Question
What does cost really mean in material selection?
Answer
Cost per part rather than per kilogram, including processing, waste and finishing — and over the whole product life, since a coating renewed twice is bought three times.
Question
What does availability really mean?
Answer
Available in the section and grade required, within the lead time, at a usable order quantity, and ideally from a second source so one supplier cannot stop production.
Question
Why is product life part of sustainability?
Answer
A product lasting fifteen years in a slightly worse material beats one lasting four in a better one, because the second is made and transported nearly four times over.
Question
How is a conflict between the three factors resolved?
Answer
Essentials first — cost never buys back a failed property. Then whole-life cost, then what is genuinely available. Finally, state the trade-off you accepted and why.
