Mary Barra’s Early Career and Rise at General Motors
Mary Barra started at General Motors in 1980 at age 18. She joined as a cooperative education student at the Pontiac Motor Division, working on the factory floor while she studied at the General Motors Institute, now Kettering University.
She earned her degree in electrical engineering in 1985. GM later sponsored her MBA at the Stanford Graduate School of Business. That mix of engineering depth and business training shaped everything that came next.
Her climb was steady. She began in engineering and plant roles, then became plant manager at the Detroit Hamtramck Assembly plant.
Mary Barra as General Motors CEO
Barra became CEO on January 15, 2014, and was later named chair. She was the first woman to lead a major global automaker.
Her first months were a test. The ignition switch recall crisis put GM under public and legal pressure.
She chose to speak openly about the failures and pushed for a stronger safety culture inside the company. She later steered GM through COVID 19 and disrupted supply chains.
Her Bet on Electric and Autonomous Vehicles
Barra set GM on an electric vehicle path and invested heavily in new battery platforms. Progress has not been a straight line.
After US tailpipe rules were relaxed, Barra said GM was on a “different path” and adjusted its plans. GM also announced that an eyes off driving system is planned for the Cadillac Escalade IQ in 2028.
Where GM Stands in 2026
Barra is the second longest serving CEO in GM history, behind Alfred Sloan. GM guided toward up to a $2 billion profit increase in 2026 and more share buybacks. She also continues to push for a “level playing field” with Chinese competitors on tariffs and subsidies.
David Cordani’s Professional Journey
David Cordani was born in 1966 and grew up in Connecticut. He joined Cigna in 1991 and spent his whole executive career there.
He rose through roles in the business, including senior vice president of customer segments and marketing. He became president of Cigna HealthCare in 2005, then president and chief operating officer in 2008. He was named chief executive officer in 2009 and board chair in January 2022.
Like Barra, he learned the business from the inside. He understood customers, employers, and the day to day work of a health insurer before he ever became CEO.
Outside work, Cordani co wrote the best selling book The Courage to Go Forward: The Power of Micro Communities. He also supports the Achilles International Freedom Team of Wounded Veterans and runs a family foundation focused on community health.
David Cordani’s Leadership at Cigna
Cordani led Cigna for nearly 17 years. Fortune reported that revenue grew from about $18 billion to about $275 billion under his leadership.
The biggest move was the 2018 Express Scripts acquisition. It created the Evernorth health services business and turned Cigna from a traditional insurer into a broader health company. Cigna now reports more than 185 million customer relationships and about 67,700 colleagues worldwide.
His Leadership Approach
Cordani focused on affordability and personalized care. He built a pharmacy and health services business next to insurance, and he stayed patient and steady during long projects.
The 2026 Transition
On March 3, 2026, Cigna announced that Cordani would retire as CEO on July 1, 2026, and become Executive Chair. Brian Evanko, the president and chief operating officer, took over as CEO. Evanko has nearly three decades at Cigna and has served as chief financial officer.
Cigna reported first quarter 2026 revenue of $68.5 billion and raised its full year earnings outlook. A planned handover during a strong quarter is a good example of succession planning done well.
Mary Barra and David Cordani Have Different Industries
Cars and health care do not look alike. But the gap between their industries makes the common themes more useful.
| Area | General Motors (Barra) | The Cigna Group (Cordani) |
| Main product | Vehicles and mobility technology | Health insurance and pharmacy services |
| Biggest pressure | EV costs, tariffs, regulation | Costs, regulation, public trust |
| Key technology | Batteries, software, autonomy | Data, digital tools, AI |
| Key customer | Drivers and fleets | Employers, patients, governments |
| Defining deal or crisis | 2014 recall | 2018 Express Scripts deal |
Both companies are heavily regulated, capital intensive, and tied to the daily lives of millions of people. Both leaders have faced public scrutiny, and both have had to earn trust again and again.
Their Leadership Experiences Have Common Themes
When you place the two careers side by side, five patterns show up. First, both stayed a long time inside one company, Barra since 1980 and Cordani since 1991. Second, both gained broad experience across several departments before the top job.
Third, both made big strategic bets on a new direction. Fourth, both showed public accountability during hard moments. Fifth, both communicated in a calm, steady way.
These patterns matter for readers building their own careers. Neither leader jumped from company to company chasing titles. They built deep knowledge and trust, and that became their edge.
Innovation Has Been Important to Both Leaders
Innovation sits at the center of both stories, but it looks different in each industry.
Innovation at General Motors
Barra has pushed GM toward electric vehicles, software defined features, and automated driving.
She has also talked about AI tools that let designers test the aerodynamics of a concept in minutes instead of weeks. That speeds up design and cuts cost.
Innovation at Cigna
Cordani expanded Cigna into pharmacy services and health services through Evernorth. The company has also tested rebate free pharmacy models and uses data and AI to simplify care. His successor has said he wants to lean even more on consumer focused, AI enabled services.
Both leaders show that innovation is not only about new products. It is also about changing business models and processes.
The Importance of People in Their Leadership Stories
Neither company can run without people. Barra and Cordani both talk about teams, customers, and communities more than about themselves.
Barra has been reported to answer every letter she receives by hand, even while running a company with tens of billions in revenue. She also credits employees, suppliers, and dealers when GM posts strong results. Cordani’s book promotes micro communities, the small circles of family, friends, and colleagues that help people move forward. He says a CEO is “in the service of the company,” which signals a steward mindset.
This people first approach builds trust. Employees follow leaders who listen, give credit, and own mistakes. Customers and investors notice too.
Their Careers Show Why Adaptability Matters
Barra dealt with the 2014 ignition switch recall, the COVID 19 pandemic and chip shortages, changing EV rules and demand, and trade tensions with China.
Cordani dealt with health care cost pressure, public debate over insurers and pharmacy benefit managers, a very large merger with Express Scripts, and the rise of AI in health services.
In both cases, the leaders adjusted the plan without dropping the larger goal. Barra often says progress is not linear. That is a useful rule for any career: keep the direction, change the route when facts change.
Mary Barra and David Cordani as Examples of Long Term Leadership
Barra has been CEO for more than twelve years. Cordani led for nearly seventeen. In a world where many CEOs last only a few years, that is rare.
Long tenure worked for them because it built credibility with boards, employees, and investors. It also let them finish multi year strategies, understand the culture of their company, and develop internal successors.
Cordani’s handoff to Evanko shows how a long serving leader can leave on a clear plan. Barra’s succession is still an open question. Reports note that her biggest goals, including the EV and software shift, are still unfinished.
What We Can Learn From Mary Barra and David Cordani
Here are the top lessons you can apply today:
- Learn the business from the ground up. Barra started on the factory floor, and Cordani worked through several divisions.
- Stay curious, speak plainly in a crisis, and make bold but measured bets. EVs for Barra and Express Scripts for Cordani are good examples.
Beyond these two points, put people first, because teams and customers drive results. Plan your succession, because good leaders prepare the next leader. And adapt without losing direction: change the plan, keep the purpose.
To apply this in your own career, ask for roles in different departments, find a mentor inside your company, and take on a hard project before you feel ready. Write down what you learn after every setback.
