How are you going to recover from the critical material delay caused by a supplier in the last stage of the project?

Replace it with an alternative approved material supplier

First: The delay cannot be a surprise, so you have to have alternatives ready, preferably with the supplier who has the problem

Make a recover schedule and Find out the actual balance qty to be executed Find the current productivity for the activity Now either u can increase the productivity to achieve the results in time Or recalculate using multiple shifts for the work or use more resources for the particular activity to finish within deadlines.

That´s why you draw supply contracts with penalties if contract is broken.

The question is what kind of project manager are you? The kind that thinks that projects are wonderful and you won't need to pull the plug, the kind that thinks everything will be fine and contingencies won't happen? Or alternatively the kind that oversees breaking points in the future... 

 

Now what? Recover plans? Reschedule? Replan? You had that responsability months ago.

It is always prudent to prevent such stock out situations for  critical parts. For such parts, we practice two bin system, one lot being sent to us and a partial quantiy kept in Supplier's inventory. This gives us an opportunity to prevent stock out situation. We do this with the suppliers, where unexpected delays happened by experience.
