What Is a Product Life Cycle?

Product Life Cycle

The product lifecycle is a model that describes the stages a product goes through from its development to its eventual decline. It is used by businesses to plan and manage the growth and decline of their products. 

Businesses and organizations can make informed decisions about their products when they have a better understanding of the product lifecycle. 

You can derive various benefits from deeply understanding the meaning and stages of the product lifecycle. Such as:

  • Accurately forecasting the market trends
  • Allocating resources more effectively, such as investing in product development during the introduction stage and reducing costs during the decline stage
  • Making informed decisions about their product portfolio, such as which products to continue developing and which to discontinue
  • Provides valuable insight into a company’s competitors and product offerings. 

The concept of the five stages of the product lifecycle is widely attributed to Harvard Business School professor Theodore Levitt. Levitt first introduced the concept in 1965 in his article “Exploit the Product Life Cycle.” 

The article provided a framework for understanding how a product progresses through its lifecycle and the challenges and opportunities that businesses face at each stage.

The five stages of the product life cycle are

  1. Development
  2. Introduction
  3. Growth
  4. Maturity
  5. and Decline

What Is a Product Life Cycle?

As the name indicates, the product life cycle is the lifespan of a product. It includes the time from product launch until its withdrawal from the market.

Consider the example of CD players. Their sales decreased significantly in the mid-2000s. Despite the discontinued CD players, you can still use them for another decade.

The point is that this serves as an excellent example of a product whose life cycle has reached its endpoint.

When you launch a product in the market, it is often not in the common knowledge of the customer.

Its life cycle begins from new and valuable to shifting towards regular updates. It finally retires from its market circulation at a certain point.

The product’s retirement depends on decreased sales, higher competition, lesser demand, and saturation.

The product life cycle is continuous. Companies usually rely on product life cycle analysis to understand market demands. They implement strategies to increase their product lifespan.

You can find many efficient product management tools in the market to make your work easier and more effective.

The Importance of Product Life Cycle

The product life cycle is helpful for managers, developers, and designers.

Identifying the life cycle stage the product is in offers enough insights. 

The insights include increasing that stage’s longevity and implementing strategies that can keep the product from declining. 

The following are the key advantages of the product life cycle:

  • Sales Forecast: Sales indicates the product’s lifespan. Improving sales maximizes the life cycle of a product.
  • Effective Planning: Once the company can predict sales performance, it becomes easier to plan and implement strategies that benefit the company in the long run.
  • Competitive Advantage: The product life cycle helps companies compete effectively since the stage of the product is identified. And then, you can implement a set of strategies accordingly.
  • Decision Making: The product life cycle can help the company make crucial decisions related to product development. The essential choices include upgrades, improvement, and additional features.
  • Target Audience: The product life cycle helps target the right audience and identifies if the product meets their needs. In case of decreased sales, you can also determine the focus-reshifting of the target population.

5 Stages of the Product Life Cycle

5 Stages of a Product Life Cycle

The product life cycle unfolds in five stages – Development, Introduction, Growth, Maturity, and Decline. Every stage is distinct, with costs, risks, and opportunities they bring.

We will also look at an example under every stage for better understanding.

Stage 1: Development

This is the stage in which a new product is conceptualized and developed. During this stage, a company will invest in research and development to create a product that meets the needs of its target market. The two phases under the Development stage are:

  • Design and Prototyping Phase: During this stage, Tesla’s engineers and designers worked to create a design for the Model S. Prototypes of the car were built to test its performance, reliability, and safety features.

Development is when the cost of production keeps on rising while there is no revenue generated. 

Some products require years of research and tons of capital investment. And others are quicker to develop and launch in the market.

At this stage of the product lifecycle, the risk is very high. Hence, funding is limited

Thus, many companies use the strategy to direct the revenue generated from their current products toward investing in another startup.

Stage 2: Introduction

The introduction is when the product development has almost reached its end, and it’s time to market the product and create awareness about its launch. 

Unlike the previous stage, the marketing costs are higher in this product lifecycle stage. It becomes crucial to reach out to potential clients and customers. There are two phases under this stage:

  • Market testing and launch phase: Prior to the launch of the iPhone, Apple conducted extensive market research to test the product and gauge interest from potential customers. The iPhone was then officially launched and made available for purchase.
  • Early adopter phase: During this stage, the iPhone was primarily adopted by early adopters and technology enthusiasts. Sales were modest but growing, as people became more familiar with the product and its features.

Marketing strategies during the introduction stage: Apple included high-profile advertising campaigns, demonstrations in Apple retail stores, and strategic partnerships with major carriers.

Stage 3: Growth

At this stage, customers finally welcome the product. 

Your business competes to increase its market share because other companies know your product and its place in the market.

If there are many competitors, your product’s price is likely less. However, suppose your product is innovative with lesser competition. In such scenarios, the prices of your product may remain high for a longer time.

