How to Evaluate Successor Pool Depth and Diversity

Provides a framework to analyze the sufficiency and representativeness of successor pipelines across levels and functions.

 

Introduction

Succession planning is essential for organizations to ensure leadership continuity and organizational stability. However, to effectively future-proof an organization, it’s crucial not only to focus on identifying successors but also to assess whether the successor pool is deep enough and diverse enough to meet the future needs of the business.

A strong successor pool ensures that the organization has viable options across all levels and functions, ready to step into key roles as needed. Furthermore, it’s essential to ensure diversity in the successor pipeline to foster inclusivity, bring varied perspectives, and ensure leadership reflects the broader organizational makeup. This guide provides a structured approach for evaluating the depth and diversity of your successor pool.

 

Step 1: Define the Criteria for Successor Pool Depth

The depth of the successor pool refers to the number of potential successors identified for key roles within the organization, as well as the readiness of those successors. HR leaders need to assess whether the pool contains enough candidates at various stages of readiness to ensure smooth transitions when key roles become vacant.

 

1.1 Assessing Number of Successors per Role

Each critical role within the organization should have multiple successors identified. The depth of the pool is not just about having a single successor for each role; rather, it’s about having several potential candidates who can step into these roles as they become available.

  • High-Level Roles: Executive and senior leadership roles may need 2-3 potential successors identified, considering the complexity and long ramp-up times.
  • Mid-Level Roles: For department heads or key operational leaders, 3-4 potential successors may be necessary.
  • Specialized Roles: For technical or highly specialized positions, consider a minimum of 2 candidates who are highly trained or capable of rapidly learning the required skills.

 

1.2 Assessing Successor Readiness

Readiness is a key measure of the successor pool's depth. HR leaders should assess not only the number of successors but also their development stage. Successors should be ready at varying levels, from those who need just a short transition period to those who are a few years away from stepping into the role.

  • High Readiness: Successors who are ready to step into the role immediately or within 6 months.
  • Medium Readiness: Successors who are 1-2 years away from being ready.
  • Low Readiness: Successors who require 3+ years of development and experience before taking on the role.

 

Example:
For a Chief Marketing Officer (CMO) role, a successor who is currently a Vice President of Marketing may be ready for promotion within the next 12 months. Another potential successor, who is a Director of Marketing in a different region, may be 2-3 years away from taking on the CMO position due to the need for more cross-functional experience.

 

Step 2: Evaluate Successor Pool Diversity

While depth is crucial, diversity is equally important in building a resilient and inclusive leadership pipeline. A diverse successor pool brings different perspectives, better decision-making, and a broader range of skills to the organization. HR leaders need to ensure that diversity considerations are built into the successor pipeline evaluation.

2.1 Assessing Demographic Diversity

Ensure that the successor pool reflects a diverse mix of candidates in terms of demographic factors like:

  • Gender: A balance between male and female successors to foster gender equality.
  • Race/Ethnicity: A mix of racial and ethnic backgrounds that mirrors the diversity goals of the organization.
  • Age: Consider including successors from various age groups to ensure both short-term and long-term leadership sustainability.

 

2.2 Assessing Functional and Cognitive Diversity

In addition to demographic diversity, it’s critical to look at the functional diversity and cognitive diversity of the successor pool:

  • Functional Diversity: Ensure the pool includes successors from various functional areas (e.g., operations, finance, sales, marketing, HR) to provide leadership from different parts of the business.
  • Cognitive Diversity: The successor pool should represent different thinking styles, problem-solving approaches, and decision-making frameworks. This diversity enriches leadership discussions and ensures the organization can adapt to complex challenges.

 

2.3 Aligning with Organizational Diversity Goals

If the organization has set specific diversity and inclusion goals, ensure that the succession plan aligns with these objectives. For example, if a company has committed to increasing the representation of women in leadership, the successor pool should reflect that commitment.

