As an architect, you can specify the following characteristics of a black-box building block:

• Compliance with functional requirements (A)
• Compliance with non-functional requirements (B)
• Purpose and/or responsibility (D)
• Method signature of public interfaces (E)
• Data formats of public interfaces (F)

In software architecture, a black-box building block is a component whose internal structure is not exposed to or understood by other components. It is defined only by its provided functionality and the services it offers. Here’s a detailed explanation of each characteristic:

• Compliance with Functional Requirements (A): This refers to the ability of the building block to perform the functions it was designed to do, which are often captured in a functional specification document.
• Compliance with Non-functional Requirements (B): These are criteria that can be used to judge the operation of a system, rather than specific behaviors. This includes requirements related to scalability, performance, security, and reliability.
• Purpose and/or Responsibility (D): This defines the role the building block plays in the overall system architecture, including its responsibilities and the services it provides.
• Method Signature of Public Interfaces (E): The method signature defines the interface that other components can use to interact with the building block. It includes the method name, parameters, and return type.
• Data Formats of Public Interfaces (F): This specifies the format and structure of the data that is accepted or returned by the building block’s public interfaces.

These characteristics are essential for ensuring that the building block can be effectively integrated into a larger system and interact with other components as expected.

A) TrueB) FalseC) TrueD) True

A) The project plan from management is influenced by architectural decisions.

• True. Architectural decisions often have significant implications on the project plan, including timelines, resource allocation, and technical approaches1.

B) Cost estimates are primarily the responsibility of the architect.

• False. While architects may contribute to cost estimates, especially regarding design-related expenses, it is typically the management’s responsibility to oversee and finalize cost estimates for the entire project2.

C) Architects advise project management on the definition of work packages.

• True. Architects play a crucial role in defining work packages, particularly in ensuring that the technical aspects of the project are accurately captured and planned for1.

D) Management and architects cooperate on handling of technical risks.

• True. Both management and architects need to work closely to identify, assess, and manage technical risks throughout the project2.

Understandability in architecture documentation is crucial as it directly impacts the ease with which the architecture can be reviewed, maintained, and extended. Here’s why the chosen answers are relevant:

• It is an important quality characteristic (C): Understandability ensures that the architecture is accessible not only to the creators but also to other stakeholders like new team members, management, and maintenance personnel. This aids in the effective communication of the architecture’s intent, usage, and functionalities.
• It is a quality characteristic together with simplicity and brevity (E): Simplicity and brevity contribute to making complex systems easier to understand. Concise and straightforward documentation helps in quicker comprehension and reduces ambiguities.
• It is a quality characteristic together with scope and completeness (F): While it is important for the documentation to be comprehensive, it should also clearly define the scope of the system. This helps in setting the right expectations and ensures that the documentation covers all necessary aspects thoroughly, thus enhancing understandability.

• “Documenting Software Architectures: Views and Beyond” by Paul Clements et al. emphasizes the importance of these aspects in effective architecture documentation.
• ISO/IEC 42010 also highlights understandability as a fundamental quality characteristic of architectural descriptions.
