PLC is a series of stages that products passthrough in their lifetime, characterized bychanging product demands over time.
There are typically four stages of the product
life cycle: introduction, growth, maturity,and decline
Products in the introductorystage are notwell defined and neither is their market.
Often all the bugs have not been workedout and customers are uncertain about theproduct

In the growth stage, the product takes holdand both product and market continue to berefined
The third stage is that ofmaturity, where
demand levels off and there are usually nodesign changes: The product is predictableat this stage and so is its market.
Many products, such as toothpaste, can stay
in this stage for many years. Finally, there is a decline in demand,
because of new technology, better productdesign, or market saturation

The first two stages of the life cycle cancollectively be called the early stages of theproduct life cycle because the product is stillbeing improved and refined, and the market
is still in the process of being developed. The last two stages of the life cycle can be
referred to as the later stages because herethe product and market are both well
defined.

Understanding the stages of the product lifecycle is important for product designpurposes, such as knowing at which stage tofocus on design changes.
Also, when considering a new product, theexpected length of the life cycle is critical inorder to estimate future profitability relativeto the initial investment.

The product life cycle can be quite short forcertain products, as seen in the computerindustry. For other products it can beextremely long, as in the aircraft industry.
A few products, such as paper, pencils,nails, milk, sugar, and flour, do not gothrough a life cycle. However, almost allproducts do, and some may spend a long
time in one stage.
