The metaphor I have heard is as follows:
ADDIE = Ready, Aim-Aim-Aim-Aim-Aim, FIRE! Oops, the target isn’t what we want to hit any more.
SAM = Ready, FIRE, aim, FIRE Again. You had some initial errors but you hit the target.
Similar to the debate between Waterfall and Agile, rapid content development fits situations where intake is not as controllable or time to market is the highest priority. When there is the ability for deeper analysis or concurrent work, then Addie may be a better fit.
Waterfall methods = ADDIE for training, SDLC for software development
Iterative methods = SAM for training, Agile for software development
