B.3.9.2
Example Work Products
• ongoing database or repository containing identified needs, process improvements, and product improvements;
• clearly described processes, methods, and avenues for getting identified needs into a database or repository;
• identified needs for process improvement;
• identified needs for product improvement;
• trouble reports.
B.3.9.3
Notes
This base practice is critical to the effective use of systems engineering in the production, operations, and maintenance
life-cycle phases.
Needs for corrective action are detected in this base practice. Corrective actions are directed in the Monitor and Control
Technical Effort process area (PA11).
Trouble reports also flow into this base practice from the Verify and Validate System process area (PA11).
B.4 PA13 - Manage Configurations
B.4.1
B.4.1.1
Process Area
Security Considerations
In BP.13.02 the determination of the level of configuration units identified for a system/project should consider the level
of detail required by the assurance objectives in PA06 Build Assurance Argument.
Manage Configurations provides evidence to PA06 Build Assurance Argument. Also, the configuration management
system selected should itself be managed according to PA08 Administer Security Controls.
B.4.1.2
Summary Description
The purpose of Manage Configurations is to maintain data on and status of identified configuration units, and to analyse
and control changes to the system and its configuration units. Managing the system configuration involves providing
accurate and current configuration data and status to developers and customers.
This process area is applicable to all work products that are placed under configuration management. An example set of
work products that may be placed under configuration management could include hardware and software configuration
items, design rationale, requirements, product data files, or trade studies.
B.4.1.3
Goals
• Control over work product configurations is maintained.
B.4.1.4
