I’ve found it really helpful to communicate and train funders to learn how to watch software being built. It takes time to teach someone to look at builds and tests and growing code and activity and demo releases. It also takes time to teach developers not to game this.
It’s amazing how much this helps build trust. It’s hard when there truly are big giant components that take a long time between commits and builds. But I think those are much rarer than programmers think and say.
