An example of this happening is when the manufacturer sells the business faulty goods.When the business notices a fault they will think that there are more of the faulty goods and have to waste their own time to check for more faulty products.
All of this can lead bigger problems like having to switch to a different manufacturer or fining the current manufacturer because of the faulty goods being there in the first place.
When the faulty products go to the customers unnoticed the problem can escalate when customers are lost and sales go down.
The largest problem of them all is when sales for both the business and manufacturer are lost and the consumers still don't get what they want.This can lead to the manufacturer losing one of their good customers.
Lots of money,trust,time and confidence would be lost in this kind of situation because of one small fault.
