Question: What is the difference between *make decision* and *take decision*? When to use the one and when the other?

Answer: 
Actually, I think the difference between the two is the final action.

Making a decision implies something you have decided in your mind. The action to implement that decision may or may not have happened.

Taking a decision implies that the action to implement the decision has happened. 

That's my two cents worth.
making a decision is something you have engineered; taking a decision is something that is put before you (active versus passive).
