Title:Software Reliability Program Implementation Guide
Issuing Committee:G-11 Rmsl Software Committee
Scope:In 1994, the SAE G-11 Reliability, Maintainability, Supportability and Logistics (RMSL) Division chartereda software committee, G-11SW, to create several software standards and guidance documents acrossthe RMSL spectrum, including a software reliability program standard and implementation guidelines.The committee was formed as a cross section of international representatives from commercial industriesand governments.The G-11SW committee has developed a standard (JA1002) and these implementation guidelines(JA1003) that are consistent with a SAE G-11 system level reliability program standard (JA1000) andguidelines (JA1000-1), augmented by necessary software-specific information. The G-11SW committeebelieves these documents reflect the best current commercial practices, and meet the objectives of theUnited States Department of Defense Acquisition Reform initiative and the North Atlantic TreatyOrganization (NATO) Reliability Program. The JA1002 program standard is intended to be used byindustries to address market demands for reliable software products that improve system productivity,time to market, and cost-effective implementation. The JA1003 guidelines address possible taskactivities, methods and techniques through which JA1002 can be implemented. As appropriate,governments and other organizations may also reference these documents.Software has been recognized by SAE G-11 as an important system component that is not adequatelyaddressed at the system level. Software requires interpretation and variations on RMSL methods usedby hardware. In particular, the distinction between hardware and software methods may be difficult todefine with such products as programmable logic devices and Field Programmable Gate Arrays. Thisdocument provides a selection of methods and techniques to implement the simple concept of suppliercustomer-certification authority dialogue and partnership to define, meet, and demonstrate assurance ofsoftware product reliability requirements. JA1003 describes how to structure a Plan in terms of activities,tasks, and methods so as to achieve the requirements of JA1002 and provide demonstrated Caseevidence of reliability achievement.Development of these guidelines has required dedication by a few participants and extended review by awider audience of potential users over an extended period of time. The professionalism of all theseindividuals and the support they received from their companies, governments, and other organizations isgratefully acknowledged.
