CEOs and People & Culture leaders often grapple with how to develop effective leaders in their organisations. Through his extensive research, David Day challenges traditional approaches to leadership development and offers evidence-based insights that can revolutionise how organisations approach this critical function.
David Day is a prominent leadership scholar who serves as Professor of Psychological Science and Academic Director of the Kravis Leadership Institute at Claremont McKenna College. His 2024 book “Developing Leaders and Leadership: Principles, Practices, and Processes” offers an evidence-based examination of how both individuals and collectives develop their capacity for leadership, distinguishing itself from other works by focusing on the scientific principles and developmental processes rather than just leadership programs or techniques.
The Fundamental Difference: Leader vs Leadership Development
Five First Principles of Development
1. You Cannot Make Anyone Develop as a Leader
Development requires personal ownership and agency. HR professionals can create the conditions for development and provide resources, but ultimately, each individual must choose to engage in their own development journey. This means moving away from mandatory development programmes and towards creating compelling opportunities for growth that individuals actively choose to pursue.
2. Development Requires Dedicated Work Over a Long Period
Just as someone wouldn’t expect to become physically fit after a single gym session, organisations can’t expect leadership capability to develop through one-off workshops or training sessions. Real development requires consistent practice and application over months and years. This challenges organisations to move beyond the ‘event-based’ approach to leadership development and create sustained development pathways.
3. Leadership is Learned Through Experience
Day provocatively suggests that the everyday work environment is a leadership development gym. Rather than relying solely on formal training programmes, organisations need to help their people recognise and leverage the developmental opportunities in their daily work experiences. This might involve structuring work assignments to provide growth opportunities or helping people reflect on and learn from their everyday leadership challenges.
4. Meaningful Developmental Experiences Include Assessment, Challenge, and Support
5. There are Evidence-Based Practices that Support Development

Proximal and Distal Outcomes
Individual Proximal (Short-term) Outcomes
Collective Proximal Outcomes
At the collective level, proximal indicators emerge as collective emergent states:
- Psychological safety develops as a shared belief that interpersonal risk-taking within the group won’t result in harm
- Shared mental models evolve about how leadership should be enacted when facing complex adaptive challenges
- Collective leadership efficacy grows as the group develops confidence in its shared ability to execute leadership actions
- Collective leadership identification strengthens as members begin to see leadership as a shared process rather than individual responsibility
Collective Distal Outcomes
The long-term collective outcomes represent sophisticated capabilities that emerge through intensive interpersonal interactions over time:
- Macrocognition develops as a form of externalized cognition that emerges through intensive interpersonal interactions grounded in shared mental models
- Dynamic capabilities evolve, enabling the collective to adapt its leadership approach based on different situations and challenges
- Collective requisite complexity emerges, allowing the group to match its level of complexity to the specific adaptive challenge at hand
- The ability to reconfigure network structures develops, enabling the collective to adopt centralized, decentralized, or distributed leadership patterns as needed
Developing Collective Leadership Capacity
Creating broader leadership capacity across the organisation requires attention to both collective states and network development.
Collective Emergent States
- These are the shared conditions that enable collective leadership:
- Psychological safety allows people to take interpersonal risks
- Shared mental models help groups understand leadership challenges similarly
- Collective leadership efficacy builds confidence in the group’s leadership capability
- Collective identification helps people see themselves as part of a leadership community
Social Network Development
Practical Implications for HR Leaders
Based on Day’s research, here are key recommendations for practice:
Design Development Systems, Not Just Programmes
Move beyond the traditional approach of sending people to leadership training. Instead, create comprehensive systems that support ongoing development through multiple channels and experiences. This includes building regular feedback mechanisms and creating opportunities for practice and reflection.
Focus on Both Individual and Collective Development
Leverage Experience Intentionally
Take a Long-term View
Conclusion
For HR and People & Culture leaders, Day’s research offers a blueprint for transforming leadership development in their organisations. By moving beyond traditional programme-based approaches to create comprehensive development systems, organisations can better support both individual and collective leadership growth.
The key is recognising that leadership development isn’t about quick fixes or one-size-fits-all solutions. Instead, it requires a systematic, long-term approach that addresses both individual and collective development needs while remaining grounded in research evidence.
As organisations face increasingly complex challenges, this evidence-based approach to leadership development becomes ever more critical. By applying these principles, organisations can create more effective leadership development initiatives that produce lasting results.
I offer the Ways of Working Team Coaching Programme that embodies the principles we’ve discussed and offers a practical roadmap for People & Culture leaders looking to transform their organisations’ approach to leadership development. I work with my colleague Alyson Keller from Performance Impact to deliver the programme. You can read about this programme on my blog: Unlocking Team Potential.
If you’re interested in exploring how utilising these principles might support your organisation’s leader and leadership development system, I’d welcome a conversation.
