Part 4 of a 5-Part Series on the 4D Talent Continuity Framework: Develop
In the first issue of this series, I introduced my 4D Talent Continuity Framework: Design, Diagnose, Develop, Defend.
- Design ensures the system, practices, and tools are built to address real business risk.
- Diagnose reveals how exposed the organization actually is.
In case you missed it, last week’s issue focused on Diagnose, the discipline of conducting talent reviews and talent calibration that surface real succession risk rather than organizational optimism.
Once risk becomes visible, the next question is unavoidable:
What are we doing to close the gap?
That is the work of the third D: Develop.
And this is where many succession plans fail. They don’t fail because organizations lack good intentions, but because development is treated casually rather than rigorously.
Why Development Often Breaks Down
In most companies, the talent review ends with a list of successor candidates and a few vague development notes. The system assumes progress will follow. In reality, several predictable breakdowns occur.
Weak Individual Development Plans (IDPs)
Development plans often default to classroom training, online modules, or conferences. These activities may build knowledge but rarely build leadership capability.
Research on adult learning consistently shows that leaders develop primarily through experience, not instruction. The widely cited 70–20–10 model suggests that roughly 70% of leadership development comes from challenging assignments, 20% from coaching and relationships, and 10% from formal training (Lombardo & Eichinger, Center for Creative Leadership).
When IDPs emphasize the 10% and neglect the 70%, readiness does not improve.
Successor Candidates Are Never Told They Are Being Developed
Some organizations avoid informing successor candidates that they are part of the pipeline. The rationale is understandable: leaders worry about creating entitlement or promising roles that may never materialize.
The downside is significant.
When high-performing leaders do not understand that they are being invested in for larger roles, they often interpret development assignments as additional workload rather than strategic preparation. Motivation drops, and retention risk increases.
Other organizations take the opposite approach and explicitly tell successor candidates they are being prepared for future leadership roles. This can increase engagement and commitment, but it also carries risk if advancement does not materialize.
In practice, the most effective approach is transparent investment without guaranteed outcomes: communicating clearly that the organization is developing the individual for broader leadership responsibility while avoiding promises tied to specific roles.
Successor Candidates Are Already Overloaded
Another predictable failure occurs when organizations assign development on top of already unsustainable workloads.
High performers often carry the heaviest operational responsibilities. When development activities are layered onto full workloads, the message is clear:
“Grow into the next role on your own time.”
The result is predictable. Development stalls, burnout increases, and the very leaders the organization hopes to retain begin considering external opportunities.
Development That Never Leaves The Classroom
Formal training has value, but it rarely changes leadership behavior by itself.
What accelerates readiness is experiential leadership exposure:
- Cross-functional strategic projects
- Enterprise initiatives with visible impact
- Temporary leadership of unfamiliar teams
- Stretch assignments – Not impossible but challenging
- Direct coaching from senior executives
These experiences place successor candidates in situations where judgment, influence, and resilience are tested in real time.
Adults learn leadership the same way pilots learn to fly: through guided experience, not theory alone.
The Hidden Barrier: Accountability
Even when organizations design strong development plans, execution often fails because cross-functional assignments are difficult to negotiate.
The dynamic is familiar:
- The direct manager wants the successor candidate focused on current team deliverables.
- HR identifies development opportunities but lacks authority to enforce participation.
- The employee cannot realistically manage both workloads without structural support.
As a result, the most valuable development experiences never happen.
In mid-sized companies, this tension can only be resolved at the executive team level.
When development assignments are framed as enterprise investments rather than optional favors between departments, priorities change. The CEO and CHRO must signal clearly that preparing future leaders is a shared responsibility across the organization.
Without that alignment, development remains theoretical.
The Cost of Development Failure
Organizations often underestimate the financial consequences of weak development execution.
Leadership readiness gaps lead to:
- Expensive external searches for roles that could have been filled internally
- Mis-promotions when candidates are elevated before they are prepared
- Delays in strategic execution while leaders ramp into new responsibilities
Research from Gallup and Center for Creative Leadership suggests that failed leadership transitions and executive turnover can cost organizations 1.5–2 times the leader’s annual salary once search costs, lost productivity, and disruption are considered.
For senior leadership roles, the real cost can reach into the hundreds of thousands, or millions, of dollars depending on the scope of the role.
Development is not a learning activity.
It is risk mitigation.
What Rigorous Development Looks Like
Organizations that build strong leadership pipelines treat development with the same discipline they apply to strategy execution.
They:
- Create specific, time-bound development plans for successor candidates
- Ensure development includes visible, cross-functional leadership experiences
- Pair experiential learning with coaching from senior leaders
- Protect the time required for development rather than adding it as extra work
- Hold leaders accountable for developing talent beyond their own teams
When this happens, succession planning shifts from theoretical readiness to demonstrated capability.
Next week, we turn to the final discipline in the framework: Defend.
Because identifying and developing strong leaders is not enough. Organizations must also protect them from external poaching, professional burnout, and the pressures that drive high performers out the door.
Succession planning does not end with development.
It ends when leadership continuity is secure.
