- Introduction – This is the first stage of the product life cycle. Once a product is developed, the first step is its introduction into the market. During this stage, the product is released into the market for the very first time. This product development life cycle stage is at high stake but does not decide whether the product will be successful or not. Additionally, a lot of marketing and promotional activities are undertaken, and capital is pooled so that the product reaches the consumers. At this stage of product life cycle management, companies are able to understand how users will respond to the product. Precisely, the idea is to create a huge demand

- Growth – In the growth stage, consumers start to take action. They buy the product; the product becomes popular and results in increased sales. There are other companies also that notice the product as it starts getting more attention and revenue. When the competition is heavy, a higher amount of money may be pooled into the market. The market for the product expands and it may also be tweaked at this stage to ensure some features, etc., are improved. Competition may also force you to cut down the prices. Nonetheless, sales increase and therefore the product and market growth.

- Maturity – In the maturity stage, sales slow down, indicating that the market has begun to reach saturation. This is also one of the stages of the product life cycle when pricing becomes competitive. This makes the profit margins thinner. In this stage, the purpose of marketing is to fend off competition and sometimes, altered products are introduced

- Decline – While companies make all efforts throughout the different stages of the product life cycle to ensure that it stays alive in the market, an eventual decline cannot be ruled out. This is why it becomes important to know what product life cycle is at first. When a product is in the decline stage, the sales drop due to a change in consumer behaviour and demand. The product loses its market share and competition also deteriorates. Eventually, the product retires from the market.
