The Public Sector Talent Cliff
How Succession Planning Can Help Government Agencies Secure Their Futures
One of the most urgent challenges facing government agencies today isn’t political or budget-related – it’s the demographic reality of an aging workforce. A significant portion of the seasoned workforce is eligible for retirement, and their impending departure risks leaving agencies not only with vacant roles, but also without the deep knowledge, skills, and experience critical to delivering essential services for people across the country.
Many organizations now face an inevitable talent cliff. Without shifting from reactive hiring to proactive, data-driven succession planning, they risk real threats to service continuity, institutional stability, and operational performance in the coming years.
Why This Matters Now
The timeline is short. In the next five years, up to 30% of the federal workforce will be eligible to retire according to the Office of Personnel Management; with state and local governments not far behind. Each unfilled critical role has a real cost: Some studies estimate that a single vacant role can cost up to $25,000 per month in lost productivity. For highly specialized public sector positions – like a SNAP program administrator or a lead safety inspector – the impact is even greater and often extends far beyond financial loss.
In our work with various organizations, we have seen that effective succession planning strengthens more than business continuity. One agency used succession planning to help cultivate a stronger culture of learning and development for the organization. Another utilized succession planning to improve retention of high performers by clearly demonstrating investment in employee development and leadership pathways.
No matter the goals, one thing is clear: modern HR teams need a standardized succession planning process to avoid the costly consequences of the talent cliff. The good news is that building such a function is achievable by following a systematic, measurable framework that involves identifying critical roles, understanding key role attributes, identifying potential successors, and investing in targeted training and development.
Cultivating a Strategic Talent Pipeline
Many organizations mistake replacement planning for succession planning. While these sound similar, replacement planning identifies a “backup” person/people to step in if a leader leaves. It is focused on immediate continuity. Where replacement planning falls short is in its lack of proactive development and preparation of its identified talent pipeline, including the transfer of knowledge, skills, and experiences critical for success in a given role.
Effective succession planning goes far beyond choosing who might fill a job in an emergency. It focuses on building capability, preparing multiple candidates, and growing organizational leadership capacity over time. It is a continuous process of identifying critical roles, defining what makes people successful in those roles, selecting potential successors, and deliberately preparing them.
Once critical roles have been identified, successful organizations follow a five-step process toward building sustainable talent pipelines that promote continuity in these roles not just for the next turnover, but for ongoing talent cultivation.
1. Identify the Knowledge, Skills, and Experiences (KSEs) required for critical roles
Roles aren’t defined just by their duties – they are shaped by the knowledge, skills, and experiences (KSEs) that enable incumbents to be successful. These are almost never fully captured in job descriptions. Through interviews with high-performing leaders, we often uncover KSEs such as stakeholder influence, policy acumen, or crisis decision making – attributes not listed in formal qualifications but essential for success. Identifying these KSEs sets the foundation for a successful succession planning process.
2. Broaden the Successor Pool
Relying on a single successor for a critical role creates a high-risk talent scenario, increasing the chance of operational disruption. Organizations should aim for at least three viable candidates per critical role to mitigate risks from unexpected turnover, internal mobility, or a candidate’s lack of readiness or interest when a role becomes available. Strong successor pools typically include:
- Direct reports
- Employees in similar career paths
- High performers with potential to advance
Potential candidates should demonstrate strong performance in their current role and potential to succeed in the future role. While participation should be voluntary (“opt-in”), being identified as a potential successor is not a guaranteed placement. Instad, it signals an opportunity for growth and investment.
3. Evaluate candidates based on role KSEs
Once a successor pool is identified, successor candidates should be assessed based on the KSEs necessary for the role they are being considered for. While evaluations are typically completed by a candidate’s direct manager, self-assessments and calibration sessions can also be used to enhance a fair assessment process. Those candidates who possess a minimum of 75% of the KSEs for a given role are determined to be ‘ready successors;’ meaning that while some development may still be needed, we can express confidence that these individuals could step into a role with relative success should the need arise. Those assessed to have met 50-75% of the KSEs for a role become ‘ones to watch,’ meaning they have potential but may need more experience or skill building before they are ready to step into a given role. Those who do not meet at least half of the KSEs are not considered further at the given time.
- Implement Targeted Development
Once high-potential candidates are identified, the organization should support “ready successors” in developing Individual Development Plans (IDPs) designed to address remaining gaps in Knowledge, Skills, and Experiences (KSEs). The most effective IDPs move beyond traditional training to focus on experiential activities and knowledge transfer that combines training and professional development, conferences and networking, shadowing, and direct mentorship. For example, one IDP creation session we supported for a CFO role was invited to weekly leadership finance meetings and a national conference – real-world exposure that significantly accelerated their readiness.
- Build a Sustainable and Ongoing Process
Succession planning should become a routine part of HR operations – not a one-time initiative. The most successful organizations we’ve supported review pipelines at least annually, refresh KSEs as roles evolve, track IDP progress, and prepare both individuals and teams for long-term leadership needs.
These organizations have succeeded in reducing turnover disruption, preventing costly external searches, and building a more motivated, growth-oriented culture.
Measuring the ‘Succession Health’ of the Organization
Leading organizations that have built effective processes around succession planning also benefit from a clear view into the ‘Succession Health’ of their organization by developing a clear picture of where the organization is vulnerable and where the talent pipeline is strong. We have supported organizations to measure succession health via a Talent Heat Map – a dashboard that visualizes organizational risk by correlating Incumbent Retirement Eligibility with Successor Readiness through the use of ‘Red’, ‘Yellow’, and ‘Green’ role classifications. This allows leaders to triage resources, targeting ‘Red’ roles (high risk, low successor readiness) for immediate external acquisition strategies while reinforcing pipelines for ‘Yellow’ roles.
Technology as an Enabler
An increasing suite of Artificial Intelligence (AI) tools can minimize succession disruptions and enhance the planning process. Knowledge management tools create a living repository for institutional knowledge, while innovative platforms help manage the hyper-customized Individual Development Plans (IDPs) needed for potential successors. New tools can also help broaden successor identification by locating qualified internal candidates in unexpected parts of the organization – e.g., someone qualified for a program director role currently sitting in Finance. While these tools increase accuracy and accelerate processes, person-to-person mentorship and development remains the key to effective succession planning.
The Bottom Line
Moving from reactive hiring to proactive talent pipeline development is essential for every organization. Strategic succession planning ensures continuity of mission, reduces risk, strengthens culture, and prepares the next generation leaders.
Taking steps now will help your agency step back from the talent cliff – and build a more resilient and future-ready workforce.
