For our well project, the model might be something like this: we plan our resources (the people, materials, money, and other things we need), we undertake a set of activities (traveling to the village, acquiring and transporting our materials, building a well). If all of this goes according to plan, we create the output—the well. If the well works as planned, we achieve our outcome—people in the village spend less time carrying water. That in turn, becomes an important contributor to the impact we seek: a higher standard of living in the village.
