Operations Management draws from various theories to optimize processes, enhance efficiency, and manage resources effectively. Key theories include Taylorism, focusing on scientific management principles for workflow efficiency; Fordism, emphasizing assembly line production and mass manufacturing; Lean Management, prioritizing waste reduction and continuous improvement; and Total Quality Management $($TQM$),$ aiming for quality enhancement through employee involvement and customer focus. Additionally, theories like Six Sigma offer methodologies for defect reduction and process improvement, while Just$-$in$-$Time $($JIT$)$ emphasizes minimizing inventory and maximizing production efficiency. How do these theories converge to address the complexities of modern operations and supply chain management?
