One of the project I worked on at my company, we had to include anchoring brackets with a new server rack that we built up to show to our customer for their opinion and approval. We got a shipment from our vendor for the brackets, however upon inspection we discovered that the clearance slots in the brackets were not long enough and didn’t line up with the mounting holes in the rack. We had to get this new prototype to the customer that week, no excuses. Because of the lead time from our vendor we couldn’t order another batch of brackets in time, so we took the brackets and reworked them using whatever tools we could find to not have this shipment delayed. Not the easiest option but our backs were against the wall to get this prototype shipped that week. We did communicate the issue with the vendor so that the next shipment was made correctly.
