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
