質問 1：
How does management and architects work together? Decide which statements are true and which are false.
(Assign all answers.)

正解：

Explanation:
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.

質問 2：
Conway's law sometimes is referred to as "If you have four teams working on the compiler, you'll get a 4-pass compiler." Which interpretations of this law are true, which are false? (Assign all answers.)

正解：

Explanation:
The interpretations of Conway's law that are true and false are as follows:
* True:
* Structures of software architecture and associated organization are congruent (B).
* Software architecture is particularly important when creating compilers .
* False:
* You need four teams to build a compiler (A).
* Certain types of software are not suitable for the use of software architecture (D).
Conway's law suggests that the structure of systems designed by an organization will mimic the communication structures of that organization1. This means that the way teams are organized and communicate will influence the design of the software they are developing. Here's an explanation of each interpretation:
* True Statements:
* (B): The law implies that the technical structure of a system will reflect the social boundaries of the organization that produced it, which means the architecture of the software and the
* organization will be congruent1.
* : When creating complex systems like compilers, the architecture is influenced by organizational structures, making it crucial to consider how teams are organized and how they communicate1.
* False Statements:
* (A): The number of teams does not dictate the necessity of a multi-pass compiler; it's a metaphorical example to illustrate that organizational structure can influence technical design1.
* (D): All types of software can benefit from thoughtful software architecture; the statement is a misinterpretation of Conway's law, which does not deem any software unsuitable for architectural practices1.
Conway's law is a valuable consideration in software engineering, reminding us that organizational decisions can have a significant impact on the design and functionality of the software.

質問 3：
You are responsible for the documentation of the software architecture of a large development project. The project consists of three teams, each with its own architect, but with you as the person having overall responsibility of the entire project's software architecture.
Which of the following measures are beneficial? (Assign all answers.)

正解：

Explanation:
A) BeneficialB) BeneficialC) Not BeneficialD) Not BeneficialE) Beneficial In the context of documenting the software architecture for a large development project with multiple teams, the following measures can be considered beneficial:
A) Dividing the whole architecture documentation into sub-documents for each of the three sub-projects can be beneficial as it allows each team to focus on their specific area while maintaining a modular approach to documentation1.
B) Predefining the structure of the entire architecture documentation ensures consistency and coherence across all sub-projects. It helps in maintaining a uniform standard and facilitates easier integration of the sub-documents into the overall project documentation1.
C) Leaving the decision regarding the documentation structure to the team that first begins the documentation of its sub-project is not beneficial. This approach can lead to inconsistencies and may result in a lack of uniformity across the project's documentation1.
D) Rejecting word processing for the documentation because it is not connected with the source code is not beneficial. While it is important to link documentation with the source code, word processing tools can still be used effectively for creating comprehensive documentation. Tools like version control can be used to maintain a connection between the documentation and the source code1.
E) Having developers document their parts of the architecture documentation using source code can be beneficial. This approach ensures that the documentation is close to the implementation and can be more easily kept up-to-date1.
These measures align with the best practices for software architecture documentation as per the iSAQB SOFTWARE ARCHITECTURE - FOUNDATION LEVEL documents, which emphasize the importance of clear, consistent, and coherent documentation in software architecture1.
