Improvement of Spreadsheet Quality through Reduction of End-User Overconfidence: Case Study

This paper is prompted by and based on earlier research into developers' overconfidence as one of the main causes of spreadsheet errors. Similar to related research, the aim of the paper was to ascertain the existence of overconfidence, and then examine the possibility of its reduction by means of experimental treatment designed for the needs of the research. A quasi-experiment was conducted to this end, in which 62 students of the Faculty of Economics of the University of Novi Sad participated, divided into the experimental and control group. Participants of both groups developed domain free spreadsheets in two iterations each. After the first iterations, students in the experimental group were subjected to experimental treatment: they attended lectures on spreadsheet errors taxonomies supported by real-life examples, and about spreadsheet best practices in the area of spreadsheet error prevention. Results showed that spreadsheet developers who were informed about spreadsheet error taxonomies and spreadsheet best practices create more accurate spreadsheets and are less self-confident in terms of accuracy of their spreadsheets

An Empirical Investigation of Software Testing Methods and Techniques in the Province of Vojvodina

A high-quality test design is a conditio sine qua non of successful software testing process, and its effectiveness depends, among other things, on the choice and proper use of appropriate methods and relevant software testing techniques. The main goal of this study was to provide insight into the use of current methods and relevant software testing techniques used in the test design phase of software testing process in software companies in the Province of Vojvodina. The empirical study was conducted by a survey research strategy in twenty-four software organisations. Eighty-three respondents took part in the survey. Descriptive analysis, correlation analysis, hierarchical cluster analysis, the multidimensional scaling, binomial test and Cohran\u27s Q test were used for analyzing gathered quantitative data. The survey results have shown that respondents use to a significant extent the techniques belonging to ISO/IEC/IEEE 29119 testing standard. Comparison of the gathered data with individual results of similar studies conducted in Canada, Australia and Turkey has shown similarities between them and companies in the Province of Vojvodina. The findings of this study present empirically verified recommendations for testing design phase realization in the form of least and most used software testing methods and techniques, their benefits, limitations and details in application, similarities between software testing techniques, software testing techniques clusters and the probability of use of individual techniques

Kanali distribucije u savremenom bankarstvu

U savremenim uslovima neizvesnog i izuzetno konkurentnog okruženja banke su izložene velikom pritisku unapređenja kvaliteta usluga, uz istovremeno smanjenje troškova poslovanja. U uslovima u kojima cenovna konkurentnosti ne obezbeđuje dovoljan prostor za tržišno pozicioniranje, banke su suočene sa imperativnom poboljšanja korisničkog servisa. Navedena tendencija je posebno izraženo za retail bankarski segment, pri čemu kanali distribucije igraju ključnu ulogu u pružanju kvalitetnijeg korisničkog iskustva, jer interakcije sa klijentima počinju i završavaju u okviru kanala distribucije. Korisnici bankarskih usluga očekuju sve veću udobnost, dostupnost, personalizaciju i pouzdanost kanala bankarskih distributivnih mreža. Da bi ostvarile postavljene zahteve korisnika banke se u velikoj meri oslanjaju na mogućnosti i novitete informaciono-komunikacione tehnologije. Aktuelnost predložene teme predstavljala osnovnu motivaciju autorima ove monografije posvećene analizi razvoja i trendova u oblasti elektronskog bankarstva, kanala distribucije i elektronskih transakcija. Autori priloga predstavili su rezultate analize pojedinih tema koji dominantno targetiraju segment kanala u savremenom bankarstvu. Osvrt na istorijski razvoj elektronskog bankarstva, sa akcentom na uticaj i prilagođavanje bankarskog poslovanja inovacijama koje je donosio revolucionarni razvoj informaciono-komunikacione tehnologije. Posebna dimenzija prvog poglavlja predstavlja i analizu najnovijih trendova u Srbiji. U okviru drugog poglavlja detaljno su opisani rizici sa kojima se banke suočavaju u domenu elektronskog bankarstva, a pored pregleda situacije u Srbiji, dat je pregled i za Bosnu i Hercegovinu, Crnu Goru i Hrvatsku. Treće poglavlje je posvećeno izazovima kojima se banke suočavaju u retail sektoru kada su u pitanju elektronski kanali distribucije. Predstavljeni su rezultati analize trendova koji utiču na promene u bankarskim kanalima distribucije. Poglavlje obuhvata i kriterijume za izbor optimalne strategije kanala distribucije. Veoma važna tema, razvoj i trendovi u oblasti platnih kartica vrlo detaljno je predstavljena u četvrtom poglavlju. Centralni deo monografije, peto poglavlje, posvećeno je vrlo aktuelnoj temi – mogućnostima primene društvenih mreža u bankarstvu. Poglavlje obrađuje fenomen Interneta i Web 2.0 tehnologije i servisa bazirane na njoj. Tema je obrađena kroz dve perspektive: korisnika bankarskih usluga i banaka. Logičan nastavak ove teme su inovacije u mobilnom bankarstvu, obrađenu u šestom poglavlju. Rast potreba korisnika za lagodnijim i lakšim upravljanjem bankovnim računima i drugim bankarskim uslugama morali su zadovoljiti i proizvođači mobilnih telefona, a to se pre svega odnosi na razvoj aplikacija kao što su Google Walet i Apple Pay. Poslednja, treća glava monografije obuhvata temu elektronskih transakcija. Sedmo poglavlje obrađuje vrlo važnu i kompleksnu oblast – razmenu poslovnih transakcija. Obuhvaćena je analiza rada klirinških kuća, kao i rešenja za elektronska plaćanja poput MultiChain, Blue Mix i Bitcoin. Osmo poglavlje doprinosi kvalitetu monografije prikazom rezultata analize navika koje građani Srbije imaju u onlajn transakcijama u poređenju sa građanima razvijenih zemalja Evropske unije

