Product Life Cycle

The product life cycle is a central concept in business administration. It serves as an important analysis and planning tool that enables companies to predict and strategically manage the sales and profit development of their products in different phases. Therefore, the product life cycle plays a key role in many business models and decisions. [1]

Product Life Cycle Definition

The product life cycle is a view of the behavior of products as they change throughout their life cycle. It describes the change in the different phases of product development, market entry and leaving the market. This approach is an important part of business management and enables companies to optimize their decisions in terms of costs, sales and profits.

The product life cycle has four phases: Development, Introduction or Growth, Maturity or Saturation, and finally Decline. In each phase, the product has a different behavior - both in terms of sales and costs. The development phase is the most expensive and cumbersome phase, while the introduction phase is a phase of growth and the maturity phase is a period of lower costs and stable sales. In the last phase, the product can either decrease or disappear, depending on how it is received by the market.

A basic understanding of the product lifecycle is crucial for companies to make informed decisions regarding their product range. It also enables companies to understand when they should introduce new products to the market and which resources need to be invested in which product at which stage. This allows companies to manage their portfolio more efficiently and ensure that their business success is not impacted by unnecessary investments. [2]

Product Life Cycle Phases

The product life cycle, also known as the product lifespan, is a concept from business administration that deals with the phases of the life of a product or service. It is often used as a graphical representation to highlight the different phases: Introduction, Growth, Maturity and Decline. Each phase brings its own specific challenges and opportunities.

  • In the introduction phase, the company prepares the product's market entry. Since there is initially little market support, high investments in marketing and sales are necessary to gain awareness and acceptance. A pricing strategy is determined, and advertising campaigns are launched to stimulate demand. (Major product innovations are usually completed at this stage; improvements are made continuously as needed based on customer feedback.)
  • In the growth phase, demand rises rapidly and approaches its peak towards the end of this phase. The company should monitor and optimize its marketing strategies to remain effective, as more competitors may now emerge. Pricing also remains crucial to profitably expand market share.
  • In the maturity phase, the market is almost saturated: the product has reached the majority of potential customers, and it becomes increasingly difficult to attract new buyers. Sales and profits often stagnate. The company must review its business model and cost structure and make adjustments if necessary to remain competitive. This can include efficiency improvements or product policy measures (e.g., variants, service offerings) to create new buying incentives.
  • In the decline phase, demand continuously decreases until the product eventually disappears from the market. The company faces the decision to phase out the product or handle remaining demand through discounts and other clearance strategies. If appropriate, niche markets or alternative sales channels can be used to reach remaining customer segments. At the same time, resources should be redirected to new products to secure future revenues.

The product life cycle usually spans multiple cycles and can be used as a tool to predict the success of business projects. The product life cycle is a very useful concept for companies of all sizes, as it can help them identify opportunities and be prepared for challenges. Through proper analysis of the life cycle of a given product, companies can identify which phase elements are the most promising and what measures need to be taken to achieve the maximum possible success.

Distinction from the Innovation Cycle

For a successful and sustainable corporate strategy, it is essential to understand the product life cycle. It describes the development of ideas into new products and services, their promotion, distribution and replacement by new technologies or new competitors.

The term "product life cycle" is often confused with the innovation cycle, although it is different from it. The innovation cycle describes the development of a product or service from the idea to the market launch. In contrast, the product life cycle refers to the entire life of the product or service, beginning at development and ending after the product exits the market.

Comparing innovation and product lifecycles makes it clear that the latter focuses more on process, while the former focuses more on innovation - whether technological or strategic - to create new opportunities to generate revenue. [4]

Product Lifecycle Measures for Marketing and Sales

  • The launch phase is usually the most costly phase for companies. During this time, companies have to invest a lot of money in research and development to develop and test their new product. They also have to finance advertising campaigns to introduce the new product and introduce it to the market. Other costs associated with the launch phase are distribution costs and fees for registering the product with the government.
  • In the growth phase, the sales figures for the product increase. The costs for research and development gradually decrease, as the product has already been developed; instead, more resources are used for sales in order to reach more customers. In addition, this phase requires intensive marketing activities to increase the company's reputation as a brand on the market.
  • In the maturity phase, the growth of the product gradually slows down. The cost savings will be greater than in the growth cycle, and there is more scope for price discounts or other forms of customer experience. Therefore, the company needs to innovate marketing efforts to maintain or increase sales.
  • Eventually, every product reaches the decline stage of its life cycle. At this stage, the market has become saturated and consumers have developed a strong preference for other brands or newer versions. To continue to generate sales, the company must develop sales strategies that offer consumers something new - whether it's discounts or technological improvement - as well as use alternative distribution channels to market its products to end consumers.
