What one CNO's path from bedside to executive teaches administrators about succession
When Vanderbilt University Medical Center named Deonna Taylor vice president and chief nursing officer of Adult Ambulatory Nursing, it doubled as a succession-planning case study. Taylor began as a bedside nurse on a transplant unit in 2003, earned an MSN in 2018, and was featured in HealthLeaders' "The Exec" on September 21, 2026. For nurse administrators, her path is a pipeline playbook, not a career profile: early entry points, talent spotting, mentorship, internal versus external hires, metrics, and next-gen finance and AI skills. Leadership pipelines do not begin at the vacancy; they signal leaders invest in nurses' growth.
Some organizations treat succession as a reactive process: a vacancy appears, then the search starts. Others treat it as a pipeline that opens years before the office is empty. Deonna Taylor's trajectory at Vanderbilt University Medical Center is the second model.
In 2003, Taylor began as a bedside nurse on a transplant unit at VUMC.2 As a first-generation college student, she completed an MSN from Vanderbilt School of Nursing in 2018 and later earned a PhD in health services research.2 In 2026 she became vice president and chief nursing officer of Adult Ambulatory Nursing after serving as interim CNO from February 2026.1
In her HealthLeaders The Exec profile, Taylor highlights three priorities: educational pipelines that start in high school, succession planning that begins before a vacancy exists, and intentional early leadership development. She also links these pathways to engagement, noting that nurses see leaders care about their growth when structured development is visible. Those pathways serve both the organization and the individual, because they convert retention into a visible investment in career progression rather than a promise made after high performers have already decided to leave.
The lesson is not that every future CNO needs the same clinical-to-academic sequence. It is that a long internal runway is a design choice, not luck. Vanderbilt's adult ambulatory partnership with TCAT Nashville, which creates a medical assistant to LPN advancement track, reinforces that early entry points can be built systematically.3 The HealthLeaders The Exec profile, published September 21, 2026, provides the full interview for deeper context.
Leadership turnover is not a vacancy problem; it is a recurring financial drain that too many nursing budgets treat as an unavoidable cost. The 2026 numbers make the case plainly. According to Vizient, an average acute care hospital loses $4.75 million annually to turnover-related costs. A single nurse manager departure carries a price tag of $132,000 to $228,000, yet many organizations have no line item for developing the next one. That range alone could fund months of structured leadership development, such as a graduate certificate in nursing administration, rather than one unplanned replacement.
Vizient's 2026 synthesis of AONL and Laudio Insights reports that 12% of nurse managers intend to leave their roles, 9.5% are already exiting, and turnover sits at 7.5%. Most exits occur within the first four years, driven by role clarity, workload, and compensation misalignment. Those are pipeline failures, not personality mismatches. When early exits happen, the organization has already paid for onboarding and initial development, then pays again to recruit and train a replacement.
An open nurse manager position triggers recruitment fees, interim coverage, overtime pressure, and lost momentum on unit goals. NSI's cost range captures direct replacement expense, but the $4.75 million hospital-level figure shows compounding effects. Registered nurse turnover remains 17.6%, with a 9.6% RN vacancy rate and only 87.2% first-year RN retention, so manager instability lands on an already stretched workforce. Each interim period also erodes staff confidence and slows quality improvement work.
"Would you rather spend $132,000 to $228,000 replacing one nurse manager after a vacancy, or a smaller annual amount developing three high-potential nurses through nurse executive certification before the vacancy opens?" That trade-off shifts the pipeline conversation from a soft HR program to a risk mitigation budget line, one that frontline nurses read as proof their leaders care about their growth.
At Vanderbilt University Medical Center, Deonna Taylor's pathway began in 2003 on a transplant unit, not in an executive suite. That 23-year internal runway is a reminder that leadership pipelines start with visible, attainable rungs.
High school health-career partnerships, certified nursing assistant roles, and student nurse externships create the earliest on-ramps. Formal academic partnerships with BSN, MSN, and DNP in nursing administration programs then keep those candidates connected to the system. Taylor has pointed to educational pipelines that begin in high school as a core strategy, not an afterthought.
Instead of waiting for someone to volunteer, assign charge nurse, preceptor, unit-based council lead, or committee seats as developmental rotations. Track who receives these stretch assignments and who does not. Intentional distribution prevents the common pipeline problem of informal "favorites" becoming the only future leaders. These early leadership reps build the vocabulary and accountability muscles needed for nurse administrator duties and responsibilities across coordinator, manager, and director roles. The goal is to make first leadership exposure deliberate, not accidental.
