Dependability is a collective term used to describe the availability performance and its influencing factors: reliability performance, maintainability performance, and maintenance support perfomance.
Dependability is used only for general desciptions in non-quantitative terms.
Source: IEC 60050, 191-02-03.
根據IEC 60300-2_2004,可恃性管理指引(Guideline for Dependability Management)之說明,可恃性管理的架構完全與ISO 9000品質管理相調和,包括:
第4章 可恃性管理系統(dependability management system)
第5章 管理責任(management responsibility)
第6章 資源管理(resources management)
第7章 產品實現(product realization)
第8章 量測分析與改善(measurement, analysis, and improvement)
