Question 1

Which approach to modeling business value is designed to create and end-to-end perspective of value from the customer's perspective?

AValue chains

BValue streams

CLean value streams

DValue networks

Answer : B

A value stream is an approach to modeling business value that focuses on the end-to-end sequence of activities that an organization performs to deliver a product or service to the customer. This perspective is designed to help organizations understand the full lifecycle of value creation, from the initial customer demand to the final delivery of value. It provides a holistic view of the flow of value through the organization and is instrumental in identifying areas of waste and opportunities for improvement to enhance the overall customer experience. Value streams help in visualizing and optimizing the steps necessary to effect change in the business processes and systems that create value for the customers.

Question 2

Consider the following chart:

Which important concept for Enterprise Architecture Practitioners does it illustrate?

AADM phases must be run in a sequenced approach to produce the Architecture

BAn Enterprise Architecture must be developed in phases with a limited fixed duration.

CADM phases must be run simultaneously until the relevant information has been produced

DEnterprise Architects must use Gantt charts to communicate with Stakeholders.

Answer : A

The chart depicted is a Gantt chart, which typically represents the schedule for project activities. In the context of TOGAF's ADM, it is used to illustrate the sequence and interdependencies of tasks across different phases of architecture development. The ADM is an iterative cycle that includes various phases, from the preliminary phase, through architecture vision, business, information systems, and technology architectures, to opportunities and solutions, migration planning, implementation governance, and architecture change management. Each phase must be conducted in a sequence to ensure that the outputs of one phase feed into the next, thereby producing a coherent and structured architecture.

Question 3

Consider the diagram of an architecture development cycle.

Which description matches the phase of the ADM labeled as item 2?

AConducts Implementation planning for the architecture defined in previous phases

BProvides architectural oversight for the implementation

COperates the process of managing architecture requirements

DEstablishes procedures for managing change to the new architecture

Answer : B

The Architecture Development Method (ADM) is the core process of TOGAF which outlines a method for developing and managing the lifecycle of enterprise architecture. Considering the phases of the ADM, the item labeled as '2' in the provided architecture development cycle diagram likely corresponds to the 'Architecture Change Management' phase, which is responsible for providing ongoing architectural oversight and guidance to ensure that the implementation remains aligned with the architecture defined in the previous phases. This includes managing changes to the architecture in a controlled manner as the implementation progresses and ensuring that the architecture continues to meet the business needs.

Question 4

Which of the following best summarizes the purpose of Enterprise Architecture?

ATaking major improvement decisions.

BControlling the bigger changes.

CGuiding effective change.

DGoverning the Stakeholders.

Answer : C

The purpose of Enterprise Architecture, within the context of TOGAF, is to establish a clear and comprehensive blueprint for how an organization can effectively achieve its current and future objectives through a structured approach. Enterprise Architecture guides effective change by providing a long-term view of the organization's processes, systems, and technologies so that individual projects can build capabilities that fit into a cohesive whole. It helps to ensure that IT investments are aligned with business goals, supports the management of complex IT landscapes, and provides a systematic approach for the adoption of emerging technologies. Essentially, it acts as a strategic framework that facilitates the translation of business vision and strategy into effective enterprise change.

Question 5

Explain how business models can be used according to the TOGAF standard.

ATo estimate resource requirements for the definition of the architecture.

BTo plan the Implementation activities for the architecture project.

CTo identify new capabilities required to realize the target business model.

DTo define a taxonomy of services needed to support the change

Answer : C

According to the TOGAF standard, business models are used to understand and describe the business itself, including its organization, its objectives, and how it operates. This understanding is crucial when defining an enterprise architecture as it provides a frame of reference. Business models help in identifying new capabilities that the business must develop to achieve its future state as outlined in the target business model. These capabilities may be processes, information, or technologies that the business must adopt or adapt to fulfill the strategic objectives and deliver value. TOGAF emphasizes the alignment of IT with business strategy, and the business model serves as a key link in ensuring that the capabilities delivered by the enterprise architecture will enable the desired business outcomes.

Question 6

Consider the following example value stream:

Which of the following statements is most correct?

AThe value stream is decomposed into five value stream stages

BThe value stream consists of five sequential subprocesses.

CThe value stream is decomposed into five sequential events.

DThe value stream is mapped to five subsidiary value streams.

Answer : A

According to the TOGAF Series Guide to Value Streams (Version 1), a value stream stage is defined as ''a distinct part of a value stream that represents a group of activities contributing to an overall result''5.A value stream stage can be expressed as a noun phrase that indicates what outcome or state is achieved by completing the stage5. For example, some possible value stream stages are ''Product Ordered'', ''Payment Processed'', or ''Customer Satisfied''.The example value stream shows how an online retailer creates and delivers value for its customers by performing five value stream stages: ''Acquire Retail Product'', ''Advertise Channels'', ''Display Products'', ''Enable Selection'', ''Process Payment'', and ''Deliver Product(s)''5. Therefore, the value stream is decomposed into five value stream stages.

Question 7

Which ADM Phases match the following purpose descriptions?

A1 Phase D - 2 Phase B - 3 Phase G - 4 Phase A

B1 Phase C - 2 Phase E - 1 Phase H - 4 Phase C

C1 Phase C - 2 Phase F - 3 Phase H - 4 Phase B

D1 Phase C - 2 Phase F - 3 Phase G- 4 Phase D

Answer : D

The ADM Phases that match the purpose descriptions provided are: Phase C for the development of Information Systems Architectures to support the agreed Architecture Vision, Phase F for addressing the move from the Baseline to the Target Architectures by finalizing a detailed Implementation and Migration Plan, Phase G for providing architectural oversight of the implementation, and Phase D for describing the development of the Technology Architecture to support the agreed Architecture Vision.
