Among the mentioned programs PGDMM and PGDPM are comparatively newer and provide some really good courses for students with computer and IT backgrounds. If you want to take the GATE exam and get into NITIE through PGDIE then in the 2nd year of your course you will get a wide range of electives available. Here are some of the electives. 

• Advanced IT for Industrial and Manufacturing Engineering
• Business Process Integration and Management
• Computer Integrated Manufacturing
• Data Analysis and Decision Making
• Data Analytics
• Data Communications and Networking
• Data Mining for Business Intelligence
• Decision Support Systems and Expert Systems
• E commerce
• E customer Relationship Management
• ERP, etc. 

Most of the courses here are Computer sector-related and related to the programming and software side whereas some of them are related to the IT sector and mainly deal with the hardware side. 

But make a note that IE is not an M.Tech course. It is a management course. So, you will get placed in management roles post your degree.
