Patterns & Co. is introducing a Commercial Off-the-Shelf (COTS) Market Analytics solution in order to
improve its new delivery service.
Patterns & Co. has a mature enterprise architecture capability and the CIO is the sponsor of the
enterprise architecture team. The business vision and requirements for the new system are defined.
It includes a detailed business process analysis. The supplier has proposed a solution but the
Architecture Board identified some of the project requirements not consistent with the adopted
infrastructure standards. The CIO considered the risks and approved the implementation.
The CIO has asked the EA team to execute the Phase G ensuring that the system performance KPIs
are respected, the project remains within budget and security guidelines are met.
Refer to the scenario above As Lead Enterprise Architect you have to recommend a plan to
implement the CIO decision. Choose the best answer according to TOGAF 9.
Choose one of the following answers
A.
You ask the supplier to modify the web server hardware and software components so they can
meet the current infrastructure standards. You advise to execute a proof of concept to anticipate
any coding issue. Then, after the agreement with the development leads for supporting the
development, you will provide the project plan to the project manager and develop an Architecture
Contract. A set of frequent operational reviews to monitor the solution’s performance is then
scheduled after the implementation is completed.
B.
You recommend the co-existence of a second web server standard and modify the company
Standards Information Base adding this new technology.You ask the project architects to create an
Architecture Contract with the development teams. You identify the need of a performance testing
and a compliance review You agree with the business on SLA and delivery dates. You identify reusable procedures and objects.
C.
You eliminate the non-standard web server from the solution as recommended by the
Architecture Board. You create a revised plan and Architecture Contract for the development
stressing the re-use of standard technologies. You share the budget implication of this solution with
a finance committee and inform the CIO of the long term cost benefits of this choice. You define
periodical project management meetings to monitor compliance.
D.
You execute a risk analysis and set deliverables and timing requirements with the development
team. You implement a detailed impact analysis of the chosen solution. You create an Architecture
Contract and ask for the CIO’s approval before implementing it. You test the solution just prior to
implementation and deliver the project artifacts and store after the completion of the
implementation.
Best answer is B
CIO considered the risk and approved the implementation. This eliminates A and C. B can be second best, but it miss updating standards to adopt new solution.

Option B –> As SIB is updated in this phase.

I would say option A

Generally, it’s impossible to change web server hardware and software components for a Commercial Off-the-Shelf package software

Moreover it should have been done in phase E when looking at the SBB.
Discussions with the supplier (eventually POC) to change his solution.

B even though it sounds good, I still doubt why would they modify SIB with this even when Architecture Board rejected it. I referred SIB in spec and it doesnt mention anything closer to that in terms of updating SIB.

But Answer D is also suffering from multiple issues:
1. Create an Architecture Contract and ask for the CIO’s approval –> CIO is not the approver its the joint agreements between development partners and sponsors.
2. Test the solution just prior to implementation –> Architect testing it doesn’t make sense.
So out of B and D, B is much better.
