Agile manufacturing is an operational strategy focused on inducing velocity and flexibility in make-to-order or configure-to-order production with minimal changeover time and interruptions. It differs from lean manufacturing in that lean is for high-volume/low-mix production while agile is for low-volume/high-mix. Agile manufacturing applies to environments where customized orders provide a competitive advantage. The main characteristics of agile manufacturing are short time-to-market, modular design/assembly, and configurable components. A major challenge is the high capital required for production/assembly flexibility, but payback periods are often less than two years.
