Since 2001, the management ranking organization Thinkers50 has ranked the world's top 50 thinkers in management every two years, based on online voting from a carefully selected shortlist and the input of a panel of experts. 

The organization seeks to identify those select few business thinkers whose writing, research, and work genuinely influences the way leaders and companies operate.  

These thought leaders are evaluated by 10 criteria that measure short-term and long-term influence.

Recent impact, defined as the past two years, is based on the relevancy of their ideas, the rigor of their research, how well they present their ideas, the accessibility of what they produce, and how internationally applicable the ideas are.

The long-term impact, which includes the past 20 years, is based on the originality of the ideas, their effects, how practical they are, if they make real business sense, and their power to inspire.

Last night, in a ceremony billed as "the Oscars of management thinking," the new ranking was revealed. 

15. Amy Edmonson

Edmonson is a professor at Harvard Business School whose work focuses on teaming and collaboration. She also worked with the legendary inventor Buckminster Fuller, and wrote a book explaining his work.

11. Pankaj Ghemawat

Before moving to IESE Business School in Spain, Ghemawat was the youngest full professor ever appointed at Harvard Business School. 

His work focuses on globalization, and he argues that we aren't in one homogenized economy but are much more disconnected than people realize. Those disconnects can be a source of advantage, he says.

His ranking improved 16 points, from No. 27 in 2011.

10. Marshall Goldsmith

Goldsmith is one of the most popular and prominent executive coaches in the world. If you've ever heard of or gone through a 360-degree feedback process, it started with him. 

He's the author, co-author, or editor of more than 30 books and continues to run a top-tier executive coaching group. He came in at No. 7 in the last round of rankings.

9. Herminia Ibarra

Ibarra, a chaired professor at INSEAD, received the Leadership award from Thinkers50 for exceptional work on the subject. This year, she breaks into the top 10, from No. 28 in 2011. 

She emphasizes that the most successful careers aren't linear — the traditional ladder-climbing ascent to senior management — but the result of experimentation. She didn't necessarily follow the advice herself, telling the Financial Times that she first dreamed of being a professor of organizational theory at age 13.

Martin stepped down as dean of the Rotman School of Management at the University of Toronto earlier this year, and remains a professor there. In addition to his third-place ranking, Martin co-wrote "Playing To Win" with Procter & Gamble CEO A.G. Lafley, which earned the Thinkers50 award for most influential business book.

The book focuses on what's become a signature of Martin's, using integrative thinking to break down and solve complex business problems. He was ranked No. 6 in 2011.

2. W. Chan Kim and Renee Mauborgne

Both are professors at INSEAD and the co-authors of the incredibly influential 2005 book, "Blue Ocean Strategy." The book, still talked about eight years later, focuses on creating market space where competition is irrelevant. Some governments, Malaysia in particular, have used their ideas to further their policy efforts. 

The pair came in at No. 2 in the previous ranking, and their next book is expected in 2014.

1. Clay Christensen

Christensen, a longtime professor at Harvard Business School, takes the top spot again. That's unsurprising given how incredibly influential his 1995 book, "The Innovator's Dilemma" and his concept of disruptive innovation remain.

Since then, he's turned his attention to fixing health care and the education system. His most recent book is "How Will You Measure Your Life."
