Harvard Places 6 On The Case Centre’s 2025 Bestselling Authors List

The Case Centre has announced its Top 50 Bestselling Case Authors 2024-2025, an annual ranking that highlights the most popular and widely used case writers across global business education. Based on worldwide sales and distribution data, the list recognizes the educators whose work had the greatest impact on teaching and learning in the past academic year.

Harvard Business School makes a strong showing with six authors on the list. The school’s highest-ranked entrant is Christopher A. Bartlett at No. 22.

At the top of the list, the late Debapratim Purkayastha of ICFAI Business School (IBS) retains the No. 1 position for an unprecedented 10th consecutive year. IBS also dominates the overall ranking, with six authors in the top 10 and seven among the 50 listed — more than any other institution.

HARVARD’S CASE LEGACY ENDURES

Bartlett, the Thomas D. Casserly Jr. Professor Emeritus of Business Administration at Harvard Business School, is the school’s highest-ranked entrant at No. 22; his cases on global strategy and multinational management have been staples in MBA classrooms for decades.

He is joined on the list by fellow HBS faculty including Jill Avery (No. 28), David Collis (No. 35), Geoffrey Jones (No. 44), David Yoffie (No. 45), and Ben Esty (No. 50), each of whom has produced widely taught cases spanning topics from consumer marketing to corporate history and competitive strategy.

Elsewhere in this year’s ranking are five new entrants alongside many familiar names. The highest new entry is Fabrizio Di Muro of the University of Winnipeg, who debuts at No. 25. Other newcomers include Stanislav Shekshnia (INSEAD), Vanina Farber (IMD), Ning Su (Ivey Business School), and Nagendra V Chowdary (ICFAI Group).

A LEGACY IN CASE TEACHING

Purkayastha, who died in 2021, remains one of the most influential figures in the modern history of case teaching. The Assam, India native earned his MBA from Utkal University and later completed a Ph.D. at the Kalinga Institute of Industrial Technology. He joined the ICFAI Center for Management Research in 2006 and became a professor of strategy at ICFAI Business School in Hyderabad in 2017. By 2020 he had been appointed director of the ICFAI Case Research Center.

Purkayastha was quite prolific. By the time of his untimely passing from Covid-19 in May 2021, he had authored or co-authored more than 500 cases, which were being taught in nearly 1,600 schools across 95 countries. His cases had reached more than 230,000 students worldwide, making him one of the most widely read case writers of all time. He also broke new ground stylistically, pioneering the use of graphic novel-style cases in collaboration with illustrator Sid Ghosh.

His work has won 13 Case Centre awards and topped the Centre’s list of top 50 cases for an incredible 10 straight years. In 2015 he received the Outstanding Contribution to the Case Method award. Beyond his writing, Purkayastha was an active leader in the global case community, serving as a reviewer, editor, judge, and speaker at conferences and competitions. His continued dominance at the top of The Case Centre’s bestseller list, even years after his death, illustrates both the quality of his cases and the depth of his influence on business education.

OTHER TOP AUTHORS AND THEMES

Notable names rounding out the top tier on this year’s list include Indu Perepu (IBS) at No. 2; W. Chan Kim and Renée Mauborgne of INSEAD, tied at No. 3; and Syeda Maseeha Qumer (IBS) at No. 5. IMD also performs strongly, with Peter Killing (No. 9), Kamran Kashani (No. 10), and Stefan Michel (No. 39) among its representatives. Harvard Business School, London Business School, Ivey, Columbia, and SDA Bocconi also feature prominently.

The top cases themselves reflect both timeless management challenges and new, modern business dilemmas. Purkayastha’s enduring bestsellers often center on corporate strategy, leadership, and organizational change, with a particular focus on bringing Indian and global companies into classroom discussion. Perepu’s widely adopted cases explore sustainability, governance, and ethics, providing instructors with rich material to challenge students on issues that straddle business and society.

Meanwhile, INSEAD professors W. Chan Kim and Renée Mauborgne continue to dominate classrooms worldwide with cases linked to their Blue Ocean Strategy framework, which advises companies to create new, uncontested market spaces (“blue oceans”), rather than competing in saturated, “red ocean” markets.
