Every new product begins with an idea. This idea usually stems from internal (further) developments or wishes expressed by customers. All ideas are evaluated by various business criteria. If the project is given the green light, first product specimens are made in close coordination with customers to test practical feasibility. The factors of user-friendliness and safety already play a decisive role in this early phase. Regulatory conditions and classifications are also taken into consideration. Based on the likely safety class of the product later on, exactly defined internal procedures come into effect for the further steps.
