Question

We begin by clarifying the question and listing the options to ensure we assess each statement accurately.
Option a: The design class diagram is developed during Design phase. This aligns with typical software engineering practice, where the design class diagram is produced during the design phase to model how the system will be structured, including classes, their attributes, methods, and relationships. This statement is generally considered true.
Option b: The design class diagram is an important tool to show the users how the system will actually work to meet their needs. This is misleading because a design class diagram is primarily a technical artifact used by developers to implement the system; it is not typically presented to users as a depiction of how the system will work for users. This statement is not true, as it overstates the audience and purpose of the DCD.
Option c: The design class diagram contains operations as well as the attributes required by the system. Indeed, a design class diagram details the methods (operations) that classes provide, along with their attributes, to specify behavior and data. This statement is true.
Option d: The design class diagram defines software building blocks. In essence, it identifies key classes and their relationships, which constitute the building blocks of the software architecture, so this statement is true.
Summarizing the evaluations, option b is the incorrect claim, because it mischaracterizes the role and audience of the design class diagram by asserting it is primarily a user-facing depiction of system operation. The other statements accurately describe aspects of the DCD: its placement in the Design phase, inclusion of attributes and operations, and representation of core building blocks.
