It will be too redundant to say that getting the product designs right the first time is the top most priority for manufacturers. Businesses that have not recognized and adapted the right technologies have already been outpaced by early-adopters and survived the competition successfully. The reason why technologies have helped so much is because they enable businesses to bring down the cost and time on design rework and preventable engineering mistakes. It is estimated that 30-50% of time is spent on design rework and fixing errors and almost 24% of these errors are related to manufacturability.

The prime reason why these errors occur is due to ignoring the gap between exact and real world scenarios. This can be best understood considering the example of sheet metal products. These products are made up from metal blanks or stocks that are formed to required shapes using press. There are numerous design parameters like tolerances, hole spacing, hole dia., bend allowances, etc. to be taken care of. With virtual CAD tools, designing sheet metal components is fairly easy and look good on screen, but it is equally important to ensure the manufacturability of these components.
