I think that SAM is a very direct way to get the Stakeholders, SME's and developers on the same page. Everyone is basically notified that while the project is in development, their timely feedback is important to creating the best module, with the least amount of setbacks, almost like creating constantly evolving design period for the entire project.
Working on the entire project (SAM) in a program like Articulate, instead of a module at a time (ADDIE), is way more efficient, because changes can be made almost instantaneously. It seems to give the Stakeholders and SMEs more of a sense of ownership in the project, too, urging them to be more responsive and vocal on the things that matter without having the financial burden of the setback.
(By the way, I agree about the bad wrap PowerPoint is given. People blame the tool instead of the material in my mind.)
