Assessing the conditions of productivity of individual workers who process information and use IT has been a concern for many researchers. Prior studies have applied different theoretical foundations to study the relationship between IT use and productivity at individual level in post adoption scenarios and have provided mixed results. In the last decades, the proposition that there is a need for a set of factors to be changed in a synchronized fashion when using an IT system has received particular attention. Very little, however, is known about the configurations of these factors at individual level. To investigate this gap, we have designed a new research model of an information worker’s individual productivity when a more aligned IT system is used in a synchronized manner with both individual and organizational factors. The formulated research model is grounded on the complementarity theory, functioning here as a meta-theory guiding the linking of productivity theory, Kirton’s adaption-innovation theory, and several theoretical bodies on the structure of production processes and human resource management. The formulated model was tested in two empirical studies – a longitudinal quasi-randomized field experiment and an online experiment – conducted to investigate configurations of complementary factors that increase productivity when a new, more aligned IT system is used. Overall, the two studies shed important light on configurations of complementary factors and the improvement of the research design to study their impact on IT-enabled productivity. The obtained results contribute to the research that focuses on individual information worker IT-enabled productivity as well as research that rests on the complementarity theory with new configurations of complementary factors that, when matched correctly, can increase individual productivity of information workers. Eventually, the studies presented here advocate that further research is needed to increase our in-depth understanding of complementary factors and their impact on individual IT-enabled productivity of information workers.

As a result of the rapid development of technology and the implementation of it in work environments, productivity and profit can increase for an organization. Email has led to much shorter ways of communication but there are also less positive aspects of technology. Technostress, information overload and email overload are all three effects of this new ubiquitous digital era. We ask how individual information workers manage and reply to incoming email, to extend our knowledge regarding the effects of email overload on information workers, and to identify their coping strategies in their work life context. This knowledge can be used by practitioners, designers and researchers to develop email as a service further. By conducting nine qualitative interviews with information workers employed in three different organization, we found that balance in email management is important to utilize the full potential of the service, and it would be useful for individuals, as well as organizations, to establish clear rules regarding email use both within work hours, as well as on leisure time.

This diploma thesis deals with issue of optimization of information needs in engineering company Weiler s.r.o. This work consists of otheoretical background, on which is established practical part, which contains strategic analysis of companies environment and information needs. There is processed strategic plan of optimization in three alternatives on these foundations - pessimistic with no change in the company, realistic, which counts with use of one information worker and optimistic, which counts with establishing an information department in the company. The final plan is elaboration of realistic alternative including financial plan, which contains the electivity calculation.

The aim of the diploma thesis is to describe the basic characteristics and basic analysis of the information profession of the Czech Republic in the sphere of state administration and state- controlled information institutions. Some space of the work is devoted to the characteristics of public and state administration. The diploma thesis emphasizes the institutions of state administration and their division. The following chapter deals with information institutions and information folders in the state administration and their categorization. The core of the thesis is the definition of the concept of an information specialist. The final chapter summarizes not only the overview of the information science study in the Czech Republic but also the analysis of the professional application of Information Studies and Librarianship graduates in the state administration institutions.
