The Preliminary and Vision Phase have been completed.
As such very few architectural artifacts exist and the target architecture as of now is not very clear. As the Lead Architect how would you guide your team of architects for the Business Architecture definition?
A. In the first iteration start with the definition of the Target Business Architecture using a Top down Approach.
Then keep on iterating in Phase B till the Target Business Architecture is refined before going to Phase C and Phase D. After Phase C and Phase D are over,
iterate again to Phase B and define the baseline Business Architecture, analyze the gaps finalize the Architecture Definitions documents and proceed to Phase C and Phase D.
B. In the first iteration start with the definition of the Baseline Business Architecture using a Top Down approach. Define the Architecture Definition document after
analyzing the impacts and reviewing with the stakeholders. Then proceed to Phase C and Phase D. In the next iteration finalize the Target Business Architecture
and proceed to Phase C and Phase D.
C. In the first iteration start with the definition of the Baseline Business Architecture using a Bottom Up approach. Define the Architecture Definition document after
analyzing the impacts and reviewing with the stakeholders’.
Proceed to Phase C and Phase D. In the next iteration finalize the Target Business Architecture, determine the gaps and the roadmap, and the impact and
update the Architecture Definition document. after analyzing the impacts and reviewing with the stakeholders. Then proceed with the iteration.

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?
