Water treatment plant Bzenec Přívoz represents important supply of potable water for Hodonín district. After a longtime operation it was in 2008-2010 reconstructed in order to make water treatment technology more effective. The basic step was dividing technology into one stage and two stage water treatment for particular spring areas of ground water. The character of raw water requires effective removal of iron and manganese, therefore intensification and optimization of operating parameters were the purposes of the project. Installation of new aerators and hyperboloid stirrers in flocculation tank required an operating tests for proving of high technological efficiency while the operating costs were decreased. The water treatment process was completly automatized, which made the operation easy and minimized human element impact. Results of the reconstruction are more effective water treatment and a distinct decrease of operating costs.

Configuration management is a process for establishing and maintaining consistency of a product's performance, as well as functional and physical attributes with regards to requirements, design and operational information throughout its lifecycle. The way configuration management is implemented in a project has a huge impact on the project’s chance of success. Configuration management is, however, notoriously difficult to implement in a good way, i.e. in such a way that it increases performance and decrease the risk of projects. What works well in one field may be difficult to implement or will not work in another. The aim of this thesis is to present a process for optimizing configuration management processes, using a telecom company as a case study. The telecom company is undergoing a major overhaul of their customer relationship management system, and they have serious issues with quality of the software that is produced and meeting deadlines, and therefore wants to optimize its existing CM processes in order to help with these problems. Data collected in preparation for the optimization revealed that configuration management tools were not used properly, tasks that could be automated were done manually, and existing processes were not built on sound configuration management principles. The recommended optimization strategy would have been to fully implement a version handling tool, and change the processes to take better advantage of a properly implemented version handling tool. This was deemed too big a change though, so instead a series of smaller changes with less impact were implemented, with the aim of improving quality control to minimize the number of bugs that reached production. The majority of the changes had the purpose of replicating the most basic functions of a version handling tool, as well as automating manual tasks that were error prone. / Configuration management är en process för att etablera och bevara konsistensen hos en produkts prestanda, så väl som funktionella och fysiska attribut med avseende på krav, design och driftinformation genom dess livscykel. Hur konfigurationshantering implementeras i ett projekt har en avsevärd betydelse för huruvida projektet kommer att lyckas eller ej. Configuration management är dock ökänt för att vara svårt att implementera på ett bra sätt, d.v.s. så att det ökar prestandan och minskar risken i projekt. Det som fungerar bra inom en bransch kan vara svårt att implementera eller fungerar inte i en annan. Målet med denna studie är presentera en process for optimering av konfigurationshanteringsprocesser där ett telekomföretag använts som en fallstudie. Telekomföretaget genomgår en stor upprusting av sitt kund-system. Företaget har stora problem med kvalitén på den mjukvara de tar fram och att möta levaranstidpunkter, och vill därför förbättra sina processer för att komma till rätta med dessa problem. Data som samlades in inför optimeringen visar att CM-verktyg ej användes på korrekt vis, arbetsuppgifter som kunde automatiserats gjordes manuellt, och existerande processer byggde ej på best practices inom CM. De rekommenderade optimeringsstrategin var att implementera och använda ett versionhanteringssystem, och ändra processerna för att dra nytta av fördelarna med ett korrekt implementerat versionshanteringssystem. Detta ansågs dock vara en allt för stor förändring, så istället genomfördes ett antal mindre ändringar med mindre påverkan, med målet att förbättra kvalitetskontrollerna och minimera antalet fel som nådde produktion. Majoriteten av ändringarna hade syftet att replikera de mest grundläggande funktionaliteten hos ett versionhanteringsverktyg, så väl som att automatisera felbenägna manuella rutiner.

Artificiell intelligens överträffar alltmer mänsklig arbetskraft och detta skapar oro över att redovisningsekonomernas arbetsuppgifter kommer ersättas helt. Covid-19 har tvingat organisationer till distansarbete och i samband med det har implementeringen av digitala verktyg har ökat. Frågan är hur detta har påverkat redovisningsekonomer? Studier syftar till att undersöka och skapa förståelse för hur redovisningsekonomernas yrkesroll förändrats. Studiens syfte har besvarats genom ett samspel mellan teori och insamlad empiri från 12 redovisningsekonomer samt tre experter inom digitalisering. Studiens resultat visar att krisen har tvingat redovisningsekonomerna till ett mer digitalt arbetssätt i samband med att distansarbetet ökat. Resultatet visar att redovisningsekonomerna uttrycker osäkerhet inför den framtida rollen och rädsla för att bli av med sitt arbete. Studien konstaterar att osäkerhet och rädsla grundas i okunskap eftersom redovisningsekonomerna inte är medvetna om digitaliseringens fördelar. Automatisering av arbetsuppgifter leder till att nya mer kvalitativa uppgifter skapas och dessa karaktäriseras av högre komplexitet. Förändringarna kräver engagemang och eget intresse att utvecklas mot en ny och betydligt mer omfattande roll. Den nya yrkesrollen kräver högre social kompetens, analys- och problemlösningsförmåga samt mer systemkunskaper. Studien konstaterar att utbildade redovisningsekonomer har bättre förutsättningar att ta sig an de mer komplexa arbetsuppgifterna. Den ökade digitaliseringen är därför till större fördel för utbildade ekonomer än outbildade. Resultatet visar att större organisationer i högre grad är mogna inför att ta till sig nya digitala lösningar och har således en högre grad av teknikmognad. Dessa organisationer har även i större utsträckning antagit en tydlig identitet inom teknologi. Större organisationerna frigör mer resurser i form av tid och pengar till både digitaliseringsprojekt och utvecklingsstrategier. Redovisningsekonomer verksamma inom större organisationer är mer positiva och engagerade i digitaliseringsfrågor. Resultatet i examensarbetet visar att större resurser för nya ansvarsområden inom digital utveckling är fördelaktigt för organisationen och redovisningsekonomernas personliga utveckling. / Artificial intelligence is increasingly surpassing the human labor and this creates concerns among the accountants that their tasks will be completely replaced. Covid-19 has forced organizations to convert their business to remote work and this has led to increased implementation of digital solutions in the accountants working methods. The question is how this has affected the accounting profession? To answer this question, the study aims to investigate and create an understanding of how the accountants professional role has changed. The purpose of this study has been answered through the interplay between theory and collected empirical data from 12 accountants and three experts in digitization. The results show that the crisis has forced accountants to take on more digital working methods due to the circumstances of social distance. The results show that accountants express uncertainty about the future role and fear of losing their jobs. Results of the study shows that the accountants uncertainty and fear are based on deficiencies in their knowledge about the digitalization benefits. Automation with artificial intelligence contributes to new and more qualitative work tasks that are characterized by higher degree of complexity. Changes of the accounting role requires commitment and self-interest to develop towards a new and more comprehensive role. The new role of accounting requires higher social skills, analytical and problem-solving skills as well as the demand for computer system knowledge increases. The study states that educated accountants are in a better position to take on the more complex tasks. The increased digitalization is therefore to a greater advantage for educated accountants than uneducated ones. The results show that larger organizations are more mature for adopting new digital solutions and therefore have a higher degree of technological maturity. These organizations have also taken on a distinct technology-identity. Larger organizations also spare more resources such as time and money for digitization projects and development strategies for the accountants. Accountants who work in larger organizations have a more positive attitude to and are more involved in questions regarding digitization. The result of the study shows that digital development responsibilities that are allocated given resources are both beneficial for the organization and beneficial for the accountants personal development.
