LIFE CYCLE ASSESSMENT LESSON 3 Within this lesson you will cover: Understand the life cycle of a product through a graph. Understand the role of planned obsolesce in relation to the benefit of the manufacturer and not necessarily the consumer. Apply knowledge by comparing two similar products and answering an exam question.

WHAT IS A PRODUCT LIFE CYCLE? Objective - Learner will gain knowledge & understanding of the role of planned obsolesce in relation to life cycle assessments. WHAT IS A PRODUCT LIFE CYCLE? The diagram below helps shows the life cycle of specific products. Fad – A product that is popular for a short period of time. Standard – A product that is used regularly and very rarely changes. Classic – A product that is timeless and has been adapted over time but still remains to have the same principle. Planned obsolescence can be regarded as bad for the environment, because it leads to products being ‘dumped’ by customers, so that new updated products can be acquired. The product is becoming more well known and wanted. The product is at its peak of sales. The product is becoming more well known The product is launched in shops, displayed, advertised. Planned obsolescence

WHAT IS PLANNED OBSOLESCENCE? Objective - Learner will gain knowledge & understanding of the role of planned obsolesce in relation to life cycle assessments. WHAT IS PLANNED OBSOLESCENCE? Planned, obsolescence is the description given to something that has been designed to have a limited working life. Manufacturers may accelerate the obsolescence of a product by introducing new, more desirable products or versions of the existing product. E.g.

(Q) Looking at the diagram what differences do you see? Objective - Learner will gain knowledge & understanding of the role of planned obsolesce in relation to life cycle assessments. WHAT IS PLANNED OBSOLESCENCE? Planned obsolescence is sometimes designed into a product, in order to encourage the customer to buy the next upgrade. A good example of this is a mobile phone, such as the IPhone. (Q) Looking at the diagram what differences do you see?

Life cycle analysis of games consoles Objective - Learner will gain knowledge & understanding of the role of planned obsolesce in relation to life cycle assessments. PRODUCT LIFE CYCLE GRAPH TASK Life cycle analysis of games consoles Study the graphic and select one games console which you can convert into a life cycle analysis graph.

CONVERTING DATA INTO A GRAPH Objective - Learner will gain knowledge & understanding of the role of planned obsolesce in relation to life cycle assessments. CONVERTING DATA INTO A GRAPH On the worksheet provided write a short definition of what a product life cycle graph is. On the graph paper template using a ruler and pencil I would like you to draw a product life cycle for one of the products previously seen on the graph. Label the graph A, B,C & D. Introduction [A], Growth [B] Maturity [C] & Decline [D]
