The date is January 3, 2022.

His CEO tenure is nearly five years.
After the consumer health unit was spun off, the company centered on Johnson & Johnson Innovative Medicine and MedTech.
That fits the wider field of healthcare and medical technology.
Major Achievements and Strategic Priorities
Duato is known for guiding the company through its vaccine response during the pandemic.
He’s also known for the consumer health separation and a sharper focus on medicines and devices.
He reshaped the portfolio through deals such as Abiomed and Shockwave Medical, aiming at faster growing areas.
J&J is putting $55 billion into US research and manufacturing.
The business covers pharmaceuticals and devices, and every launch needs regulatory approval.

- Vision
Patient safety, steady product development, and data science and artificial intelligence all matter here.
Leaders in this field often talk about responsible innovation, meaning new tools that put safety first.

How Their Leadership Approaches Compare
Understanding how their leadership approaches compare starts with the problems each man faced.

McMillon’s Focus on Retail, E-Commerce, and Customer Experience
McMillon’s work centered on the shopper.

He also put effort into associates, since happy employees tend to serve customers better.
His approach to retail operations blended technology with old-fashioned store basics.
Duato’s Focus on Pharmaceuticals, Medical Technology, and Innovation
Duato’s work centers on the patient.
Medicines and devices take years to build and must pass strict reviews before reaching anyone.

Safety comes first in every launch.
