On September 1, 2026, after 15 years as CEO, Cook transitioned into the role of Executive Chairman, while John Ternus became Apple’s new CEO. Apple described the change as the result of a thoughtful, long-term succession planning process.  

That’s a significant leadership transition.

But there’s a UX lesson hidden inside it.

Leadership changes. Users shouldn’t have to start over.

Whenever leadership changes, there’s often pressure to demonstrate that things are changing.

New strategy.

New priorities.

New ideas.

New products.

Sometimes, that change is necessary.

But products aren’t experienced by leadership teams.

They’re experienced by users.

And users build mental models over time.

They learn:

Where things are.
How things work.
What interactions mean.
What they can expect.
How the product behaves.

Those expectations become part of the experience.

So when leadership changes, a useful UX question is:

What are we protecting?

The answer might include:

→ User expectations
→ Familiar interactions
→ Design principles
→ Accessibility
→ Brand personality
→ Product quality 

This doesn’t mean products should never change.

Quite the opposite.

Good products need to evolve.

But evolution doesn’t mean throwing away everything that came before.

Change with context

A new leader shouldn’t inherit a product and immediately ask:

“What can I change?”

A better question might be:

“What is already working—and why?”

Then:

“Where is the evidence that something needs to change?”

That’s where UX thinking becomes valuable.

Because design isn’t just about creating something new.

It’s also about understanding the existing system before deciding what deserves to change.

A successful leadership transition can introduce a new direction while maintaining the continuity users depend on.

Apple’s transition from Tim Cook to John Ternus is a particularly interesting example because Cook remains involved as Executive Chairman, providing an element of continuity even as the CEO role changes.  

The bigger lesson goes beyond Apple.

New leadership doesn’t automatically require a new user experience.

Change what needs changing.

Protect what users already understand.

And make every change earn its place.

Leadership changes. Users shouldn’t have to start over.

That’s UX.
