1. [5.5] Product Life Cycle Essential idea: There are several key stages in the product life cycle Nature of Design: Designers need to consider the whole product cycle of potential products, services and systems throughout the design cycle and beyond. Products may have an impact not only on the direct consumer but also on society at large and the environment.

2. Key stages of the Product Life Cycle: Launch, Growth, Maturity, Decline Although the designer is an integral part of the process, he or she is not necessarily in control (unlike in the design process).

3. Introduction / Launch Phase: necessary to launch the product with the right image and at the right price. needs infrastructure / distribution to support new product requires significant investment.

4. Growth Phase: when sales are increasing at their fastest rate. the market has accepted the product and sales begin to increase.

5. Maturity: sales are near their highest, but the rate of growth is slowing down, e.g. new competitors in market or saturation.

6. Decline Phase: Decline – final stage of the cycle, when sales begin to fall

7. Decline Phase: Decline – Could the product be re-launched? Does the product need modifying? Is a new product needed? Is it time to move on? Is a new market needed?

8. Shorter Product Life Cycles Why?

9. Products at different stages of the life cycle

10. Extending the Product Life Cycle Extension strategies extend the life of the product before it goes into decline. Again businesses use marketing techniques to improve sales What strategies might a company use to extend the life cycle of their product?

11. Extending the Product Life Cycle Advertising – try to gain a new audience or remind the current audience Price reduction – more attractive to customers Product versioning Explore new markets – selling the product into new geographical areas or creating a version targeted at different segments New packaging – brightening up old packaging or subtle changes

13. Obsolescence Planned obsolescence or built-in obsolescence is a policy of planning or designing a product with an artificially limited useful life

14. Obsolescence - Style (Fashion) Planned obsolescence or built-in obsolescence is a policy of planning or designing a product with an artificially limited useful life

15. Obsolescence- Functional obsolescence Particular items may become functionally obsolete when they do not function in the manner that they did when they were created

16. Obsolescence - Planned obsolescence the objective of generating long-term sales volume by reducing the time between repeat purchases

17. Obsolescence - Technological usually occurs when a new product or technology supersedes the old

18. Obsolescence - Advantages Manufacturers can sell more products Stimulates demand More control over demand Can influence a company's decisions about product engineering - use the least expensive components

19. Obsolescence - Disadvantages Potential backlash of consumers Ethics Creates more waste, pollution, uses more natural resources, and results in more consumer spending.
