Billions of dollars are invested annually in leadership development globally; however, few programs are evidence-based, risking adverse outcomes, and wasted time and money. This article describes the novel Inspire Nursing Leadership Program (INLP) and the outcomes-based process of incorporating gold standard evidence into its design, delivery, and evaluation. The INLP design was informed by a needs analysis, research evidence, and by nursing, Indigenous, and equity, diversity, and inclusion experts. The program's goals include enabling participants to develop leadership capabilities, cultivate strategic community partnerships, lead innovation projects, and connect with colleagues. Design features include an outcomes-based approach, the LEADS framework, and alignment with the principles of adult learning. Components include leadership impact projects, 360-assessments, blended interactive sessions, coaching, mentoring, and application and reflection exercises. The evaluation framework and subsequent proposed research design align to top-quality standards. Healthcare leadership programs must be evidence-based to support leaders in improving and transforming health systems.
