The Open Group OGEA-103 Exam With Confidence Using Practice Dumps

EA applies architecture principles and practices to analyze, design, plan, and implement enterprise analysis that supports digital transformation, IT growth, and the modernization of IT2. EA also helps organizations improve the efficiency, timeliness, and reliability of business information, as well as the alignment, agility, and adaptability of the architecture to the changing needs and requirements3. Therefore, the best summary of the purpose of EA is to guide effective change.

The scenario clearly states that:

Theoverall objective is known,

BUT the EA team is expected todefine the scope, shared vision, and requirements,

The company uses aniterative approach,

The CEO wantsrepurpose and reuse rather than replace,

This is amajor strategic shift(new markets, new products, new crop mix).

According to the TOGAF standard, whenthe problem must be understood, andscope, vision, and requirements are not yet defined, the correct starting point isPhase A: Architecture Vision, using aniteration cycle.

This is also consistent with the “baseline-first” approach recommended in the TOGAF Series Guides for situations where:

the business direction is known but high-level,

detailed impacts must be discovered,

and the organization wants to reuse existing capabilities rather than replace them.

OptionBis the only answer that:

Begins byunderstanding the problem,

Definesthe structure of the change,

Usesiteration cyclesstarting with abaseline-first approach,

Leads intotransition planning,

Supports clarification of theshared visionandrequirements,

Fits the CIO’s instruction to “define the scope, shared vision, and requirements.”

This matches exactly what TOGAF prescribes in early-cycleArchitecture Vision and initial iterations.

Based on the web search results, architecture partitioning is a technique that divides the Enterprise Architecture into smaller and manageable segments or groups, based on various classification criteria, such as subject matter, time, maturity, volatility, etc.12 Architecture partitioning is used to simplify the development and management of the Enterprise Architecture, by reducing complexity, improving governance, enhancing reusability, and increasing alignment and agility12. Therefore, the statement that partitions are used to simplify the management of the Enterprise Architecture is correct.

The other statements are incorrect because:

•Partitions are not equivalent to architecture levels. Architecture levels are different layers of abstraction that describe the Enterprise Architecture from different perspectives, such as strategic, segment, and capability3. Partitions are subsets of architectures that are defined within or across the levels, based on specific criteria1.

•Partitions do not necessarily reflect the organization’s structure. The organization’s structure is one possible criterion for partitioning the architecture, but it is not the only one. Other criteria, such as business function, product, service, geography, etc., can also be used to partition the architecture12.

•Partitions are not defined and assigned to agile Enterprise Architecture teams. Agile Enterprise Architecture is an approach that applies agile principles and practices to the architecture work, such as iterative development, frequent feedback, adaptive planning, and continuous delivery4. Partitions are not a specific feature of agile Enterprise Architecture, but a general technique that can be applied to any architecture method or framework, including TOGAF12.
