Centralized management of user access rights in large organizations with heterogeneous structure
Balada, Jakub ; Vohnoutová, Marta (advisor) ; Beneš, Antonín (referee)
Each platform, a database, a group of applications etc. have its own management, its own user list and list of user rights, its own security policy and so on. The administration is demanding, application control and data access make demands both on system administrators, data owners, and common users. This situation is not suitable even for a general security policy of an organization. That is why the Identity and Access Management is implemented. The Identity Management solves a central user management including their user roles. User accounts as well as other user information in subordinate systems and applications are created, modified and deleted exclusively through the Identity Management. On the other hand, the Access Management is the single source of information about user access rights for systems and applications. This diploma thesis describes in detail a system of hierarchy of user access rights, a way, particular user access rights are approved, and a way of their activations. The solution described, is a part of a real large project made for a big state authority.

Agile methodologies in complex environment
Balada, Jakub ; Buchalcevová, Alena (advisor) ; Pitner, Tomáš (referee) ; Antlová, Klára (referee)
Only a small number of projects of information system development succeed. Agile methodologies have contributed to a higher level of success of specific projects developed by small teams. Nevertheless, most IT companies still refuse this approach with large-scale projects. This paper comments on the conditions that must be fulfilled for agile adoption, analyzes the limitation of such processes, and describes the approaches for the solutions of such problems with the focus on projects in a complex environment. By means of a case study, the next part of the paper shows the advantages of adopting an agile approach in a real project in a complex environment, which is in conflict with the so far presented limitations of this methodology. The project was evaluated as a success, primary, due to the implementation of the agile methodology during the development phase. This implementation helped meet all the project deadlines, accelerate bug-fixing, and especially deliver functionalities which brought an additional value to the customer. Based on the findings of the case study, the procedures and practices extending the chosen agile methodology are defined. Such procedures and practices can be used in other projects in complex environments in the future. Thus, the paper shows more options for the use of these methodologies, which may help its wider use in the future and hence increasing the success of projects focused on the development of information systems. Such situation would lead to an effective interconnectedness of ICT and business strategies, especially due to the flexible delivery of currently needed ICT services.

Scaling of agile methodologies
Zikmund, Jan ; Buchalcevová, Alena (advisor) ; Balada, Jakub (referee)
Agile methodologies have become a routine part of software development. Despite their initial focus on small and local teams working on relatively simple applications, the current trend is their application to development of large and complex systems. This work provides a general introduction to agile methodologies, including the extent of their use in practice, limitations of these methods together with the introduction of the concept of scaling. The work is then devoted to starting points and the general approaches to scaling. In conclu-sion, the practical part of the work proposes methodology for evaluating performance of agile methodologies in projects. The aim is to provide an overview of agile methodologies and subsequently particularly analyze soft, organizational problems that are related to scaling agile methodologies. This work can serve as tool for management, or project office when considering adoption of agile methods.
