1、在系统工程中建立与维护需求跟踪矩阵(RTM)的技术EstablishandMaintainRequirementsTraceabilityMatrix(RTM)TechnologyIntheSystemsEngineering为了确保工作产品与需求保持一致，需要建立起二者之间的追溯关系。在系统工程中，一般可以通过建立与维护需求跟踪矩阵的技术方法来管理需求之间的“垂向”与“水平向”关系。建立与维护需求与工作产品之间的双向可追溯性，能够确保需求到产品实现的无遗漏和减小偏离，并有助于变更影响分析、覆盖率分析、来源分析、质量分析

5、技术方法。当需求被有效管理时，需求管理能够建立起原始客户需求与底层组件需求的双向关系，各层需求与需求之间的双向关系，各层需求与实现的双向关系，各层需求与验证的双向关系，以及需求的责任分配的双向关系。RTM在需求开发和需求管理中起着纽带和桥梁的作用。RequirementsTraceabilityMatrix(hereinafterreferredtoastheRTM)referstothesystemengineeringtobuildrequirementanddependentrequirement,design,i
