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.

The techniques best suited to illustrate the interaction of runtime building blocks are:A. Activity diagrams - Useful for showing the flow of control among various activities and decisions in the system.B. Sequence diagrams - Ideal for depicting the order of messages exchanged between components or objects in a specific scenario.C. State diagram - Shows how a component or an object changes its state in response to events, highlighting dynamic behavior.G. Depiction of screen flows (sequence of user interactions) - Useful for visualizing the sequence of user interactions with the system, which is critical for user-centric design and runtime behavior analysis.

Iterative and incremental design methods are fundamental in software development, allowing for flexibility, better risk management, and focused delivery of functional components.

• A: Iterations involve repeated cycles of design, development, and testing, which help manage and resolve uncertainties as more knowledge is gained throughout the project lifecycle.
• B: The iterative process facilitates early detection of design and integration issues, as feedback can be incorporated promptly to refine the system progressively.
• F: Incremental design focuses on delivering functional increments of the product, ensuring that key functionalities are developed and delivered in priority order, allowing for early testing and refinement.
