Online learning continues to grow at unprecedented rates. However, despite this unprecedented growth, there is little research on model formation and model validation for online learning. Two research-based models were created: eSUCCESS and R2D2/C3PO to help project managers, instructional designers, and developers design and implement online learning solutions. Both of these models were created based on research findings using qualitative case study and design and development case study guidelines. The purpose of this descriptive qualitative study was to describe the process of model creation for both models and to systematically validate the two models using a survey and the nominal group technique (NGT) with expert instructional designers.
