In a telephone company, it is said "Bring a telephone within the reach of every person in the country". Is it 1-Plan 2-Strategy 3-Vision 4-Mission?

i love to see it as a mission. 

I see that this is the company's vision.

its vision of the company.

Its company's vision.

The statement is a vision of what  the telephone company would like to achieve, it is a stretch goal and most likely will never be attained.

Its the dream the vision. The mission will be the means to achieve the vision. Mission is a long term goal such as in 10 years time where the company want to be. Goals are short term specific results the company wants to achieve in order to reach the mission in the long run. Strategies are the mean by which the goals are achieved.

For me, its a growth plan or a strategy for the company itself but how they publicize it is - a vision. So, basically it is a marketing tactic in the disguise of company's vision for the well being of public!

Well, at least that is how I see it.
