Aftercare Operations by Simone Hoferer

The lecture Aftercare Operations by Simone Hoferer is from the course Risk Management: After Project Completion. It contains the following chapters:

How can it happen, that a project needs to be continued and to be worked on even after the handover and the final invoice?

After returning home from a project, there are still many open tasks. What tasks among others do you have to complete?

You need to work off the list of defects and shortcomings while agreeing upon appropriate solutions with your customers.
You need to initiate repair/replacement product and delivery.
All open issues with the customers or suppliers need to be clarified.
If agreed upon initiate additional consignment.
You need to organize the second part of the project by going through the parts with your colleagues.

Why can it happen that, in a warranty claim or defect caused by the supplier, the supplier cannot be called?

Because there are two different and separate contracts. So it may not be possible to hand over the claims of the customer to the supplier due to the individual contract.
Because the documentation of the defects and shortcomings of the supplier are not correct or the timeline to inform the supplier was not met.
Because maybe one can prove that it was the suppliers fault that caused the shortcomings/ defect.
Because one does not want the customer to get to know the supplier.
