Summary:
Leadership science is the foundation of effective leadership development. By understanding what makes leaders effective, how leadership behaviors change, and how better leadership impacts business performance, organizations can make more informed decisions about developing their leaders.
Why Does Leadership Effectiveness Start With Science?
Building leadership effectiveness requires more than intuition. Every investment in development needs to translate into more effective leadership behaviors and business results. You need evidence to focus your investment where it will have the greatest impact.
Which capabilities matter most? How do leaders develop them? How will those changes influence performance?
That’s where leadership science comes in.
As leadership trends rise and fade by the day, and AI-generated content floods the market with new ideas, separating evidence from opinion has never been more important. Leadership science gives you the confidence that your leadership development strategy is grounded in what’s proven to work—not the latest fad.
DDI’s leadership science informs every solution, innovation, and assessment we create. And it continues to evolve alongside the changing realities leaders face. Our I/O psychologists, consultants, and R&D teams draw on decades of leadership research, assessment insights, and business impact measurement to help organizations make smarter decisions about developing effective leaders. It brings together three connected disciplines:
- Leadership Research identifies the capabilities and behaviors leaders need to succeed today and tomorrow.
- Leadership Behavior Science explains how leaders develop lasting behavior change.
- Business Impact Measurement connects better leadership to measurable business results.
Leadership Research: An Ongoing Study of the State of Leadership
What do today’s leaders need?
Leadership expectations don’t stand still. Shifting markets, new technologies, workforce changes, and evolving business priorities continuously reshape what effective leadership looks like. To keep your leadership development relevant, you need evidence that helps you understand today’s realities.
DDI’s research uncovers what pressures and changes are shaping leadership today so organizations can prepare their leaders for what’s next.
What the Research Tells Us
- Uncertainty is leaders’ biggest business challenge. 1 in 3 executives identified navigating uncertainty as their organization’s top business challenge for the next three years.1
- Leaders are struggling to stay ahead of change. Only 1 in 5 leaders say they learn about important issues as early as they should, while 70% of managers feel overwhelmed by the lack of information they receive.1
- Leadership development is falling behind future needs. 83% of HR organizations expect the need for new leadership capabilities to increase within the next five years. Yet major gaps remain between the skills leaders consider critical and the development they receive.2
- Most organizations are not confident in their leadership pipeline. Only 20% of HR professionals feel confident in their organization’s leadership bench. That leaves 80% uncertain that they have the leaders they need for the future.2
- Development can strengthen leaders’ connection to their organization. Participants who feel valued as a result of their development experience are 21x more likely to feel engaged as leaders.3
How DDI Studies Leadership Research
Improving leadership effectiveness starts with knowing the context your leaders operate in—and the capabilities that help them succeed.
DDI studies leadership from multiple perspectives to make sure our research reflects the insights you need. We combine global research studies, assessment insights, client feedback and results, workplace trends, and ongoing analysis of emerging business challenges to continuously refine how we understand effective leadership.
At the center of this work is our Global Leadership Forecast, the world’s largest leadership study of its kind. It helps organizations benchmark their leaders, anticipate emerging challenges, and make evidence-based decisions about their leadership development.
These insights shape how DDI identifies the capabilities leaders need today—and anticipates what they'll need tomorrow.

What the Research Tells Us
The Science Behind Leadership Behavior
What actually helps leaders change their behavior?
Organizations invest in leadership development to execute strategy, navigate change, and improve business performance. But those outcomes depend on leaders applying new behaviors every day on the job. Without lasting behavior change, even the strongest strategies and programs struggle to deliver results.
That's why DDI studies the science of behavior change. We research how leaders learn, practice, receive feedback, build habits, and sustain new behaviors over time. These insights help us design every development experience to move beyond knowledge transfer and create meaningful change at work.
-
Leaders can—and do—improve.
Across DDI programs, leaders increased their effective leadership behaviors by an average of 40%.3
-
Practice increases the likelihood that leaders will apply new skills.
Leaders who had opportunities to practice during development were: 19x more likely to feel motivated to apply new skills. 11x more likely to feel engaged as leaders. 8x more likely to see a future for themselves within their organization.3
-
Relevant development, motivation, and manager support drive behavior change.
Across 55+ years of DDI research, leaders consistently identified job relevance, personal motivation, and manager support as the three strongest predictors of applying new skills on the job.3,4
-
Developing leaders earlier creates greater gains.
Effective leadership behaviors increased by: 77% among informal and emerging leaders 75% among frontline leaders 56% among mid-level leaders 40% among senior leaders.3
-
It’s never too late to become a more effective leader.
When development was adapted to their experience and needs, senior leaders reduced ineffective leadership behaviors by 74%.3
How DDI Studies Leadership Behavior Change
Behavior change isn't accidental. Many of the principles behind it—practice, feedback, coaching, reinforcement, and motivation—have been supported by research for decades. DDI continually tests and improves how those principles evolve along with the changing realities leaders face. We do this by measuring the impact of leadership development programs with our clients, including changes in leader behavior.
These insights shape every leadership experience we design. The result is development built to help leaders practice new skills, apply them on the job, and sustain more effective behaviors over time.
Measuring the Impact of Better Leaders on Business Outcomes
What happens to business performance when leaders do change?
Leadership development isn't valuable because people complete a program. It's valuable because leaders behave differently afterward—and the business performs better as a result.
That's why DDI measures the impact of leadership development beyond participation rates and learner satisfaction. Our business impact research connects leadership capabilities to outcomes such as employee engagement, retention, productivity, and financial performance. Measuring those outcomes helps organizations demonstrate that leadership development is a strategic business investment—not simply a learning initiative.
What the Research Tells Us
How DDI Measures Business Impact
DDI combines multiple sources of evidence to help organizations understand the value of their investment and make smarter decisions about future development.
We analyze findings from the Global Leadership Forecast to identify the leadership capabilities and development practices associated with top-performing organizations. We also partner with independent analysts and conduct ongoing impact studies with our clients to measure outcomes ranging from employee retention and productivity to customer satisfaction and financial performance.
These insights help organizations execute business strategy, achieve financial goals, continuously improve leaders, and demonstrate the value of leadership development to stakeholders.
Better leaders produce better business results—and leadership development isn’t complete until its impact is measured.
-
Leadership development delivers measurable business outcomes.
We’ve seen it first-hand with our clients: $20 million in savings from reduced turnover 60% fewer workplace accidents 114% higher sales 71% higher customer satisfaction after developing their leaders.
-
Effective coaching improves team productivity.
Employees who rate their leaders as effective coaches are 16x more likely to say their leader improves their team's productivity.3
-
Organizations that invest in leadership outperform their peers.
Companies that provide effective leadership development at every level are 2.7x more likely to be top financial performers in their industry.2
-
Leadership quality impacts organizations’ ability to achieve financial goals.
When leader quality is very good or excellent, organizations are 1.7X more likely to be among the top 10% of financial performers.1
