"Feasibility" means the convenience and ease of doing something. If it is reasonable to do or make something, then you can say it is feasible. If it is too costly or difficult, then it is not feasible. When referring to a new product this means that the product would be profitable to produce. For example, at one time electric cars were not feasible simply because gas-powered cars were cheaper and easier to make. Now, however, electric cars are feasible because of improved technology for electric cars.

It means usability.
