The role is open. The work is not.
An operations executive leaves. A permanent search begins. The leadership team agrees to divide the responsibilities temporarily.
Within weeks, the CEO is resolving more cross-functional decisions. Functional leaders are carrying additional work. Company priorities still have owners on paper, but nobody is integrating the complete operating picture.
The business cannot pause while the org chart catches up.
An Interim COO can step into that gap with temporary executive authority. The purpose is not merely to keep the seat warm. It is to protect the outcomes, decisions and operating systems that cannot drift while the company determines what leadership it needs next.
What does an Interim COO do?
An Interim COO temporarily owns the operating responsibilities defined in the mandate.
Depending on the company, that may include:
- Company priorities and operating cadence
- Cross-functional execution
- Leadership-team accountability
- Resource and capacity decisions
- Customer-delivery or operational performance
- Transformation programs
- Escalation and risk management
- Board or investor operating updates
- Preparation for the permanent leadership structure
The Interim COO should be able to make decisions, direct the work and remain accountable for results. Without authority, the role becomes a senior coordinator while the CEO remains the real operating owner.
When an Interim COO makes sense
An operations leader departed unexpectedly
The company needs immediate continuity while it assesses the role, searches for a successor and protects current priorities.
A permanent search will take time
The right executive search should not be rushed simply because the business needs leadership now. Interim coverage separates the urgent operating need from the long-term hiring decision.
The company is entering a consequential stage
A fundraise, acquisition, restructuring, enterprise launch or rapid scale period may require more operating ownership than the current leadership team can provide.
The long-term role is not yet clear
The company may know that execution is breaking without knowing whether the permanent answer is a COO, Chief of Staff, VP Operations or a redesigned leadership structure.
An experienced interim operator can solve the immediate problem while producing better evidence for that decision.
The CEO needs temporary operating leverage
Fundraising, strategic sales, board management or a company transition may make it impossible for the CEO to remain the default operator across the business.
Interim COO vs fractional COO
The distinction is primarily about coverage, authority and operating need—not seniority.
Interim COO
An Interim COO often provides full-time or near-full-time executive coverage for a defined period. The operator may occupy the formal role, lead the executive team and carry broad authority until a transition is complete.
Fractional COO
A Fractional COO usually works part-time against a defined operating mandate. They may own the company operating system, specific cross-functional outcomes or a stage of scale without replacing every responsibility of a full-time executive.
Choose based on the work:
- How much of the operating function needs ownership?
- How quickly must decisions be made?
- Does the operator need formal executive authority?
- How much weekly coverage does the business require?
- Is the gap broad or concentrated around a defined problem?
Fract75 supports fractional and interim leadership as well as permanent placement. Most fractional operators work 10–25 hours per week, but that is a common model—not the limit of what can be deployed.
What the Interim COO should do first
1. Establish the current state
The operator needs a fast, evidence-based view of:
- Company objectives and runway
- Operating performance
- Customer and delivery risk
- Current strategic initiatives
- Leadership responsibilities
- Decisions waiting for ownership
- Team capacity and critical roles
- Existing commitments to the board, investors or customers
The first objective is not to redesign everything. It is to understand what cannot be allowed to fail.
2. Clarify authority with the CEO and board
Temporary roles create confusion when authority remains implied.
Document:
- What the Interim COO owns
- What remains with the CEO
- Which decisions require board involvement
- Which leaders report to or take direction from the operator
- Which budgets and resources they control
- Which risks require escalation
- How disagreements will be resolved
The leadership team should hear the same explanation directly.
3. Stabilize the operating cadence
The company needs a reliable rhythm for priorities, performance, risks and decisions.
The Interim COO may need to restore or install:
- Leadership-team reviews
- Company-priority reviews
- Functional operating reviews
- Decision and escalation paths
- Performance reporting
- A shared view of milestones and risk
Stability does not mean freezing the company. It means creating enough clarity for work to continue.
4. Protect the critical outcomes
Identify the few outcomes that matter most during the transition.
These may include revenue delivery, customer retention, a product launch, margin improvement, hiring, a fundraise or a transformation already underway.
Assign clear owners, confirm capacity and resolve the decisions that could stop them.
5. Diagnose the long-term operating need
The interim period should produce information the company can use.
The operator can help determine:
- Whether the COO role should remain
- Which responsibilities belong together
- What seniority the permanent leader requires
- Which systems or capabilities are missing
- Whether part of the work can remain fractional
- What the next leader should inherit
The answer should emerge from the company’s actual operating needs—not from the previous title.
Common mistakes
Giving the interim responsibility without authority
The company announces an executive owner while every decision still returns to the CEO.
Treating the operator as a caretaker
Avoiding every meaningful change can preserve the problems the permanent leader will inherit.
Asking an existing leader to do two executive jobs
This can create exhaustion, divided attention and weaker performance in the leader’s original function.
Beginning the search before defining the mandate
Replacing the departed title without examining what the company now needs can repeat an outdated structure.
Allowing the interim role to become indefinite
Set review points, transition conditions and a decision horizon even when the precise end date is unknown.
What a useful mandate sounds like
“Cover operations until we hire” leaves too much undefined.
A stronger mandate is:
Assume temporary executive ownership of company operations, protect the current revenue and delivery priorities, restore leadership accountability and determine the operating structure the company needs for its next stage.
The mandate should include authority, reporting line, coverage, outcomes, risks, milestones and the expected transition path.
Plan the handoff from the beginning
The Interim COO should leave the next leader with:
- A clear view of company priorities
- Current operating performance and risk
- Documented decisions and commitments
- Defined leadership responsibilities
- A working operating cadence
- Systems and reporting the company trusts
- A record of unresolved issues
- A practical first-90-day agenda
The transition should transfer context and capability—not simply a calendar full of meetings.
What the company should retain
- Operating continuity during the gap
- Clearer executive decision rights
- Protected company priorities
- Stronger leadership accountability
- A diagnosed long-term operating need
- Better information for the permanent search
- Systems and documentation the next leader can use
- Less dependence on the CEO as the fallback
The interim mandate succeeds when the company keeps moving and makes its next leadership decision from a stronger position.
