Most leadership development programs fail because they treat development as an event instead of a system. Organizations spend billions on training every year, yet 70% of HR leaders say their programs do not prepare leaders for today's challenges. As AI accelerates change, the competencies that separate effective leaders from ineffective ones become more visible and more valuable. The organizations that win will be those that intentionally measure and develop those competencies over time.
I have been brought into organizations to develop strategy, build leadership development programs, strengthen succession plans, and help leadership teams become more effective.
Whether the organization had 50 employees or 5,000, I kept seeing the same pattern.
Leaders were investing in training. They were sending people to programs. They were bringing in speakers and coaches. They were spending real time and real money developing talent.
And many of them were still quietly asking the same question.
Why is the development not sticking?
One leader grows and takes on greater responsibility. Another attends the same program and struggles to apply what they learned. One manager becomes a strong coach. Another keeps avoiding difficult conversations. One executive leads confidently through change. Another becomes overwhelmed when uncertainty rises.
The difference is rarely intelligence. It is rarely effort. More often, it comes down to capability.
That distinction has become even more important as artificial intelligence continues to reshape the workplace.
For years, organizations focused on knowledge. If people needed information, we sent them to training, handed them a book, or brought in an expert.
Today, information is everywhere.
AI can summarize articles, draft emails, create presentations, and analyze data in seconds. Knowledge has become more accessible than at any point in human history.
But knowledge is not the same as capability.
A leader can know what good coaching looks like and still struggle to coach a real employee through a real problem. A manager can read every book on accountability and still avoid the hard conversation that needs to happen Monday morning. An executive can study strategic thinking and still freeze when the business shifts unexpectedly.
The gap between knowing and doing is the gap most leadership development programs fail to close.
The World Economic Forum's Future of Jobs Report identifies analytical thinking, resilience, flexibility, leadership and social influence, creativity, motivation, and lifelong learning among the most important skills for the future workforce. Most of those are not technical skills. They are human capabilities.
Gallup's research reinforces the pattern. Manager effectiveness accounts for up to 70% of the variance in team engagement, yet most organizations promote people into management without measuring the capabilities required to lead effectively.
The signal is clear. The capabilities that determine leadership effectiveness are well-known. The question is whether organizations are actually measuring and developing them.
Most are not.
There is a difference between knowledge, skills, and competencies, and it matters more than most leaders realize.
Knowledge is what someone knows.
Skills are what someone can do.
Competencies are how consistently someone demonstrates a capability under real conditions. They are the developed ability to coach a struggling employee, navigate a difficult conversation, hold accountability without damaging the relationship, lead through ambiguity, or build trust on a team that has lost it.
Knowledge can be transferred in a workshop. Skills can be practiced in a classroom. Competencies have to be developed over time through application, feedback, and intentional growth.
That is why two leaders can attend the same training program with very different outcomes. One has the underlying competency development to apply what they learned. The other does not. The workshop did not fail. The competency gap was simply bigger than the workshop could address.
This is also why generic leadership development so often disappoints. Everyone attends the same session. Everyone reads the same book. But leadership gaps are rarely identical. One leader needs stronger conflict management. Another needs better coaching skills. Another needs strategic thinking. Another needs resilience and accountability under pressure.
Development that does not start with measurement ends up generic by default.
Capability has to be assessed before it can be developed. Otherwise, organizations are guessing.
This is where the redesigned DNA Competencies assessment from TTI Success Insights becomes powerful.
The 2026 redesign of DNA is significantly stronger than earlier versions. It includes updated factor-analysis scoring, dynamic language tailored to the individual, embedded coaching insights, and specific development actions that turn awareness into growth. This is not a personality label. It is a clear, actionable picture of where someone has developed capability and where targeted growth will create the greatest impact.

DNA measures 25 workplace competencies organized into three domains that reflect how humans are wired.
Thinking. How people process information, learn, solve problems, innovate, and make decisions. Competencies include continuous learning, problem-solving, conceptual thinking, creativity and innovation, futuristic thinking, and decision-making.
Working. How people execute, stay accountable, manage priorities, and drive results. Competencies include personal accountability, goal orientation, planning and organizing, resilience, self-starting, flexibility, project management, and customer focus.
Relating. How people build trust, influence, coach, and create alignment. Competencies include leadership, employee development and coaching, conflict management, interpersonal skills, teamwork, communication, influence, negotiation, diplomacy, and understanding others.
Most people naturally lean toward one or two of these domains. Some are thinkers. Some are deciders and doers. Some are connectors and relators. None of those wiring patterns is better or worse. The point is not to label people. The point is to understand where their developed capabilities lie and where targeted growth will create the most impact.
DNA does not work in isolation, and it should not. The most powerful insight comes when DNA is interpreted alongside other validated assessments that measure different dimensions of human performance. DISC shows how someone behaves. 12 Driving Forces shows what motivates them. Acumen Capacity Index shows how they think and make decisions under complexity. Working Genius shows where their natural energy and joy live. All of these layer into TriMetrix HD as a comprehensive picture.
Each assessment answers a question that the others cannot. Used together, they provide the clearest picture of human performance.
This is why I treat assessment data as a leadership operating system, not a hiring event. The data lives on. It supports onboarding, development, coaching, and succession decisions across the entire employee lifecycle.
AI is changing what leaders need to know. More importantly, it is changing what leaders need to become.
