Which of the following is a major weakness of the product life cycle theory?

The assertion that many innovations come from outside the USA is indeed a major weakness of the product life cycle theory because this theory primarily originated from observations of market behavior in developed countries, particularly the United States. Consequently, its framework inherently reflects a Western-centric view, overlooking the significant contributions and innovations emerging from global markets.

As the marketplace has evolved, particularly with globalization, innovations do not occur in isolation within a single country; they can emerge and be launched in various countries simultaneously. By focusing primarily on the U.S. perspective, the theory fails to account for the dynamic and diverse nature of global innovation. This oversight can lead to an incomplete understanding of how products are developed and marketed in today's interconnected world, ultimately limiting its applicability in a global business context.
