Many people aspire to entrepreneurship but we all know it's a high-risk endeavor. Bill Aulet, the Ethernet Inventors Professor of Entrepreneurship at the MIT Sloan School of Management, has for decades studied what it takes for start-ups to succeed and advises the next generation of founders on how to do it. He discusses the key trends and changes he's seen over the past few years, and outlines concrete steps anyone can take to get a new venture -- including those within larger organizations -- off the ground. Aulet is the author of the newly updated book Disciplined Entrepreneurship: 24 Steps to a Successful Startup.
