Link Procurement Tasks to deliver Just-In-Time without using up slack?
Dale,
Thank you for the response. The Start to Finish seems to be the cleanest, quickest way to show "order by" dates in the schedule. The drawback seems to be that, if a material delivery is delayed, this won't show the impact to subsequent tasks, correct? For example, if you are halfway thru a 6-week material lead time, you should be receiving material in 3 weeks. But you find out you won't get the material for 4 weeks (one week later than scheduled) how do you show this delay in your schedule? With Start to Finish relationship type, the schedule will say the subsequent task can Start before Material Delivery is finished.
Thank you

Good question. In a situation like this, I would first increase the Duration of the Order Material task by one week, and then I would apply a SNET constraint on the Material Delivery task that shows the new delivery date.
When you set the initial Start to Finish task dependency, you could manage the risk for the possibility of the order taking longer by adding Lead time (Negative lag) to the dependency, such as by adding 1 week of Lead time. I realize this is not a perfect solution, then I hope this helps.
