What is Functional Safety Management
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
A FSM plan describes the Safety lifecycle

IEC 61508 / 11 version of FSM
FSM focuses of procedures, the standard provide a good reference
61508 cover everything includingwk.baidu.comsafety system hardware and software development
IEC 61511 - Standard Life Cycle
IEC 61511
Defines 61508 application in Process Sector
Defines the Application of Safety Instrumented Systems for the Process Industry
Part 1- Clause 6, lays out details for FSM Broad coverage can make application challenging
61511 focuses on the process owners and safety system users

FSM - Objectives
Specify management and technical activities during the Safety Lifecycle to achieve and maintain Functional safety
Specify responsibility of persons and organizations Extend an existing and monitored quality system

Functional Safety Management
Safety Planning- create a FSM plan Roles and responsibilities Personnel competency Documentation, documentation control Functional safety Verification and assessment Documented processes
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.
