質問 3：
Decide if the following statements are true or false. The performance of a system (response time or throughput) often competes with its... (Assign all answers.)

正解：

Explanation:
The performance of a system often competes with its:
* Flexibility (A) - True1
* Memory usage (B) - True1
* On-time completion of the project C - False
* Adaptability (D) - True1
* Usability (E) - True1
* Security (F) - True1
* Testability (G) - True
In system design, performance trade-offs are a critical consideration. Here's an explanation of how each listed aspect competes with system performance:
* Flexibility (A): Systems designed for high performance may be less flexible because they are optimized for specific tasks or conditions1.
* Memory Usage (B): High-performance systems may require more memory to store data and instructions for rapid access, which can be at odds with limited memory resources1.
* On-time Completion of the Project : While performance considerations can impact project timelines, they do not inherently compete with the on-time completion of a project.
* Adaptability (D): Systems that need to perform well under varying conditions may sacrifice adaptability, as they are tightly coupled with their performance optimizations1.
* Usability (E): Sometimes, the pursuit of performance can lead to complex user interfaces or workflows, affecting usability negatively1.
* Security (F): Security measures can introduce additional processing and checks, potentially slowing down system performance1.
* Testability (G): High-performance systems may be harder to test due to their complexity and the need for specialized testing environments or tools1.
These trade-offs highlight the importance of balancing different system attributes to meet the overall goals and constraints of a project.

質問 4：
Which statements with regard to project objectives and architectural objectives are true and which are false?
(Assign all answers.)

正解：

Explanation:
A) FalseB) TrueC) TrueD) False
A) Architectural objectives and project objectives need to be identical.
* This is false. Architectural objectives are concerned with the technical goals and quality attributes of the system, while project objectives are broader and include timelines, budgets, and overall project deliverables12.
B) Most of the time, architectural objectives are of a more long-term nature than project objectives.
* This is true. Architectural objectives often focus on the sustainability and maintainability of the system, which are long-term considerations, whereas project objectives may be more immediate and focused on the project's completion12.
C) Architectural objectives and project objectives need to be negotiated between the concerned parties.
* True. Both sets of objectives should align with the stakeholders' needs and the project's overall goals, and thus require negotiation to ensure that all parties' interests are addressed3.
D) Architectural objectives are a subset of project objectives.
* This is false. Architectural objectives are not necessarily a subset but are related and should support the project objectives. They deal specifically with the architecture of the system, which is one aspect of the project
