The interpretations of Conway’s law that are true and false are as follows:

• True:
• False:

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:
• False Statements:

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.

When designing external interfaces, several considerations must be taken into account:A. Volatility of neighbouring systems - Changes in neighboring systems can affect the stability and compatibility of interfaces, requiring interfaces to be adaptable to changes.C. Protocols enforced by neighbouring systems - It's crucial to align with the protocols used by neighboring systems to ensure seamless communication and interoperability.D. Expected amount of parallel calls - This affects the scalability and performance requirements of the interface, as it must be designed to handle the expected load efficiently.

The layered architectural pattern, also known as n-tier architecture, is a common framework in software development that organizes a system into distinct layers with specific roles and responsibilities. The primary advantage of this pattern is its Separation of Concerns (SoC), which means each layer is independent and can be understood without the others2. This separation enhances flexibility because changes in one layer can be made with minimal impact on others, allowing for easier maintenance and scalability12.

While creating high-performance systems (B) and being able to use application servers © are also considerations in system architecture, they are not the main benefits attributed to the layered pattern. The layered architecture is more about managing complexity and promoting modularity rather than directly enhancing performance or dictating the use of specific technologies like application servers34.

The software architect is typically responsible for the following quality characteristics:A. The performance of the software - Ensuring that the software meets performance criteria and behaves efficiently under specified conditions is a primary responsibility of the software architect.C. The suitability of the software design for its purpose - Architects must ensure that the design effectively meets the intended functions and requirements, addressing the suitability of the software for its purpose.

These answers are derived from established software architecture practices and principles, focusing on the roles and responsibilities of software architects in ensuring quality and effective documentation.
