The close interaction between customer, supplier and distributor already in the pre-development phase of a product leads to fast development times, an optimization of the time-to-market factor, high quality and ultimately to the best product for the customer. Together with the Italian distributor GSR Technology, the complete central operating unit including display with capacitive touch and cover glass as well as the control unit was developed for a well-known Italian manufacturer of coffee machines. The challenges were the special design of the display, which was done in close cooperation with GSR and the customer. The customer expressly welcomed the close interaction between the manufacturer, the distributor as integrator and technical consultant and his own development department in order to achieve the best possible result, especially during the design phase, in uncomplicated contact with fast response times. Holitech can draw on its experience from many projects and contribute to the success of the project.
