Business
Case
• Review the business case for the proposed technical solution
Design Completion
• Review the completed detail design for consistency with IT principles and technology standards
Design Chang
e Reqest
• Assess design change request to ensure that it is consistent with IT principles and technology standards
Implementa
tion
• Ensure that the design produced is consistent with proposed architecture
