Narendra Modi's first cabinet reshuffle

Instead of going into names of Ministers, their castes and regional backgrounds, it might be better to have a general over-view of the positives of Cabinet expansion and the limitations that Narendra Modi faced. Barely 5 months have passed and Prime Minister Modi had to go in for a major re-shuffle of his cabinet. There is nothing wrong for a Prime minister in a parliamentary system of government to re-shuffle or expand his cabinet. It is obvious that in the last 5 months some weaknesses have become obvious in the functioning of the government. The existing cabinet was in-adequate both in numbers  and quality to deal with the problems.
