3 better ways to kill an idea

Suppose we are in the government or a financial institution and the like where we can give grants or loans to support various projects. People come to us with ideas and hope in the form of a proposal.  There are 3 easy and better ways of killing such proposals. First, start with 'not possible', no budget or funds or we never dealt with the proposer. Second, try to straightjacket them in the existing templates or guidelines or products which anyway may not fit if it is not a run of the mill kind and the proposer has original idea. Also, his intention may not be to just get some fund but pursue his idea. Third, if he expects a blazer offer him lungi as you have only lungis in stock.
If we have to just dispense with funds and incentives mechanically, we donot need humans. Just install interactive interfaces or portals like irctc. Just enter details, you get tickets. Life's situations are not simple and straight. Umpteen possibilities exist for humans to explore.
Often, we find it difficult to appreciate new ideas. Our brians are wired to accept known things. Risk averse. I remember what a banker said about the first private port (Pipavav, Gujarat) founder, Mr.Nikhil Gandhi, that his ideas are ahead of times and could not be accepted by bankers. He created history.
Often investors do want to support only the successful people, however powerful the ideas of gonna be successful people. Also, funders want three years track record. Its like insisting on job experience for giving job whereas someone need to give job for the candidate to get necessary experience.  Solutions are not very difficult if we go by the spirit and not just letter. Bring human element into the decision process while interpreting the guidelines than being mechanical. Guidelines, one must respect though, are for average situations and cannot fit all situations to come.
