This document discusses strategies for large corporations to respond to challenges from maverick competitors. It outlines lessons from past instances of underdog brands temporarily capturing market share. The key lessons are: do not ignore small threats as they can grow rapidly; competitors may build emotional connections and polarize customer segments; gather intelligence on competitors' strategies, weaknesses, and leadership; understand the market terrain; and design dynamic plans that can change based on the situation. The document uses Patanjali's rise in India as an example, advising that established brands should not have been complacent and should have prepared better strategies to respond to Baba Ramdev's systematic approach.