Pick one clinical unit and map every early-career leadership opportunity over the next 12 months. Name a preceptor or charge nurse for each high-potential nurse, then review the list monthly. If a named nurse has no assignment, add one within 30 days. This makes Taylor's takeaway concrete: early, intentional development signals that leaders care about growth.
A common mistake is treating the best bedside clinician as the obvious next manager. High-potential identification needs structured, observable criteria rather than reputation alone.
Use AONL's Nurse Executive Competencies as the structure for readiness discussions.1 Its five domains include Communication and Relationship Management, Knowledge of the Health Care Environment, Leadership, Professionalism, and Business Skills and Principles.1 These map to what MSN nurse executive programs build: finance to Business Skills and Principles, communication to Communication and Relationship Management, leadership to Leadership, and professionalism to Professionalism. The Knowledge of the Health Care Environment domain covers regulatory, policy, and systems awareness.
Use structured criteria and multiple raters rather than a single manager's memory. Open nominations so any unit or shift can surface candidates. Audit who gets tapped by unit, shift, tenure, race, and gender to catch patterns. And do not promote only the highest bedside performers. That approach can overlook nurses who would lead teams well but will not be the top task doer. A clear alternate path keeps strong clinicians engaged while filling the leadership pipeline with evidence of potential, not just past performance. Pair this with regular feedback so nurses understand the pathway is real.
Mentorship has shifted from informal advice to a structured pipeline function with explicit roles, time, and sponsorship.
A preceptor handles clinical onboarding for a new registered nurse or new unit. A mentor offers longer term career guidance. A sponsor advocates for the nurse when promotions or stretch assignments are decided. A future leader needs all three, but they should not be the same person if honest mentoring and advocacy are to coexist.
Start by naming the target role, such as assistant nurse manager or unit director, and confirm whether the path calls for an MSN in nursing administration. Then match mentors deliberately by stage or need. AACN's Nurse Mentorship Program runs six months online with two cohorts a year. Louisiana's Nurse Leader Mentorship Program uses nine months online with two monthly webinars. Protect time, for example a monthly or every three week meeting, then add a cohort or fellowship structure for peer learning. Finally, assign an executive sponsor who reviews progress and can create advancement opportunities.
Published program reports often show retention and engagement gains, but promotion rates are published much less frequently. Programs from Norsk Sykepleierforbund and Iowa describe structured contact and reduced isolation2, while promotion data remains thin. Track readiness indicators such as completed development plans, precepting hours, or first charge nurse shifts.
A common failure point is no protected time or mentors who are not trained to guide careers. Without scheduled meetings, mentorship collapses under clinical demands. In ambulatory settings, virtual mentoring can work well because teams are dispersed. In rural settings, shared mentors across facilities help overcome small local pools. In academic settings, mentorship often links to faculty advancement, so the sponsor role becomes especially important. The Canadian Nursing Retention Toolkit advises keeping mentorship outside the clinical setting3 to protect the career focused conversation.
Choosing between promoting from within and hiring externally for a chief nursing officer role is not a personality test; it is a succession planning decision with measurable trade-offs. Evidence from healthcare and executive research shows internal promotions generally ramp faster, fail less often, and enjoy lower attrition, while external hires can bring new capabilities and higher long-term productivity gains after a potentially disruptive transition. Go external when you need a major turnaround, a missing skill set that cannot be developed quickly, or your internal bench is empty. Decide your priority criteria now, before a vacancy opens, so the choice is strategic rather than reactive.
