When using the Theory of Constraints approach to scheduling (Drum-Buffer-Rope), why do we say "foreschedule into a bottleneck, backschedule away from the bottleneck"? Group of answer choices A: We use backscheduling away from the bottleneck so things get to the end of the process as-late-as-possible thus creating a time (slack) gap between the bottleneck and the end of the process B: We use forescheduling into the bottleneck so things get to the bottleneck as soon as possible C: We never want to "block" the exit of material from a bottleneck D: We want to buffer material in front of the bottleneck E: All of the above
