Large Information Technology service support system is planned to be deployed at Siemens IT Solutions and Services world wide. The heart of the system is a business process execution platform which organizes distributed services by means of business process modeling notation. This paper addresses performance aspects of this system: how components distribution affects system response time. Results demonstrate application of performance modeling and simulation approaches on early design stages with lack of initial data.
