Systematizing Practical Knowledge of Requirement Definition Derived from Real-World Failures: Book 'Secrets of Requirement Definition' Released

ROUTE06 Inc. (Headquarters: Chiyoda-ku, Tokyo; Representative Director: Takashi Endo), which provides AI requirement definition "Acsim," has published the book "Secrets of Requirement Definition: 20 Rules to Prevent Functional Defects, Budget Overruns, and Delays" (Author: Director Hitoshi Matsumoto) through Shoeisha. Based on actual project failures and lessons learned, this book systematizes the know-how of requirement definition into "20 rules" that anyone can replicate in their work. Furthermore, a special booth by Shoeisha will be set up at the "AI Requirement Definition Summit 2026" to be held on June 11th. Those who visit the booth will receive a free copy of this book. ◼️ "Why Do Projects Fail?" - The Answer Lies Not in Implementation, but at the Starting Point "We want to proceed with our projects more safely and reliably." Have you ever thought this? Functional defects, budget overruns, delays – such development failures still occur in many fields today. And many of them originate not in the implementation phase, but in "requirement definition," the starting point of development. To reduce project uncertainty and increase the probability of success, the key lies in how appropriately this upstream process can be designed and executed. This book systematizes the practical know-how for leading requirement definition to success into "20 rules." None of these are mere theories; they are "principles for practitioners" derived from actual project experience, compiled as concrete action guidelines that can be used directly in the field. By structuring requirement definition knowledge and establishing it as a reproducible process, we support the elimination of individual dependencies and the advancement of decision-making. ◼️ Recommended for the following individuals: Engineers/PMs/Product Managers who feel challenges in requirement definition. Development leads and IT departments who want to reduce project delays and rework. Those who want to eliminate the siloing of requirement definition and build a reproducible process. Those who want to systematically learn practical know-how for requirement definition. ◼️ Book Overview Title: Secrets of Requirement Definition: 20 Rules to Prevent Functional Defects, Budget Overruns, and Delays Author: Hitoshi Matsumoto, Director, ROUTE06 Inc.
