Stages of a products life cycle

Product life cycle
  • The introduction, evolution/growth, decline and replacement cycle of products
  • Using the product life cycle, companies project sales from introduction to withdrawl, they plan the decline and replacement stage carefully



Introduction:
  • The product is launched with appropriate publicity following market research and sales start to take off (increase)



Evolution/growth:
  • Advertising helps product sales to grow as consumers move to this product from previous ones



Maturity:
  • It is important to keep the product in this period of peak sales for as long as possible



Decline/removal:
  • Consumers who wish to buy will have done so and the product is eventually withdrawn

Extensions/replacements:
  • Updated, improved version is released to maintain sales
