The MA ODCL is a unique 2-year full-time program offered by the School of Management and Labour Studies at TISS. It is a first full-time course in Organisation Development and tailor-made for aspirants willing to have a learn and grow in the field Organisation Development and the students regularly interact with senior industry professionals through Masterclass sessions every week and are exposed to business insights by C-Suite leaders through odX sessions every month. It is a very niche course and if you are unsure about the specialization you'll pursue in future, then it is better to go for SIBM Pune.
Choose wisely. All the best!
Based on the course structure, which appears to be very similar, SIBM Pune will definitely be a much better choice for you.
However, I can't comment on the RoI of the institute since TISS only discloses the fee of the programme on request. You can mail them here.
InsideIIM has a great article describing the TISS ODCL programme and campus life. You can read that here.
