Briefly define the fundamental concepts of strategy and competitive advantage and explain the crucial difference between operational effectiveness and strategic positioning.

Given the dynamic nature of the business environment and the possibility of core rigidities, discuss the critical need for a strategy to be dynamic and adaptive. Using the company you chose in part (2), hypothesize a future external change (e.g., a technological breakthrough, a major regulatory shift, or the entry of a disruptive substitute) that could threaten its current advantage, and propose a specific strategic action the company should take to adapt and maintain its superior performance.
