For some reason instructional designers love building ADDIE into a goddess that orders them to build crappy learning platforms. For example, they pronounce that it only builds courses when the real fact is that it tells you to use a course only if a simpler method, such as a performance support tool or OJT, will not work.
Excellent post from Donald. Don’t use models as a crutch to support your crappy design. It is up to you, the designer, to actually design something. Don’t blame ADDIE, or any other model, for your failures as a designer.