For most of the past two decades, organizations rewarded leaders who had the most information. Knowledge was scarce. Knowledge was power.
That equation is shifting.
AI now provides information instantly. The competitive advantage is no longer in knowing more. The competitive advantage is in what you can do with what you know.
AI cannot build trust on a team that has lost it. AI cannot coach a high-potential employee through a difficult season. AI cannot read a room during a tense leadership meeting and adjust in real time. AI cannot hold someone accountable while preserving the relationship. AI cannot help a team make sense of ambiguity when there is no clear answer.
Those are uniquely human capabilities. And they are becoming more valuable as technology becomes more powerful.
Look at the competencies DNA measures. Coaching. Influence. Conflict management. Personal accountability. Resilience. Diplomacy. Understanding others. Decision making under complexity. These are not soft skills. They are the execution skills that determine whether organizations actually deliver on their strategies.
The leaders who will thrive over the next decade will not be the ones best at using AI tools. They will be the ones who have intentionally developed the human capabilities that AI cannot replicate.
That kind of capability does not happen by accident. It has to be built.
Most organizations are not struggling to find leadership content. There are countless books, workshops, webinars, and programs available today.
The challenge is not access to information. The challenge is sustainable behavior change.
I have seen organizations invest heavily in leadership development only to find that six months later, many leaders have returned to old habits. According to Gartner, 70% of HR leaders report that their leadership development programs fail to prepare leaders for current challenges. That is not a content problem. That is a system problem.
Research on behavior change is clear. People do not change because they attended a workshop. They change because new behaviors become part of how they work every day. That requires ongoing practice, accountability, reflection, reinforcement, and coaching.
This is where competency development becomes especially important.
When leaders understand the specific capabilities they need to strengthen, development becomes focused. Instead of trying to improve everything at once, they intentionally build the competencies that will have the greatest impact on their effectiveness.
One more thing matters here. We often measure the leader but forget to measure the environment the leader creates.
Employees consistently tell us what they need from the workplace. People want clarity, recognition, growth, connection, support, and the opportunity to contribute. They want to feel safe, seen, successful, and supported.
None of those conditions happen by accident. They are created by leaders.
Which means leadership development is not simply about helping an individual become more effective. It is about developing leaders who create the conditions in which others thrive.
If leadership development is going to actually change behavior, it has to be designed as a system, not delivered as an event.
I think about this work through three lenses, because real leadership development has to land at the level of the person, the outcome, and the system.
The first lens is the person.
This is about the leader sitting across from you. The manager who has been promoted three times and has never been trained. The director, who is technically strong but struggles with conflict. The high-potential candidate is ready for the next role, with gaps that no one has clearly named. When competencies are measured and named, leaders feel seen. They understand what they bring, what they need to grow, and how that growth will help them lead more effectively. Development becomes personal, not generic.
The second lens is the outcome.
The business case is overwhelming. The Gallup State of the Global Workplace 2026 report shows global employee engagement fell to 20% in 2025, the lowest level since 2020. Manager engagement has dropped nine points since 2022. Less than half of managers globally have received any management training, and trained managers are half as likely to be actively disengaged. The economic cost of disengagement is now estimated at over $10 trillion globally. This is not a soft issue. It is a profit issue, a retention issue, and a strategy execution issue.
The third lens is the system.
This is the lens most organizations skip. According to the DGFP Future Skills Radar 2026, 96% of companies have not integrated future skills into everyday work. They have programs. They have workshops. They have content. What they do not have is a designed system that measures capability, develops it intentionally over time, reinforces it through coaching and feedback, and aligns the rest of the organization to reward the new behaviors. Without that system, the workshop ends, and the old environment pulls people back to old habits. With that system, development compounds. Behaviors become normal. Culture shifts.
This is what Development by Design means.
It means defining the competencies that matter for your specific organization and your specific culture. Measuring where your leaders currently stand. Building development plans individualized to each leader's strengths and gaps. Embedding practice, accountability, and coaching into how the organization operates day to day. Speaking the language of your business. Aligning leadership development with strategy, performance management, and succession planning so the whole system pulls in the same direction.
This is not a workshop. This is not a program. This is a system designed to develop human capability at the speed and scale the next decade will require.
The redesigned DNA assessment is one of the most powerful starting points for this work. It gives leaders specific, measurable language for the 25 competencies that determine effectiveness. It identifies which capabilities are developed and which need intentional growth.

DNA is one piece of the puzzle. It pairs powerfully with the other multi-science assessments your organization may already use. Some organizations start with DNA alone for targeted competency development. Others combine DNA with behavior and motivators in TriMetrix DNA. The most comprehensive picture comes from TriMetrix HD, which integrates behavior, motivators, competencies, and acumen into a single integrated view. The right entry point depends on the specific challenge you are trying to solve.
This is the conversation worth having.
AI will continue to reshape work. The competencies that determine leadership effectiveness are not going to be automated away. They will become more valuable as technology grows more powerful.
Organizations that win the next decade will not be the ones with the best AI tools. They will be the ones with leaders who have intentionally developed the human capabilities AI cannot replace. Coaching. Accountability. Judgment. Influence. Adaptability. Conflict management. Trust. Decision-making under pressure.
Those capabilities have to be developed. They will not appear by accident.
That is what Development by Design is built to do.
