In Practise, a leading investment research platform, has curated a number of interviews with seasoned executives that share timeless insights about how industries and businesses work. The book explores how businesses such as Costco, Constellation Software, LVMH, and TransDigm create value for customers and shareholders. Each interview is with an operator with a minimum of 25 years experience in their field. This edition embodies a core pillar on which we built In Practise - the belief that a carefully conducted interview with an experienced industry practitioner can yield deep insight into the fundamentals of a business and industry. This notion seems to have gotten lost amid the explosion of information and access to experts in recent years. The first volume of a series to be published over the coming years, the book is a collection of interviews that contain long shelf-life insights into how value is created in world-class businesses.
