A new product is introduced to the market, and it goes through a period of growth
in market demand and profitability. The market then ‘matures’ and sales stop
growing. Eventually, the market declines and sales fall: the product becomes
unprofitable and production is ended. The life of a product can be made longer, by
re-designing the product regularly, and through advertising and other marketing
methods.
The length of a product life cycle varies. As a general rule:
a broad type of product may have a long life of several decades
the product may be produced in several different forms, and the life cycle of
each form of the product may be shorter than the total life of the broad product
companies may produce a form of the product, and the life cycle of a company’s
product may be shorter than the total life of broad product form.
For example, the life of the television has already been many decades long, and
shows no obvious sign of coming to an end. However, the life cycle of the black-
and-white picture television set has been shorter, and the end of the life of the
analogue television can now be foreseen. Many companies have produced black and
white picture televisions in the past, but the life cycle of their particular product will
often have been quite short. For example, some companies may have stopped
producing black and white televisions and switched entirely to colour televisions,
long before other manufacturers stopped making black and white televisions. There
is now a possibility that internet-based video systems will eventually replace the
‘traditional’ television.
As some products of a company reach the end of their life cycle, they need to be
replaced with new products. Product innovation is essential to survival. Companies
need to have a portfolio of products that:
provides a profit, and also
ensures the survival of the company’s business in the longer term.
1.2 Financial aspects of the product life cycle
As explained earlier, the ‘traditional’ product life cycle has four phases:
introduction, growth, maturity and finally, decline. At each phase in its life cycle:
selling prices will be altered
costs may differ
the amount invested (capital investment) may vary
spending on advertising and other marketing activities may change.
Sales volume, sales revenue, profitability, investment and cash flow will all vary as
the product goes through the different stages of its life.
