The Safety Management System
A prerequisite for the achievement of functional safety is the creation and
use of procedures and other measures as part of a safety lifecycle,
collectively known as a Safety Management System. The Safety
Management System defines the generic management and technical
activities necessary to achieve and maintain functional safety in the
product design and development. In many cases, the Safety Management
and Quality systems will be integrated within a single set of procedures.
The integrator should have an accredited quality management system.
The Safety Management System shall include:
A statement of the policy and strategy for achieving and maintaining
functional safety.
A safety planning procedure, which shall result in the definition of the
safety lifecycle stages to be applied, the measures and techniques to
be applied at each stage, and the responsibilities for completing these
activities.
Definitions of the records to be produced and the methods of
managing these records, including change control. The change
control procedures shall include records of modification requests, the
impact analysis of proposed modifications and the approval of
modifications. The baseline for change control shall be defined clearly.
Configuration items shall be uniquely identified and include version
information. Examples of configuration items are system and safety
requirements, system design documentation and drawings, application
software source code, test plans, test procedures and test results.
Methods of ensuring that persons are competent to undertake their
activities and fulfill their responsibilities.
