Summary: On one hand, business processes of every economic subject are continuously exposed to negative effects of cyclical aging and on the other hand, they are under the influence of the changes in the environment. Suppression of these negative effects on business processes is in the easiest way done by reengineering, which is the specific form of business process directed to effective adjustment of these processes with the demands of external and internal changes. This refers to all economic conditions – both stable and in crisis.
In this context, it should be emphasized that the current theory of the engineering of business processes is mainly based on subjective and static approach, and it is predominantly adapted to stable general business conditions. This approach, since its long and successful usage, could be called traditional. In contrary to this, general business conditions in crisis, followed by changes in economic, social and political environment, which are difficult to predict, demand the traditional reengineering to be abandoned as inefficient. Because of that, this approach should be replaced with exploratory reengineering, since it is significantly objective and appropriate for the unstable business conditions.
So far, the exploratory way of reengineering has not been theoretically precisely defined and elaborated since it is still in the phase of construction and time is needed to define its basic factors and characteristics precisely. Because of that, in this manuscript we try to deepen theory and practice of exploratory directed reengineering of the business processes of economic subjects that work in the general crisis conditions. In this manuscript, we particularly emphasize the processing of two-phased procedure of exploratory reengineering in the process of projecting and making changes, in accordance with the changed demands of the environment. The goal of the example analyzed in this manuscript was to determine the effectiveness of this exploratory approach, i.e. to find out if the benefits of the established reengineering were higher than the expenses of its initiation.
Key words: business processes, changes, reengineering, effectiveness.
