[Essential for the AI Era] New Book 'The Map of System Development' Published to Provide a Comprehensive View of Modern Tech Without Coding

Plus Value Inc. (Headquarters: Minato-ku, Tokyo; CEO: Toshiko Kutsuzawa) is pleased to announce the publication of its new book, "The Map of System Development: How to Boost Your Market Value in the AI Era by Building an 'Engineer's Perspective'" (Author: Ryota), under the Plus Value Lab Tech Books imprint.

### A Book That Answers "Why Don't I Understand?"
With the advancement of Generative AI and cloud technologies, system development is becoming increasingly sophisticated and complex. Meanwhile, traditional technical books are often criticized for being "too difficult to finish" or "disconnected from one's actual work."

This book defines the root cause as the "lack of 'Why' in development" and deciphers the underlying reasons behind every process, tool, and decision.

### Features: Moving from "Understanding" to "Visualizing"
The purpose of this book is not just to acquire knowledge but to gain a state where "the structure of development becomes naturally visible."
- Organizes the entire flow from requirement definition to operation and AI utilization.
- Explains the essence of Waterfall and Agile in simple terms.
- Provides cross-cutting understanding of Cloud, Security, Generative AI, etc.
- A new learning design that does not presuppose complex coding.

Through this, readers can gain an "Engineer's Perspective" that allows them to overlook the entire system development process rather than holding fragmented knowledge.

### Recommended For:
- Beginners aiming to enter the IT industry.
- Engineers looking to systematize their technical understanding.
- Business professionals involved in DX promotion and IT projects.
- Management seeking a perspective that connects technology and business.
