The product life cycle refers to the entire journey of a product or service, from its development and launch to its eventual decline and withdrawal from the market. This process is generally divided into five stages: development, introduction, growth, maturity and decline.
Long used in marketing, the product life cycle provides a form of biography for a product by showing how it evolves over time. Also known as the product life cycle curve, the concept covers every stage from the initial creation of the product idea to its removal from the market.
Businesses frequently use the product life cycle to evaluate a product’s current position and determine the most appropriate next steps. Since marketing is a highly dynamic field, decisions relating to pricing, promotion, positioning and investment may need to be reviewed at every stage of the cycle.
The product life cycle should not be confused with Product Lifecycle Management, or PLM. The product life cycle describes the stages a product passes through in the market, while PLM refers to the systems and processes used to manage a product throughout its entire lifecycle.
The five stages of the product life cycle can be summarised as follows:
Development: This stage takes place before the product enters the market. The concept is defined, researched, designed and tested. Concept testing may also be conducted with members of the intended target audience.
Introduction: The product is launched and introduced to the market. At this stage, marketing investment is generally high, while sales and customer awareness are still developing.
Growth: Demand, sales and profitability begin to increase. The product gains wider recognition, and the business may expand its distribution and marketing activities.
Maturity: Sales reach a more stable level after a period of rapid growth. Competition is usually stronger at this stage, and businesses focus on maintaining market share and customer loyalty.
Decline: Demand and sales begin to decrease as customer preferences change, new alternatives enter the market or the product loses relevance. At this point, the business may reposition, update or gradually withdraw the product.
The main advantages of understanding and managing the product life cycle include:
- Making more informed and rational decisions based on the product’s current stage.
- Increasing the potential return on investment following product launch.
- Supporting profitability and encouraging demand growth.
- Updating marketing strategies to remain connected with the target audience.
- Protecting and strengthening customer loyalty and product appeal.
If the product life cycle is not managed effectively, the product may fail to reach its full commercial potential. It may also experience a shorter market life, declining profitability and a weaker competitive position.
For this reason, businesses should understand the stages of the product life cycle and manage each stage with appropriate product, pricing, distribution and marketing strategies.
