10、op an understanding of the customers system/product reliability requirements and constraints (both internal and external) and clearly communicate the developers understanding of the customers requirements. The first objective defines the reliability requirements, assessment criteria, controls, and r
11、esponsibilities of all organizations involved in order to ensure program success. Figure 2 graphically depicts the operation of this Objective. Reliability is the ability/probability of the system/product to perform its intended functions over the expected user and environmental profile for a given
12、period of time. The failure definitions must be coordinated with the customer because not all failures (hardware, software, firmware, process, procedure, or user) are reliability failures but must be assessed for potential corrective action. Reliability requirements are quantifiable and measurable m
13、etrics used to assess the compliance of the contractual requirements. 4.2 Mission and Goals (Informative) The mission of this objective is to assemble a multifunctional team (user, customer, and developer) to 1. understand the customers requirements, failure definitions, user and environmental profi
14、les, and 2. influence the design based on the users needs and constraints.

16、 groups shall collaborate during each phase of the program, perceive and mutually understand specific goals and objectives, and define and develop the system/product reliability requirements using a number of industry tools such as Quality Function Deployment (QFD). Customer-User Communication: The
17、customer community must collaborate with the users to define the desired capabilities for a system/product. This capability definition includes design reliability and operational reliability in the smallest logistics footprint. The logistics footprint is a function of system/products embedded diagno
18、stics and the customers system/product support plan (spares, maintenance, training, and technical manuals). Customer-Developer Communication: The customer must communicate the users desired reliability and performance requirements for the system/product to the developer. The developers engineering o
19、rganizations must analyze the requirements and establish a dialogue with the customer so that the developer can complete a detailed requirements analysis to ensure that the requirements are understood and feasible. The developer shall communicate the acceptance of the requirements or recommend an al
20、ternative to the customer. This communication is necessary to ensure eventual system/product suitability. These communications between the developer and customer should be documented. User/Customer-Developer Communication: The system/product reliability feasibility assessment (i.e., the assessment o
21、f the feasibility of achieving the user/customer requirements) shall be completed to the same level as the customers specification to the developer. System/product engineering and reliability engineering functions shall be responsible for implementing and executing the design-for-reliability methodo
22、logy over the system/products life cycle. The customer will ensure that sufficient funding is available for the developer to provide a system/product that meets requirements when operated and maintained by the user over the system/products life cycle. The goal is to apply the optimum funding profile
23、 for design, development, verification, and deployment at the appropriate time. 4.4 Supporting Information (Normative) The information listed under Input Information is required in order to enable the developer to design, produce, and deliver a system/product that meets requirements and is suitable
24、to the end user. This information may be provided by the customer or may be jointly developed by the customer/user and developer. 4.4.1 Input Information (Normative) The following information is required before a reliable system/product can be designed: Quantitative reliability requirements and rati
25、onale for the system/product. Cost and schedule requirements and funding profile. Known failure modes and mechanisms, if any. Failure Definition and Scoring Criteria, if customer supplied. 13 Copyright Government Electronics & Information Technology Association Provided by IHS under license with GEI
26、A Not for ResaleNo reproduction or networking permitted without license from IHS-,-,-GEIA-STD-0009 User and environmental profile that defines the system/products life cycle (operating and non-operating environments (including storage), expected operating and non-operating times, etc.). For example,
27、 miles traveled, percent terrain type, hours of operation, rounds fired, etc. Other documentation such as performance requirements and specifications, system/product engineering plans, system/product test plans, documentation on operational concepts, maintenance concepts, and logistics support. Rati
28、onale for the reliability requirements should include, as applicable, 1. requirements for availability, maintainability, testability, durability, and system health fined as embedded diagnostics, Built-In Test (BIT), and prognostics), 2. customer/user design constraints (e.g., technology, manpower, t
29、raining, and logistics port), 3. desired maintenance concepts, 4. reliability estimates, support concept, and limitations for similar systems/products, and 5. data on how the system/product will be packaged, handled, shipped, and transported. 4.4.2 Developed Information (Normative) During the course
30、 of designing reliability into a system/product, a considerable amount of information will be developed. In many cases, input information to this objective will be expanded on and updated. The activities in Section 4.5.1 will result in the developer generating this information. The information devel
31、oped shall include: Reliability Program Plan that spans the system/product life cycle and includes, as a minimum, the activities specified in Section 4.5.1, as well as the framework for the Reliability Case and the initial reliability cost, schedule and staffing plan. Conceptual reliability model fo
32、r the system/product and allocations derived from the customers top level requirements to the major subsystems. Initial reliability flow-down requirements to the major subsystem level. Failure definitions and criteria that are integrated with the developers Closed-Loop Failure-Mode Mitigation Proces
33、s. Initial reliability assessment showing that the customers design constraints are understood and the reliability requirements are feasible. Candidate reliability trade studies for available technology or needed technology development to mitigate development and associated risks. Agreed-to definiti
34、ons for new design, Non-Developmental Items (NDI), modified NDI, Customer-Furnished Items (CFI), and Commercial-Off-The-Shelf (COTS) hardware/software. Reliability Requirements Verification Strategy/Plan including a traceability and verification matrix connecting the customers requirements to develo
35、pers requirements. System/product-level user and environmental profile. 4.5 Activities, Methods, and Tools This section is divided into two parts. The first part specifies the normative activities that the developer shall perform. The second part is informative in nature and lists methods and tools
36、that the developer may consider to effectively support the normative activities. 14 Copyright Government Electronics & Information Technology Association Provided by IHS under license with GEIA Not for ResaleNo reproduction or networking permitted without license from IHS-,-,-GEIA-STD-0009 All activ
37、ities, methods and tools used should be evaluated and applied in a manner that adds demonstrated value to the program, at an optimized life cycle cost and utilization of resources, in support of the stated mission and goals of this Objective. 4.5.1 Activities (Normative) 4.5.1.1 Reliability Program
38、Plan (RPP) The developer shall develop a program for designing, manufacturing, and sustaining reliable systems/products. The RPP shall be tailored to each system/product. A RPP should ideally be developed both by the developer (delineating those activities required to meet customer reliability requi
39、rements) and the customer (who provides an expansion of the required activities to include the tasks and customer-supplied resources to support and confirm the attainment of reliability requirements). The developer may identify and include additional activities not identified herein. The RPP is init
40、ially prepared early in the program and is periodically updated and coordinated with the customer. The RPP shall: Plan for the attainment of customer reliability requirements. Provide visibility into the management and organizational structure of those responsible and accountable (both developer and
41、 customer) for the conduct of reliability activities over the entire life cycle. Define all resources (e.g., personnel, funding, tools, and facilities) required to fully implement the reliability program. Include a coordinated schedule for conducting all reliability activities throughout the system/
42、product life-cycle. Include detailed descriptions of all reliability activities, functions, documentation, processes, and strategies required to ensure system/product reliability maturation and management throughout the system/product life cycle. Document the procedures for verifying that planned ac
43、tivities are implemented and for both reviewing and comparing their status and outcomes. Manage potential reliability risks due, for example, to new technologies or testing approaches. Ensure that reliability allocations, monitoring provisions, and inputs that impact reliability (e.g., user and envi
44、ronmental loads) are flowed down to subcontractors and suppliers. Include contingency-planning criteria and decision-making for altering plans and intensifying reliability improvement efforts. Include, at minimum, the normative activities identified throughout this standard. Include, when applicable
45、, additional customer-specified normative activities. The RPP shall address the implementation of all the normative activities identified in Objectives 1 - 4: System/Product Reliability Model and Requirements: Describe 1. the methods and tools that will be used to build and refine the system/product
