what is the biggest shortcoming of India??

Well, corruption came first but actually real problem with India these days is lack of being organized and structured operations.

any other reliable shortcomings??

how it can be improved??

What we lack is a real body or department which should work on improving efficiency of the work we do .

Like in big companies we have R&D and creative department, India too need such type of system which should work to improve efficiency as well eradicate anomaly of the way we work in India !

eg. Every other day Govt. sanctions 100 of crores for development, improvements and other works but do they really get utilized ? As per general assumptions, only 20-30% get used for actual purpose, rest is eaten by corruption, now if there is a way or team which can think upon a way to create a way of working which minimalize chances of corruption then things can turn beautiful.

Another example, almost all dept of India lacks co-ordination with each other, be it securities or city development, you may have seen many times that a new built road is spoiled by Water Dept. just because Municipal and Water Dept had no co-ordination.

So, as per my view, India need some way to make itself organize and efficient.
