# 1 AMI Enterprise Task Force of the Utility AMI Working Group SRS Team Status Report (Palo Alto, Jan. 09) Joe Zhou

# 2 SRS Team Status SRS team status since the Knoxville meeting: –Developed first complete draft of the Logical Components and Functions Model –Supported AMI-ENT service definition team activities including the CMS-AEP collaboration meeting –Started to develop the first draft of the SRS document Guiding Principles Reference Architecture Requirements –Goal is to make the first draft available for reviews by the March meeting.

AMI-ENT SRS seeks to define a complete reference model that includes all logical functional components within and outside utility enterprise that are needed to deliver the AMI specific business functions.

# 6 Why the AMI-ENT Reference Model Because the current IEC reference model is limited to only basic metering related functions. Because the future use case analysis and the services being defined needed a stable reference model to be more consistent and reusable across implementations. Because it could serve as the vehicle to manage the scope and priorities of use case and services to be delivered. Because it could provide best practice architecture recommendations for those implementations that may want to leverage outcomes AMI-ENT effort.
