Positioning
Al Ries, Jack Trout
The book that reframed marketing as a battle fought inside the customer's head, not in the product itself.
Own one word in the customer's mind.
Al Ries and Jack Trout argue that customers hold a mental ladder for every category, and a brand wins by claiming a clear, ownable rung. It teaches CMOs to compete on perception and focus, which is the foundation most modern positioning work still builds on.

Jenni Romaniuk, Byron Sharp, Professor of Marketing Science and Director of the Ehrenberg-Bass Institute Byron Sharp
What decades of marketing-science data say about how brands actually grow, which often contradicts the strategy deck.
Reach light buyers; build mental availability.

Made to stick
Chip Heath, Dan Heath
Why some ideas lodge in memory while better ones evaporate, and what makes the difference.
Concrete, unexpected ideas get remembered.
