• Understand the IAA services, Service Level Agreements (SLAs), and cost structures and develop relevant metrics to be able to monitor provider performance, and cost structures and develop relevant metrics to be able to monitor provider performance
• Set up the Service Level Agreement to foster a mutually beneficial relationship. Make sure that both the provider and the customer are clear on expectations of success defined in Activity 1.6
• Leverage an agile approach in the migration and consider phasing the implementation to provide for quick wins
