A systematic approach to operations management that focuses on eliminating waste, improving efficiency, and maximizing value for customers while using minimal resources. It emphasizes continuous improvement and respect for people in all processes.
From 'lean' (Old English 'hlaene' meaning 'thin' or 'without excess') applied to Toyota's production system, which was termed 'lean' by MIT researchers in the 1980s. The concept originated from Toyota's post-WWII resource constraints, which forced innovative approaches to manufacturing efficiency.
Lean operations is like Marie Kondo for businesses - if a process, inventory item, or activity doesn't 'spark joy' by adding customer value, it gets eliminated! The brilliant insight is that customers don't care about your internal complexity; they only want their problems solved efficiently, so lean strips away everything else.
