■ 3 Key Points of the Survey Results
1. Business Efficiency Tops at 30.6% of All Challenges
Among the challenges the 245 companies aimed to solve, business efficiency was the most common at 30.6%. Using the cost and man-hour reductions gained through efficiency as a foothold, an increasing number of companies are advancing to the next maturity stages of "knowledge utilization" and "new value creation."
2. 55.9% of Adopting Companies Choose In-House Development
Only 44.1% of companies remained with the use of general-purpose external tools, while more than half chose insourcing and specialized development utilizing their own proprietary data and confidential information. The movement to position AI as a "source of competitive advantage" has become distinct.
3. 61.6% Reached Stage 2 (Retention Phase), 24.1% Advanced to Stage 3 (Transformation Phase)
In an analysis classifying the maturity of Generative AI utilization into three stages, 151 out of 245 companies (61.6%) reached the phase of "implementation into specific operations and creation of quantitative effects." Furthermore, one in four companies (24.1%) has advanced to the "transformation phase," where they promote new business creation and organizational reform premised on AI.
■ Why We Conducted This Survey
Our company's mission is to "Trigger another period of rapid economic growth," placing labor force supplementation by Generative AI and the maximization of human creativity at the core of our business. After the PoC phase in 2023-2024, corporate Generative AI utilization is transitioning to the "production implementation" phase from 2025 onwards.

On the other hand, there was limited public material providing a cross-industry overview of "what operations competitors are applying AI to" and "whether a company's own challenges are common across other industries."
We created this material to visualize the current landscape, based on over 2,000 case studies accumulated through our Generative AI-specialized media "Taskhub Magazine," which attracts 3 million annual PVs, and our track record of over 1,000 internal projects.
■ About the Chaos Map
This Chaos Map was independently researched and created by our company based on public information such as corporate websites and press releases. It lists companies working on the introduction and utilization of Generative AI, categorized by industry and by "in-house developed tool deployment" versus "external tool introduction."

Finance (Banks/Securities/Insurance) / IT & Telecom / Manufacturing & Makers / Advertising, Media & Entertainment / Trading & Retail / Real Estate & Construction / Infrastructure, Transport & Logistics / Food, Chemicals & Materials / HR, Education & Consulting / Medical & Welfare
