The rapid technical progress in the development of mobile devices and technologies offers new possibilities for improving and streamlining the performance of business processes. However, only few successful mobile applications exist in the business area. This paper discusses the benefits an enterprise can gain by using mobile technologies in business processes. It presents general indicators to measure the performance of business processes and shows how these indicators must be adapted to be useful to determine the benefit of mobile applications. Then, the set of indicators is applied in a real-world scenario. The results show that indicators like throughput time, error rate, reduction of redundancy, and increased flexibility are important for the benefit of mobile technologies
