I have an Industrial Engineering background and have used optimality solutions. The biggest hurdle I've found with "selling" optimality solutions is explaining the benefit. While it is great to show the technical and optimal savings it isn't always clear to the final user of the solution.
The best way to "sell" the solution is to translate it to real savings that the end user understands. For instance if it is a public municipality show them how much time is saved to open up resources. For private institutions show them how much money is saved that will improve profits or reduce costs.
