For decades, mainframe applications have powered your business and evolved with changing demands. Today, the introduction of gen AI to boost the efficiency of enterprise systems is essential to remain competitive. Such evolution, combined with rising operational costs, maintenance risks, and growing skills shortages in information systems based on mainframes, is driving organizations to accelerate modernization.

By refactoring their core mainframe systems with Fujitsu towards an agentic-ready cloud-native architecture, while avoiding operational disruptions and capitalizing on proven business processes, organizations upgrade to an era of increased agility and efficiency, while reducing their operational costs by up to 70%.

  • 1. Qualification

    Quick 2-3 week application assessment to roughly validate technical feasibility and estimate financial and planning, based on actual mainframe source code in scope and associated database.

  • 2. Risk mitigation

    Working closely with application owners, Fujitsu’s team of experts assesses the human, financial, and technical assumption to warranty success. As result, the acceptance criteria are clearly defined.

  • 3. Proof of concept

    Based on a 150–200 KLOC of source code in scope (Kilo Lines of Code), this 8-12 week phase validates that based on the technical assumptions, the acceptance criteria are met.

  • 4. Firm price proposal

    As a result of the POC, the acceptance criteria, RACI matrix, project planning, and budget are jointly refined to finalize a firm contractual agreement.
