Formalizing COD/OD makes the difference between good and great control of process safety risks. Leadership in process safety requires clear direction, clear communications, and disciplined execution. Presented at the 7th Global Summit on Process Safety on November 29, 2023 in Himeji, Japan, this presentation covers a model of COD/OD for process safety management, examples of applications, and expected value and improvement potential.
