Achieving operational excellence means focusing on continuous improvement through processes that are repeatable, reliable, and Lean. At CIRCOR, we embrace this approach through our own comprehensive program—the CIRCOR Operating System (COS).

COS aligns people, processes, and technology to empower our employees, making continuous improvement part of the daily experience. It focuses on results-driven leadership; the elimination of waste (cost, time, quality, resource, space); Lean and process controls for speed, flexibility, and efficiency; higher performance for greater market share; and the improvement of cash flow through inventory reduction or increased turns.

The program is comprised of ten key business process attributes—best practices leveraged across all operations.
