When CHRO handovers stop being theater and start being mentoring
Two Fortune-listed organizations quietly executed textbook chief human resources officer succession on the same April morning. On April 1, 2024, Parsons Corporation announced that Soo K. Lagasse, previously senior vice president of global talent acquisition and mobility, would become chief human resources officer, while retiring CHRO Susan Balaguer would remain as an advisor through the end of May, as documented in the company’s official press release filed on that date. That “advisor through May” pattern shows how leadership mentoring becomes a concrete succession mechanism rather than a ceremonial farewell. On the same day, Kyndryl Holdings disclosed in its own April 1, 2024 press release that Mark A. Paulek would succeed CHRO Maryjo Charbonnier as chief human resources officer, illustrating how different leadership transitions can still rely on the same underlying mentoring process when the succession plan is well managed and aligned with business strategy, as reflected in both companies’ official communications.
These two leadership moves are not isolated executive events; they are case studies in how organizations convert mentoring into a structured succession planning engine for career development. The Parsons transition shows what happens when leaders treat the CHRO–board relationship, disciplined executive search, and cross-functional exposure as part of a long-term mentoring architecture rather than last-minute crisis responses to CEO succession or unexpected change in the business. For HR and talent leaders, the signal is clear: modern CHRO succession is less about finding heroic individuals and more about building a repeatable process where people are mentored into readiness through deliberate leadership development, workforce planning, and culture-shaping assignments that prepare them years in advance.
The advisor-through-May pattern matters because it formalizes mentoring time between the outgoing chief human resources officer and the incoming successor. Instead of a rushed handover of files and a perfunctory privacy policy briefing, the incumbent CHRO can coach the successor on board dynamics, executive committee rituals, and the unwritten rules that shape how talent and human resources decisions really get made. That mentoring window also lets the new HR chief test their leadership style, stress-test the succession plan, and refine their approach to artificial intelligence, change management, and cross-functional collaboration before they fully own the role and its risks, reducing the likelihood of early missteps. In practice, many boards now expect at least a 60–90 day overlap with clear milestones for relationship-building, strategic alignment, and risk transfer, turning what used to be symbolic theater into a measurable mentoring period.
Internal promotion, hybrid moves, and the mentoring lineage behind readiness
Parsons chose an internal promotion for its next HR chief, elevating Lagasse from a talent acquisition and mobility leadership role into the top human resources seat. That choice reflects years of mentoring, where executive leaders used stretch assignments, international mobility, and cross-functional projects to build a pipeline of promotable CHROs rather than relying solely on external executive search firms to solve succession gaps. Kyndryl, by contrast, used a more hybrid model for its leadership change, blending internal familiarity with external experience to ensure the new chief human resources officer could navigate both legacy culture and future business demands in a complex, global environment.
In both organizations, mentoring is the invisible infrastructure that makes leadership transitions look smooth on the outside. Successors rarely become ready in a single year; they accumulate capability through deputy roles, shadowing the incumbent CHRO at board meetings, and leading complex change management programs that cut across business units and geographies. Years ago, many companies treated the HR chief role as a back-office function, but today’s CHRO succession practices show that leaders now frame it as a strategic executive position where mentoring must cover CEO succession exposure, business strategy fluency, and the ability to orchestrate leadership development at scale across the enterprise.
For HR directors designing mentoring programs, the Parsons and Kyndryl examples highlight three concrete mechanisms. First, embed mentoring into the formal succession planning process so every named successor for any executive role has a clear advisory period with the incumbent and measurable leadership development goals tied to workforce planning and talent outcomes. Second, use mentoring to give emerging leaders repeated access to the CHRO–board interface, where they can practice framing human resources data, artificial intelligence initiatives, and culture shifts in terms that resonate with CEO and board expectations, building confidence before they step into the spotlight. Third, define a simple readiness checklist for each successor that includes exposure to at least one major restructuring or transformation, participation in a board-level talent review, and ownership of a cross-functional initiative where they must balance people, technology, and financial trade-offs.
Mentoring as the career accelerator inside CHRO succession planning 2026
Mentoring becomes a career development engine when it is wired directly into CHRO succession planning 2026 rather than offered as a generic leadership perk. In practical terms, that means every potential successor for the CHRO role, and for other executive positions, receives structured mentoring on three fronts: political continuity, technical mastery of human resources and workforce planning, and the narrative skills to explain change to people, leaders, and the board. When organizations treat mentoring as a core part of the succession plan, they create a repeatable path where people officers and other senior HR leaders can move from specialist posts into enterprise-wide leadership roles without losing cultural continuity or strategic focus.
Political continuity, not capability, is often the real bottleneck in leadership transitions, especially in the CHRO role. A successor may have strong talent expertise and a solid grasp of artificial intelligence in HR, but without mentoring on how the CEO thinks, how the board reads risk, and how the business strategy has evolved over the past years, they will struggle to sustain trust during the first critical months. The advisor-through-May pattern at Parsons shows how a well-managed mentoring window can transfer that political capital, giving the new chief human resources officer time to build their own relationships while still drawing on the incumbent’s credibility and institutional memory.
For HR and talent directors, the immediate question is operational: how do you hard-wire mentoring into your own CHRO succession planning 2026. Start with your next talent review and ask which potential successors for executive roles have had formal advisory time with the incumbent, and which leaders have been mentored through real cross-functional crises rather than classroom simulations. Then redesign mentoring so it becomes the spine of your succession planning, not engagement slides but signal, supported by evidence such as Deloitte’s Global Human Capital Trends research, which has repeatedly found that organizations with strong leadership pipelines are significantly more likely to hit their performance targets, underscoring why structured mentoring is now a strategic necessity.
Key quantitative insights on mentoring, retention, and succession
- Recent industry analyses, including 2023 research from Gartner on talent and leadership development, indicate that employees with a formal mentor show materially higher retention than peers without one, directly linking mentoring to succession stability and continuity in critical roles.
Key questions HR leaders are asking about mentoring and CHRO succession
HR leaders consistently ask how long the ideal advisory overlap should last, which capabilities distinguish a future-ready CHRO from a strong HR business partner, and how to measure whether mentoring is genuinely accelerating readiness rather than simply adding meetings to already full calendars. As one senior HR executive quoted in Deloitte’s Global Human Capital Trends series observed, “Succession only works when mentoring is visible, intentional, and measured,” capturing the shift from informal sponsorship to disciplined, evidence-based development.
