When a crab moves shells, they are exposed and vulnerable. They leave the protection and security of their existing shell in search of a chance to grow into a larger one. Just like people and organizational transitions.

The difference for people is that they are vulnerable for much longer. Instead of taking a few minutes to settle in, a manager will spend months feeling exposed as they get comfortable in a new role. During that time, every habit, every instinct, every pattern they built in the old role is on full display.

Many managers get promoted because they were great individual contributors. They do good work, know the business processes, the clients, and deliver results. When they step into a bigger role, it can be hard to let that go.

Initially, it isn’t a problem. Things work because the manager knows everything, responds quickly, and keeps the team running smoothly. But it doesn’t scale, and they quickly become a chokepoint. People wait for approvals that didn’t previously require waiting. Decisions that should take an hour now take a week. The manager feels overwhelmed, and the team feels micromanaged. The behavior hasn’t changed; it’s just been amplified into a larger space. And the harder they work to keep up, the more it magnifies the problem, and the longer they’re exposed.

One complaint I often hear from managers scaling up is that their teams aren’t meeting the quality standards they expect or require. This happens during transitions. When they had a small team, they could keep expectations in their head and communicate them through daily interactions. A quick correction or an impromptu conversation would result in the improvement needed.

But as the team scales, the manager can’t always be there. With informal enforcement gone, quality drifts, and they can’t understand why, because the standards seem obvious to them. However, they weren’t obvious. They were just always present because the manager was involved in the details.

Conflict often grows during transitions as well. Managers are often mediators, resolving tension before it becomes visible. With a small team, this keeps things running smoothly and productively. When the manager moves up or takes on more responsibility, the small tensions that used to be handled quietly start to compound. By the time they notice, the problem has grown beyond a quick conversation.

These aren’t failures. They’re habits that didn’t scale. The transition didn’t cause the problem; it made the problem visible. The manager is the single point of decision-making, the unofficial quality control, and the unspoken standard-setter. What was manageable with six people becomes unmanageable with eighteen, and they’re working harder than ever but falling further behind.

This is true whether the transition is a promotion, leading a rapidly growing team, or absorbing a new group after a reorganization. The dynamics are different, but the principle is the same: transitions don’t create leadership problems, they expose the ones that were already there.

Managers with ambitions to move into a bigger role should honestly evaluate how they’re operating in their current one. The habits they’re building today will follow them into their next role, team, and level of responsibility. The behaviors they practice at this level get amplified at the next.

Preparation starts with self-awareness. Managers must build a habit of honestly assessing themselves and their teams. There are practical tools managers can use to identify where their personal involvement is what makes things work. That will be a weak point during a transition.

For instance, I always find it curious when managers tell their employees to take a vacation and disconnect, but then they don’t do the same themselves. At some level, I understand. It can be easier to just work a little during vacation rather than prepare to be totally gone. But managers who do this are missing a golden opportunity. Fully checking out for a week and observing what happens upon return is one of the most revealing tests of readiness. I call it the Vacation Test. When a manager returns from vacation, I encourage them to notice what happened. How were decisions made? Where did quality slip? Who stepped up?

There is a simpler version of this. On Friday afternoons, managers can ask themselves what would have happened if they hadn’t been there that week. Where would decisions have stalled? Where would standards have been ignored? The answers will show where they’ve built dependency and where they’ve built discipline.

Managers who are ready to start preparing for a transition should consider two practices that will change how they operate.

Distribute operational ownership. Managers can review their operational duties and start moving them to the team. For example, they can identify a standing meeting to move to a team member. They coach them on the intent and desired outcomes, give them freedom to adjust, and then set a date to stop attending.

The goal isn’t to hand off just a single meeting, though. It’s about building a pattern where operational work runs through the team rather than the manager. They must be systematic about identifying other responsibilities to assign, providing support, and following good delegation principles. Each time a responsibility is successfully moved, the manager’s role shifts from operator to leader, and the team’s capacity grows.

Start a playbook. This documents the recurring decisions, standards, and operating norms that currently live only in the manager’s head. It becomes a living record of how work gets done, how decisions get made, and what good looks like. When those things are written down, they become the team’s standards, not just the manager’s preferences. A playbook allows new team members to onboard faster and enables existing team members to make decisions with confidence. When the transition comes, the playbook becomes the bridge between how the manager led and how the team continues to operate.

A playbook also forces clarity. The act of writing down “this is how we handle X” often reveals that the standard was more vague than expected. That is the benefit of creating the playbook now. It means catching the gap early, while the team is small enough to course-correct, rather than discovering it after a transition, when the consequences are greater.

Both of these behaviors are investments that can start this week. Neither requires permission, a budget, or a reorganization. And they compound. A manager who practices distributing ownership and codifying standards for six months will find their role and their team structurally different. They’ll be ready when the opportunity to move up arrives.

Organizations change and grow. People leave, others get promoted, and vacancy chains form. When a manager’s turn comes, they’ll be exposed, revealing every habit, pattern, and operating behavior they’ve built.

The managers who settle into their new shell and start succeeding in the new role aren’t the ones who figured it out during the move. They are the ones who built a foundation before the opening appeared. They distributed decisions, codified standards, and developed their team’s capacity to operate without them in the room.

Transitions don’t create readiness; they expose it. The best way to prepare for a bigger shell is to outgrow the current one in the right way.
