In Brooks' "No Silver Bullet," the concept of "invisibility" is highlighted as a fundamental aspect of modern software systems. What is a consequence of this invisibility, and which of the following examples best illustrates this issue?

refers to the process of designing and testing a product incrementally (little by little) until it is fully complete, ensuring minimal errors.

Which one of the following requirements-analysis techniques is Netflix known for using the most to inform their software development?

What is functional decomposition?

Decomposing a task, function, module, or system into smaller sub-tasks, sub-functions, or sub-modules
