As software alone – which can be considered as pure information – cannot cause any harm by itself, the term software safety is sometimes dismissed and replaced by “software system safety” (e.g. the Joint Software Systems Safety Engineering Handbook [8] and MIL-STD-882E [9] use this terminology).
For military aerospace and defense systems MIL-STD-882E addresses functional hazard analyses (FHA) and determining which functions implemented in hardware and software are safety significant. The Functional safety focus is on ensuring safety critical functions and functional threads in the system, subsystem and software are analyzed and ...
A United States data item description (DID) is a completed document defining the data deliverables required of a United States Department of Defense contractor. [1] A DID specifically defines the data content, format, and intended use of the data with a primary objective of achieving standardization objectives by the U.S. Department of Defense.
MIL-STD-967 covers the content and format for defense handbooks. MIL-SPEC: Defense Specification: A document that describes the essential technical requirements for military-unique materiel or substantially modified commercial items. MIL-STD-961 covers the content and format for defense specifications. MIL-STD: Defense Standard
The U.S. Department of Defense Standard Practice for System Safety (MIL–STD–882) places the highest priority on elimination of hazards through design selection. [21] One of the most common fail-safe systems is the overflow tube in baths and kitchen sinks.
The SDR was originally defined in the Air Force's MIL-STD-1521. [ 1 ] The SDR is a technical review conducted to evaluate the manner in which a project's system requirements have been allocated to configuration items , manufacturing considerations, next phase planning, production plans, and the engineering process that produced the allocation.
Processes are intended to support the objectives, according to the software level (A through D—Level E was outside the purview of DO-178B). Processes are described as abstract areas of work in DO-178B, and it is up to the planners of a real project to define and document the specifics of how a process will be carried out.
Like DOD-STD-2167, it was designed to be used with DOD-STD-2168, "Defense System Software Quality Program". On December 5, 1994 it was superseded by MIL-STD-498, which merged DOD-STD-2167A, DOD-STD-7935A, and DOD-STD-2168 into a single document, [4] and addressed some vendor criticisms.
