Case Study: NTT achieves full visibility into its IT landscape with SAP LeanIX

NTT Group unifies IT data across 900+ subsidiaries with LeanIX

NTT Group, one of Japan's largest telecommunications companies, faced significant challenges due to its sprawling IT architecture. With over 900 subsidiaries, the company struggled with technology sprawl, a lack of visibility into which systems were globally optimized, and no central repository for tracking end-of-life information. To manage its transformation, NTT turned to the vendor LeanIX and implemented its SAP LeanIX Enterprise Architecture Management solution to gain control over its complex IT landscape.

By implementing LeanIX, NTT consolidated all of its previously siloed system data into a single source of truth. This provided full visibility of their IT landscape and ensured all employees, from executives to developers, had access to the same information. The solution allowed them to document the end-of-life status of all systems, which in turn enabled them to identify critical areas and start integration discussions. LeanIX provided the crucial tool that allowed NTT to adapt to the rapidly increasing speed of business.
