Business process modelling and analysing is undoubtedly one of the most important parts of Applied (Business) Informatics. Quality of business process models (diagrams) is crucial for any purpose in this area. The goal of a process analyst’s work is to create generally understandable, explicit and error free models. If a process is properly described, created models can be used as an input into deep analysis and optimization. It can be assumed that properly designed business process models (similarly as in the case of correctly written algorithms) contain characteristics that can be mathematically described. Besides it will be possible to create a tool that will help process analysts to design proper models. As part of this review will be conducted systematic literature review in order to find and analyse business process model’s design and business process model’s quality measures. It was found that mentioned area had already been the subject of research investigation in the past. Thirty-three suitable scientific publications and twenty-two quality measures were found. Analysed scientific publications and existing quality measures do not reflect all important attributes of business process model’s clarity, simplicity and completeness. Therefore it would be appropriate to add new measures of quality.

This article deals with the problem of critical employees’ oversight. In the article is proposed set of processes which can with cooperation with Data Mining and Ambient Intelligence, in some cases, predict behaviour and movement of monitored objects/people based on reasoned context from set of different sources. The difference between prediction and observed reality can be evaluated and based on rules and gathered information about context can be taken action to prevent security breach and damages to the company. At the end a case scenario is presented which demonstrate behaviour of the system and possible options how the system can prevent damages to assets.

One of the many often frequented topics as normal journalism, so the professional public, is the problem of traffic accidents. This article illustrates the orientation of considerations to a less known context of accidents, with the help of constructive systems theory and its methods, cluster analysis and geoinformation engineering. Traffic accident is reframing the space-time, and therefore it can be to study with tools of technology of geographic information systems. The application of system approach enabling the formulation of the system model, grabbed by tools of geoinformation engineering and multicriterial and cluster analysis.

This paper is focused on the testing and evaluating of public administration electronic forms from the usability point of view. Its objective is to design a suitable methodology for usability testing of electronic forms and their description and distribution to public administration information systems professionals. Firstly, methods of usability engineering are summarized and a suitable method for usability testing and evaluation of electronic forms is selected. Farther, the methodology of electronic forms usability testing that uses the selected method is suggested. In the last part of the paper the case study that uses the proposed methodology is suggested and performed. The main benefit of the work is the design of testing methodology and proposition of the set of recommendations for new public administration electronic forms design.
