Bureaucrats take the actions which are justifiable (by book or by order of their superiors), they care less about consequences (in case there are multiple possible actions, they let the politician decide the appropriate action).
Technocrats take the actions which (according to their analysis) have best (long term/short term) consequences, they care less about how harsh the action could be on certain individuals and their logical thinking usually fails to take into account the law of unintended consequences like Cobra Effect.
Politicians take the actions which are palatable and which are usually good for their (long term/short term, well, usually for next elections) popularity.
Till now, India was run primarily by politicians + bureaucrats, it seems to be transitioning towards politicians + technocrats.
It would be interesting to see the (short term/long term) consequences of this transition.
Note: The above statements are not my original discovery, I have read statements along similar lines at various sources.
