Summary
Teaches students that a clearly defined problem statement is the most critical step in engineering — a vague problem leads to vague solutions. Uses real examples to show how engineers scope and frame challenges.

Discussion questions
Discussion
- What is the difference between a vague problem and a well-defined problem?
- What is a criterion for success? Give an example.
- What is a constraint? Why can't engineers just ignore constraints?
- Can the same problem have multiple good definitions? What changes?
Quick work-a-long
Vocabulary: problem statement, criterion, constraint, need, scope, define.
Try it: Write two problem statements for the same challenge (e.g., 'students get wet walking from the bus'): one vague and one specific with criteria and constraints. Compare with a partner — which one gives the engineer more to work with?
