Phase 4B—Configuration
System configuration, as it relates to the SDLC, consists of
defining, tracking and controlling changes in a purchased system
to meet the needs of the business. For ERF systems, the task
often involves the modification of configuration tables as well as
some development, primarily to ensure that the ERP system is
integrated into the existing IT architecture. System configuration
is supported by the change management policies and processes,
which define;
• Roles and responsibilities
• Classification and prioritization of ail changes based on
business risk
• Assessment of impact
♦ Authorization and approval of all changes by the business
process owners and IT
• Tracking and status of changes
• Impact on data integrity (e.g., all changes to data files being
made under system and application control rather than by direct
user intervention)
