The key to successful and steady transformation is an approach that balances modernisation, innovation and stability. In this article, we explore how businesses can achieve this balance and unlock new opportunities for growth.
Why “rip-and-replace” isn’t always the answer
While the urge to entirely replace legacy applications is compelling, it isn’t always the best strategy. Consider this:
The risks of big-bang transformations: Large-scale modernisation projects often require significant time and resources, increasing the likelihood of disruptions, budget overruns, and unmet expectations. A sudden transition can lead to downtime, operational inefficiencies, and a steep learning curve for employees.
Preserving core business functions: Many mainframe applications have been tailored to meet an organisation’s specific needs and play a critical role in day-to-day operations. Replacing them entirely can introduce unforeseen complications, data migration challenges, and the loss of valuable institutional knowledge built over years of usage.
Optimising for agility: A selective modernisation approach allows businesses to focus on areas that provide the most value while maintaining stability in mission-critical operations. By incrementally addressing specific pain points, organisations can respond more flexibly to market demands without overhauling their entire infrastructure.
Applying the 80/20 rule to modernisation
A pragmatic modernisation strategy embraces the Pareto principle—focusing on the 20% of efforts that deliver 80% of the value. Key areas to consider:
Identifying high-impact areas: Organisations should assess which components of their IT systems directly influence customer experience, revenue generation, and operational efficiency. Prioritising these areas ensures that resources are channelled effectively, delivering measurable improvements with minimal disruption.
Addressing bottlenecks: Legacy systems often contain inefficiencies that hinder productivity, such as outdated workflows, slow processing speeds, and integration challenges with newer technologies. Identifying and eliminating these obstacles can significantly enhance business operations.
Incremental value delivery: Deploying changes in small, manageable phases allows businesses to gain early wins and build stakeholder confidence. This approach enables companies to test new solutions, gather feedback, and make adjustments before committing to larger-scale implementations.
Revitalise your legacy systems
Instead of overhauling entire systems, businesses can leverage state-of-the-art technologies to complement and extend their capabilities:
Cloud integration: Cloud platforms offer enhanced scalability, flexibility, and cost-efficiency. By integrating cloud solutions with legacy systems, organisations can achieve greater accessibility and improved performance without major infrastructure changes.
Artificial Intelligence (AI): AI-driven automation can help optimise processes such as fraud detection, predictive maintenance, and customer support. Businesses can harness AI to improve operational efficiency and gain deeper insights into customer behaviour.
Automation tools: Implementing automation solutions can reduce manual workloads, increase productivity, and enhance accuracy in repetitive tasks. Automation can streamline operations across departments, from finance to supply chain management.
Practical strategies for balanced mainframe migration
A successful modernisation effort requires a well-defined strategy that aligns with business goals. Some effective strategies include:
Phased implementation: Dividing modernisation into smaller, iterative phases to reduce risk and adapt to evolving requirements. This approach allows organisations to test changes, monitor their impact, and make informed decisions before scaling up.
Stakeholder collaboration: Engaging business and IT teams early in the process ensures alignment and shared ownership of outcomes. Encouraging collaboration helps to bridge the gap between technical requirements and business expectations. Read more in this article by Valerie Germanese.
Pilot programmes: Testing new technologies in controlled environments before full-scale deployment enables organisations to identify potential challenges and fine-tune solutions. Pilots also provide valuable insights into user adoption and system performance.
A proven approach is here for you
Modernising mainframe applications and data does not have to be an all-or-nothing endeavour. By adopting a pragmatic approach that balances innovation with stability, businesses can achieve sustainable transformation while maintaining core operations. A strategic focus on high-impact areas, and phased implementation can help organisations navigate the complexities of modernisation and unlock long-term value.
