How to Know if Succession Planning is Working in 2026 and Beyond

Succession planning is top of mind for many HR leaders in 2026, but building a winning strategy takes more than good intentions. About 4 in 10 talent management executives cited creating a succession strategy as a top focus area for 2026, according to SHRM’s 2025 Talent Management Executives: Priorities and Perspectives research.

For HR leaders looking to build their strategy, and measure success, it’s important to understand that winning succession planning in 2026 and beyond is strategic, organization wide, and data-driven, rather than reactive, siloed, or based on intuition.

Succession as an Interconnected System

The strongest succession plans share one defining trait: They treat succession as a long-term, evergreen system rather than a series of urgent, one-off decisions.

For Deb Rubin, senior partner and head of CEO and board services at RHR International, a leadership consulting firm headquartered in Chicago, succession planning should be an evergreen process where the pieces interconnect, rather than a series of urgent, one-off decisions.

“You want to think of [succession planning] over time,” Rubin said. Some choices are immediate — who fills an open role, who enters a development track — but these should feed a much larger strategic engine.

The leaders you cultivate today become your options for critical roles tomorrow, and that pool becomes the field from which your next critical leader, like a CEO, emerges. Each layer depends on the others, which is why the most effective HR executives are “thinking about those as interdependent systems,” according to Rubin. For HR leaders, there are four ways to tell if your succession planning strategy is working well.

HR is in Alignment with Senior Leaders

Data and metrics can tell one side of the story when it comes to succession planning, but alignment between HR and senior leaders tells the other half. “The number one question is, is there strategic alignment?” said David Reimer, CEO and managing partner of The ExCo Group, a consulting firm headquartered in Arlington, Va. “Is there a shared strategic narrative that, literally, you can probe three layers down and people are telling a unified story?”

These stakeholders must agree on succession planning as a strategic priority. This alignment is not something you measure on a dashboard, yet it shapes every decision that follows. “If the business leaders and HR are aligned on succession planning as a strategic imperative, that’s going a long way to drive choices and conversations that lead to making good decisions that work now and in the future,” Rubin said. 

Finding alignment with senior leaders requires HR leaders to speak the language of the C-suite. This means quantifying what succession planning delivers and what neglecting it costs. Compensation premiums for external hires, search fees, ramp-up time, and the loss of talented people who see their paths blocked all carry real financial weight.

Rubin also suggested quantifying the opportunity cost of deprioritizing success planning strategy. “One opportunity cost is what you lose in terms of the traction and momentum on key initiatives,” Rubin said. Translating the impact of the lack of strategy for senior leaders can help keep it top of mind, especially when the daily pressures of running a business compete for attention.

Objective Data Wins Over Subjective Judgment

Once alignment exists, the quality of your decisions depends on the quality of your data. The critical question is straightforward: “Are these processes built on objective assessment of these individuals,” Rubin said. “Or is it subjective?” The distinction matters.

To get to an objective assessment, Reimer emphasized the importance of math, tallying up key roles in an organization. “Do you know the top 20, 25, or 50 critical positions in your company?” Reimer asked. “Not the 25 most senior people, but the positions that actually move the strategy.” 

Objective data is important because subjective processes carry hidden costs. They lean on impressions, reputation, and familiarity rather than evidence. “[Subjectivity] tends to perpetuate unconscious biases and tendencies that pretty much lock a company in the past,” Rubin said. It also encourages leaders to reward past performance as if it guarantees future success, which it rarely does when a new role brings greater scale, complexity, or ambiguity.

An objective approach changes what you can see. When you assess leaders systematically, you gain data that predicts who can grow rather than assumptions about who has succeeded before.

Potential is Replaced With Scalability

Even organizations that gather good data often measure the wrong thing. “Potential" sounds strategic, but it collapses under scrutiny. Business priorities shift so quickly that naming a future role for someone five years out is often guesswork, according to Rubin. 

A sharper construct is scalability. “The ability to scale is probably a more helpful construct than potential,” Rubin said. Scalability asks whether a leader can handle bigger, more demanding responsibilities as your organization grows and changes. That question is answerable, and it points directly to development needs.

Assessing scalability means examining specific capabilities. “Can they manage and influence stakeholders? Can they see the enterprise view? Can they handle ambiguity and navigate it well?” These dimensions provide objective data to help you distinguish high-scalability leaders from those who need targeted development, and they help you invest where the return is greatest.

Outcomes are Measured, Not Just Lists

A succession plan proves its worth through results, not documentation. The signs of a working system are visible if you look. Rubin suggested “looking at succession lists and see how many people have been in a ready now category that keep getting passed over.” Repeated stalls signal that your assessments or decisions are broken somewhere.

Gathering data is the first step. “Even when an organization is taking the appropriate step of getting the data, then you actually have to use the data,” Rubin said. Building the discipline to act on what you know, in real talent discussions and real hiring choices, separates strategic organizations from those that simply collect information.

Start Where You Are

Organizations face a wide range of unknowns in the current environment. With constant change and question marks on what’s ahead, HR leaders need to act as a lighthouse, constantly assessing the horizon for changes and updating succession strategy accordingly. 

“You cannot take a one-time reading of the fog and then plan accordingly,” Reimer said. “You need to be scanning.”
