Configuration of and changes to firmware are controlled throughout the asset lifecycle

Statement

Configuration of and changes to firmware are controlled throughout the asset lifecycle

Context and Guidance: Through the lifecycle of an asset, it may be necessary to change or update the firmware for reasons such as enabling specific functionality or improving performance. Where possible, the organisation should carefully test changes to firmware prior to deployment, because these changes could also cause unanticipated behavior of the asset or other connected assets.

Related Practices • Progression: This practice is part of a practice progression. Practice progressions are groups of related practices that represent increasingly complete or more advanced implementations of an activity. The practices in this progression include: ARCHITECTURE-3e, ARCHITECTURE-3f, ARCHITECTURE-3l.