 

Example:
A global tech company with a strong diversity initiative might target increasing the number of women in senior technical roles. To support this, HR should assess whether the successor pool includes women in leadership roles, such as VP of Engineering or CTO, and ensure that these women have the development opportunities needed to advance.

 

Step 3: Analyze Succession Pool Adequacy Across Organizational Levels and Functions

A well-rounded successor pool should span across various levels and departments within the organization. It’s essential to ensure that key roles at every level have adequate and diverse representation in the successor pool, avoiding any potential gaps that could lead to leadership vacuums.

 

3.1 Successor Representation Across Levels

Organizations should have a multi-tiered approach to succession planning:

  • Top Leadership (C-suite): 2-3 successors for each top executive role.
  • Middle Management (Director/VP): A larger pool, with 4-5 successors identified for each critical middle management position.
  • Entry-Level and Specialized Roles: Ensure that these roles also have successors identified, especially for mission-critical or technical roles.

Example:
For a global HR director role, the successor pool might include candidates from both the US and EMEA regions, ensuring that there’s sufficient geographic diversity and understanding of the organization’s global operations.

 

3.2 Succession Pool Representation Across Functions

It’s essential to consider the functional diversity within the successor pool. Key leadership roles in different departments should have a well-balanced number of successors identified:

  • Cross-Functional Representation: Make sure that the successor pool spans the major functions within the business (e.g., sales, finance, operations, marketing, technology, HR).
  • Cross-Department Mobility: Identify successors who can transition between departments, especially for leadership roles that require broad organizational knowledge.

 

Example:
For a Chief Financial Officer (CFO) role, HR leaders might look to a successor from within the finance function (e.g., a VP of Finance) but should also consider successors from operations or strategy roles who can bring a fresh perspective on financial leadership.

 

Step 4: Use Data and Analytics to Assess Successor Pool Sufficiency

To ensure a data-driven approach, HR professionals should leverage analytics tools and people data to assess the adequacy of the successor pool.

 

4.1 Quantitative Analysis of Successor Pipeline

Use data from performance reviews, development programs, and talent assessments to evaluate the readiness of successors. Metrics to track include:

  • Number of Successors per Role: Ensure that each critical role has at least 2-3 successors identified.
  • Development Plans in Place: Measure how many successors have clearly defined development plans that include targeted training, mentorship, and cross-functional experience.
  • Readiness Levels: Track the proportion of successors categorized as ready, developing, or needing more time to ensure the depth of the pool.

 

4.2 Qualitative Assessment of Leadership Potential

In addition to quantitative data, conduct talent reviews and leadership assessments to ensure that successors have the right leadership potential and skills for future roles. This can include:

  • Leadership Bench Strength: Regular evaluations of leadership potential, which may involve a combination of 360-degree feedback, performance reviews, and psychometric assessments.
  • Cultural Fit: Assess the alignment of successors with organizational values and the ability to navigate cultural shifts or challenges.

 

Step 5: Implement Ongoing Monitoring and Adjustments

Succession planning is a dynamic process that requires continual monitoring and adjustments. HR leaders should not only evaluate the successor pool once but should implement regular reviews to ensure the depth and diversity of the pool are consistently maintained and updated.

  • Annual Review: Assess the successor pool depth and diversity on an annual basis to identify gaps, new talent, or emerging leaders.
  • Quarterly Check-ins: Have quarterly discussions with key stakeholders (e.g., senior leaders, department heads) to review the progress and readiness of successors.
  • Talent Mobility: Track the movement of talent across roles, ensuring that successors gain exposure to critical leadership experiences and broad organizational knowledge.

 

Conclusion

Evaluating the depth and diversity of your successor pool is critical to ensuring that the organization is ready for the future. A diverse and deep successor pool not only supports leadership continuity but also ensures that the organization can adapt to new challenges, foster innovation, and reflect the values of inclusivity. By using both qualitative and quantitative data, HR leaders can proactively manage the succession pipeline to mitigate potential leadership gaps and ensure that future leaders are equipped with the skills, experiences, and diverse perspectives necessary for success.
