ADDIE is a traditional instructional design process that emphasizes upfront analysis, design and development of the learning, followed by piloting and evaluation. Now that e-learning is increasing prevalent, waiting to test a program after everything
is developed can result costly changes and time delays. So we’re now seeing the emergence of models that are more agile such as SAM. SAM stands for Successive Approximation Method and enables the professional to test
their course sooner. The steps in SAM are to Evaluate first, then Design and Develop the course, then repeat the process
by Evaluating the first iteration of the course.