  • Mass Market Adoption Phase: The smartphone industry saw mass market adoption in the late 2000s and early 2010s. This was largely due to the increasing affordability of the devices and the widespread availability of mobile internet access.
  • Expansion of Product Offerings: Manufacturers began to offer phones in different sizes, with varying levels of processing power and storage capacity, and with different operating systems.

Marketing Strategies: Smartphone manufacturers ran extensive advertising campaigns in traditional media such as television, print, and outdoor advertising, as well as in digital media such as online advertisements, social media, and email marketing.

Stage 4: Maturity

Maturity is the stage of the product lifecycle where your sales will slow down or, in some cases, even stop. It results from increased competition to maintain your market share and saturation.

We call this the ‘shake-off point,’ when less successful competitors exit the market.

Companies will likely alter or develop a new product to cater to different consumer needs. You strategically use innovation to modify the product and maintain the market share.

Prices are likely to decline to meet high competition. Production costs have decreased due to higher efficiency. You don’t require additional funding at this stage.

  • Stabilization of Sales and Market Share: During the Maturity stage, the sales of personal computers stabilized, as the market became saturated and the demand for new computers began to level off.
  • Cost-cutting and Product Improvement Phase: In response to the stabilization of sales, PC manufacturers began to focus on cost-cutting and product improvement. This involved streamlining their operations, reducing the cost of materials and components, and improving the efficiency of their manufacturing processes. 
  • Marketing strategies: During this stage, PC manufacturers shifted their marketing strategies away from the aggressive tactics they used during the Growth stage. Instead, they focused on promoting the reliability and affordability of their products, and on differentiating themselves from their competitors. 

Stage 5: Decline

The product lifecycle stage is associated with a decline in revenue, resulting from several factors.

Factors include market saturation, increased competition, decreased demand, technological evolution, or changing user needs.

  • Decreasing Sales and Market Share: During the Decline stage, the sales of floppy disks rapidly declined as newer and more advanced storage technologies became available. As a result, their market share also declined, as customers turned to other options such as USB drives and cloud storage.
  • Phasing out and Retirement of the Product: In response to the decreasing sales and market share, manufacturers of floppy disks began to phase out the production of the product. This involved reducing the number of factories producing floppy disks and gradually discontinuing the production of the product altogether.
  • Marketing strategies: During this stage, the strategies for floppy disks shifted from promotion to liquidation. This involved heavily discounting the product to clear inventory, and promoting its retirement to encourage customers to switch to newer technologies. 

Factors Affecting the Product Life Cycle


The level of competition in the market can impact the rate at which a product moves through each stage of the lifecycle. 

For example, a product that is in a highly competitive market may see its sales decline more rapidly than a product in a less one.

Consumer Preferences and Behavior

Changes in consumer preferences can impact the demand for a product, and shifts in the consumer behavior can impact the way that customers use and purchase the product. 

For example, if a product becomes outdated or less popular, it may see its sales decline, even if there is no direct competition.

Technological advancements

New technologies can create new products and make existing products obsolete. 

For example, the advent of digital storage technologies has led to the decline of the floppy disk.

Economic factors

Economic factors, such as changes in the overall economy, shifts in consumer spending patterns, and changes in the cost of materials and labor, can also impact the product lifecycle. 

For example, a recession may lead to a decline in consumer spending, and a decrease in demand for a product.

Overall, these factors interact and can impact each other, making the product lifecycle a complex and dynamic process that is subject to change. 

Managing the Product Life Cycle

Managing the product lifecycle involves understanding the stage that a product is in and adapting marketing and management strategies accordingly.

The following are steps companies can take to effectively manage the product lifecycle:

Identifying the Stage of the Product Lifecycle

The first step in managing the product lifecycle is to accurately identify the stage that the product is in. You can do this by analyzing sales trends, market share, customer feedback, and other data to determine what stage the product is in. 

Adjusting marketing strategies based on the stage of the product lifecycle

Once you identify the stages, you can then adjust the marketing strategies accordingly. For example, during the Introduction stage, companies may focus on building brand awareness and generating initial sales. During the Growth stage, they may focus on expanding their product offerings and increasing market share, and so on. 

Planning for product retirement

Effective management of the product lifecycle also involves planning for the retirement of a product. This may involve phasing out the production of the product, discontinuing its marketing, and managing the transition to new products or technologies.

By planning for the retirement of a product, companies can minimize the risk of stranded inventory and ensure a smooth transition for their customers.

Overall, by understanding the stage of the product lifecycle, companies can maximize the success and profitability of their products and ensure their long-term success in the market.


A product lifecycle is a crucial tool in today’s market as it helps companies understand and manage the stages of a product’s development, from ideation to discontinuation. 

By analyzing the lifecycle, businesses can make informed decisions about investment, marketing strategies, and resource allocation, leading to greater efficiency and profitability.
