Value Creation

SI Project Development

  • I have more than 25 years of project management experience in large-scale social system projects such as government agencies, government-affiliated financial institutions, and large-scale financial institutions. Many customers have highly evaluated me for my planning, risk management, and quality management from the perspective of the entire system.
    In FY 21 I proceeded with a major revamp of Fujitsu's development standards (SDEM) that addressed both modernization of existing systems and DX.
    At the same time, as an expert in DX and system reconstruction, I am supporting projects in various industries.

Holding study meetings for customers

  • For customers who already have an existing system and are looking for DX, we hold study sessions that combine system reconstruction and DX knowledge. Ministry of Economy, Trade and Industry “Crossing the River of Digital Transformation” and IPA's system restructuring guide were utilized to hold the event with the theme of the concept and promotion method of modernization (system restructuring) in DX.
    My explanation relating the concept of system reconstruction to DX and my practical experience in system reconstruction have been highly evaluated.
  • For customers who are considering restructuring the system, we hold a study session focusing on the “collection of points - 7 pitfalls to watch out for and their countermeasures” released by IPA. How to proceed with system reconstruction, risks, etc. are explained in detail from “User's Guide for Successful System Reconstruction”.
    Q/A based on my practical experience.
