Engineering Design Process and Systems Thinking
From needs to specifications
Problem framing
Good engineering begins with a clear problem statement. Engineers translate a broad need into measurable requirements, such as load capacity, temperature range, speed, efficiency, lifetime, or allowable error.
Common requirement types
Systems thinking
A system is a set of interacting parts that produce an overall behavior. Systems thinking helps engineers see inputs, outputs, feedback loops, and unintended consequences.
Ask better questions
Instead of asking only 'How do we build it?', also ask 'Who uses it?', 'What can fail?', 'How will it be maintained?', and 'What happens when conditions change?'

Which is the best example of a measurable engineering requirement?
Measurable requirements can be tested quantitatively.
Correct answer: The system must support a N load with a safety factor of
What is one benefit of systems thinking?
Other acceptable answers include spotting feedback loops, hidden failures, or unintended consequences.
Correct answer: it helps identify interactions
Why are constraints important in design?
Constraints shape what solutions are feasible and acceptable.
Correct answer: They define the practical limits of possible solutions
