5、8 Superseding JA1010 OCT2000 Maintainability Program Standard RATIONALE This Maintainability Program Standard was updated to correct inconsistencies between this document and the Maintainability Program Standard Implementation Guide (JA 1010-1). The changes included updating technical terms, definit
6、ions and editing certain sections. Additions, deletions and corrections deemed necessary by the Maintainability Committee members were incorporated in this revision. FOREWORD In March 1997, the SAE G-11 Reliability, Maintainability, Supportability, and Logistics (RMSL) Division standards section cha
7、rtered a subcommittee to create a maintainability program standard. The subcommittee was formed from a representative cross-section of commercial industries and military (DOD and Government). In response to that charter, this standard has been developed. The subcommittee has endeavored to develop a
8、standard that would reflect current commercial and military practices and meet the objectives of the United States Department of Defense Acquisition reform initiative. This performance-based standard was developed in recognition of todays intense and competitive market demands for world class mainta
9、inability, low cost, and speed to market. This standard relies heavily upon the supplier-customer dialogue, and it intentionally allows suppliers great freedom to uniquely tailor maintainability programs. However, it was recognized that, in addition to the requirements of this standard, guidance for
10、 developing maintainability programs is frequently required. Consequently, the subcommittee has also been chartered to produce a Maintainability Program Standard Implementation Guide, which sets forth current, world class proven maintainability best practices and provides activities and processes th
11、at may be used to satisfy the requirements of this standard. In addition, the Standard and Implementation Guide are intended to become part of a set of comprehensive RMSL program and task standards planned by the G-11 Division to replace selected Military Standards and Specifications. The profession
12、als in the subcommittee gratefully acknowledge the support from their companies and from the many individuals and organizations, who made contributions and provided recommendations to the subcommittee. 1SAE JA1010 Revised AUG2011 Page 2 of 6 1. SCOPE 1.1 Purpose This SAE Standard establishes the req
13、uirement for suppliers to plan a maintainability program that satisfies the following three requirements: The supplier shall ascertain customer requirements. The supplier shall meet customer requirements. The supplier shall assure that customer requirements have been met. 1.2 Applicability This docu
14、ment applies to activities related to the specification, design, development, and assurance of any system (hardware and/or software) product or processes. 1.3 Tailoring This document does not specify the activities, tasks or methods to be included in the program. Rather, the content of each program
15、must be tailored to satisfy customer requirements using the most appropriate means. 2.

18、s to satisfy a maintainability program requirement. 3.2 CUSTOMER The recipient of a product (e.g., the customer may be the purchaser, beneficiary, ultimate consumer or user.) 3.3 LIFE CYCLE A series of stages a product or process passes through during its lifetime, from concept through decommission.
19、 SAE JA1010 Revised AUG2011 Page 3 of 6 3.4 PROCESS A series of activities leading to a desired result. 3.5 PRODUCT Hardware, software or any combination thereof. 3.6 QUALIFICATION Activities that constitute formal evidence the product or process specifications have met customer requirements, includ
20、ing quantitative and qualitative measures. 3.7 MAINTAINABILITY The relative ease and economy of time and resources with which an item can be retained in, or restored to, a specified condition when maintenance is performed by personnel having specified skill levels, using prescribed procedures and re
21、sources at each prescribed level of maintenance and repair. NOTE: In some industries, such as automotive, maintainability is referred to as serviceability. 3.8 REQUIREMENT a. Customer RequirementsThe expressed or inferred needs and wants that a customer desires from a product. b. Product Requirement
22、sAcceptable levels of specific performance parameters for a given set of conditions. c. Program RequirementsThe three requirements identified in 1.1. 3.9 Resources The means available to an organization for developing a product or process including, but not limited to, materials, facilities, personn
23、el, capital, time, equipment, hardware, and software. 3.10 SUPPLIER An organization, either internal or external, that provides a product or system to a customer. 3.11 TASK An assigned piece of work to be accomplished within a specified time. 4. PROGRAM REQUIREMENTS 4.1 The Supplier Shall Ascertain
24、Customer Requirements The maintainability program shall contain documented activities to ensure that customer requirements are fully understood and defined. Customer requirements shall include, but are not limited to, conditions of use, operating environment, maintenance concept, service requirement
25、s, and product specifications. 4.1.1 Establish Supplier-Customer Dialogue A documented supplier-customer dialogue shall be initiated, no later than conceptual design and prior to development of the maintainability program, to establish mutually understood requirements. Where requirements are not kno
26、wn, assumptions of requirements shall be made by the supplier, verified by the customer, and mutually agreed upon. SAE JA1010 Revised AUG2011 Page 4 of 6 4.1.2 Identify Conditions of Use The supplier, with input from the customer, shall identify all relevant product usage information for all stages
27、of its life cycle, operational profile, environment conditions, resources required, and any maintenance and service policies, which are used in determining maintainability requirements. 4.1.3 Define Maintenance and Service The supplier and customer shall mutually agree upon any maintenance and servi
28、ce requirements. 4.1.4 Establish Metrics Metrics, which assesses the ability of the product to meet customer requirements, shall be identified by the supplier and agreed upon by the customer.
