Quality of service & process control: What is their efficiency in available IT products?

The paper presents and discusses the quality of service and process control in selected information technology (IT) products with links to their efficiency. The advantage is a wider analysis this problem over operating and database systems, Business Intelligence (BI) and Customer Relationship Management (CRM) products with respect to the complexity of the implementation. A good starting point is an analysis of selected products based on Petri Nets with support simulation and further analysis. Th is analysis produces re sults in order to find a way of improving adopted services for web applications. The Jaspersoft Suite (BI) and Sugar CRM products offer minimal information and methods to control processes via a scheduler for reports and meetings. Effective control of processes needs an elaborate solution. An inspirational way is complex solution in the Oracle database system with chains for a better overview about process relations and contexts. Difficult orientation within the Oracle website is compensated by a user-friendly interface that is absent in the OpenSolaris operating system with otherwise comprehensive environment for process control.
