“psychological resource management” that energizes teams? Every day, we are overwhelmed with countless tasks, including responding to emails, creating documents, one-on-one meetings, negotiating with clients, and coordinating with other departments. Each time, the “thinking,” “judging,” and “executing” required utilizes mental energy. In this book, we define this as “psychological resources,” an essential resource for a team to achieve results. Even the
accumulation of small stresses like “I’m afraid of my boss and hesitate to report,” “I’m unsure how to proceed,” and “It’s a pain to have to fine-tune everything” gradually wears down psychological resources. And before you know it, the energy that team members should be using to create value is being wasted on activities that don’t create value. The feeling of exhaustion across the team may be due to the waste of these “psychological resources.” This book carefully unravels the mechanisms behind psychological resource depletion and presents specific recovery methods for healthy teams to achieve results. Author Mari Sakuramoto has supported over 100,000
businesspeople and provided leadership and team building support to over 270 organizations. This book, compiled based on her extensive experience, takes a fresh perspective on “psychological resources” and is packed with know-how for naturally amplifying those resources within a team and producing results. By increasing the efficiency of mental energy, you can create a rich and sustainably powerful team – a practical management guide for maximizing the potential of each member. ■Table of Contents (excerpt) Introduction Chapter 1: What are psychological resources?
