It depends on the risks involved and the rewards of the project idea. How much funding is needed how much is the potential for the success also the time frame of the completion of the project idea. If the project has better benefits and improves the life, then in my opinion dropping the project is not a good idea if the project idea is beneficial for the future and can be patented then company should go with the project idea. There are many ways to get the funding one of which is a crowdfunding or angel investors.
