The Indian IT industry refers to the information technology located in India. The IT industry includes the services relating to informational technology as well as the outsourcing. It is always hard to determine what will happen in the future even the recent future. However you can make an educated guess based on the past history of this industry. For the Indian IT industry they grew in revenue from 2012 to 2017.
Therefore I expect this industry to continue growing. If it doesn’t grow I believe that it will plateau but I don’t think that it will decrease. Some people believe that this industry in India will be the biggest in the world in just a few years compared to the other countries.
