Decline Model

The Decline Model describes how a product, technology, or industry gradually loses relevance and sales over time. Initially, it grows quickly during its introduction and growth phases, but as newer alternatives emerge, demand decreases. This pattern shows a steady reduction in market interest and profitability until the product eventually becomes obsolete or is phased out. Understanding this model helps businesses manage product lifecycles, plan for innovation, and avoid losses by timing updates or discontinuations appropriately.
