At this point in the course, we have seen some recurring relationships between resource flexibility, and how it impacts the resource utilization vs. queue time or lead time trade-off. Consider the two project scheduling scenarios we examined in Lesson 14 Commentary 2. One scenario assumed resources were totally flexible, and could be made available to the project at a moment's notice. The other assumed resources were inflexible, and as such each activity needed its own scheduled start time so we could schedule the resources accordingly.

Do you see parallels between these two scenarios, and the push vs. pull discussion from Lesson 13? Which of the two project scheduling scenarios involved a "lead time stack up" similar to what we get with MRP? Try to identify as many similarities between the MRP vs. kanban discussions we had earlier, and the two project scheduling scenarios we examined in this lesson.
