The Mazurek company has long suffered from a problem with high complexity and errors in the technical preparation of the production of custom-made gates and fencing. With the help of external specialists, a functional prototype of a web configurator, filled with the most common constructions, and its connection with ERP Premier and 3D Solid Works was implemented in the company. The technical preparation of production is thus largely generated automatically based on customer requirements, which are interpreted into the system through the web configurator. This minimized errors caused by manually rewriting data from one system to another. Thanks to the introduction of this innovation, the company calculated the expected increase in sales and profit by 20%. The company was able to expand its offer with new components and reduced the error rate of TPV and the time required to process the order.
