Improving BPM with Blockchain Technology : Benefits, costs, criteria & barriers

Edrud, Pierre January 2021 (has links)
Syftet med denna studie var att förstå kriterier, barriärer, kostnader och fördelar som är förknippade med implementering av blockchain-teknik, och utifrån detta utforska hur blockchain-teknik kan förbättra BPM. Studien är av kvalitativ karaktär och gjordes sekventiellt genom att först genomföra en omfattande tvärvetenskaplig litteraturöversikt och därefter intervjua personer med erfarenhet från blockchain-teknik. Analysen gjordes med både en induktiv och deduktiv ansats där tematisk analys tillämpades. Resultaten från studien visar att blockchain-teknik kan minska transaktionskostnader, förbättra avstämning och verifiering, förbättra samarbetsprocesser och skapa förtroende och öppenhet samtidigt som de stöder organisationer med styrning av datasäkerhet, korrekthet av data, och minskade IT-kostnader till följd av förbättrad hantering med säkerhetskopiering av data, servrar och lagring. Stort fokus ligger för tillfället på smarta kontrakt där integrering av affärslogiken tillsammans med en förbättrad databasstruktur möjliggör förbättrat samarbete och automatisering av standardiserade affärsprocesser. Resultaten indikerar också brist på blockchain-ingenjörer, vilket påverkar utveckling och tillväxt. Studien belyser ett behov av ytterligare implementeringsstudier och att bättre skilja mellan de olika blockchain-typerna och de problem de kan lösa. Säkerhet, hållbarhet och interoperabilitet nämns ofta som utmaningar i den pågående diskussionen om blockchain. Detta är inte unikt för blockchain-teknik och mer nyanserade förklaringsmodeller krävs. Blockchain-teknik kan vara framtiden, och kan ersätta befintlig infrastruktur, i slutändan måste organisationer överväga vid vilken tidpunkt de bör börja tänka på att sätta blockchain på sin agenda, med de olika avvägningar som detta innebär. / The purpose of this study was to understand criteria, barriers, costs and benefits that are associated with implementing blockchain technology, and from this explore how blockchain technology can improve BPM. The study is of qualitative nature and was done sequentially by conducting an extensive cross-disciplinary literature review first, and then interviewed people with experience from blockchain technology. The analysis was done with both an inductive and deductive approach by doing a thematic analysis. The results from this study show that blockchain technology can reduce transactional costs, improve reconciliation, improve collaborative business processes and bring trust and transparency while supporting organizations with governance of data security, data consistency and reducing associated IT-costs with managing back-up of data, servers and storage. A lot of focus is currently centered around smart contracts, where incorporating the business logic together with an improved database structure allows for improved collaboration and automation of standardized business processes. The results also indicate a shortage of blockchain engineers, consequently impacting development and growth. The study highlights a need for further implementation studies and to better distinguish between the different blockchain types and the problems they can solve. Security, sustainability and interoperability are often mentioned as challenges in the current discourse on blockchain. This is not unique for blockchain and more nuanced explanation models are required. Blockchain technology may be the future and replace existing infrastructure, ultimately organizations have to consider at what point in time they should start thinking about putting it on their agenda and the associated trade-offs that comes with this. / <p>2021-06-06</p>

Studying the Opportunities of Blockchain Implementations in Electronic Transactions compared to the eIDAS Regulations / Undersöka möjligheterna för blockchain implementationer i elektroniska transaktioner jämfört med eIDAS regulationen

Hansson, Hanna January 2022 (has links)
The electronic identification regulation, eIDAS, and its trusted service providers are currently based on technologies that have been used for decades. The eIDAS and many others in the security industry have shown interest in newer technologies such as distributed ledgers and blockchain. This research looks into the current eIDAS regulation, its plans for future work, and how the current trusted systems could benefit from introducing blockchain into the solutions. Looking at new technologies is of importance to move forward but also making solutions more secure for the user with for example Self-Sovereign Identity solutions. The research was conducted through a literature review followed by interviews. A number of themes were identified to answer the research question. The findings were that blockchain is a viable technology to use but only if used in the right cases. A better understanding and knowledge of the technology is needed for new implementation to succeed and should not be rushed due to the hype of blockchain technology. / Se bif. fil
