"Getting tools to people who need them in ways that encourage people to use them -- that is a delivery system. It is crucial, and it is often complex. It can require getting around barriers of poverty, distance, ignorance, doubt, stigma, and religious and gender bias. It means listening to people, learning what they want, what they're doing, what they believe, and what barriers they face. It means paying attention to how people live their lives. That's what you need to do if you have a life-saving tool or technique you want to deliver to people."
