While it is true that you have good designs that are well-accepted by your market and that all you need to do is to replicate them in the exact same way as the prototype, you need to maintain quality control over all the batches of production.
Production conditions vary because of so many factors. And these factors are dependent on the weather, climactic changes, workers, materials and the like. But your consumers or market do not know that. Or even if they know, they don’t care because all they want is the highest quality of products that they are paying for or willing to pay for. So you need to maintain your quality or risk wasting an entire batch of production because of returns and refunds from your customers.
If you have a big mechanized production, then you will need rigid quality control and also quality management software. This will allow you to keep track of all the production processes and outputs. If there is a problem, you will know where to check and to correct in order to meet up with your standards of production or the standards of the government regulating body covering your business.
Quality management software will greatly improve efficiency in the manufacturing area and eventually boost your sales and revenue because your clients will know that your products are always reliable.
