Abstract: Case Management Model and Notation (CMMN) is a graphical notation used to model less predictable, highly flexible processes that may behave differently in each instance. It uses an event-centred approach and expands on what can be modelled with procedural modelling notations. Nearly a decade since the occurrence of CMMN, its practical use is questionable. We performed this research to identify possible reasons for this and to classify the potential advantages and disadvantages of CMMN. With the aforementioned objectives, we conducted a systematic literature review, which provided a broad insight into the state of the investigated object along with techniques for analysing qualitative data, coding, and successive approximation. From an initial set of 942 articles, 43 remain relevant. The results of the analysis and synthesis of the obtained data from relevant articles were generalised codes, which were used to explicitly answer the research questions. The results indicate that CMMN has good foundations in the declarative modelling approach and within the Case Management paradigm. Nevertheless, some issues were identified with the notation and elements of CMMN and with its complement—Business Process Model and Notation (BPMN).

Abstract: V diplomski nalogi smo v teoretičnem delu opisali osnove poslovnih procesov in natančneje predstavili faze upravljanja le-teh. Temu je sledil praktični del diplomske naloge, katerega cilj je bil digitalizirati zastarel proces v izbranem podjetju. Po analizi obstoječega procesa smo s pomočjo BPMN notacije izdelali diagram izvedbe prenovljenega procesa. Proces smo nato implementirali in opisali, katere tehnologije smo uporabili za izdelavo. Na koncu smo našo novo spletno aplikacijo tudi testirali na končnih uporabnikih in našo rešitev analizirali z oceno uporabnosti sistema - SUS (System Usability Scale) analizo.

Abstract: Izdelava modelov procesov in njihova primerjava z obstoječim in željenim stanjem postajajo vse bolj uporabni, še posebno takrat, ko podjetje prenavlja informacijski sistem, na katerem upravlja večino opravil, ki se izvaja v njem. V postopku prenove informacijskega sistema je trenutno podjetje Helios TBLUS d.o.o., ki želi vedeti, če so procesi, ki jih izvajajo, primerljivi s SAP-ovo najboljšo prakso. Za prikaz in primerjanje procesov se je podjetje odločilo za uporabo programske rešitve za modeliranje procesov SAP Signavio Process Manager. Za izvajanje analize procesov smo se odločili za proces iz planiranja proizvodnje, in sicer iz primera naročila na zalogo, saj je teh primerov znotraj podjetja največ. Simulacija in analiza procesa sta pokazali, da je trenutno stanje dovolj dobro, da se ga uvede v novo okolje.

Abstract: V diplomski nalogi smo v teoretičnem delu poudarili, kaj je pomen in namen digitalizacije poslovnih procesov, predstavili korake digitalizacije poslovnega procesa ter opisali grafično notacijo BPMN (Business Process Model And Notation) za modeliranje poslovnih procesov. Pri izdelavi naloge smo si zastavili cilj, da bi z digitalizacijo poslovnega procesa naročilo in nakup prevoza podjetju Avtoprevozništvo Topler omogočili, da bi postalo konkurenčno ostalim sorodnim podjetjem na trgu. Na osnovi analize poslovnega procesa in izdelanih modelih poslovnega procesa (AS – IS in TO – BE) s pomočjo notacije BPMN v orodju Signavio smo razvili spletno rešitev za uporabnike, ki želijo naročiti prevoz. Rešitev ponuja različne možnosti uporabe neregistriranim uporabnikom – gostom in registriranim uporabnikom, kateri lahko na enem mestu opravijo vse korake, od povpraševanja za prevoz do nakupa prevoza. Hkrati pa spletna rešitev podjetju ponuja lažji način za pregled rezervacije prevozov. Po izdelavi končne rešitve smo s končnimi uporabniki preverili še uporabnost rešitve.

Abstract: The main purpose of business process diagrams is to facilitate the communication between the process-related stakeholders, which directly affects the decision-making. For this reason, they must be easy to understand. However, this is often challenging to achieve, since business process diagrams can become large and complex. This, in turn, can negatively affect their correctness and understandability. The goal of this doctoral thesis was to propose and investigate an approach that makes business process diagrams appear less complex, without changing the corresponding diagrammatic notation or the business process diagrams themselves. This was done by manipulating the opacity of graphical elements in order to emphasize the important parts of a business process diagram by lowlighting the irrelevant ones. The proposed solution, named Emphasis, implemented with opacity-based Graphical Highlight pattern, abbreviated as simply Graphical highlights, was subsequently applied to sample business process diagram, modeled in Business Process Model and Notation (BPMN). The analysis demonstrated that the structural complexity of the business process diagrams decreased when the proposed solution was applied. Afterwards, a Web application prototype was implemented, which supports the proposed set of Graphical highlights. Furthermore, we empirically validated whether Graphical highlights positively impact cognitive effectiveness of business process diagrams, and if the users will find the prototype implementation useful. To this end, an experimental research, which included 85 participants, was conducted. The participants were randomly assigned in either the treatment group (Graphical highlights diagram representation approach), or the control group (conventional diagram representation approach). In accordance with the definition of cognitive effectiveness, speed, ease, and accuracy of answering 26 comprehension questions were observed, along with the perceived usefulness of the prototype. The results of the analysis demonstrated that participants who used Graphical highlights significantly outperformed those that used the conventional approach in all experiment's observations. We can conclude that using Graphical highlights increases the cognitive effectiveness of business process diagrams, while the corresponding prototype implementation is perceived as being useful.
