Use all the ideas submitted here that are good! Hopefully you have a system of selecting all good ideas and sending them to the appropriate agency, not just the 1 or 2 top winners? It would be a waste of our time as well as a lost opportunity to use the good ideas if all were discarded except the top winner. Although the criteria for 'top winner' aren't posted, presumably the winner is one that saves the most money, minus the cost of implementing it. But it's likely that many good ideas will be submitted that would make processes more efficient or save some lesser amount of money, and these should be implemented, too. Those who submit the ideas would be content with a thank you letter from the head of their department.
