This paper is focused on the process of design and implementation of information systems in small businesses and factors that influence this process. The course of the process per-formed by selected company is first mapped and subsequently analysed by means of case studies of real projects implemented by the company. This analysis points to the frequent occurrence of variances of the projects with the mapped process, especially in the analytical part of the process, and major impact of different psychological and sociological char-acteristics of the client or its representatives on the progress of the project. Based on these findings innovative process changes are suggested. The first change is modification of the analytical process to include acquisition of information on the characteristics of the client and to be more adaptable to the nature and scope of the project. The second is categoriza-tion of the client based on the identified characteristics and assessment of these characteris-tics as potential risks of the project. The last change is the adoption of agile approach to the process, allowing greater process flexibility with respect to the needs of specific clients and higher quality outputs.

This diploma thesis deals with the selection and implementation of information system for a small company. It describes the basic theoretical concepts and problems connected with the area of information systems. The work includes analysis of the current state, determination of the main requirements and parameters of the new information system, assessment of selected variants, selection of a suitable system, implementation, economic evaluation and summary of the expected benefits.

This diploma thesis deals with selection and implementation of information system for company providing IT services. Theoretical background concerning the topic is described in the first part. Then, the company is analyzed and based on the results new information system is suggested. Implementation strategy and risk analysis for implementation of new information system to corporate environment are designed in this thesis. Implementation of the information system is economically evaluated at the end of this thesis.

This thesis informs about currently used technologies, which provide loop protection on data link layer of computer networks. It clarifies issues of Ethernet networks. Chosen protocols are then closely described. There are presented advantages and disadvantages of chosen protocols and they are compared to other technologies. Practical section describes the initial implementation of IS-IS in OMNeT++ environment, which serves as the basic building block of TRILL protocol. An important issue is to verify correctness of implementation.

This master's thesis deals with the analysis of the requirements placed on the technical support information system which should be used in the software developing company. The basic functions of this system are the collecting of information about all kinds of work which the company employees concentrate on and the possibility of statistics generating. Moreover, it is also possible to implement further extensions to the system which will not only enable other functions, that are not related to the primary goal of the system, to be integrated; but also to define new user roles, for which various limited parts of the system will be accessible.
