Abstract

Evaluating the economics of information systems is a difficult task. In addition to classical approaches to the economic evaluation of information systems, attention is paid to individual processes and workflows. The quality of information systems functionality is based on a quality workflow processes. A poorly designed workflow of the information system leads to a number of errors and problems in exchanging information within the system. The lower the error rate and the higher the efficiency of individual activities, the higher the economic value of the information system and, as the case may be, of other analytical, expert or decision systems in the organisation. In this paper, known principles of cohesion and coupling are used. The selected real process is evaluated within the framework of the agricultural information system operated by the Ministry of Agriculture of the Czech Republic. In the article is created a design the structure of information elements of the modelled workflow, measured cohesion and coupling and compared with two alternatives.

Keywords

Workflow process, information systems, cohesion, evaluating process, agriculture.
