PREDICTING THE EFFECTIVENESS OF A BUSINESS SYSTEM FROM THE POINT OF VIEW OF MANAGING BUSINESS PROCESS EFFICIENCY

V doktorski disertaciji obravnavamo problem obvladovanja poslovnih procesov, kar je v zadnjem desetletju predmet številnih raziskovalnih in znanstvenih člankov, saj marsikateri avtor navaja, da je to ključ do uspešnega poslovanja poslovnega sistema. Ker je obvladovanje poslovnih procesov obsežen in kompleksen problem, smo se v prvem koraku osredotočili zgolj na oblikovanje modela za ugotavljanje povezanosti in moči vpliva dejavnikov širšega in ožjega zunanjega okolja ter notranjih dejavnikov na strukturno učinkovitost izvajanja poslovnih procesov. V drugem koraku raziskave smo oblikovali model za ugotavljanje povezanosti strukturnih kazalnikov učinkovitosti poslovnih procesov z uspešnostjo poslovanja poslovnega sistema oz. neposredne povezanosti dejavnikov širšega in ožjega zunanjega okolja ter notranjih dejavnikov z uspešnostjo poslovanja poslovnega sistema. V teoretičnem delu so predstavljena spoznanja s področja organiziranja poslovnih sistemov, in sicer spreminjanje zahtev in oblik organiziranja poslovnih sistemov v zadnjih dveh desetletjih. Tu poudarjamo prevlado poslovnih procesov, o kateri pišejo številni avtorji, in potrebo po obvladovanju njihovega izvajanja. Spremembe v poslovnem svetu pa zahtevajo tudi spremembe v izvajanju poslovnih procesov, saj se mora njihovo izvajanje prilagoditi številnim dejavnikom, ki vplivajo na učinkovitost izvajanja. Trenutno stanje učinkovitosti izvajanja je mogoče preveriti s številnimi strukturnimi in operativnimi kazalniki učinkovitosti izvajanja poslovnih procesov. Podobno kot na učinkovitost izvajanja poslovnih procesov vpliva veliko zunanjih in notranjih dejavnikov, tudi na uspešnost poslovanja poslovnega sistema poleg učinkovitosti izvajanja poslovnih procesov vpliva še veliko drugih dejavnikov. Različni avtorji ugotavljajo, da je na uspešnost poslovnega sistema treba pogledati širše in ne zgolj s tradicionalnega vidika, pri čemer poudarjajo tudi vlogo in vidik notranjih poslovnih procesov oz. učinkovitost njihovega izvajanja. V raziskavo, predstavljeno v empiričnem delu, smo vključili tri podjetja. V prvi fazi smo ocenili strukturno učinkovitost poslovnih procesov (skupaj 386 procesov), ki so bili zapisani v obliki modelov dogodkovno procesne verige (EPC). Osnovne strukturne kazalnike učinkovitosti smo s faktorsko analizo združili v 7 nepovezanih strukturnih kazalnikov učinkovitosti. Z anketo, izvedeno med vodilnimi zaposlenimi v podjetjih, ki smo jih vključili v raziskavo, smo dobili oceno vpliva posameznih zunanjih in notranjih dejavnikov na učinkovitost izvajanja poslovnih procesov. S korelacijsko in regresijsko analizo smo dokazali povezanost in moč vpliva med posameznimi zunanjimi in/ali notranjimi dejavniki in nepovezanimi strukturnimi kazalniki učinkovitosti izvajanja poslovnih procesov. V drugi fazi smo najprej ocenili uspešnost posameznega podjetja po izbranih kazalnikih uspešnosti poslovanja in nato z opisno statistiko pokazali povezanost med posameznimi nepovezanimi strukturnimi kazalniki učinkovitosti in kazalniki uspešnosti poslovanja.The doctoral dissertation deals with the issue of business process management, which has been widely discussed in numerous research and scientific articles in the last decade, with many authors stating that it is the key to successful business system operations. Since business process management is a wide and complex issue, the first part focuses on forming a model for assessing the connection and power of influence of the outer and inner external environment and the internal factors on structural efficiency of executing business processes. Moving on to the next step, part two, of the research a model for assessing the connection between the structural indicators of business process efficiency and the effectiveness of the business system or the direct connection between the factors from the inner and outer external environment and internal factors and the effectiveness of the business system operation was formed. The theoretical part presents findings in the area of business system organization as well as changes in the demands and forms of organizing business systems in the past two decades. Here the stress is on business process predomination, as stated by numerous authors, and the need for managing their execution. Changes in the business world call for changes in the execution of business processes, having to adapt to numerous factors influencing their efficiency of execution. The current state of their efficiency of execution can be checked by numerous structural and operational indicators of business process execution efficiency. Just like the efficiency of business processes execution is influenced by many internal and external factors, in addition to the efficiency of business process execution the effectiveness of business process operations is influenced by many other factors. Several authors state that the effectiveness of the business system has to be assessed from a point of view largely exceeding the traditional one, with internal business processes or the efficiency of their execution playing an important part. The research presented in the empirical part of the dissertation includes three companies. Phase number one was the assessment of structural efficiency of business processes (altogether 386 processes), presented in the form of event driven process chain (EPC) diagrams. The basic structural indicators of efficiency were joined into 7 unrelated structural indicators of efficiency by using factor analysis. By taking a survey among those in management positions of the companies included in the research, we assessed the influence of individual external and internal factors on the efficiency of business process execution. By using correlation analysis and regression analysis we managed to prove the connection and power of influence between the individual external and/or internal factors and the unrelated structural indicators of business process execution efficiency. Phase number two involved first of all an assessment of the individual company’s effectiveness based on the business effectiveness indicators chosen. This was followed by using descriptive statistics to show the connection between the individual unrelated structural indicators of efficiency and indicators of business effectiveness
