of the year's nine priorities outright — pricing, the partner channel and the office consolidation — and carried the other six as governance.
Managed the board reporting process and the executive meeting cadence.
Cut the board pack from 140 pages to 34 and moved circulation to six working days ahead of the meeting rather than the night before. Agenda time spent on decisions went from a quarter to two thirds. The June and September boards each closed an item that had rolled three times; the second was a $9M capital approval.
Drove cross-functional initiatives to improve operational efficiency.
Ran the integration of a 90-person acquisition with nobody reporting to me: 11 workstream owners across 5 functions, weekly for 7 months. Both businesses on one billing platform by month 5, $3.1M of a $3.6M synergy case delivered by month 12, and 4 of the 6 named leaders still in post after the earn-out.
