Leadership Development

The Leadership Development Gap
Between Knowing and Doing.

What a former Deloitte Managing Director learned about turning leadership potential into lasting behavioral change.

Terry Patterson still remembers watching an engineer walk down a corridor at Ford.

The man was, in Patterson's words, "an absolutely brilliant automotive engineer," and that brilliance had carried him quickly through the ranks. It had not made him a good manager. He struggled to relate to the people who worked for him, and it was pointed out to him more than once, in settings Patterson describes as uncomfortable.

Patterson saw what followed as a colleague, from inside the company. Over eight to ten years, the engineer made a concerted effort to build the human side of leadership alongside the technical mastery he already had. Eventually he could walk the halls of his engineering building and greet every person by name, knowing something of their story and their family. Patterson calls him "literally one of the best leaders that I had ever worked with."

The story is memorable because of the hallway. It is instructive because of the timeline.

The same rules at every scale

Patterson has seen leadership development from several vantage points: as an HR executive at Ford, inside IBM, and for roughly fifteen years as a Managing Director in Human Capital Consulting at Deloitte, advising organizations of the same caliber. Today many of the executives he coaches run small and mid-sized businesses. One might expect the lessons not to travel. He finds the opposite. Leadership growth comes down to high performance, lifelong learning and continued career growth.

"Those three things apply no matter what type of organization that you work in."

If the fundamentals hold across industries and sizes, the variable that matters is execution: whether development actually reaches the work.

Where the investment leaks

Patterson values formal development. Training, leadership programs and executive MBAs are "really, really valuable interventions," and the right tool for specific skills and knowledge. The mistake is relying on them alone. They arrive infrequently, many people have no personal development plan they are continually working on, and learning fades before it meets a real decision.

"Ongoing, repetitive, week in, week out work with your manager, with your coach, with whoever it is, tends to have far more positive impact than occasional training programs." Combined with that ongoing work, he says, "that's when it becomes really powerful."

From learning to leadership performance

1

Focus

Choose a very small number of capabilities that matter most, rather than the whole list.

2

Apply

Practice them in real meetings, presentations, decisions and conversations, with a plan for each.

3

Evaluate

Look for evidence of changed behavior and performance over time.

A framework synthesized by Viveka's editors from Terry Patterson's interview, not a named methodology of his.

Patterson's own coaching works this way. He starts from core leadership capabilities, narrows to the few a leader most needs, and ends every session with an assignment drawn from the leader's actual calendar. The learning, he says, "becomes not an academic exercise, but something that is real world focused."

Evaluation is where his perspective is most useful to talent leaders. He draws on instruments such as Hogan, MBTI, DiSC and 360 reviews for data points over time, but gives qualitative evidence equal or greater weight: a conversation among the leader, their executive sponsor and the coach about how the leader handles a specific kind of situation now, compared with six months ago. He accepts the subjectivity. "That's always going to be there." The clearest signal comes from the leader: "18 months ago, I wouldn't have approached this situation in this particular way."

No ceiling

The standard applies at the top. Patterson rejects the idea that reaching the C-suite means the learning is done. "I don't care who you are, you can always get better."

Leadership development is often organized around events. But meaningful behavioral change happens in the days and weeks between them. The engineer who learned every name in his building was shaped by years of ordinary working days, each one a chance to practice.

The framework reduces to three questions any leadership team can ask: which capabilities, which real situations, and what evidence. Underneath them sits a fourth. Where do the weeks between programs live?

What to take from this

  • Leadership fundamentals hold across industry and company size. Execution is the variable that changes.
  • Formal programs are the right tool for specific skills and knowledge, and the wrong tool on their own.
  • Narrow to a few capabilities, practice them in real situations, then look for evidence of changed behavior.
  • Instruments give you data points over time. The strongest signal is a leader describing a situation they would have handled differently.
  • Development is organized around events. The change happens in the weeks between them.
