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.
