Question #: 13

Topic #: 2

Please read this scenario prior to answering the question
You are employed as an Enterprise Architect within a multinational company. The
company has been very successful and has been buying companies around the
world. This has led to a growing number of manufacturing divisions in various
locations with a complex supply chain.
The top management recently expressed concerns about the company's effectiveness
because of its multiple data centers and duplicate applications. The EA team has
been working on a project to solve this issue. An analysis shows that supply chain
issues have led to not enough products being produced to meet all the customer
demand.
A strategic architecture has been defined to help meet customer demand and manage
the supply chain more effectively. The strategic architecture involves combining
different Enterprise Resource Planning (ERP) applications that are currently used
separately in the company's production sites.
Each division has finished the Architecture Definition documentation to address their
own specific manufacturing needs. The Enterprise Architects have agreed an overall
strategy for the migration. They have defined a set of work packages that address the
gaps found. They have defined the intermediate architectural states between the
Baseline and Target architecture to add a new ERP environment into the company.
Because of the risks posed by this change from the current environment, the
architects have recommended that a phased approach should be taken to implement
the target architecture with several stages of change. They have created a draft
roadmap with the implementation process estimated to take over two years.
The company has an established Enterprise Architecture (EA) practice and follows the
TOGAF Architecture Development Method. The company also uses various
management frameworks such as business planning, project/portfolio management,
and operations management. The EA program is sponsored by the Chief Information
Officer (CIO). In your role as an Enterprise Architect within the EA team, you work
closely with the important stakeholders from the various divisions within the company.
Refer to the scenario
You have been assigned to plan the next steps for the migration. Which approach will
you choose?
Based on the TOGAF standard which of the following is the best answer?

You finalize the Architecture Definition documentation with updates to reflect

the implementation approach. You ensure that Implementation and Migration

Plan is consistent with the chosen approach. You identify the resources

needed to undertake the development projects. You would then produce an

Implementation Governance Model to manage the lessons learned before

finishing the plan. You ensure that the lessons

You estimate the business value for each project by applying the Business

You will focus on project selection. You make sure that the Implementation and

Migration plan aligns with the other management frameworks in use in the

company. Next, you assign a value to each work package, taking into account

the resources available and how they fit into the overall strategy. Using these

work packages, you estimate resource requirements and timings. You then

You conduct a series of Compliance Assessments to check that the

achieved. If the targets are not met, you would the

Explanation

At this stage in the scenario:

Astrategic architecturehas been completed.

All divisions have completed theirArchitecture Definition Documents.

Work packageshave been defined.

Transition Architecturesbetween Baseline and Target are already identified.

Adraft roadmapexists for a multi-year phased migration.

You are now asked toplan the next steps for the migration, which aligns exactly withTOGAF ADM Phase F: Implementation and Migration Planning.

In Phase F, TOGAF prescribes the following key activities:

Evaluate and prioritize projects and work packages

Determine business value, cost, risk, dependencies

Confirm Transition Architectures and sequencing

Update and finalize the Implementation & Migration Plan

OptionBis the ONLY answer that correctly follows these required TOGAF steps.

✔Why Option B is correct

Option B states:

“Estimate the business value for each project by applying the Business Value Assessment Technique … to prioritize the migration projects.”✔This is a TOGAF-recommended technique specifically for Phase F to evaluate and prioritize transformations using value, risk, and ROI.

“Confirm and plan a series of Transition Architecture phases … using a table of Architecture Definition Increments.”✔Exactly aligned with TOGAF:

Transition Architectures were identified earlier.

In Phase F, they must beconfirmed, sequenced, and documented.

“Update the Implementation and Migration Plan.”✔This is the required output of ADM Phase F.✔At this point, the plan must be validated and finalized based on value and prioritization.

Thus,Option Bdirectly matches TOGAF’s prescribed migration planning process.

✘Why the other options are incorrect

A – Incorrect

Suggests finalizing Architecture Definition documentation—this was already completed by each division.

Introduces an “Implementation Governance Model,” which is not a TOGAF artifact at this stage.

Focuses on lessons learned BEFORE execution, which is not appropriate for migration planning.

C – Incorrect

Focuses only on project selection and resource assignment.

Does not use TOGAF techniques for value/risk evaluation.

Does not reference Transition Architectures, which are central in the scenario.

Oversimplifies Implementation & Migration Planning to resource scheduling.

D – Incorrect

Compliance Assessments occur DURING execution, notbeforemigration planning.

At this stage, no implementation has started, so compliance reviews are premature.

Adjusting performance requirements now has no alignment with TOGAF’s ADM sequence.
