Sustaining program

A sustaining program is something that helps to keep things going over a long period of time. Let's say you have a toy car that needs a battery to run. You put a new battery in and the car runs well, but you need to change the battery every so often to keep it going. A sustaining program is like changing the battery for the toy car. It makes sure that what needs to be done to keep something going is done regularly and properly. This can apply to things like businesses or organizations, where there are lots of moving parts and different people involved. A sustaining program helps to make sure that everyone is doing their part and things keep running smoothly. It's kind of like a plan that is put in place to make sure that things don't fall apart, and everything stays on track.
