Description (English):

ISO/TS 18667:2018 applies to the design, development, fabrication, test, and operation of commercial, civil, and military space and ground control systems, sites/facilities, services, equipment, and computer software. Criteria is provided for rating the capability of the entire SD&QA programme or an individual SD&QA process to identify, assess, and eliminate or mitigate risks that threaten safety or mission success. The predefined capability rating criteria define the sequence of activities necessary to achieve a measurable improvement in the effectiveness of SD&QA risk management by implementing it in stages. Organizations can evaluate their existing SD&QA programme against the criteria in this document to identify the activities that need to be added, deleted, or modified to achieve the desired technical risk management effort. The phrase "desired technical risk management effort" means the activities and resources used to identify, assess, and eliminate or mitigate technical risks are commensurate with the product's unit-value/criticality and systems engineering life cycle data content/maturity.

Abstract

Overview

ISO/TS 18667:2018 - "Space systems - Capability‑based Safety, Dependability, and Quality Assurance (SD&QA) programme management" - provides guidance and capability‑rating criteria for planning, implementing, assessing, and improving SD&QA programmes across the life cycle of space systems. It applies to the design, development, fabrication, test, and operation of commercial, civil, and military space and ground control systems, sites/facilities, services, equipment, and computer software. The technical specification defines staged capability levels so organizations can scale SD&QA effort to product unit‑value/criticality and the maturity of systems engineering data.

Key Topics and Requirements

Capability‑based approach: Predefined criteria (Annex B) to rate the capability of an entire SD&QA programme or individual SD&QA processes and to plan staged improvements.
Scope of application: Covers safety, dependability, and quality assurance for space and ground control systems and associated software, facilities, and services.
Programme governance: Authorize SD&QA programmes, assign qualified managers/engineers/technicians, and define policy, objectives, and principles.
Requirements flow‑down: Identify and flow down essential SD&QA requirements; provide disposition criteria for conflicting requirements.
Process selection and phasing: Select SD&QA processes based on product criticality and define implementation phasing aligned with systems engineering life‑cycle milestones.
Risk management integration: Integrate SD&QA with programme‑wide technical risk management - identification, qualitative/quantitative likelihood assessment, mitigation assessment, tracking and reporting (single risk matrix format).
Engineering and verification methods: Failure mode identification, maturity assessment of input data and assumptions, structured reviews, self‑inspections, and verification that SD&QA requirements are met.
Continuous improvement: Capture and apply lessons learned, maintain SD&QA databases, and use capability ratings to plan changes in activities, resources, or processes.
Supporting material: Annex A (fundamental processes), Annex C (definitions), Annex D (safety/mission‑critical checklist), and normative references to related ISO space programme standards.

Applications and Who Uses It

Aerospace prime contractors and subsystem suppliers implementing SD&QA across development, production, test, launch, and operations.
Space agencies and government programmes setting programme‑level assurance expectations for contractors.
Programme and project managers aligning SD&QA work to product criticality and life‑cycle maturity.
Systems engineers, safety and dependability engineers, QA leads, and certification authorities who need structured, scalable methods to manage technical risk and verify compliance.

Related Standards

ISO 10794, ISO 10795, ISO 14300‑2, ISO 14620‑1, ISO 17666, ISO 23460, ISO 27025, ISO 9000 - referenced normative documents that address programme management, vocabulary, system safety, risk management, dependability, and QA concepts relevant to ISO/TS 18667:2018.

Keywords: ISO/TS 18667:2018, space systems, SD&QA, safety, dependability, quality assurance, capability‑based, risk management, programme management.
