Competitive environment

The first and the easiest way of comparing to companies with each other are to compare their income and the amount of their buyers. Then the location is so important; for example in compare of to shop which one is in city and the other one is in the country, the city one usually is more successful. 

For example in compare of Nokia phones and Android or Apple iphones, Noki’s sale is rapidly going down. cause those are better quality, brand new, more beautiful and has more interesting animation while working with them, so people prefer to buy those ones more.

the social environment in Iran

Nowadays, the role of parents especially father in the family has changed from making lots of children to making more money and less children, like two or three. For example in Iran, changes in size and distribution of population have exerted a profound influence on the recent economic and social development and will be even more influential in the coming decades. The vast movement of the rural youth to urban areas affected the 1978-79 social upheavals, as did the youthfulness of the population affect the rise of the democratic reform movement which started with President Khatami's election in 1997.
