Exam OGA-031 Topic 1 Question 59 Discussion

Comprehensive and Detailed In-Depth Explanation:
This diagram represents agoal decomposition modelinArchiMate, specifically illustratinghow multiple lower-level goals contribute to a higher-level goal.
* The top three goals ("Increase Premium," "Reduce Consultant Usage," and "Increase Internal Labor Expense") are connected to "Reduce Expense Ratio" using an aggregation relationship.
* Aggregation in ArchiMate indicates that multiple elements together contribute to forming a larger whole.
* This means"Reduce Expense Ratio from 15% to 10%" is composed of these three contributing goals.
Analysis of Answer Choices:
#A. The goal "Reduce Expense Ratio from 15% to 10%" combines three other goals.##Correct Answer
* The aggregation relationship used in the diagram indicates that the three top-level goals together support or combine to form the "Reduce Expense Ratio" goal.
* ArchiMate 3.2 Specification, Section 6.4.1, states thatAggregation represents a "whole-part" relationship, meaning the main goal (Reduce Expense Ratio) is achieved by achieving the contributing goals.
#B. The goal "Reduce Expense Ratio from 15% to 10%" will be achieved if at least one of the other three goals is achieved.##Incorrect
* This would require an Influence or Contribution relationshiprather than Aggregation.
* Aggregation meansall three goals contribute to the overall goal, not just one of them.
#C. The goal "Reduce Expense Ratio from 15% to 10%" must be achieved before any of the other three goals is achieved.##Incorrect
* This would imply a triggering or dependency relationship, which is not present in the diagram.
* The diagram does not indicate a sequence of achievements.
#D. The goal "Reduce Expense Ratio from 15% to 10%" is similar to the three other goals.##Incorrect
* Therelationship shown is not equivalence or similarity, butaggregation, meaning the three smaller goals form part of the main goal.
#A. The goal "Reduce Expense Ratio from 15% to 10%" combines three other goals.
