COST
No matter where the fault is identified on the production line, the identification in itself will save a multitude of costs, from the production expense, to marketing and sales.
The earlier the fault is detected the less cost incurred.
TIME
If a fault is not discovered and left to the latter stages of the production line, the knock on effect on product launch is further elongated. Product launches are timed for heightened demand, missing the buying period and delaying the cycle would severely hamper production and sales.
REPUTATION
Product recall is not only expensive it can also have a detrimental effect on your products reputation.
Faulty products bing exposed by consumers severely effects he perception of the brand and future customer loyalty.
