Moving someone into management without preparing them to lead can affect the entire team. Research on leadership development, new manager training, management training, employee engagement, and professional coaching shows that structured development can produce measurable results.
1. Manager Training Can Increase Team Engagement by Up to 18%
Gallup reports that managers who receive training in coaching and people development can see up to 18% higher engagement among their teams. Gallup also found improvements of 20%–28% in other manager performance measures.
Why it matters: New managers need more than technical expertise. Teaching them how to coach, communicate, provide feedback, and develop employees through effective leadership development can influence the performance of the entire team.
2. Leadership Effectiveness Increased From 46% to 85% After Training
DDI's impact evaluation data found that average frontline leader effectiveness increased from 46% before leadership development to 85% after the program—a 39-percentage-point improvement.
Why it matters: Organizations shouldn't assume newly promoted managers automatically know how to lead. Structured new manager leadership training, enriched with professional coaching, can help close the gap between being a great employee and becoming an effective people leader.
3. 92% of Managers Applied Their New Leadership Skills on the Job
DDI reports that 92% of frontline managers applied new skills on the job after completing its leadership development program.
Why it matters: Effective management training programs should provide practical skills managers can immediately use for delegation, coaching, communication, accountability, conflict resolution, and difficult conversations.
4. Leadership Training Can Improve Overall Job Performance by 20%
A research summary from the Quality Improvement Center for Workforce Development reports that leadership training can produce approximately a 25% increase in learning, 28% improvement in leadership behaviors on the job, 20% improvement in overall job performance, and 25% improvement in organizational outcomes.
Why it matters: Investing in leadership development and management skills training isn't simply an employee benefit—it can translate into measurable improvements in how managers and organizations perform.
5. Managers Can Account for 70% of the Difference in Team Engagement
Gallup has found that managers account for at least 70% of the variance in employee engagement across teams.
Why it matters: Your managers have enormous influence over how employees experience your organization. Investing in new manager training, leadership communication, emotional intelligence, employee engagement, conflict resolution, and coaching skills can therefore have an impact far beyond the individual manager.
The Bottom Line
Promoting someone makes them a manager. Developing them through leadership development initiatives helps them become a leader.
Organizations that invest in new manager training and professional coaching can better equip newly promoted and emerging leaders to communicate effectively, manage conflict, coach employees, build stronger teams, improve engagement, and confidently transition from individual contributor to people leader.
