Gez Smith began his Lean-Agile journey 20 years ago, using The Toyota Way and Scrum to grow a start-up from a bedroom company to working with 10 Downing Street and The White House. Along the way, he became a Product Owner, which was his first insight into how little he knew. A feeling that has only grown the more he has learned. Years later, he moved into financial services, including a spell as Global Head of Agile at HSBC, where he first used SAFe® to help thousands of people around the world get more value delivered more easily. Along the way, he picked up two master's degrees and also became a SAFe® Practice Consultant Trainer (SPCT) and a SAFe Fellow. Outside of the day job, he enjoys blogging, podcasting, and writing, having previously written books on digital engagement, Agile marketing, and Agile HR. He is a regular speaker at conferences, events, and meetups around the world. In short, he likes having ideas and sharing them with other people to see whether they find them useful too, which is why he contributed to this book.
