In any sphere of human activity, success requires focused effort and specialization. Socrates makes the point in Plato’s Republic, written around 360 BCE. People and organizations should do more of what they do best, yet nonprofit organizations working in international development are often unfocused and unspecialized. Defining focus is the most crucial strategic set of decisions that an organization takes, but nonprofits face formidable incentives to lose focus. This paper argues that if organizations are interested in achieving high and measurable performance, they need to resist the temptation to drift and take deliberate and regular steps to focus and refocus.
