The CIO has evaluated and decided to go in for TOGAF9 and adapt it to his enterprise requirements.
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.
  • D. In the first iteration start with the definition of the Target Business Architecture using a Top Down 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 Baseline Business Architecture, determine the gaps and the roadmap, and the impact and update the Architecture Definition document.

C is right -> current state not clear not many artefacts/docs available then have to do bottom up (much like reverse engineering) -> target not clear so have to do baseline and define transition to target ->

Selected Answer: C
https://pubs.opengroup.org/architecture/togaf9-doc/arch/index.html 18.4 Baseline First: in this style, an assessment of the baseline landscape is used to identify problem areas and improvement opportunities. This process is most suitable when the baseline is complex, not clearly understood, or agreed upon. Based on that, I vote for C

Answer C is correct. In the Baseline Description, however, the analysis of the current state often has to be done bottom-up, particularly where little or no existing architecture assets exist.In such a case, the architect simply has to document the working assumptions about high-level architecture. https://pubs.opengroup.org/architecture/togaf8-doc/arch/chap06.html

The given scenario want to put EA capability in place. Hence, Top-down <-- Strategic, top-down directed change to enhance or create new capability (capital) Baseline First without Transition Planning <-- "Supporting Business Strategy" engagement. So Answer is B

I'm sure it's either B or C (since baseline first), but deciding its a top-down or a bottom-up is confusing. After reading the discussions, I'd go with C

B. Baseline first as they are starting from scratch, then bottom up approach as they are starting from the bottom.

A should be correct. The top-down approach means that you start with the business requirements (the B layer) and fully decide the problems your business needs to solve before thinking about the technology to solve those problems.

The scenario is "very few architectural artifacts" and "target architecture not very clear". In this case you have little stuff to do it from top-down (e.g., the senior management might not even know exactly how many applications are running in production, not to say which applications should be replaced or retired), so a bottom-up approach should be used. And when target architecture is not clear, TOGAF's recommendation is go for Baseline first approach.

you are right in practice but what about 15.5.1 chapter (9.2) * Strategic, top-down directed change to enhance or create new capability (capital) For this reason I would go with baseline, top-down approach >> answer B But I have not seen this answer it in any example test?! so I am missing something
