The Promotion Test Most Leaders Miss

Most leaders think about promotion as an individual question.

Can I handle the next level? Can I manage more complexity? Can I lead a larger team, a bigger region, a more strategic customer base, or a more visible role?

Those questions matter. But they are incomplete.

The better question is whether the work becomes fragile when that leader moves. If every hard decision still comes back to one person, if the customer relationships are held by one person, if the context sits in one person’s head, then the leader has not built capacity. They have built a bottleneck.

That bottleneck can hide inside strong performance. The team hits the number. The customer gets the answer. The supplier relationship stays steady. The leader looks effective because the work keeps moving.

But the system is not stronger if it only works while that leader is present.

That is why succession planning cannot be treated as a form, a chart, or a once-a-year talent review. It has to show up in how responsibility is handed over before the role is open. It has to show up in who gets context, who gets visibility, who gets feedback, and who is trusted with decisions before everyone agrees they are fully ready.

The Bench Does Not Build Itself

Succession planning often fails because organizations treat readiness as something to identify instead of something to build.

A name gets placed in a box. Someone is labeled high potential. A leader says, “We have someone in mind.” But being close to the work is not the same as being ready to carry the work.

DDI’s succession planning research is direct about the business impact: companies with a high-quality succession planning strategy are 2.9 times more likely to achieve high internal promotion success rates and 2.8 times more likely to outperform industry peers financially.

That makes sense. Internal promotion only works when people have been given the judgment, context, and exposure before the title changes. 

In technical organizations, this matters even more. A successor does not only need tasks. They need to understand trade-offs, customer history, supplier dynamics, product constraints, regional differences, and how decisions are made when the data is incomplete. They need to know when to move fast and when to slow down. They need to understand which problems are urgent and which ones are just loud.

That is not built by adding more work to someone’s plate. It is built by teaching the thinking behind the work.

Readiness Starts Before the Role Opens

The strongest succession work happens long before the organization needs a replacement.

It happens when a manager invites someone into the decision, not just the task. It happens when a team member is asked to lead a customer conversation with support nearby. It happens when a leader explains why a decision was made, what trade-off mattered most, and what risk would have changed the answer.

It also happens through feedback. Not delayed feedback. Not vague feedback. Fast, specific, respectful feedback while the moment is still fresh enough to learn from.

That is where Jeff Newell’s point lands. Succession is not separate from day-to-day leadership. It is the result of day-to-day leadership.

A leader who wants to move up has to build the person behind them. That does not mean abandoning the work or pushing people too fast. It means creating enough stretch that the next layer starts learning how to carry real responsibility before the business depends on them doing it alone.

Listen to the full conversation with Jeff Newell on the Leadership in Manufacturing Podcast.

The practical leadership move is simple: choose one responsibility you currently own and identify who needs to start learning it now.

Do not just delegate the task. Teach the context. Explain the judgment. Stay close enough to coach, then let the person carry a real piece of the work. That is how the next layer gets stronger before the gap appears.
