Modernisation without risk: Slice & Dice instead of Big Bang

Legacy software is a term that refers to outdated software systems that are often still used in critical business processes. These systems have often grown over the years and no longer meet current technical standards. Sticking with such systems entails numerous problems:

• High maintenance costs: The care and maintenance of older systems is becoming increasingly expensive.
• Incompatibility: Legacy software is often incompatible with modern technologies, which makes integrations more difficult.
• Security risks: Outdated systems often have security vulnerabilities that are difficult to fix.
• Adaptability: Adapting to new business requirements is difficult and time-consuming.

Many companies fear the «big bang», where the entire system is replaced at once and the old legacy system is switched off completely. This can lead to considerable disruption and downtime. In contrast, the Slice-and-Dice approach offers a gradual renewal of the individual modules, which prevents a sudden failure and keeps operations running continuously.

The Slice & Dice approach in software reengineering divides the modernisation process into two main phases. First, the software is divided into smaller parts («Slice»), followed by the targeted redesign and integration of these parts («Dice»). This approach helps to carry out the modernisation in a systematic and controlled manner.

Slice: breaking down the software into smaller modules

In the «Slice»-phase, the legacy software is broken down into smaller, realisable modules. This step serves to identify and group the functional units of the software. A detailed analysis of the existing application is used to create logical slices that serve as the basis for the modernisation plan.

Dice: step-by-step modernisation of the slices

The «Dice»-phase refers to the actual modernisation of the identified slices. These are modernised step by step without having to shut down the entire system. New components are developed and integrated while ensuring compatibility at all times.

Objectives of the Dice:

• Modernisation of the software in small, controlled steps.
• Integration of new, modern components into the existing structure.
• Ensuring a smooth migration without interrupting operations.

Procedure:

• Development and integration of new components.
• Continuous testing and monitoring of changes.
• Gradual rollout into production to avoid a big bang scenario.

Stress-free software modernisation without a big bang

Modernising legacy software doesn’t have to be a nightmare. With the Slice & Dice approach, soxes offers a structured and controlled way to bring your outdated systems up to date. Instead of facing a sudden, high-risk big bang, we can take a step-by-step approach and future-proof your organisation.
