This diploma thesis deals with the implementation of an information system for the operational management of small engineering companies with a focus on custom manufacturing. The thesis describes the current state of production control without support of the information system. Based on the identified shortcomings, the requirements and criteria for the new information system were developed. Then the selection of the information system and its implementation during production is dissected. At the end of the thesis there is described the production control with the support of the selected information system and the economic evaluation for acquisition of the information system.

The objective of this study has been to examine the portability of Moni- tor ERP System AB’s existing .NET Framework codebase to .NET Core. The study has been conducted by examining the portability of Monitor’s projects by using Microsoft’s .NET Portability Analyzer and visualizing the dependencies of projects by using AsmSpy to gain an understanding of what order projects need to be ported. An examination of used third-party libraries has also been conducted to see which libraries are not compatible with .NET Core. And an attempt to port Monitor’s root solution has been made as a proof-of-concept and to make test and build duration compar- isons between the ported solution and the old solution. The .NET Porta- bility Analyzer reported that 19 projects aren’t 100% compatible with .NET Core (+ Windows Compatibility Pack) where some projects have one miss- ing API call while others have many more. The third-party library examina- tion showed that two libraries are not compatible with .NET Core, the first is Dynamsoft Dynamic .NET TWAIN SDK which can probably be replaced with VintaSoft Twain .NET SDK, and SAP SQL Anywhere which doesn’t have a direct replacement. The results of the comparison show that test duration speeds improved on average by 22.5% with a peak of 67.6%, and build duration differences were negligible. Porting to .NET Core will not be easy, but if fixes for the 19 incompatible Monitor projects are completed and a replacement for SQL Anywhere can be found, then Monitor ERP System AB can make a successful port to .NET Core.

Placering av lager är generellt ett viktigt beslut för ett logistiksystem då lagerlokalisering påverkar flera faktorer i ett företag. Dagens företag befinner sig i en verklighet där konkurrensen är hård med globala aktörer som ser möjligheter att nå en bredare kundkrets. Med denna konkurrens blir företagets kundnöjdhet, kostnad och service viktiga aspekter för att sticka ut i mängden mot leverantörer och kunder. Syftet med denna studie har varit att föreslå en omstrukturering av ett reservdelslager för ett svenskt tillverkande industriföretag med en snabbt växande marknad, ett stort antal artiklar och globalt lokaliserade kunder. Fallföretagets vision var att minska kostnader, minska ledtider och öka kundnöjdheten vid en omstrukturering av centralt reservdelslager. För att besvara syftet och frågeställningar har en fallstudie genomförts bestående av intervjuer och observationer på fallföretaget och dess dotterbolag. Studien innehåller även intervjuer med två reservdelshanterare inom bilindustrin som bidragit med en bredd kring området reservdelar. Utifrån studiens intervjuer och observationer har ett nuläge hos fallföretaget skapats, vilket belyser att den geografiska placeringen i dagsläget inte spelar någon roll då försörjningskedjan har många utmaningar med befintligt arbetssätt. Detta ändrade fokuset hos författarna som istället började arbeta med utmaningarna som fallföretaget står inför. Dessa utmaningar behöver utvecklas för att en omstrukturering ska vara lönsam i framtiden och skapa en effektivare flödeskedja.  Utmaningarna handlar om att skapa en transparent kommunikation genom hela försörjningskedjan för att undvika onödigt extraarbete, missförstånd och onödiga ledtider i väntan på svar genom olika kommunikationskanaler. Studien belyser att den optimala placeringen av lagret kvarstår i Gävle med ett arbete att skapa en effektiv flödeskedja för att i framtiden omlokalisera ett centraliserat lager till Europa som bistår 500-1000 högst frekventa artiklarna. Slutsatsen för denna studie är att arbeta med dagens utmaningar och skapa möjligheten att göra det lönsamt att omlokalisera företagets reservdelslager efter företagets drivkrafter (minska kostnader, minska ledtider och öka kundnöjdhet). Exempel för hur företaget kan arbeta med dessa utmaningar är att integrera ett ERP-system mellan fallföretaget och varje dotterbolag, skapa en välutvecklad webshop med sprängskisser för varje komponent i hissen. Studien diskuterar genomgående om ett centralt eller decentralt lager. Centralt lager innebär ett till två större lager som innehåller både låg-och högfrekventa artiklar som är geografiskt placerat separat från dotterbolagen. Decentraliserat lager innebär ett mindre lager lokaliserat i dotterbolagets lokaler som inkluderar dotterbolagets mest frekventa artiklar.

