Which term describes the smallest deliverable unit of sources for installation on an instance?

The term that describes the smallest deliverable unit of sources for installation on an instance is "Change."

In the context of the Avaloq Integrated Customization Environment (ICE), a Change typically refers to a specific modification or enhancement in the software that can be packaged and deployed to different instances. It represents a set of updates that might include new features, bug fixes, or adjustments to existing functionality. This modular approach allows for granular updates, ensuring that implementations can be correctly managed and deployed without affecting the overall system negatively.

Other terms like Task, Solution, and Source do have distinct meanings within the Avaloq framework, but they do not specifically identify the smallest unit for installation. A Task often refers to specific actions or requests that are part of a larger Change, while a Solution could encompass a broader set of Changes and components offering complete functionality. Source typically refers to the original code or resources needed to create Changes but does not denote the unit of deliverable modification itself. Therefore, "Change" is the most accurate term for this context.
