The document reviews architecture options for the timely generation of client files, evaluating four alternatives with option 4 deemed most viable due to its timing and content effectiveness. Concerns highlighted include the need for email notifications, scalability, and capacity issues affecting overall performance. Additionally, development costs and operational requirements were discussed, emphasizing the need for ongoing support and adjustments to maintain management reporting functionality.

- 1. ARCHITECTURE REVIEW CERTIFICATE Date of Issue 07/09/2009 Project / Change Timely Generation of Cleint Files Major Associated Units/ Systems Transaction Integrator (ETL), TMS, Ingenico, EDG ... To be read in conjunction with Logica's proposal - Client File Design v 1.2 Options Evaluated Option 1 Time dependent ETL Parallel Processing Option 2 Horizon Process Modification Option 3 Time dependent DIW Data Load Option 4 Event dependent DIW Data Load Area Rating Option 1 Rating Option 2 Rating Option 3 Rating Option 4 Concerns Reference to meeting quality expectations Need to activate (1) Email Notifications, (2) Time Account functionality. Scalability Contingency and Timing Constraints in face of increasing transactions and data flows Ability to meet major functions / objectives Option 4 is the most viable in terms of timing and content Appearance Not relevant in this case Personnel level required to use/operate the product Not relevant in this case Performance levels - customer expectations Options 1,2 & 3 relatively better contingency compared to Option 4 Capacity Issues, impacting Capacity of the entire landscape, like bandwidth of datalink, utility of TMS, timing of feed from Ingenico need to be discussed separately. Accuracy of data being generated / processed Options 3 & 4 call for manually handling exceptions / ''Suspense Records'' if need be. Data Growth / Data Management High Availability Reliability Due to no-to-little contigency and time limit constraints- options 2, 3 & 4 maynot be suitable. Development cost 40K ???? ???? 10K Indicated cost of development and maintenance for Option 1 & 2 prohibitive Effort & Elapsed Time to build, test, depoly High ???? ???? Low Security No option has relative advantage or disadvantage as files are still routed through EDG vide Tivoli scheduled jobs. Ease of use / Change in User Behaviour Not relevant in this case Impact on Management Reporting on functionality being deployed/proposed Subsequent batch processing to do with data processing / preparation for Report Generation may need adjustment Overall Architecture Event based dependency (i.e. completion of TMS processing ) prior to generation of Client Files makes Option 4 the most viable option. Ongoing Support & Operational availability Recommended Option(s) Option 1 Option 4 Issued By Strategy & Architecture / Ajay Uppal
