ISO 45001 defines “process” as “a set of interrelated or interacting activities which transforms inputs into outputs”.
Process approach is considered an important part of the management system standards of ISO. It is through a process approach, elements of a complex process are simplified, analyzed and improved.
The processes needed to address risk and opportunities in the health and safety management systems needs to be documented. See the list of mandatory documents required by ISO 45001.
Similarly in the analyzation of process where inputs, activities and outputs are identified and their interaction and interrelation is studied out. The hazards related to inputs, activities, and interrelation of the elements can be easily identified. It is the reason that the process approach is given due important in the OH&S system as well.
