Overview
ISO 22893:2022 - Space systems - Software product assurance (SPA) defines a uniform set of software product assurance requirements for space systems. It specifies the processes and work products to be applied across the entire software life cycle, from project conception through maintenance and retirement. The standard targets the space software segment (on‑board/flight software) and critical ground software that interfaces directly with space assets, and integrates software safety, dependability and quality assurance into a single SPA management framework.
Keywords: ISO 22893:2022, space systems, software product assurance, software safety, software quality assurance
Key topics and requirements
- Life‑cycle coverage: SPA activities are required throughout requirements, design, construction, testing, delivery, operation and maintenance phases.
- Management and planning: SPA planning and control, risk management, supplier selection and procurement oversight are defined as mandatory elements.
- Process assurance: Monitoring and supporting software engineering processes (system and software requirements analysis, architecture, detailed design, coding, testing, delivery/acceptance).
- Support processes: Requirements for documentation, safety & security analysis, critical item handling, configuration management, metrics, verification, validation, reviews, audits and problem resolution.
- Organizational processes: Guidance on SPA‑related management processes, infrastructure, training, reuse, evaluation of automatic code generation and model‑based software engineering.
- Independent assurance: SPA should be performed (or supervised) by independent assurance personnel to ensure compliance with project plans and product assurance objectives.
- Quality, safety and security integration: SPA integrates safety, dependability and quality activities to ensure software performs safely and reliably in its operational environment.

Practical applications and users
ISO 22893:2022 is applicable to organizations involved in the development, maintenance or operation of space software and critical ground systems. Typical users include:
- Space agencies and program/product assurance teams
- Prime contractors and subcontractors developing on‑board or ground control software
- Systems engineers, software engineers and QA/SQA managers
- Procurement and supplier management personnel
- Independent assurance auditors and certification bodies
Practical uses:
- Establish SPA plans and tailoring for projects
- Define supplier qualifications and monitoring criteria
- Implement configuration, verification and validation controls
- Integrate safety and security analyses into software lifecycle activities
