How Pfizer’s Luisa Barraza Rewrites the Rules of Transformation

When most executives talk about transformation, they talk about technology. New systems. New tools. New models. But when Luisa Barraza, Chief Vice President of People Experience, Organizational Development, and Transformation at Pfizer, talks about transformation, she flips the script entirely.

For her, real transformation begins long before a new platform is rolled out, and long after the buzzwords fade. It begins with the people. In this episode of “The Shift Code” podcast, hosted by Pierre Le Manh, Luisa shares how two decades at Pfizer have shaped her belief that people, not technology, are the true engine of enterprise agility.

360-degree view of operations

Luisa started her career as an industrial and systems engineer, an intentionally broad field that allowed her to roam. Even early on, she resisted the pressure to specialize. Her instinct was right: the roles she would eventually hold didn’t even exist when she entered the workforce.

Her early responsibilities gave her a foundational project management toolkit and exposure to how culture, regulation, and local realities shape work. Then came the audit. Financial, healthcare, and technology audits across multiple countries gave her something rare: a 360-degree view of how a global organization operates and where transformation dies.

Perception is reality

Moving into marketing expanded Luisa’s lens from systems to people. What resonated with physicians? What made sense to patients? What messaging actually worked globally, and what needed localization?

Marketing taught her two major lessons:

• Strategy must be both global and local. You can design from one vantage point and expect it to scale.
• Perception determines success. You can have the right product, the right idea. However, if people don’t see the value, it fails.

This human-centered insight would become the backbone of her transformation philosophy.

Why transformation fails

AI is reshaping every aspect of business, but Luisa warns that many AI projects are failing for the same reason traditional transformation fails: leaders introduce technology instead of starting with human behavior.

Companies hand teams an AI tool and say, “use it.” However, transformation doesn’t work through imposition; it works through desire. Success comes when people:

• See personal value
• Understand the benefit
• Feel the tool makes their work better

AI doesn’t fail because it’s weak; it fails because the rollout is misaligned with human needs.

The workforce of the AI era

Luisa sees AI accelerating the shift away from manual, operational roles and toward strategic, analytical, and human-centered work. Middle management is especially vulnerable unless it evolves.

Her advice:

• Don’t avoid AI. That’s a losing bet.
• Stay curious.
• Continuously learn.
• Find new ways to bring value.

From change management to change-making

If Luisa had full authority to overhaul agility at Pfizer, she wouldn’t begin with processes. She would begin with the mindset. She would erase the term change management, which she sees as reactive.

Instead, Luisa champions change-making, a culture where change is expected, embraced, and shaped proactively. It’s a simple shift in language with massive implications. And that, ultimately, is why Pfizer continues to adapt, reinvent, and lead, because in Luisa’s world, transformation isn’t an initiative; it’s a way of being.
