User's Challenge

「I want to plan the modernization of a legacy system.」

I am an IT Systems Director at a major logistics company with 1,000 employees. System renewal is a pressing issue—our core system, which has been operating for over 20 years, has seen maintenance costs balloon significantly. I want to develop a phased modernization plan, but I'm uncertain about where to start.

Selected Approach

Modernization Strategy Matrix

Strategy

We evaluate current system subsystems on two axes—"business value" and "technical debt (maintenance risk)"—to determine modernization priorities and implementation approaches.

It is optimal for logically organizing which functions should be prioritized and what methods should be used to modernize a large-scale system that has been in operation for over 20 years.
