1.3.1.3d - Competitive advantage

Explain competitive advantage for a product or service.

Use d - competitive advantage to connect the rule to the data and decision in the question.

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

Example: apply d - competitive advantage to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: d - Competitive advantage is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
