Beyond the Default Heir: An Evidence-Based Succession Process for Family-Owned Enterprises

The governance question is access, not ancestry

A succession committee can inherit a decision before it ever conducts an interview. The oldest child may have attended board meetings for a decade, while a younger sibling or daughter was never offered comparable exposure. A later assessment can then mistake unequal preparation for an innate difference in leadership potential. Custódio and Siegel's study makes this possibility worth examining, but does not establish that it explains any particular family's appointments. The useful response is to inspect access to development and the evidence used in selection, rather than to infer competence from a candidate's position in the sibling order.

This companion proposes a process for a family office overseeing a controlled operating business or coordinating an ownership transition. It does not propose a birth-order scoring model. Ownership entitlements, family identity and readiness to manage an enterprise are different questions. A person may retain ownership and a voice in family governance while choosing not to seek the chief executive role. An external executive can be appropriate even where the family intends to retain control. Those options should be explicit before succession becomes an emergency.

What the study actually supports

The main analysis uses 141 CEOs of small and medium-sized United States businesses who had siblings. They responded to a birth-order survey circulated through Vistage in 2013. The sample contained 110 men and 31 women, and its response rate was approximately eight percent of the CEOs invited. The authors compare observed birth-order frequencies with expected frequencies based on respondents' sibling counts. This is not a prospective experiment in which otherwise equivalent candidates were assigned different family positions. It is a comparison within a selected population of people who already became CEOs.

The researchers report an observed first-born share of about 45 percent, compared with an expected share of about 30 percent. The difference is more pronounced in the small family-firm subsample, and the gender composition of siblings matters to the observed patterns. Additional analyses using a larger CEO survey and Swedish administrative evidence support a smaller first-born association. Importantly, the authors do not find evidence in their main sample that first-born CEOs achieve better return on assets or sales growth, or earn higher incomes. That absence of evidence is not proof of equal performance: the authors explicitly note limited statistical power.

These results motivate questions about selection and development, not predictions about an individual. The paper does not evaluate family offices, investment committees, wealth preservation, or the governance protocol proposed here. The family-firm subgroup is small, birth-order definitions differ across the validation exercises, and the observational design cannot establish causation. The proposed controls therefore stand as transparent governance choices to be evaluated locally, rather than as experimentally validated methods for improving returns.

First decision: define the job before discussing the heirs

The board chair should commission a written role specification before soliciting candidate preferences. Define the operating challenges over the next three years: liquidity management, customer concentration, technology renewal, workforce continuity, or integration of an acquisition. Convert each challenge into observable responsibilities and evidence requirements. For example, a liquidity requirement could ask every candidate to explain a downside cash-flow case and the actions that would protect covenant headroom. The purpose is to evaluate relevant judgment, not to reward a polished family narrative.

An independent director or external assessment lead should record criteria and their relative importance before seeing candidate rankings. Family connection, birth order and gender must not serve as competence proxies. Where a family member has a genuine conflict, record the conflict and use an assessor with appropriate independence. If the criteria are revised after a preferred candidate emerges, stop the ranking exercise and require a documented board decision explaining why the business need changed. Preserve both versions so that retrospective tailoring is visible.

Second decision: repair development gaps before treating them as ability gaps

The family office's governance lead should map meaningful development opportunities over the preceding years: operating responsibilities, budget authority, board observation, mentoring, external employment and exposure to lenders or customers. Ask each willing candidate to confirm the record. An invitation to a dinner is not equivalent to accountable operating experience. Track the duration, responsibilities, feedback and outcomes of each assignment. Do not infer that a person declined a career opportunity when the family never offered it clearly.

Offer comparable opportunities where practical, with adaptations for legitimate availability constraints and the needs of the business. A candidate lacking a required experience should receive an explicit route to acquire it, or an explanation of why the time available makes that route infeasible. This does not require delaying a necessary professional appointment to manufacture parity. The board can select an interim or external leader while developing future candidates. Stop a developmental assignment when it endangers staff, customers or the firm's financial position; a family learning objective cannot justify unbounded business risk.

Third decision: compare evidence under the same conditions

The assessment lead should use the same business case, information access and preparation window for all shortlisted candidates, while allowing reasonable accommodations. Ask candidates to identify assumptions, describe what would change their minds, and set escalation thresholds. Obtain references about actual responsibilities and conduct, not only endorsements from family allies. Record reasons for each judgment and distinguish directly observed behavior from hearsay. The committee should challenge a recommendation that relies on statements such as always destined to lead or naturally the responsible sibling.

Separate the appointment discussion from an ownership, inheritance or distribution negotiation. If those matters must be coordinated, use distinct records and appropriate professional advisers so that a concession in one domain is not disguised as proof of executive capability in another. Pause the appointment if unresolved conflicts prevent a credible comparison, essential evidence cannot be verified, or a candidate will not accept accountability. The default response to uncertainty is an interim governance arrangement with a review date, not a permanent appointment presented as inevitable.

Fourth decision: test the process without creating a family ranking database

The board secretary should keep a confidential succession decision record containing the role specification, criteria, development offers, evidence, conflicts, dissent, appointment rationale and review dates. Personal family information should be collected only where needed for a legitimate governance purpose and handled under applicable privacy requirements. This protocol does not require collecting siblings' birth order or building demographic profiles for recruitment. Reviewing whether opportunities were consistently offered is more useful than constructing a pseudoscientific score from family history.

Measure process quality through completeness of evidence, proportion of candidates offered documented development, unresolved conflicts, departures from precommitted criteria and timely completion of review actions. Track post-appointment operating outcomes against the approved business plan, including cash performance, employee retention and execution of strategic milestones. Do not attribute a change in those outcomes to this protocol without a credible evaluation design; market conditions and inherited business quality also matter. A fairer process is a governance objective in its own right and not a guaranteed source of excess returns.

Review and stopping conditions

At an agreed review point, the independent chair should ask whether the selection record can explain the decision to a reasonable owner who did not participate. Invite candidates to flag factual errors and procedural concerns through a route that does not depend on the successful candidate. Reopen an assessment when material evidence was false, a conflict was concealed, or the role has changed substantially. Do not reopen merely because a disappointed relative dislikes a properly documented outcome. Distinguish correction of process defects from permanent relitigation.

The practical lesson is restraint in both directions. The paper supplies no basis for preferring first-born applicants, and it supplies no basis for excluding them as beneficiaries of presumed advantage. It supports examining an underappreciated pattern while leaving individual decisions to relevant evidence.
