Verification ensures that the the customer specifications are meant. Without verifying specifications, you are blindly trusting what the manufacturing department took to be what was meant on the DID. In industry, this is a dangerous assumption because the departments rarely if ever understand each other fully. If a product is not verified, the customer can come back to the company and refuse to pay for the product because it is not what they asked for. Now the company has lost the resources, time, and money that the product took to make. In addition, the customer will most likely not deal with the company again and spread a negative reputation. Verification of inputs is needed as a safeguard against waste. Not verifying data leads to wasted opportunity, money, and future opportunities.
