Abstract: Background: The software product lines (SPL) enable development teams to fully address a systematic reuse of shared assets to deliver a family of similar software products. Mobile applications are an obvious candidate for employing an SPL approach. This paper presents our research outcomes, based on empirical data from an industry-level development project. Two development teams were confronted with the same functionalities set to be delivered through a family of native mobile applications for Android and iOS. Methods: Empirical data was gathered before, during and after a year of full-time development. The data demonstrate the impact of a SPL approach by comparing the SPL and non-SPL multiple edition development. One family of products (Android apps) was developed using an SPL approach, while another (iOS apps), functionally the same, was developed without employing an SPL approach. The project generated a volume of raw and aggregated empirical data to support our research questions. Results: The paper reports a positive impact of an SPL approach on product quality (internal and external) and feature output per week. As data shows, it also increases the delivery of functionalities (240% in 6 more editions), while investing the same amount of effort needed for a single-edition development. As a result of system-supported separation of development and production code, developers had a high confidence in further development. On the other hand, the second team delivered less new functionalities, only two new application editions, and lower software quality than the team that manages multi-edition development by employing an SPL approach.

Abstract: Magistrsko delo temelji na spremljanju »zdravstvenega stanja« v agilnih ekipah. Sektor informacijske tehnologije je preplavil agilni način dela zaradi principov in praks, ki jih prinaša. Vendar ob tem lahko nastopijo tudi težave, ki vplivajo na zadovoljstvo in učinkovitost posameznikov v organizacijah. Namen dela je podrobno pregledati različne modele, ki so namenjeni spremljanju »zdravstvenega stanja« in analizirati, kateri faktorji pripomorejo k zadovoljstvu, motivaciji ter učinkovitosti članov agilnih ekip. Hkrati so predstavljeni tudi rezultati empirične raziskave, izvedene v Sloveniji, pri podjetjih v sektorju informacijske tehnologije, ki se poslužujejo agilnih metodologij. S pomočjo te raziskave so bili pridobljeni rezultati, ki nakazujejo dejansko stanje ekip in služijo kot vodilo za priporočila, ki olajšajo in izboljšujejo delovanje agilnih organizacij.
Keywords: agilne ekipe, zdravstveno stanje ekip, zadovoljstvo zaposlenih, učinkovitost ekipe, težave v agilnih ekipah, agilni razvoj, ohranjanje zavzetosti

Abstract: V zborniku sedemindvajsete konference OTS 2024 so objavljeni prispevki strokovnjakov s področja informatike, v katerih so predstavljena nova spoznanja in trendi razvoja, vpeljave, prilagajanja ter upravljanja informacijskih rešitev, kot tudi konkretni uspešni pristopi in dobre prakse. Prispevki naslavljajo področja sodobnih arhitekturnih izzivov, klasične, generativne in globoke umetne inteligence, sodobnih spletnih ali mobilnih uporabniških vmesnikov, kot tudi tradicionalnih, brezstrežniških in decentraliziranih zalednih sistemov v oblaku. Tematike prispevkov obsegajo tudi zagotavljanje ustreznega skalabilnega okolja zanje ter avtomatizacijo testiranja, merjenje kakovosti in dostavo s proaktivnim naslavljanjem najpogostejših kibernetskih napadov. Rdečo nit prispevkov predstavljajo podatkovne tehnologije, ki so zastopane v obliki klasičnih podatkovnih baz, podatkovnih jezer ter učinkovitega zbiranja, obdelave in vizualizacije velepodatkov. Prispevki tako še naprej omogočajo boljšo povezanost IT strokovnjakov, informatikov, arhitektov in razvijalcev IT rešitev in storitev, kot tudi akademske sfere in gospodarstva.
Keywords: programsko inženirstvo, informacijski sistemi, informacijske rešitve, digitalna preobrazba, razvoj mobilnih in spletnih rešitev, arhitekture v oblaku, podatkovne tehnologije, poslovna inteligenca, umetna inteligenca in strojno učenje, obdelava velepodatkov in podatkovnih tokov, metode agilnega razvoja, tehnologije veriženja blokov, kibernetska varnost

Abstract: Glavni cilj tega diplomskega dela je bil raziskati in preučiti zmožnosti gRPC kot ogrodja za gradnjo komunikacije med storitvami, v primerjavi z drugimi arhitekturnimi stili. Analizirali smo med pripravo diplomske naloge ustrezno literaturo/vire, ki so nam zagotovili potrebne informacije za eksperimentalno fazo. Za preverjanje teoretičnih trditev smo zasnovali in implementirali vzorčno aplikacijo z uporabo podanih arhitekturnih stilov.
Keywords: gRPC, REST, mikrostoritve, proto, porazdeljenih aplikacij

Abstract: Digitalisation nowadays impacts business environments significantly. Therefore, if higher education wants to educate students properly for a successful career path, the business and economics curriculum must be enriched with innovative teaching approaches covering actual topics, such as, for example, the implementation of the ERPsim business simulation, a representative of serious games. The ERPsim business simulation is based on SAP ERP, and is aimed at teaching ERP concepts. It covers different business processes, and allows students to learn using a hands-on approach, simulating real-life scenarios. The presented research focuses on using an ERPsim business simulation as the introduction to the course. The simulation was implemented to ease the introduction of ERP and IT concepts to the business and economic oriented students. Considering the positive effects of serious games and gamification, our research was formed and focused on knowledge acquisition and future student engagement. We researched whether participation in the introductory simulation results in significant knowledge gain and impacts students’ future course engagement. The data were gathered using a self-assessment questionnaire before and after an introductory simulation. The results were highly positive, confirming many positive aspects of business simulation, among others, significant knowledge increase in the domains of business process and ERP transactions, and in the domain of technical knowledge for SAP ERP. The results confirmed that the introductory simulation is appropriate for introducing ERP concepts to newcomers, and, nevertheless, confirmed the positive impact on their intent on future course engagement.
Keywords: business simulation, knowledge acquisition, course engagement, ERPsim, SAP, gamification
