Nikkei BP, 7th edition, April 25, 2025, Price: 1870 yen (tax included), 239 pages This book explains from all angles the fundamental concept of "human weakness" that underpins Keyence, a company with extremely high profits. The concept of human weakness is to view people not as inherently good or evil, but as inherently weak, and to establish business-related systems and structures based on that premise. By examining whether your company's daily activities are based on the concept of human weakness, you can design the same systems as Keyence. You will understand what distinguishes Keyence from typical companies and what perspectives to adopt to make changes.
