The level and detail of a Reliability Block Diagram (RBD), or set of RBDs, will vary and, in general, reflect a customer's requirements in respect to the bid or project requirement.

All reliability and maintainability data used within this appendix should be obtained from the predictions.

System design and configuration information necessary for the preparation of RBDs shall be obtained from the appropriate project manager who will have designated system design engineers responsible for major sub-systems of the equipment.
