  2. Product sales pass through distinct stages, each posting different challenges, opportunities and problems to the seller

(1) Introduction stage:

In this stage the product is new and the customer acceptance is low and hence the sales are low.

(2) Growth stage:

Knowledge of the product and its capabilities reaches to a growing number of customers.

(3) Maturity stage:

The product is widely acceptable and sales are now stable, and it grows with the same rate as the economy as a whole grows.

(4) Decline stage:

At some point of time the product enters the decline stage. Its sales start decreasing because of a new and a better product has entered the market to fulfill the same customer requirements.

After a lot of research Nokia then launched it’s first phone without an antenna, Nokia 3210 on March 18, 1999. With more than 160 million units sold this model is one of the most popular and successful phones in history. When I-phone and Samsung came in competition, Nokia then launched phones like N95 to compete with them.


During this stage, Nokia launched a lot of touch screen models, one of which was N-97 qwerty+touch which was huge success and the most profit was gained.


Nokia’s poor product design and having it’s main focus on Windows as it’s OS, lead to it’s decline. Nokia is going through this stage now.
