Giving great advice. Interview by Thomas A Stewart and Gardiner Morse

Few deal makers have been at it as long, and at such a high level, as Bruce Wasserstein, the chairman and CEO of the financial advisory and asset-management firm Lazard. In this edited interview, two HBR editors explore how he creates value as a manager, as a deal maker, and as a counselor to CEOs. Wasserstein, who has been a major figure in mergers and acquisitions for more than 30 years, talks about attracting and managing talent, building and sustaining a knowledge business, sizing up industries and companies, and crafting advice to help CEOs unlock value. At the heart of his approach is a singular ability to dissect a strategy's underlying premises in order to figure out whether a plan or deal "makes sense." Part of that determination involves understanding the broader context: Where is the industry going? What external factors will affect it? Such sensemaking informs every move Wasserstein makes, and it has paid off handsomely. In his career, he has helped broker more than a thousand deals, worth hundreds of billions of dollars. His intellect, creativity, and doggedness are what allow him to pick apart the most complex problems and devise novel solutions. In an age of specialization, he recognizes the importance of connecting the dots; he draws on the knowledge and skills of creative generalists as well as industry and regional specialists when setting up and executing deals. Wasserstein studied at Harvard University's business and law schools and at Cambridge University, helped lead First Boston's M&A practice, cofounded the investment-banking firm Wasserstein Perella Group, and then joined Lazard, which he famously took public in 2005 after disassembling a century and a half of family ownership. He is the 2007 recipient of Harvard Law School's Great Negotiator Award.
