[New Book Release] Solving the Problem of "Mistakes That Never Go Away No Matter How Many Times You Point Them Out"

Will PM International Co., Ltd. (Headquarters: Tokyo) announces that Jun Ishida's new book, "The Definitive Guide to Eliminating Unending Mistakes," a leading expert in Behavioral Science Management®, was released on April 4, 2026, by Nikkei BP Nikkei Shimbun Publishing.

To commemorate the book's release, a free online seminar featuring the author himself will be held.

■ The Structural Problem of "Mistakes That Never Go Away No Matter How Many Times You Point Them Out" In many companies and workplaces, measures such as "paying attention," "raising awareness," and "thoroughly preventing recurrence" are taken whenever mistakes or accidents occur.

However, in reality, it is not uncommon for issues such as: - The same mistakes being repeated - Improvements only lasting immediately after guidance, then quickly reverting - Variations in quality and safety levels across different workplaces

remain unresolved.

■ An Approach Focused on "Behavior" Rather Than "Awareness" In this book, "The Definitive Guide to Eliminating Unending Mistakes," a perspective is presented that redefines mistakes and accidents not as "people problems" but as "behavioral problems."

- Identifying behaviors that cause mistakes - Defining desired behaviors in a way that anyone can execute - Designing a system to sustain those behaviors

This book systematically explains such a reproducible approach.

■ Author's Comment (Jun Ishida) Jun Ishida, Director of the Institute of Behavioral Science Management®

"Mistakes are not caused by 'lack of attention' but by 'design flaws in behavior.' Instead of trying to change people, mistakes can be reliably reduced by changing behaviors and the environment. In many workplaces, the methods of high-performing individuals remain tacit knowledge. It is crucial to verbalize these as 'behaviors' that anyone can reproduce and incorporate them into a system. This book concretely summarizes these methods in a way that actually functions in the workplace."

■ "Publication Commemoration Seminar" Directly Explained by the Author To commemorate the release of this book, a free seminar featuring the author, Jun Ishida, will be held.

Jun Ishida primarily engages in corporate training and consulting, and opportunities to receive direct lectures from him in public are extremely limited.

In this seminar, based on the book's content, the structure of mistakes will be unraveled from a behavioral science perspective, and specific points for practical implementation in the workplace will be explained.

■ "On-site Case Studies" to be Revealed in the Latter Half of the Seminar In the latter half of the seminar, current WILLPM consultants will present case studies of initiatives in actual corporate workplaces.

- How behaviors were defined - How they were established in the workplace - What results were achieved

Through practical-level specific examples, the seminar is structured to help participants envision how to implement these approaches in their own companies.

■ Recommended for Those Who: - The same mistakes are repeated no matter how many times they are pointed out - On-site training is person-dependent and lacks reproducibility - There are variations in safety, quality, and operational accuracy - Are managers looking for effective guidance methods

■ Event Overview - Date and Time: May 13, 2026 (Wednesday) 15:00-16:00 - Format: Online (Zoom) - Participation Fee: Free - Target Audience: Business owners, HR managers, executives, site managers, training personnel, etc. - Speakers: Jun Ishida (Author) / Gakuro Matsumura (WILLPM Senior Consultant)
