Product Life Cycle (PLC) Stages

The Product Life Cycle (PLC) is based upon the biological life cycle. For example, a seed is planted (introduction); it begins to sprout (growth); it shoots out leaves and puts down roots as it becomes an adult (maturity); after a long period as an adult the plant begins to shrink and die out (decline).

Each product may have a different life cycle
PLC determines revenue earned
Contributes to strategic marketing planning
May help the firm to identify when a product needs support, redesign, reinvigorating, withdrawal, etc.
May help in new product development planning
May help in forecasting and managing cash flow
