The first part discusses the development models in terms of testing segment and the following section focuses specifically on the methodology of agile testing and development as a whole, including applicable metrics for evaluating various aspects of software exiting the testing phase. The third major section lets the reader get acquainted with the Siemens organization and methods of their software testing and by analyzing real-world project it assesses the strengths and weaknesses of the particular testing process and its management. The practical part of this thesis lies in the design and implementation of a plug-in for the JIRA environment. This tool is able to identify and quantify the long term status of the project phases of agile development and testing in a clear and interactive way, while the outputs are represented by clearly defined problems that can be more easily treated, as one can argue further progress.
