For an organization to function effectively, it has to identify and manage numerous linked activities. An activity using resources, and managed in order to enable the transformation of inputs into outputs, can be considered as a process. Often the output from one process directly forms the input to the next.
The application of a system of processes within an organization, together with the identification and interactions of these processes, and their management, can be referred to as the “process approach”.
Core processes at ESO/LSO are published in the LSO Quality Manual.