| Factor | Internal promotion | External hire | Key decision question |
|---|---|---|---|
| Readiness and time to productivity | Pre-existing knowledge of organizational systems, processes, and people (2021). In a 2025 study, internal promotions were rated highest more often and reached comparable performance faster. | Took three years to reach comparable performance and were 75% less likely to receive the highest rating (2025). Formal onboarding can move productivity up by two months (2014). | How much time can the organization tolerate before the new CNO reaches full productivity? |
| Success and failure rates | Approximately 9% failure rate in C-suite succession (2015). In a separate evaluation, 76% of executives favored internal promotion. | Approximately 12% failure rate (2015). 65% of executives favored external hire in a separate evaluation. | Is the organization prepared to manage the higher estimated failure risk associated with an external hire? |
| Attrition and turnover risk | Lower attrition: American Express observed externally hired executives leaving at three times the rate of internal promotees over three years (2014). | Higher baseline attrition, but a formal New Executive Career Launch onboarding program reduced attrition among externally hired executives to essentially zero, below the 13.5% industry average (2014). | What formal onboarding, sponsorship, and transition support will be provided during the first 6 to 12 months? |
| Strategic change and productivity gains | May reinforce existing culture and deliver incremental improvement without an initial efficiency dip. | Hospital CEOs produced higher subsequent productivity gains after an initial one-time decline in relative efficiency (2025). Yet outside hires were 61% more likely to be let go and 21% more likely to quit (2025). | Can the organization absorb an initial short-term decline in efficiency in exchange for potentially greater longer-term productivity gains? |
| Cost and transition risk | Lower search and recruitment costs, faster enculturation, but risk of limited fresh perspective. | Broadens the candidate pool but requires more time for interviewing and organizational fit assessment (2021); higher estimated failure risk (2015). | What organization-specific knowledge would an external hire need to acquire, and can the organization tolerate the resulting transition time? |
| Onboarding and enculturation support | 70% of hospital systems required onboarding for internally promoted executives (2013). Peer mentorship and clear role articulation are essential for CNO enculturation (2011). | 69% required onboarding for external hires (2013). Exemplary onboarding practices were associated with a $31,957 improvement in net revenue per FTE (2013). | Will onboarding be treated as a 6-to-12-month process rather than a one-time orientation? |
Use this table as a quarterly scorecard for the leadership pipeline. AONL and succession-planning benchmarks provide a starting point; engagement, span of control, and return on investment are usually set locally because credible national targets are not available. Review each metric by role level and demographic group to catch equity gaps in readiness, promotion, and retention.
| Metric | Formula | What It Tells You | Benchmark or Target |
|---|---|---|---|
| Internal fill rate (AONL) | Internal leadership positions filled / total leadership positions filled × 100 | How effectively the organization develops and advances internal talent. | 60% or greater |
| Leadership time-to-fill (AONL) | Days between vacancy announcement and role appointment | How quickly leadership vacancies are filled. | Fewer than 60 days |
| Leadership turnover (AONL) | Leadership departures during period / average leadership headcount during period × 100 | Rate at which leadership talent is lost. | Below 10% annually |
| Pipeline readiness (AONL) | Departments with documented succession plans / total departments × 100 | Extent to which departments have documented succession plans and participate in leadership development. | 100% of departments with succession plans |
| Ready-now bench strength (healthcare succession planning) | Critical roles with at least one ready-now successor / total critical roles × 100 | Immediate continuity risk and depth of successors who can assume critical roles now. | Set locally |
| Bench strength (succession-planning literature) | Average number of qualified successors per critical role | Depth of qualified successor pool for critical leadership positions. | Two to three qualified candidates per critical position, distributed across readiness timelines |
| Successor coverage (succession-planning literature) | Critical roles with identified successors / total critical roles × 100 | Proportion of critical roles protected by an identified successor. | 80% to 100% coverage; below 70% represents high risk |
| Readiness levels (succession-planning literature) | Classify successors as ready now, ready in one to two years, or ready in three-plus years | How soon each identified successor could assume the target leadership role. | Set locally |
| Time to readiness (healthcare succession planning) | Average months until a named successor meets role criteria | Development time remaining before a successor can assume the role and where development investment is most urgent. | Set locally |
Start succession planning before a vacancy occurs.
Healthcare finance and AI governance are converging on the CNO role faster than most leadership development plans acknowledge. A nurse who can run a unit safely may still lack the budgeting, labor management, and business-case skills that executive roles demand, and AI oversight now requires nurse leaders to validate tools before they touch patients.
Finance is often the quiet gap for clinically strong managers. Pipeline programs should teach budgeting, productivity and labor management, and how to write a business case that connects a staffing or technology request to operational outcomes. Pair each high-potential nurse with a finance mentor and require a rotation through budget preparation, not just budget review. MSN and executive coursework, including online nursing administration programs which do not require the GRE, can reinforce these skills, but the habit forms earlier when managers own a line item and defend it.
Nurse leaders should hold a formal seat in AI governance, with the CNO as sponsor or co-leader. Cross-functional committees usually include nurse executives, nursing informatics leaders, frontline nurses, physicians, quality and safety staff, IT, data scientists, and compliance. Nursing's role spans pre-implementation tool selection and validation, plus ethical guardrails and human oversight. CNOs align AI work with patient safety, HIPAA and privacy, compliance, and clinical workflow. That means reviewing for bias, monitoring safety after deployment, and escalating unsafe performance through established governance channels.
Rotate future leaders through finance and AI governance early. Have them read vendor validation evidence, question productivity assumptions, and sit in on technology decisions from procurement through implementation to evaluation. The site's finance and AI governance coverage offers a starting point for those assignments.
