Hello there ,, im a little confused about this , this buisness school ( Swiss buissness School ) was recommended by one of my friends to enroll myMBA into , so

Is this buissness school , recognised , well reputed , accredited as an MBA institute .

is their swiss accreditation well recognised in europe , uk , us or middle east

SBS is not accredited as a degree-awarding institute in Switzerland (or, as far as I know, by any other government). It is an adult education provider, with a similar status to a language school. It has none of the three respected MBA acreditions.

There is some more discussion here:

In general, it's advised to steer clear of this kind of organization. For business schools in Switzerland, stick to those accredited by AMBA, EQUIS, or AACSB. IMD, St. Gallen, HEC Lausanne, etc.

If someone is looking at SBS they are almost certainly not planning to study in Switzerland. They are more likely to be in the middle East or central Asia.
