Great memory Kyna!
Yes we are using Workfront to keep track of shipping/tracking information. When we first started it was a custom form and the in-house printer would fill in the fields. We have reports that easily pull "Tracking Number" so our stakeholders can quickly see the information without opening the project.
Since then we have upgraded to our Fusion implementation that is pulling the information directly from the printer software into Workfront so no one has to copy/paste by hand. We also have an automated message that tags the project owner and sponsor on the task and lets them know their (project type) has shipped on (date) and here is the tracking numbers ____.
Hope that helps!
