The document outlines five strategies for libraries to adopt startup thinking: 1) Focus on understanding the problem from the user's perspective, 2) Build products for specific user groups, 3) Take an iterative "build-measure-learn" approach to product development, 4) Closely monitor key metrics to track impact, and 5) Clearly articulate the value created for each user group. The strategies are meant to help libraries operate more innovatively with limited resources in an environment of uncertainty and change.
