Why Succession Planning Can’t Wait Until Someone Leaves

How do leaders ensure continuity when a key leader suddenly exits? 

The short answer is: 

Succession planning shouldn’t be viewed as a contingency plan. It should be a core leadership responsibility that protects performance, culture, and momentum long before a role becomes vacant.  

Too often, succession planning is treated as something to address after a resignation, retirement, or unexpected disruption. By then, organizations are already reacting under pressure. The strongest leadership teams take a different approach: they build leadership continuity intentionally, over time, and with clear ownership.

At Robertson Lowstuter, we see succession planning not as a document or a list of names but as a living leadership system grounded in development, mentoring, and strategic foresight.

Why Succession Planning Matters More Than Ever 

Leadership transitions rarely happen in a vacuum. When succession planning is delayed, organizations often experience: 

• Decision paralysis 

• Loss of institutional knowledge 

• Declining engagement and trust 

• Slowed execution during periods of change
  

Succession planning protects more than titles. It safeguards culture continuity, preserves strategic direction, and ensures leaders at every level are prepared to step forward with confidence.

In fast-moving organizations, waiting until someone leaves is already too late.

Common Misconceptions About Succession Planning 

Many leaders hesitate to act because of a few persistent myths: 

• “Succession planning is only for executives.” 
  In reality, leadership gaps at any level can disrupt performance. 

• “It means naming a replacement too early.” 
  Effective succession planning focuses on readiness, not rigid role assignments. 

• “Talking about succession means we expect someone to leave.” 
  Strong leaders develop others precisely because they’re committed to long-term success.
  

Reframing succession planning as leadership stewardship changes the conversation entirely.

What Proactive Succession Planning Actually Looks Like 

Succession planning works best when it’s embedded into how leaders lead, not handled as an annual HR exercise.

Step-by-Step: Building Leadership Continuity 

1. Identify critical leadership roles 
Focus on roles that carry decision-making authority, cultural influence, or operational risk.

2. Assess leadership capacity NOT just performance 
Potential is about learning agility, judgment, and adaptability, not tenure. 

3. Create intentional development paths 
Stretch assignments, coaching, and feedback accelerate readiness.

4. Formalize mentor/mentee relationships 
Mentorship transfers institutional knowledge and leadership judgment in ways training alone cannot. 

5. Revisit and refine regularly 
Succession planning evolves as people, strategy, and business needs change.

Why Mentor/Mentee Programs Strengthen Succession Plans 

Mentorship is often the missing link between identifying future leaders and actually preparing them.

Well-designed mentor/mentee programs: 

• Accelerate leadership readiness 

• Reinforce organizational values 

• Build confidence and decision-making capability 

• Reduce risk during leadership transitions
  

Instead of scrambling to replace experience, organizations grow it internally.

What to Measure in Succession Planning 

To keep succession planning actionable, leaders should track: 

• Bench strength for critical roles 

• Leadership readiness timelines 

• Internal promotion rates 

• Engagement and retention among high-potential leaders 

• Effectiveness of mentor/mentee relationships
  

These indicators reveal whether succession planning is working or quietly eroding.

Tools and Roles That Support Succession Planning 

Succession planning is most effective when shared across leadership: 

• Executives set direction and model development 

• Managers identify and coach emerging leaders 

• Mentors transfer knowledge and perspective 

• External leadership partners provide objective assessment and structure
  

An experienced leadership partner can help organizations move from intention to execution without overcomplicating the process.
