Scenario: Eight Twelve
Eight Twelve has retail outlets throughout North America. An Enterprise Architecture practice
already exists in Eight Twelve. Now the CEO and CIO decide that they want to use TOGAF9 to rearchitect their Enterprise Architecture to cater to the changing strategies of Eight Twelve to better
respond to the changes in the economic and technology environments.
Some of the key issues which need to be addressed in this re-architecting work are:
1. Since Eight Twelve’s retail chain operate 24 hours a day and are expanding to South America and
Europe, the retail chain business ecosystem should be able to withstand any unforeseen disruptions
which might affect the chain’s day to day operations. This is highly critical to ensure high levels of
customer satisfaction and thus maintaining and enhancing Eight Twelve’s revenue chain.
2. Dependency between the application components, which are the nerve centers to Eight Twelve’s
sophisticated range of services both external and internal, and the application platform and
technology infrastructure should be minimal. This would facilitate scalability and ease of
enhancement of the service offerings.
3. Eight Twelve uses the ARTS Data Model and the quality of data is of utmost importance for its
operation.
4. Users of the Enterprise Information ecosystem should have an environment which is able to cater
to their needs without any undue delays.
