overhaul
This term conveys a sense of total restoration rather than a simple fix. When applied to machinery, it implies a complete disassembly and inspection to ensure every component is functioning perfectly. It suggests a rigorous, technical process of renewal. In an organizational or systemic context, the word implies that the existing structure is fundamentally flawed or obsolete. It describes a sweeping transformation that replaces old methods with new ones, rather than making incremental adjustments.
