OGA-031 Sample Questions & Answers

The Serving relationship is used to model that an element provides its functionality to another element. In this case, the 'Create Customer Record' Application Service provides functionality that is used by the 'Process Customer Order' Business Process. The direction is from the service to the process.

The Migration Viewpoint is designed to show the transition from an existing architecture to a target architecture. It primarily uses elements from the Implementation & Migration Layer, such as Plateaus (to represent the intermediate states) and Work Packages (to represent the projects), making it the ideal choice for the project manager's request.

Equipment represents one or more physical machines, tools, or instruments that can create, store, manipulate, or transport materials. A 'CNC Milling Machine' perfectly fits this definition.

A Facility represents a physical structure or environment, such as a building or a room. The 'Main Production Hall' is a physical environment that houses the equipment, making 'Facility' the correct element.

This is the correct derivation path. An Application Interface exposes an Application Component, which realizes an Application Service. This service is used by (serves) a Business Process (or function), which is in turn performed by (assigned to) a Business Role. The transitive relationship from the start to the end of this chain is a Serving relationship.

A Product is an aggregation of services (and potentially other products) that are offered to customers. The Aggregation relationship correctly represents that the 'Mobile Banking' product is a bundle of services. Composition is too strong, as the services can exist independently of this specific product offering.

The Assignment relationship is used to link active structure elements to the behavior they perform. For example, a Business Role is assigned to a Business Process, or an Application Component is assigned to an Application Function.

This statement is false. A Gap indicates a difference between two Plateaus (e.g., a 'baseline' and a 'target' architecture). While it is commonly associated with two Plateaus, the ArchiMate specification allows for more complex scenarios. For example, a gap might represent a missing capability needed to bridge from one state to the next without being explicitly tied to both.

The Access relationship models the access of a behavior or active structure element to a passive structure element (e.g., a data object). It can represent reading, writing, or modifying data. Therefore, it is the correct relationship to show that the Application Component writes to the Data Object.

This is the most precise and complete way to model the requirement. A 'Constraint' element from the Motivation layer correctly represents the non-functional requirement. This constraint is met (realized) by an 'Encryption' Application Service, which represents the security functionality. Finally, this service must be implemented by a concrete part of the application, so the 'Third-Party Integration Service' Application Component realizes the 'Encryption' Application Service. This creates a clear traceability from requirement to implementation.

This is the core distinction. A Business Function is a grouping of behavior based on a chosen set of criteria (e.g., skills, knowledge), representing a capability of the business (what it does), such as 'Marketing' or 'Finance'. A Business Process represents a sequence of behaviors that achieves a specific result (how it does it), such as 'Onboard New Customer'.
