There are a large number of similarities between the curriculum of both MBA and PGDM. An MBA institute follows a fixed curriculum as it will be based on the university guidelines which occasionally may not be aligned to industry requirements. Autonomous institutes do not follow university standards, so it is have the flexibility to align its curriculum according to industry standards and change in the business environment. Some of the PGDM from IIMs, XLRI etc has more value then MBA. However MBA of FMS DU, IIFT etc have similar value as IIMs. Students are advised to chose Institute based on its ranking not on nomenclature of degree.
