How to make a sandwich
summary
Argues the sandwich model is misunderstood and usually doesn’t work, frames feedback as a systems problem using Systems Theory and timing to show small frequent inputs beat annual reviews, gives three concrete models—porpoise feedback, sandwich, and Acts feedback—and prescribes the actionable SBI formula (Situation Behavior Impact) plus a pragmatic rule of 63 (see 63 things wrong pick 3) so feedback is specific, timebound, and owned and so the loop actually changes behaviour.
