These stages include:

1. Introduction - is characterized by a low growth rate of sales as the product is newly launched. Demand is very low and consumers may not know much about the product.

2. Growth - the public becomes increasingly aware of the product; demand, sales and revenues begin to increase.

3. Maturity - sales gets to its peak. This is because the product reaches market saturation, and competition with other similar products grows increasingly fierce.

4. Decline - sales, growth, begins to shrivel up, profits decline, competition still remains high, and the product ultimately reaches its ‘death' and is recalled from the market or production stopped entirely.
