More practical terms
Functional Safety Management governs equipment and process safety activities involving safety systems.
The purpose is to reduce the possibility of a SYSTEMATIC FAULT.
IEC 61508 part 4- 3.1.9 define functional safety
part of the overall safety relating to the EUC and the EUC control system which depends on the correct functioning of the E/E/PE safety-related systems, other technology safety-related systems and external risk reduction facilities
Part 1, Clause 5 lays out details of FSM Narrower coverage mange application more manageable
