AMIT Business Strategic Realignment August 31, 2010

Business Strategic Realignment 2 Purpose It has been almost three years since the development of the AMIT projects and their corresponding requirements. During that time there have been changes in both the Texas Market business processes and technologies including development of solutions such as Smart Meter Texas and implementation of 15 minute interval data. Therefore it is an opportune time to strategically realign AMIT projects and requirements to be the most effective based on the critical needs of the newly evolved Texas Market. Also, it is an opportune time to refocus efforts into areas of most impact, renew activities and tasks that support driving to completion those efforts, and reset expectations for delivery priorities, timeline, and dependencies.

Business Strategic Realignment 3 Objectives Based on recent lessons learned, enhanced knowledge from experience, current business and technology environments of the evolving Texas Market: Realign the AMIT business processes based on the current highest priority and most critical needs Identify initiatives to effectively and efficiently deliver the realigned business processes Roadmap the identified processes, functions / initiatives for clear understanding of delivery ranking, timelines and dependencies Refocus efforts based on the re-prioritization and realignment Gain renewed consensus, buy in, participation and enthusiasm from AMIT Market participants
