Comprehensive and Detailed In-Depth Explanation:
Theblack diamond notationinArchiMaterepresents aComposition relationship, which is used to indicate whole-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.
#A. The financial processing function is composed of three sub-functions X, Y, and Z.
