The Product Life Cycle of Engineered Metals: A Comparative Analysis of the Application of Product Life Cycle Theory

Examines the use of Product Life Cycle (PLC) in analyzing the rise and fall in product demand. Applies the cycle stages: product development, introduction, growth, maturity, decline to the demand behaviour of industrial materials such as steel, aluminium, titanium. Relates the demand pattern of the Gross Domestic Product and the relative development of the national economy, e.g. USA. Concludes that the PLC invariably parallels the GDP.
