  • Example: Launch of a new electric vehicle model.

2. Growth Stage

In this stage, the product becomes popular and sales increase rapidly.

  • Characteristics: Rapid increase in sales, increase in profits, more competitors enter the market, and improvement in product quality.
  • Objectives: Increase market share, improve product features, and expand distribution channels.
  • Example: Rapid growth of smartwatches.

3. Maturity Stage

This stage represents the peak of product acceptance in the market.

  • Characteristics: Sales reach maximum level, market becomes saturated, heavy competition, and profit begins to stabilize.
  • Objectives: Maintain market position, reduce production cost, and differentiate product from competitors.
  • Example: Soft drinks and toothpaste brands.

4. Decline Stage

In this stage, sales and profits start decreasing.

  • Characteristics: Reduced demand, technological changes, changing customer preferences, and falling profits.
  • Objectives: Reduce unnecessary costs, improve product, or discontinue it.
