Despite being separate, they are dependent upon each other and work together in harmony to form the cohesive basis for efficient and effective operations within an organization 1. An everyday example of mechanism/policy separation is the use of card keys to gain access to locked doors. Sample Scenario q/dev/lp is owned by root with protection rw-----ßThis is used to access the printer When developing policies and procedures for your own company, it can be very beneficial to first review examples of these types of documents.
