The right time is before execution starts to slip
A growing life-science company can need experienced operating leadership before it needs a full-time chief operating officer. Scientific progress creates new demands: more external partners, larger commitments, additional employees, and infrastructure decisions that affect several functions at once. The CEO becomes the default coordinator, while scientific leaders spend increasing time resolving issues outside their primary responsibilities.
A fractional COO can help when those demands are recurring and interconnected, but the leadership workload can still be managed through a defined part-time commitment. The signal is not a particular headcount or funding round. It is a gap between the complexity of the work and the company's ability to coordinate and execute it reliably.
Engage early enough to influence consequential decisions—not only after a missed milestone, a problematic move, or an expensive system implementation makes the gap visible.
Define the role before choosing the title
A fractional COO is an experienced operating leader engaged for a defined portion of their time, with agreed responsibilities and decision authority. The intended contribution is ongoing leadership and follow-through, not simply recommendations delivered at the end of an assessment.
That distinction matters. An advisor may help leadership evaluate choices. A project manager may organize a defined initiative. An interim COO may fill a temporary executive vacancy, potentially full time. Fractional leadership is most useful when the company needs sustained cross-functional ownership at a level of commitment below a full-time role.
The mandate should fit the business. It may include operating cadence, infrastructure, vendor oversight, resource coordination, or execution of a growth plan. It should not imply that one person replaces every specialist. Scientific, clinical, Quality, Finance, and other functional leaders retain their respective responsibilities unless an explicit organizational decision changes them.
Recognize the timing signals
Look for patterns rather than one busy week:
- The CEO repeatedly resolves routine dependencies between functions because nobody else has a clear mandate.
- Teams agree on strategic priorities but lack a shared execution plan, owners, and decision dates.
- Facilities, systems, hiring, and vendor commitments are being made separately despite depending on one another.
- External partners are multiplying, but oversight and escalation still depend on individual relationships.
- A new site, development milestone, or organizational transition requires more coordination than existing leaders can absorb.
- The same operating problems return because immediate fixes never become dependable processes.
These signals do not automatically justify a COO. First ask whether the constraint is a missing specialist, insufficient delivery capacity, unclear priorities, or a genuine cross-functional leadership gap. A fractional executive should address the actual problem, not add a title over an unresolved one.
Put experienced judgment ahead of irreversible commitments
Consider an illustrative biotech company preparing to expand laboratory operations while advancing a development program. Its scientific team is selecting equipment, Facilities is planning space, IT is evaluating systems, and Finance is managing available resources. Each workstream has a capable owner, but their assumptions and timelines do not yet align.
A fractional COO could bring those owners together around one operating plan: establish the critical dependencies, sequence decisions, identify readiness requirements, and make tradeoffs visible to the CEO. The role is not to redesign every function. It is to ensure that decisions made in one area do not quietly prevent another area from delivering.
Engaging before equipment orders, lease commitments, or system selections are finalized preserves more options. Engaging later may still help, but more of the work becomes recovery and rework rather than deliberate preparation.
Make the benefits observable
The potential benefit is access to experienced operating judgment at a commitment appropriate to the company's needs. It may also create more focused time for the CEO and scientific leaders, clearer accountability, and earlier visibility into execution risks. None of those outcomes follows from the title alone.
Translate the engagement into results the leadership team can assess:
- Important decisions have owners, sufficient information, and agreed deadlines.
- Cross-functional dependencies are resolved before they delay critical work.
- Operating commitments and resource constraints are visible in one shared plan.
- Escalations reach the right person, with options rather than surprises.
- Repeat problems lead to practical process improvements and internal capability.
Compare the full cost and coverage of fractional leadership with the alternatives. A lower time commitment is not automatically lower total cost if the scope exceeds available capacity or employees must continually fill the gaps. Agree on availability, response expectations, and how urgent issues will be handled outside scheduled time.
Establish authority, boundaries, and a review point
Before starting, document the business problem, executive sponsor, decision rights, functional boundaries, and expected deliverables. The CEO should explain the role to the team so the fractional COO has a clear mandate rather than informal influence alone.
A practical initial engagement can begin with a review of the operating model and a short list of priorities, followed by implementation and a scheduled assessment of results. Define what will be delivered, who must participate, and what evidence will show progress. Avoid an open-ended mandate to “fix operations.”
For broader context, McKinsey's discussion of the COO agenda emphasizes connecting operations to business strategy and defining the executive's role in execution. Those principles are useful for scoping a fractional engagement; they are not evidence that a fractional model suits every company.
Know when a full-time role is the better answer
A fractional arrangement becomes less suitable when the company needs continuous executive coverage, substantial daily people leadership, or rapid decisions across several simultaneous operating fronts. It may also be a poor fit when the proposed scope depends on authority that leadership is unwilling to delegate.
If the work consistently exceeds agreed capacity, revisit the model rather than normalizing gaps in coverage. The next step may be a full-time COO, a stronger internal operations team, or a dedicated functional hire. Plan knowledge transfer and succession from the beginning so the engagement strengthens the organization rather than creating another single point of dependency.
Operational takeaway: engage for a defined leadership gap
Identify the cross-functional decisions and recurring execution problems that currently fall back to the CEO. Determine which require executive judgment, which require specialist expertise, and which simply need additional capacity.
If the gap is sustained operating leadership at less than a full-time workload, define a fractional COO mandate with clear authority, availability, outcomes, and a review date. Bring that leader in before major commitments narrow your choices. Success is not more meetings or another executive title—it is a company that makes sound decisions and follows through more reliably.
