A few drips of water are fairly non-threatening. Rarely can a drip or two wash people or cars away or change the flow of a river. Constricting the flow of water harnesses a great deal of potential energy that when released can be used to generate power if it is run through a turbine or if released randomly the impact might be difficult to control.
Develop a backlog of potential changes and keep the list prioritized so that the effort you have to affect change can be channeled for greatest value. A backlog of process improvements is very much like the dam that collects the drips of water until it can drive the turbine of change. Like the dam if it is always collecting and never being relieved it burst and change will happen in a much less controlled manner.
