The ADDIE model was created to manage the instructional process for Analyzing, Designing, Developing, Implementing, and Evaluating instruction.  The ADDIE model is a set of comprehensive guidelines, tools, and techniques needed to close the gap between current and desired job performance through instructional intervention.  ADDIE is a flexible, outcome-oriented system based on the requirements defined by education and training. The ADDIE process reduces the number of school management decisions that should be made subjectively and, instead, allows decisions to be made based on reasonable conclusions which are based on carefully collected and analyzed data.
