1.3.1.3e - Product differentiation

Explain the purpose of product differentiation.

Use e - product differentiation to connect the rule to the data and decision in the question.

This matters because e - product differentiation determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply e - product differentiation to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: e - Product differentiation is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
