Designing effective interfaces is critical in software architecture, ensuring that they are both usable and robust. The characteristics that generally make interfaces more desirable include:

• A: Easy to extend - An interface should be designed such that it can be extended without breaking existing implementations. This characteristic is important for maintaining backward compatibility while allowing for future growth and changes in requirements.
• C: Clear descriptions of assertions and prerequisites - Interfaces should clearly specify what is required of the caller (prerequisites) and what the interface guarantees in return (assertions). This clarity is vital for ensuring that the interface is used correctly.
• G: Hard to misuse - An interface should be designed in such a way that there is little room for incorrect usage by the client. This involves making the interface intuitive and minimizing the potential for errors, which improves the robustness and reliability of the software system.

These characteristics help in creating interfaces that are not only functional but also robust, maintainable, and adaptable to future needs, aligning with best practices in software architecture.

In the context of software architecture, the common definitions often focus on the structural aspects of system design. Here’s how the chosen answers align with the iSAQB® guidelines on software architecture:

• Building Blocks (B): A fundamental concept in software architecture, building blocks refer to the modular units from which the system is constructed. These can include modules, classes, or components, all of which are vital for defining the structure and behavior of the system.
• Relationships (D): Relationships in software architecture define how different components or building blocks interact with each other. These interactions are essential for understanding data flow, dependencies, and communication patterns within the system.
• Components (E): Components are larger than building blocks and encompass them, representing significant units of functionality within the system. Each component usually encapsulates a portion of the system's overall functionality and interacts with other components via interfaces.
• Interfaces (G): Interfaces define the points of interaction between components or building blocks. They are critical for ensuring that components can function independently yet interact seamlessly when required.

Documenting the right views in software architecture is crucial for addressing different stakeholder concerns and ensuring the architecture is comprehensible and manageable.

• A: Deployment view illustrates the physical deployment of software on hardware and is essential for understanding how different parts of the system are distributed across platforms and environments.
• C: Runtime view shows how various components of the system interact at runtime, which is vital for understanding system behavior and performance under different operational conditions.
• H: Building-block view (also known as the module view) describes the static organization of the software in modules or components, including their responsibilities and relationships. This view is foundational for developers and maintainers.
