The process of choosing and integrating a network management system (NMS) to an existing computer network became a big question due to the complexity of used technologies and the variety of NMS options.Most of computer networks are being developed according to their internal rules in cloud environments.The use of NMS requires not only infrastructural changes, consequently increasing the cost of integration and maintenance, but also increases the risk of potential failures.In this paper, conception and method of express choice to implement and integrate a network management system are presented.Review of basic methods of cost analysis for IT systems is presented.The simplified conception of cost benefits analysis (CBA) is utilized as a basis of the offered method.A final estimation is based on three groups of parameters: parameters of expected integration risk evaluation, expected effect and level of completed management tasks.The explanation of the method is provided via example.
