City of Pleasanton Consulting Services - AMI Procurement and Program Management 13 | P a g e project data quality performance. Our data integrity tool can also be used to help identify synchronization issues that may occur across numerous production systems. Diameter’s Data Quality Protection solution enhances data integrity, streamline operations, and offers actionable insights, ensuring efficient and accurate AMI system functionality. Installation Oversight Through the course of the program, there will be different barriers to replacing the meter or upgrading the Pleasanton residences and businesses to AMI technology. Diameter will manage all issues identified and ensure that the installation contractor takes the appropriate actions as outlined in the operating procedures approved during the Startup subphase. This includes emergency work allowances and pre- installation approvals where additional time, effort or plumbing may be required to upgrade the water meter. In these cases, the additional work can only be performed and invoiced with formal approval from Pleasanton. The installation contractor will also run into issues preventing them from completing the work required. Installation issues will be tracked as “Tasks”. Some examples of common Tasks include location of the meter box, meter box inaccessible, the valve not functioning correctly, etc. Diameter will track these tasks to ensure they are assigned to the appropriate parties and resolved in a timely manner. Diameter will also support Pleasanton with their Compliance Program. Customers who do not respond to requests to book an appointment or who reject the AMI upgrade outright will be subjected to the compliance process, which will leverage new or existing by-laws to encourage them to participate in the program and thus achieve the highest installation rate possible. It is critical for the Pleasanton and Diameter team to set up a reporting structure that allows for validation that all contractual contacts have been completed. First, to ensure that the Installation Vendor has met their contractual requirements but also that Pleasanton can have confidence in the consistency amongst customers before moving to enforce compliance with the program. 1.3.7. POC Success Management Success management is integral to Diameter’s Proof of Concept approach as it ensures the achievement of POC objectives. We recognize that success hinges not only on the implementation of the AMI solution but also on effective user adoption and satisfaction. Final User Acceptance Testing (F-UAT) plays a pivotal role in this process by serving as the final checkpoint before the Installation and Deployment subphase begins, validating that the solution meets user requirements and business needs. By meticulously planning and executing F-UAT, Diameter mitigates risks associated with system failures and ensures that the solution is aligned with the District’s expectations. Moreover, F-UAT fosters stakeholder engagement and collaboration, empowering users to take ownership of the solution and facilitating a smoother transition. Final User Acceptance Test (F-UAT) Final User Acceptance Testing (F-UAT): F-UAT serves as the final checkpoint before full Installation and Deployment. Diameter’s F-UAT plan ensures that all business processes are working properly in the production environment. This includes all processes from meter installation to asset management system updates and customer billing using AMI collected reads. F-UAT will also validate that compliance, task management, invoicing and area management process are also executed as expected allowing for adjustments to be made as needed prior to wide scale deployment. This deliverable will focus on the AMI system using AMI provided MDM and occurs at the end of POC. F-UAT Design includes a list of use cases, expected results, a tracking sheet, scheduling and sequencing the use cases (development plus one review and revision). F-UAT Support includes assisting with running use cases, working with the District to validate the results, a maximum number of use cases of 50, document failures and working with contractor to resolve errors; assumes maximum of one retest cycle for failed test cases.
