An objective can be strategic, tactical, or operational.
Objectives can relate to different disciplines (such as financial, health and safety, and environmental goals) and can apply at different levels (such as strategic, organization-wide, project, product, service and process (3.3.5)).
An objective can be expressed in other ways, e.g. as an intended outcome, a purpose, an operational criterion, as an environmental objective (3.2.6), or by the use of other words with similar meaning (e.g. aim, goal, or target).
