UC-4.2 Managing System Configuration
Summary
Number	UC-4.2
Name	Managing System Configuration
Context	UC-4 Administration
Sub-Use Cases	None
Overview	Manage System Configuration monitors and reconfigures the functionality of the entire archive system through interactions with Data Management, Archival Storage, Preservation Planning and other functions within Administration. It audits system operations, system performance, and system usage.
Actors	Archival Information Update Manage System Configuration Archival Storage>Manage Storage Hierarchy Data Management>Generate Report Preservation Planning>Develop Packaging Designs and Migration Plans Preservation Planning>Develop Preservation Strategies and Standards
Description
Preconditions	None
Trigger	None - this is a continuous process
Successful outcome	Archives system configured optimally

Citations	OAIS Page 4-11, s. 4.1.1.5 "The Manage System Configuration function provides system engineering for the archive system to continuously monitor the functionality of the entire archive system and systematically control changes to the configuration. This function maintains integrity and tractability of the configuration during all phases of the system life cycle. It also audits system operations, system performance, and system usage. It sends report requests for system information to Data Management and receives reports; it receives operational statistics from Archival Storage. It summarizes those reports and periodically provides OAIS performance information and archive holding inventory reports to Preservation Planning. It sends performance information to Establish Standards and Policies. It receives migration packages from Preservation Planning. It receives system evolution policies from the Establish Standards and Procedures function. Based on these inputs it develops and implements plans for system evolution. It sends change requests, procedures and tools to Archive Information Update [sic]."

Notes
	The diagram does not indicate that Manage System Configuration sends performance information (or anything at all) to Establish Standards and Policies, but this is clear from the text. This might need to be broken down into multiple use cases; suggestions: Manage System Configuration Manage System Evolution Manage Migration
