👉 Reengineering is the process of systematically analyzing, redesigning, and rebuilding existing systems, software, or products to improve their performance, efficiency, security, or alignment with new requirements. It involves a deep understanding of the current architecture and functionality, followed by strategic modifications to address limitations, integrate new technologies, or adapt to changing business needs. Unlike mere updates, reengineering often entails a complete overhaul—replacing components, rearchitecting structures, or even rewriting core logic—to deliver enhanced capabilities while minimizing disruptions to existing operations. This approach is critical in industries where legacy systems must evolve to stay competitive, ensuring compatibility with modern standards or emerging technologies without discarding valuable foundational elements.
