In the first edition of this book, the authors introduced a method to measure and improve on information flow for knowledge workers in the modern office. They showed how to adapt the factory-derived Lean body of knowledge into today's service economy and highlighted several useful software tools and trends in collaborative and cloud services. Since the original publication, several other tools have emerged that more closely match the ideas in the book. This second edition builds on its popular predecessor with updates to the software sections and provides refined predictions for the Lean office.
