Authors: Amane Sawatari and Yoshinori Shimousa “The Genius of Teamwork” (Diamond Inc.) ■ Truly capable workers don’t work “alone.” All the techniques used by people who can successfully manage teams and projects Work cannot be completed by one person. All work is based on teamwork, whether it’s cross-departmental or cross-professional projects, collaborations with other companies, local communities, or government agencies. Despite this, many people struggle with relationships with their coworkers, feeling friction and isolation. This book uncovers the techniques of co-creation required for this modern work style. Authors Amane Sawatari and Yoshinori Shimousa are at the forefront of organizational change and design management. Drawing on their experience supporting over 400 sites, they propose a new type of teamwork (co-creation) that goes beyond traditional teamwork that relies on position or money to motivate people and draw out each other’s motivation and abilities. The essence of co-creation is understanding the differences between yourself and others and connecting with them to achieve results. This book systematically explains the nine elements and 35 capabilities needed to achieve this. It also introduces a wealth of concrete frameworks and examples, offering practical actions for achieving results as a team. It’s useful not only for leaders but also for team members. From individual play to “co-creation” team play. In an era where diverse talent comes together, this is a must-read for turning differences in environment, generation, and values into strengths and maximizing team results. ■Table of contents Introduction Chapter 1: Aligning the “Goal Image”
