What are disadvantages of product life cycle?

The product life cycle (PLC) can oversimplify the complexities of real-world markets, leading to inaccurate predictions about a product's performance and lifespan. It may encourage businesses to focus too heavily on stages rather than on continuous innovation and customer needs. Additionally, the PLC model does not account for external factors like competitive dynamics or technological changes, which can significantly impact a product's trajectory. This can result in missed opportunities or misallocation of resources.
