Tokyo Gas i Net, which manages information systems for the Tokyo Gas Group, built a system that uses AI interviews to capture experienced project managers’ (PMs’) experience and decision-making criteria. It will use the knowledge to train junior staff and review project plans. Hitachi Solutions, which built the system, announced it on October 14, 2026.

At Tokyo Gas i Net, PMs’ criteria and know-how for leading system development and operations had remained personal, tacit knowledge that could be lost when they retired. The company needed a way to preserve that expertise as an asset and use it to develop staff, maintaining and improving project management quality.

The system combines Hitachi Solutions’ Interview Support AI Service with Allganize Japan’s generative AI platform, Alli LLM App Market. The interview AI asks experienced PMs questions in a conversational format. Based on their answers, Alli LLM App Market identifies clues to tacit knowledge and generates follow-up questions, which the interview AI presents to the PM. Alli LLM App Market then reads the text transcripts of the questions and answers and builds a knowledge base.

Interview scenarios were created using PMBOK, a project management body of knowledge. They include hypothetical situations PMs often encounter to elicit how experienced PMs think through decisions. Hitachi Solutions says interviews using only its Interview Support AI Service often ended after 15–20 minutes without drawing out enough expertise; with the combined system, interviews lasted 50–60 minutes.

One use is reviewing project plans written by less experienced PMs: the AI offers feedback and advice based on the stored expertise of veteran PMs. Another is assessing the PM who took part in an interview. The AI scores the PM’s skills from the interview results and identifies strengths, challenges, and next steps.

Tokyo Gas i Net plans to consider expanding the system’s use in project management and applying it to other work where passing on experienced employees’ tacit knowledge is a challenge. It is also considering deployment across the Tokyo Gas Group. Hitachi Solutions says the system can extract tacit knowledge through interviews and use it for project plan reviews and PM skill assessments.
