Question 32

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 re-architect 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.

Which one of the following set of Architecture Principles do you feel is the most appropriate for these guidelines stated above for the TOGAF 9 architecting work which Eight Twelve is embarking on?

    Correct Answer: D

    To address the key issues for re-architecting Eight Twelve's Enterprise Architecture using TOGAF 9, the most appropriate set of Architecture Principles is: 1) Business Continuity to ensure the ecosystem can withstand any unforeseen disruptions and maintain high levels of customer satisfaction and revenue. 2) Data Trustee to ensure the quality of data, which is of utmost importance for the operation. 3) Technology Independence to minimize the dependency between application components and the application platform and technology infrastructure, facilitating scalability and ease of enhancement of service offerings. 4) Responsive Change Management to ensure the environment caters to user needs without undue delays.

Discussion
SVGNROption: D

"ecosystem should be able to withstand any unforeseen disruptions which might affect the chain's day to day operations" - This is synonymous with Business Continuity.
