At my personal level i think MBA ia necessary before joinng 
any organization because it give vast knowledge of working 
of the organization structure and enables or inserts 
necessary skills required for an employee to perform work 
in the org. It may be in the department of Finance, 
Humanresource, Marketing or any of the related departments.

it reduces timeframe required to achieve monetary success 
in life

in my view i need an MBA because after working as a fresher 
in a firm as a sales engineer i felt an mba degree would 
help me understand sales and marketing in an organisation 
at a much better level, it would enlighten me with not only 
learning skills but also let me understand what i am doing 
right now better thereby help me acheive my dream of 
opening a consultany later in life

to become specilisation in any one of the field i mean 
either in finance, marketing, hr, or in it . so that we can 
enter the globle business world in any one of the 
specilist . so we can contribute  better in achiveing the 
organizational goal . at the same time we r obtaing 
business skill and master degree

I want to do an MBA because, I want to learn to manage
business efficiently. To manage a business there is
requirement of skills which one can get through a very long
period of time.But the same skills one can learn in an MBA
college. The professor who teaching in MBA college learns
from  there past experience which are very useful. Instead
of getting the initial skills from practical experience
which would take enough time, it would be better you get
those skills from an MBA.

It gives an integrated thought precess ability to interlink 
many facets of business and helps him take effective and 
efficient decisions in an organisation / firm in which he 
will join as Manager.
