As each step is taken for next desired outcome to be achieved and events are built on contextual level, your understandings of past do not have direct relation to what will be happening, which is also known as problem with inductive thinking.

The only function of feedback is to drive change toward a defined outcome. Therefore, only relevant feedback should be prioritized, requiring strategy. Since the goal is to change states, feedback is the only available source for moving forward without compromising constraints.

Not all feedback is useful in system interactions. Feedback is system-to-system communication that influences user perception of design. If unnecessary, it can add cognitive load, leading to negative results by hindering user flow rather than enhancing it.

Design, while having a view as being about function, has its own function as well. It serves product or service success which is about user's preferences and decision making. So over design, many products need investment in things their user's decisions are defined by.

The most fascinating aspect of problem-solving is that, up until the design phase, everything operates on a meta level, free from subjective evaluation and driven solely by natural principles. This makes it a far more accessible field for innovation and the creation of new ideas.

The point of pre-executive research/test processes is to mitigate potential risks from uncontrolled variables that could lead to bigger failures. Thus, success should be defined by a threshold where these risks are minimized within constraints, aligning with its root concept.
