Most organisations invest in development without a clear framework for deciding who gets what. Training budgets are allocated based on seniority, availability, or whoever asks loudest. The result is a lot of activity and very little measurable change.
Effective talent development starts with a different question. Not 'what training do we offer?' but 'who do we need to develop, for what purpose, and what will it take to get them there?'
The development ROI problem
Only 12% of employees apply new skills learned in L&D programs to their jobs (McKinsey). The gap between training activity and behaviour change is not a training quality problem - it is a targeting and follow-through problem.
Who to invest in
Not all development investment delivers the same return. The highest-return development investments are those made in people who are in or preparing for High-Impact Positions - the roles where the quality of the person has a direct, measurable effect on business outcomes.
Within that group, the most valuable investments are those that close a specific, identified gap between where someone is now and where the business needs them to be. Generic development programmes have their place, but targeted development - designed around a specific person, a specific role, and a specific gap - consistently delivers better outcomes.
Segmenting your development investment
**High-impact roles, high-readiness people** Focus on accelerating readiness. These individuals are close to the target role and need specific, targeted development to close the remaining gap. Stretch assignments, mentoring, and targeted coaching deliver the best return here.
**High-impact roles, lower-readiness people** Focus on building foundational capability. These individuals have potential but need more structured development over a longer timeline. Formal learning, cross-functional exposure, and regular feedback are most effective.
What to invest in
The most effective development investments are those that address the specific gap between a person's current capability and the requirements of their target role. This requires a clear understanding of both the current state and the future state.
Development interventions fall into three broad categories: formal learning (courses, certifications, structured programmes), experiential learning (stretch assignments, job rotations, project leadership), and social learning (mentoring, coaching, peer learning). The research consistently shows that experiential learning delivers the highest transfer to on-the-job behaviour - yet most development budgets are skewed heavily towards formal learning.
How to measure return on development investment
Development ROI is notoriously difficult to measure, but that does not mean it should not be measured. The organisations that get the most from their development investment are those that define success upfront - before the development starts.
For each significant development investment, define: what behaviour change is expected, how it will be observed, and what business outcome it is expected to support. Review this at 30, 60, and 90 days post-development. This is not about bureaucracy - it is about accountability and learning.
Building the system
Individual development decisions are only as good as the system that supports them. A sustainable talent development system requires quality data on performance and potential, a clear framework for identifying development priorities, processes for creating and tracking development plans, and manager capability to have meaningful development conversations.
Without this infrastructure, development investment remains reactive and disconnected from business outcomes.
