scope:

This part of ISO/IEC 15026 gives guidance and recommendations for conducting selected processes, activities and tasks for systems and software products requiring assurance claims for properties selected for special attention, called critical properties. This part of ISO/IEC 15026 specifies a property-independent list of processes, activities and tasks to achieve the claim and show the achievement of the claim. This part of ISO/IEC 15026 establishes the processes, activities, tasks, guidance and recommendations in the context of a defined life cycle model and set of life cycle processes for system and/or software life cycle management.

NOTE The stakeholders determine which of the system or software properties are selected for special attention and require assurance claims. This part of ISO/IEC 15026 uses the term "critical" to distinguish those properties from other requirements.
