Consider the diagram:(A diagram showingX, Y, and Zconnected toFinancial Processingusing black diamonds.

Comprehensive and Detailed In-Depth Explanation:

Theblack diamond notationinArchiMaterepresents aComposition relationship, which is used to indicatewhole-part relationshipsbetween elements.

Financial Processingis thewhole(parent element).

X, Y, and Zaresub-functions, meaning they arepart ofFinancial Processing.

Compositionisa strong relationship, meaning thesub-functions (X, Y, and Z) do not exist independently outside Financial Processing.

Analysis of Answer Choices:

✅A. The financial processing function is composed of three sub-functions X, Y, and Z.→✅Correct Answer

Composition relationshipsin ArchiMate indicate that one element ispart of anotherin a strict, whole-part hierarchy.

ArchiMate 3.2 Specification, Section 6.4.2, definesComposition as a structural relationship where the child elements belong strictly to the parent.

SinceFinancial Processing contains X, Y, and Z as integral sub-functions, this is the correct choice.

✅B. The financial processing function aggregates the three sub-functions X, Y, and Z.→❌Incorrect

Aggregationis aweakerrelationship in ArchiMate compared toComposition.

In Aggregation,the sub-functions can exist independently, whereas in Composition, theycannot.

ArchiMate 3.2 Specification, Section 6.4.1, states thatAggregation does not enforce a strict whole-part relationshiplike Composition does.

✅C. The financial processing function is influenced by the three sub-functions X, Y, and Z.→❌Incorrect

Influence relationshipsin ArchiMatedo not represent whole-part structures.

Influence is amotivation relationship, meaning it represents animpact or effect, not astructural dependency.

✅D. The financial processing function is assigned the three sub-functions X, Y, and Z.→❌Incorrect

Assignment relationshipsare used to indicate thata behavior element (e.g., function, process) is performed by an active structure element (e.g., role, actor, component).

This diagramdoes not depict an assignment relationship; instead, itshows a structural composition.

Final Answer:✅A. The financial processing function is composed of three sub-functions X, Y, and Z.
