Overview - What ISO 21886:2019 covers
ISO 21886:2019 - Space systems - Configuration management specifies the contents, methods and requirements for configuration management (CM) applied to space projects. It defines responsibilities and authorities for all parties involved and is intended for use from the mission analysis phase through disposal. The standard helps organizations maintain a consistent record of a product’s functional and physical characteristics relative to design and operational requirements.
Key topics and technical requirements
ISO 21886:2019 organizes CM into the core disciplines that a space program needs:
- Configuration management planning
- Development of a configuration management plan (CM plan) and definition of CM interfaces.
- Configuration identification
- Definition of configuration items (CI), product trees, identification marking, configuration documents and configuration baselines.
- Configuration control
- Formal change control processes including change classification (major/minor), procedures, and handling of deviations/waivers.
- Interface control
- Managing and controlling interfaces between subsystems and suppliers.
- Configuration status accounting
- Recording and reporting the status of configuration items and changes.
- Configuration verification and audit
- Verification that product configuration matches its definition and performance, plus functional and physical configuration audits.
- Configuration Control Board (CCB)
- Establishment of a CCB with delegated decision-making authority to review and approve changes.
These topics align with normative references cited in the document, including ISO 14300‑1:2011, ISO 10007, and ISO 10795.
Practical applications - who uses ISO 21886:2019
ISO 21886:2019 is intended for organizations and roles involved in space system development, production and operations:
- Space programme and project managers
- Systems engineers and configuration managers
- Suppliers and subcontractors in the space supply chain
- Quality assurance and contract managers
- CCB members and technical authorities
Use cases include establishing CM plans, controlling hardware/software changes, auditing spacecraft configuration at milestones, and maintaining traceability from requirements to delivered product.
