Sustaining transformational change requires focusing on sustainability to avoid constantly reinventing projects and address changing funding priorities. Project sustainability means maintaining and enhancing goals/outcomes by embedding them in people through expertise/knowledge, processes through policy/strategy, and tools/resources. Embedding requires considering factors like outputs, innovation, processes, and communities of practice. Sustaining projects involves developing a vision/plan, identifying stakeholders, communicating benefits, and ensuring resources remain accessible over time. Key challenges include identifying outcomes to sustain and gaining support to embed changes institutionally.
