Taisei Corporation shapes the next generation of talent with AI Taisei Corporation vormt de volgende generatie talent met AI

Founded in 1917, Taisei Corporation is one of Japan’s leading construction companies. For more than a century, it has delivered projects in Japan and around the world, helping to build the social infrastructure that supports modern life.

Recently, a new question has come into focus: What should Taisei build next? The company began to ask whether its most important investment should be not only in buildings and infrastructure, but in people.

With this in mind, Taisei’s HR organization decided to introduce ChatGPT Enterprise as a cornerstone of its talent development strategy. Rather than treating generative AI as a simple productivity tool, Taisei positioned it as a technology for expanding human potential.

While many companies look to AI mainly to improve efficiency, Taisei started from a different goal. The introduction of ChatGPT Enterprise was led by the HR organization with a clear focus on people development.

At the center of this decision was a belief that AI is more than a tool. It is something that can extend human potential and reshape how people work.

People development has long been a core management priority at Taisei, and ChatGPT Enterprise fits directly into that strategy. The aim was not simply to increase the number of AI users, but to create an environment where employees learn with AI and grow independently over time.

For the company wide rollout of ChatGPT Enterprise, Taisei adopted an approach it calls Middle Out, combining direction from leadership with energy from the front lines.

The idea of Middle Out grew from the need to bridge top-down strategy and frontline realities. Based on this model, Taisei designed training programs, internal events, communities of practice, and hackathons so AI could spread through practical daily use.

Because of this approach, messages from the top reached the front line, and ideas from the front line spread across the organization.

As AI started to appear in more day-to-day work, Taisei focused on handling information in a way that was both useful and safe. Working closely with the Information Planning Department, the team introduced access controls, usage logs, education programs, and regular monitoring.

By combining governance controls with ongoing enablement, Taisei created an environment where employees can rely on AI in daily work with confidence.

Since introducing ChatGPT Enterprise, Taisei has seen clear measurable impact, including strong weekly adoption, substantial time savings per employee, and thousands of custom GPTs created.

The more meaningful change is happening on the ground as employees across experience levels use AI to elevate the quality and speed of their work.

Taisei’s vision is a future where every employee is comfortable using AI, talent grows directly from work on the ground, and those changes become part of company culture.

The company now aims to share the human-centered AI model it has built with OpenAI across the construction industry and eventually with society at large.
