When I first encountered generative AI, I thought it was just a slightly smarter chatbot.
But I had no idea this technology would completely transform my life. From writing VBA code for OA programs to creating presentations, editing images and videos, analyzing data, and even developing programs, AI has significantly improved my work efficiency, allowing me to focus on more essential tasks.

The introduction of generative AI is also bringing about revolutionary changes in the HR field.
It enables you to perform a variety of tasks that were previously impossible, and allows you to focus more on core tasks by automating simple, repetitive tasks.
A representative example is People Analytics, which has recently been attracting attention.
This allows HR to move beyond one-way, repetitive tasks and provide personalized services to each member of the organization based on AI and data, providing better experiences and supporting the growth of individuals and the organization.

In the past, people analytics required a wide range of expertise in HR, statistics, data, IT, and human resources organization theory, creating a significant barrier to entry.
But now, with the advent of generative AI, the foundation has been laid for relatively easy access even for general HR practitioners.
As long as you have a clear sense of the problem you want to solve, data-driven human resource management is now fully possible with the help of generative AI.

Against this backdrop, this book was written to help readers experience solving small problems step by step using generative AI.
By personally following the examples presented in the book and using generative AI programs and data from around you to solve similar problems, you'll find yourself significantly improving your AI utilization skills.

The core principles and methodologies covered here can be applied equally to both private and public settings.
The book's contents have been continuously revised and supplemented through studies conducted with Smart HR Lab study group members, including HR managers and staff from large corporations, mid-sized companies, and startups, startup representatives, employees of foreign companies, overseas public sector workers, educators, and human resources organization consultants.
I would like to take this opportunity to express my deepest gratitude to the Smart HR Lab study group members.

In a rapidly changing era, whether you lead the way or fall behind starts with small choices.
Don't hesitate, let's get started right now.
If you are reading this book, you have already taken the first step.
