#growth #productdevelopment Melinda Gates talks about how critical it is for the Gates Foundation to define the right [[Interfaces|interface]] in her book, [The Moment of Lift](https://www.amazon.com/Moment-Lift-Empowering-Women-Changes/dp/1250313570), when she described delivery systems. > Delivery systems matter. What do I mean by a "delivery system"? 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. — Melinda Gates When the Gates Foundation figures out what delivery system to use to provide life-changing information and products, they are identifying the interface they will use to talk to their audience. It's hard work, it's nuanced, and it requires exquisite listening skills. In the example above, Melinda Gates is talking about the way the Gates foundation encourages people to use the tools they bring to them, but delivery systems matter every day of our lives. Delivery systems are really about the ways that we communicate with one another, whether its through a book, a blog, a conversation, a song, or hundreds of other mediums. When we create an effective delivery system to deliver information, the results are often astounding. By recognizing all of the different delivery systems around us, we can start to draw connections between them ([[Processes + Conditionals Lead to Actionable Knowledge|which systems work in which situations]]) that allow us to create more effective delivery systems for the things we want to communicate to the world.
