Case Study: Nihon Housing achieves integrated one‑stop operations and faster, cost‑efficient delivery with GeneXus

Nihon Housing Hou- Net, Integrated System Development the Agile way with GeneXus

Nihon Housing, a Tokyo‑headquartered company founded in 1958 with 46 domestic offices, 2 overseas offices and over 10,000 employees, launched an Integrated System project to combine six core subsystems into a one‑stop operations platform (Hou‑Net). The goals were to improve limited application access, accelerate processing speed, reduce overtime and operational costs, and standardize independently evolved segments. When user requirements grew by up to 22% and a waterfall approach threatened schedule and cost overruns, the team selected GeneXus (with GXportal™) as the new development tool and shifted to an Agile framework.

Using GeneXus and GXportal™, the project team adopted Agile practices, rebuilt the integrated one‑stop system and standardized processes across segments. This change let them accommodate the 22% increase in requirements without delaying the release, speed up development and processing, improve application access, reduce overtime frequency and advance the project’s cost‑efficiency and operational goals — outcomes achieved through GeneXus‑driven Agile development.
