There is one and only one question that needs to be asked when ever any speaks about a pr oject management approach. Whether this approach is full DoD IMP/IMS down to someone claiming to have "magic beans." The method must ask and answer...
- How long are you willing to wait to find out you're late, over budget, or not on technical specification?
- What are you going to do to get back to some place that is acceptable to all the participants?
If your magic beans or your DoD FAR 15.2 procurement process can't answer these questions in some unit of measurable meaningful to the all the participants - you're not doing project management.
