Prototyping allows instructional designers to streamline the design process by creating early versions of parts of an elearning project to test design concepts and functionality before building out the full project. This allows designers to receive feedback and make revisions early in the process rather than late in the project timeline. Prototyping can improve estimates, encourage creativity, incorporate feedback flexibly, and integrate quality assurance testing more seamlessly. The presenter provides examples of how prototyping can shorten timelines and relieve end-of-project pressure compared to developing a full project without prototyping. Steps for prototyping include creating micro and full prototypes to obtain approvals before full replication.