SPREMNOST NA USVAJANJE I PRIMJENU TEHNOLOGIJA WEB 2.0 U SREDNJEM OBRAZOVANJU – SLUČAJ VOJVODINE

The rapid admission of information and communication technologies (ICT) into all the pores of social and economic life has (fortunately) included the education sphere: the ever-growing need for new knowledge acquisition methods unambiguously points to a need to step outside the established, analogue education systems into the digital, virtual educational space. Over the past few years, blogs, wikis, multimedia sharing and social networking sites have created a qualitatively new approach to knowledge, education and schooling. This article starts from the assumption that the advantages of Web 2.0 technologies can be channelled in favour of the common interest of all education process participants, and to that end, the authors have conducted empirical research into the level of willingness of key stakeholders (students, parents and teachers) in secondary education in Vojvodina to adopt contemporary, Web 2.0 based methods of knowledge transfer, sharing and adoption.Brzi ulazak informacijsko-komunikacijskih tehnologija (IKT) u sve pore društvenog i ekonomskog života obuhvatio je (srećom) i obrazovnu sferu: rastuća potreba za novim metodama usvajanja znanja neupitno ukazuje na potrebni iskorak iz dobro utvrđenih, analognih obrazovnih sustava u digitalni, virtualni obrazovni prostor. Proteklih nekoliko godina blogovi, wikiji, stranice za multimedijsko dijeljenje i društveno umrežavanje stvorili su kvalitetno novi pristup znanju, obrazovanju i školovanju. Ovaj rad polazi od pretpostavke da se prednosti tehnologija Web 2.0 mogu usmjeriti ka zajedničkom interesu svih sudionika obrazovnog procesa i s tim su ciljem autori proveli empirijsko istraživanje o tome koliko su ključni sudionici (učenici, roditelji i nastavnici) u srednjem obrazovanju u Vojvodini spremni usvojiti suvremene metode prenošenja, podjele i usvajanja znanja na načelima tehnologija 2.0

Critical success factors in ERP system adoption: comparative analysis of the private and the public sector

This research provides useful insight into differences in the perception of signifi cance and the degree of fulfi llment of Critical Success Factors (CSFs) of Enterprise Resource Planning (ERP) adoption between private and public sector organizations. The survey was conducted on a sample of 77 Serbian organizations, with approximately equal representation of those from the private and the public sector. A comprehensive list of CSFs, compiled as a result of an extensive literature review, was included in the questionnaire. The collected data and statistical procedures applied revealed the CSFs that differentiate the organizations from the two observed sectors. Involvement of end users in ERP adoption and implementation activities has proven to be the CSF in relation to which the assessments and attitudes of organizations from the two sectors differ the most. Results of this research indicate that differences between private and public sector organizations are more distinct in terms of their level of fulfi llment of ERP adoption CSFs than they are in terms of their assessment of CSFs’ signifi cance. This points to a conclusion that differences in the way of functioning and governance of organizations from these two sectors infl uence their ability to tackle the problems much more than their ability to recognize them. The practical contribution of this research is in providing some useful fi ndings that can greatly assist relevant stakeholders to achieve a higher success rate in an ERP adoption. In addition to responding to the initial research questions, this paper has also revealed new issues, suggesting the need for further research

What about the Chief Digital Officer? A Literature Review

Digital transformation is becoming more ingrained into everyday life and is a talking point among researchers today. It has been evident from the growing number of publications that have focused on various aspects of digital transformation in the last few years. Based on the number of papers published, one of them is of much less interest to researchers: the managerial role of Chief Digital Officer (CDO) inherent in digital transformation. Having this in mind, a systematic literature review was conducted to elucidate the CDO’s role, duties, and required competencies. In this paper, the results and conclusions of 22 papers are presented based on the search criteria outlined by the Web of Science and Scopus index databases. It is obvious that managing digital transformation is becoming more important as digital transformation affects almost every sector of business. The purpose of this study is to examine the position of Chief Digital Officer in terms of its position, role, and responsibilities as well as its necessary competencies. The results of this study could serve as the basis for future research in this area, which judging by the relevance of the topic, will certainly be more intensive
