The author pointed says that no model (old or new) will prevent ‘boring, lifeless training.’ Can the [classic] ADDIE model be enhanced? Absolutely.
The essential differences in these models, including what’s captured in Allen’s SAM process, is to make the model less linear and to include feedback loops within the process for regular look backs, particularly to the data from the analysis phase.
The problem with these models, including SAM, is that they seem to require redundancy. There are certainly instances when such redundancy is not necessary.
... the ADDIE model was [not] designed to be a strictly linear process anyway...
[The author] ...prefers this cyclic visualization of ADDIE to better show the interactions between the phases.
From the comments: " Is SAM similar to Agile and ADDIE similar to Waterfall, as in software development?
