Don't be afraid of the costs.
Individual, customised products do not need to be more expensive than serial productions - if you compare the costs of a whole system, the opposite is often the case. Solutions that are adapted to the customer's requirements lower development and production costs. The most modern production and test strategies lower production costs. High efficiencies result in cost savings - also in service. A long service life, permanent product improvements and service and low field failure rates secure the availability of your systems, minimise maintenance costs and ensure customer loyalty and satisfaction.
