Vol. 9, nr 2

Companies operating as multi-site organizations usually operate disparate business processes across sites and IT systems written in various technologies. Therefore, unification of business processes as well as IT systems and technologies are becoming matters of high significance. The purpose of the paper is to present a method for unifying business processes of a multi-site company. The method addresses also the matter of IT support to selected activities within business processes. The method, proposed in the paper, examines the similarity of processes and is based on a comparison of pairs of nodes on the label and type. During unification, two version of the same process are compared. To the new, unified version, only the most time-efficient activities are selected. Corresponding, less effective activities are omitted. The method assumes refinement of business processes which stems from ability to execute business process in a different manner thanks to support of IT systems. An example of a business process unification in the medical sector with the participation of the Polish National Health Fund (NHF) was enclosed. In the paper are presented: AS-IS state, method of unification and TO-BE state of medical prescription lifecycle. In that example, selected similarity metrics of business processes are used. Furthermore, formulae are proposed for calculating savings that can be gained through unification of business processes in a multi-site company. A specific example of such calculations is presented. The reduction of time needed to carry out business process activities is realistic and can become a source of financial savings for a multi-site company. The medical example shows ability to reduce process execution time from hours to minutes. Such a significant time gain is possible not only owing to unification of the business process activities, but mainly through IT suport and automation of most of the process activities.
