This diploma thesis is focused on optimizing administration management in the Czech telecommunication office. The thesis has three essential objectives. The first objective is the analysis of present state of the administration management using the process modelling. The second objective is to identify the real potential for improvements of the process group. That means to specify process priority, estimate current and desired levels of process maturity, identify key activities and determine the level of process description and processing framing tables. These activities are supported by the methodically theoretical text at the first part of the thesis. The evaluation of limits determining potential improvements resulted from previous chapters and is contained in the final part of this thesis. The fundamental objective of this work is to design the optimization of the process group using the form of future projects.
