This document discusses the art and science of learning and development (L&D) design. It states that L&D design is both an art and a science. The artistic side involves creatively designing learning journeys that engage learners through innovative activities and methods. The scientific side requires defining goals, scopes, and outcomes and discovering learner needs through research to ensure solutions are effective. An ideal L&D design blends both approaches to create learning experiences that are practical, relevant, measurable, and facilitate immediate knowledge transfer.
