A customer-oriented and fast response as well as an above-average service level in the support and operation of client-server systems is becoming increasingly important as an important competitive factor for IT system houses. Particularly in times of increasing competitive intensity and the need for uninterrupted operation of the IT infrastructure, the demand for reliable and optimally configured systems is continuously rising. Since the company has grown primarily through referrals to date, significant increases can be expected in the coming years, for example, through the establishment of a sales force. Here it should be pointed out in particular that there is a high scaling potential in one of the customer segments, which has so far only been partially exploited.
