Succession Planning: What It Is, Why It Matters, and Where to Start 

Leadership transitions are inevitable. Whether a key employee retires, accepts a new opportunity, or leaves unexpectedly, organizations that aren’t prepared often find themselves reacting under pressure. 

That’s where succession planning comes in. 

Succession planning isn’t just for large organizations or executives nearing retirement. It’s a strategic process that helps organizations prepare for leadership transitions, organizational growth, and unexpected change by developing future leaders before they’re needed. 

To provide additional perspective throughout this article, we invited Peter Demangos, CEO and Co-Founder of SuccessionHR, to share his insights on effective succession planning and leadership continuity. 

Whether you’re beginning to think about succession planning or wondering if your organization is ready to formalize the process, this article explores what succession planning is, why it matters, and what organizations should consider before getting started.  

What Is Succession Planning? 

Succession planning is the process of identifying critical roles within an organization and preparing employees to step into those positions when leadership transitions occur. 

Unlike replacement planning, which focuses on finding someone to fill a vacancy after it arises, succession planning takes a longer-term view. It emphasizes developing leadership capability and strengthening leadership readiness over time so organizations can maintain continuity when change inevitably happens. 

“A lot of organizations tend to look at readiness as a yes-or-no decision. In reality, readiness exists on a continuum. The better question isn’t, ‘Is this person ready?’ It’s, ‘What’s standing between where they are today and where they need to be?’ That creates a much more productive conversation because it naturally leads to development instead of debate. Succession planning shouldn’t be about selecting successors from a list. It should involve intentionally building leadership readiness over time. When it’s approached this way, development tends to become proactive instead of reactive.” 

It’s also important to distinguish succession planning from workforce planning or organizational planning.  

While workforce planning helps organizations determine the people and skills they’ll need to achieve future business goals, and organizational planning focuses on structure and reporting relationships, succession planning answers a different question: If a critical leader left tomorrow, would we be prepared? 

As Peter explains, succession planning is fundamentally about protecting leadership continuity rather than simply documenting organizational structures. Workforce planning helps organizations understand how the business is built, while succession planning helps organizations prepare for leadership change within that structure.  

“I think one of the biggest misconceptions is that succession planning starts and ends with a document or a spreadsheet. Too often, organizations identify successors once a year, file the plan away, and revisit it the following year. In reality, succession planning is an ongoing process. Leadership readiness changes constantly, so organizations need to be continuously developing future leaders if they want to strengthen leadership continuity.” 

Why Succession Planning Matters 

Succession planning is often associated with preparing for retirement, but its value extends far beyond planned leadership transitions. 

Organizations that invest in succession planning are often better positioned to: 

• maintain business continuity during unexpected change 

• preserve institutional knowledge 

• reduce disruption when critical roles become vacant 

• strengthen employee development and internal mobility 

• support long-term organizational growth 

Rather than reacting to change, succession planning gives organizations greater confidence that leadership capability can continue to evolve alongside the business. 

“In most organizations, succession planning starts as a risk management conversation. Executives and boards want line of sight into leadership risk and business continuity. From there, HR is responsible for bringing structure to the process, creating consistency, and helping the organization turn that strategy into action.  

But while succession planning absolutely requires HR leadership, it can’t succeed as an HR-only initiative. The people best positioned to identify, develop, and prepare future leaders are those closest to the role itself (the Key Role Owners). HR provides the framework, visibility, and consistency, but accountability for developing future leaders needs to sit with the people who understand the role best. That’s when succession planning shifts from being an annual HR exercise to a business strategy that strengthens leadership continuity across the organization.” 

What Should Organizations Consider Before Starting a Succession Plan? 

One of the biggest misconceptions about succession planning is that it begins by identifying successors. 

In reality, organizations often see the greatest success when a few foundational elements are already in place. 

1. Leadership alignment: Succession planning shouldn’t be owned by HR alone. Executive leaders should understand why succession planning matters and be committed to supporting long-term leadership continuity. 

2. Strong HR foundations: Clear job descriptions, meaningful performance conversations, leadership competencies, and career development practices all create a stronger foundation for succession planning. 

3. Manager capability: Managers play an important role in identifying potential, supporting employee development, and having regular career conversations. Organizations where these practices already exist are often better positioned to build sustainable succession plans. 

“The organizations that sustain succession planning really do two things well. First, they establish clear ownership. There’s someone who knows each critical role inside and out and is responsible for making sure there’s someone ready to step into that role in the future. Second, they create accountability by regularly tracking whether people are actually becoming more ready over time. Those two habits keep succession planning active instead of letting it sit on a shelf.” 

What Makes a Succession Plan Effective? 

Creating a succession plan is only the beginning. To remain effective, succession planning should evolve alongside the organization. 

Strong succession planning is supported by: 

• regular talent and development conversations 

• leadership accountability 

• objective decision-making 

• alignment with changing business priorities 

• ongoing employee development 

Rather than becoming a document that’s reviewed once a year, succession planning should become part of how organizations think about leadership development over time. 

When Is the Right Time to Start a Succession Plan? 

Many organizations assume succession planning can wait until someone announces their retirement. 

In reality, the best time to start is before leadership transitions become urgent. 

You may be ready to begin if: 

• your organization is experiencing growth 

• key leaders are approaching retirement 

• you’re expanding into new markets or locations 

• internal promotions are becoming more common 

• critical knowledge sits with only a few individuals 

Starting early gives organizations more time to develop future leaders intentionally rather than responding reactively. 

“From my perspective, the organizations that do succession planning well stop treating it as a response to change and start treating it as part of how they build the business. They don’t wait for a retirement, resignation, or promotion to start thinking about future leaders.  

Instead, they create a culture where people take ownership of the roles they’re in, understanding they have a responsibility not just to perform in the role today, but to help prepare the person who could one day step into it. HR plays an important role in enabling that culture, but it has to be embraced across the organization. They recognize that every key role will eventually become vacant, so they’re continuously developing people and strengthening leadership readiness long before they need it.” 

Succession Planning Is Stronger When Strategy and Structure Work Together 

Effective succession planning doesn’t happen in isolation. It combines thoughtful people strategies with structured planning, helping organizations prepare not only for leadership transitions but also for long-term organizational resilience. 

Building future leaders requires more than identifying names on a list. It involves creating an environment where employees can grow, managers are equipped to support development, and leadership continuity becomes part of broader business planning. 

When organizations bring these elements together, succession planning becomes an ongoing investment in future capability rather than a response to unexpected change. Developing these people strategies requires ongoing alignment between business goals, leadership development, and HR practices.
