The Learn, Innovate, Improve (or, LI²) process is a way for human services leaders to intentionally launch and systematically guide program change and to incorporate evidence and research methods into such efforts. This practice brief provides an overview of the first phase of LI²—the Learn phase—which is intended to lay the foundation for successful and sustainable program changes. The Learn phase involves two primary steps: (1) clarifying the reason for seeking change and the problem to be addressed, and (2) assessing the program environment’s readiness for change.
