Key strategies to fast-track legacy system modernization

Mainframe modernization can be challenging due to inherent complexity, security and compliance concerns, fear of business disruption, and cultural issues. However, the right legacy modernization strategy—aligned with core business needs—can help retail and consumer products organizations surmount their modernization challenges to compete in a dynamic marketplace, power innovation, and drive long-term growth.

1

Reduce complexity with industry clouds and AI

Fragmented legacy systems create complexity. Tame it with industry clouds and AI-assisted tools to integrate systems while maintaining functionality. A sound business case is also key to success.

2

Boost security and compliance with AI

Sensitive data requires strong security to protect it. To strengthen security, perform a holistic security audit, use encryption, and deploy AI-assisted tools to detect threats and monitor compliance.

3

Minimize disruption with a phased approach

Modernization comes with business disruption risk. Reduce it by using a phased approach that aligns with business needs and expected value. Use AI-assisted tools to spot and mitigate disruptions.

4

Solve cultural issues with training and automation

Talent gaps and cultural issues impede modernization. Solve them with upskilling and enhanced recruiting practices, and emphasize knowledge transfer. Automate where possible to enhance efficiency.

A global retailer, aiming to boost efficiency, undertook an initiative to consolidate systems and address data lineage issues—especially for supply chain components. During the assessment process, one system with unparallelled "anywhere-to-anywhere" functionality emerged as a priority focus. Exploring both custom and common enterprise packaged solutions, Deloitte helped the retailer align business and IT goals, weigh modernization scenarios, and analyze costs to determine the best path forward. They also identified accelerators to mitigate risks and expedite the process.

The time to modernize is now

Legacy system modernization is a strategic imperative for retail and consumer products organizations. It can enhance customer experiences, boost efficiency, and position the business for faster innovation and sustained growth. In short, mainframe modernization can deliver long-term success in an increasingly competitive, dynamic market. The mandate to modernize is clear. It’s time to take the leap.
