Document Hierarchy

The Laboratory’s document hierarchy ensures top flow down of policy requirements to all levels of documentation created at the Laboratory and to all levels of the organization.


Laboratory Policies: These are top-level documents that provide the rules for the Laboratory. Laboratory Policies are Directorate level and apply to all employees, contractors, users, and collaborators. They are the expression of the management’s philosophy and are the management documents for the Laboratory. Policies are identified by unique titles and are organized by Management System Owner.

Programs: Defines what the activity is, who performs it, and when it is performed. These are detailed step-by-step courses of action for carrying out policy, program, or project elements. These are documents developed by D/S/C Heads/Project Managers (D/S/C/P) or their designee to implement the laboratory-wide policies formulated by the Directorate. These programs may be laboratory-wide or directed to specific activities as deemed appropriate. Programs consist of statements of strategies and objectives, and methods used to accomplish policy objectives.

Procedures/Work Instructions: Defines how the activity is performed. These are documents describing specific activities and tasks within an organization. It contains the greatest amount of detail. Procedures will be reviewed and approved by the appropriate issuing organization. Laboratory-wide procedures will be developed where a standard approach throughout the Laboratory is agreed upon, and will be approved by the Director or their designee (e.g. procedures for obtaining protective footwear and eyewear). Line management is responsible for the implementation of procedures.

Records: Proof or evidence that an activity has been performed. These are documents pertaining to a specific activity that are evidence of proof that a specific activity occurred, and/or that a policy requirement has been met.
