Product Life Cycle (PLC): The life expectancy of a product is thought to be finite; the product life cycle diagram is used to describe the change in sales during various stages of the product life. The first stage is Introduction where the product is launched into the market and the sales will most likely start low. The second stage is Growth this means the product is becoming successful and sales will start to grow rapidly as it becomes established. Moreover, the third stage is Maturity; this occurs when the product is at its peak and has displaced the previous market leader for example replacement of CD’s with MP3. The final stage is Decline this is when the product sales begin to fall, this is usually due to lack of successful innovation or creation of new varieties to keep consumer interest or expand the target market.
