Question
What two strategies let one product suit a range of percentiles?
Answer
Designing the product to be adjustable, and producing it in a range of fixed sizes. Many products use both.
Question
Adjustability — one advantage and one disadvantage.
Answer
Advantage: one product covers the whole 5th–95th range with one set of tooling. Disadvantage: the mechanism adds cost and weight, can fail, and only helps if the user actually adjusts it.
Question
A range of sizes — one advantage and one disadvantage.
Answer
Advantage: each item is simpler, lighter and cheaper, with nothing to break. Disadvantage: several sets of tooling and stock, and the user must pick the right size.
Question
Give a product that uses BOTH strategies and say why.
Answer
A cycle helmet: two or three shell sizes keep each one light, and an adjustable cradle closes the remaining gap — a loose helmet does not protect in a crash.
