The time involved in processing of licences and related matters is simply unacceptable. You cannot expect to be in the aviation industry and be lax about punctuality and timing. By the time we wait around 4 to 6 months for one rating, exam result or endorsement to come through, we would have missed the bus, so to speak.
Issue of licence, ratings, exam credits etc should take no more than 48 hours from the time of submission of the application. If they are short of manpower, let them hire more employees. Simple as that. Afterall, they are make us pay through the nose for services. India is full of unemployed graduates, let them take on board a few thousands of them to get our work done on time and in an efficient manner.
Otherwise, outsource the DGCA to Australia/NZ/USA
