Lean Manufacturing is a philosophy more than a tool — a coherent set of principles, practices and tools originating in the Toyota Production System in the 1950s-60s and now adopted across global industry. The central principle: systematically eliminate the seven (or eight) wastes (overproduction, waiting, transport, unnecessary processing, inventory, motion, defects, and, more recently, underused talent).
Lean's operational tools include: 5S (workplace organisation), Kanban (demand-pulled production), SMED (setup-time reduction), TPM (total productive maintenance), Kaizen (incremental continuous improvement), VSM (value stream mapping). Each requires cultural discipline as much as technical discipline — which is why lean transformations fail more for human reasons than technological ones.
Well-designed industrial software supports lean without forcing it. KORA Productivity feeds the lean shop floor with real-time information on production, stoppages and defects; it materialises 'genchi genbutsu' (go and see) for those who cannot always be there. The MULTI ERP exposes the quantitative VSM — where the stock is, how long it waits between operations, where the bottleneck sits.