Digitaliseringen kommer sannolikt att ställa andra krav på dagens organisationer. Molnbaserade ERP-system efterfrågas i allt högre grad, vilket innebär att organisationer måste anpassa sina aktiviteter i enlighet med de molnbaserade ERP-systemen. Denna studie undersöker hur åtta konsulter arbetar med organisationer för att ta dem från plastbaserade ERP-system till molnbaserade ERP-system. De åtta respondenterna, som bidrog med det empiriska materialet, representerar olika företag. Studien finner stöd för delar av den teoretiska bakgrunden, och andra delar av studien stödjer inte tidigare forskning inom området. Det finns empiriskt stöd för institutionaliseringsteori och för vad organisationer strategiskt behöver uppnå för att erhålla konkurrensfördelar. Studien presenterar olika utmaningar inom kontextvariablerna: organisationsstruktur, organisationssystem och strategi. Resultatet av studien visar att om organisationer framgångsrikt ska kunna övergå till molnbaserade ERP-system, måste organisationer vara flexibla, vilket organiska organisationsstrukturen är. Resultatet visar också att det finns utmaningar inom den normativa isomorfismen, vilket innebär ett motstånd från organisationens IT-avdelning. Slutsatsen i denna studie är att konsulter som arbetar med organisationer som genomför implementeringar av molnbaserade ERP-system måste överväga kontextvariabler för att få en förståelse för vilka organisatoriska mekanismer som påverkar vägen till molnet. / The digitalization will most likely require other demands on today's organisations. Cloudbased ERP-systems more and more becomes a fact in organizations, and this will mean that organizations have to adapt their activities accordingly. This study examines how eight konsultants work with organizations to take them from on-premise ERP-systems to cloudbased ERP-systems. The eight respondents, who provided empirical information represent different companies. The study finds support for parts of the theoretical background, and other parts of the study does not support earlier research in within the field. There is empirical support for institutionalization theory and for strategy needs to achieve competitive advantages.The study presents different challenges within the contingency variables: organizational structure, organizational systems and strategy. The result from the study is that in order to successfully transcend to the cloud organizations need to be flexible, which the organic organizational structure is. The result also shows that there are challenges within the normative isomorphism, which includes resistance from the organization's IT-department, which has a high probability to occur. The main contribution of this study is that konsultants who work with organizations that is implementing a cloudbased ERP-system needs to consider contingency variables in order to gain an understanding of what organizational mekanisms will affect the journey to the cloud.

Historically, system integration of ERP system and other existing IT systems within anorganization has always been a complex challenge, both technically and organizationally. Inmany cases, the budget for system integration corresponds 30-40% of the whole IT budget.Since system integration accounts for a large part of the cost during acquisitions andimplementation of an ERP system, companies are interested in the challenges that exist duringsystem integration, to simplify the integration process and hence reduce the costs. Tounderstand the challenges, a case study at Company X has been performed. The ERP systeminvestigated in the case study is Microsoft Dynamics AX.The purpose with this study is to investigate challenges that exist in large organizations duringsystem integration of ERP system and other IT systems that exist in the organization andthereby understand how integration can be developed in a more efficient way.The study entails an extensive literature study and two rounds of data collection throughqualitative interviews.The results showed that the challenges that exist at Company X are mainly organizational.Technical challenges coexist but they have a much less significant impact than theorganizational challenges. This can be explained by that there has been a heavier focus onsolving the technical related problems and maybe to some extent neglected the impactorganizational problems can have on system integration. Possible actions includes centralstrategy concerning how to work with Dynamics AX, it’s growth and future initiatives,policies and framework regarding working methods, increased authority and decision rights tothe group working with AX as well as minimize customizations and own development.

It is proved that cloud computing has many benefits, and cloud services with flexible licensing model and cost saving features bring opportunities to enterprise's IT operations. Conventional ERP system, an important component of enterprises, is impacted by on-demand cloud services also. Integrating conventional ERP system with cloud services becomes a trend because it brings new processing capabilities without introducing significant changes to existing system. But previous studies about integrating ERP and cloud usually focused on SaaS (Software as a Service). PaaS (Platform as a Service) and IaaS (Infrastructure as a Service) are not discussed much. People sometimes even confuse cloud service with SaaS. Therefore, the objective of this paper is to present a framework that can describe respective implications of integrating ERP with three types of cloud services: SaaS, PaaS and IaaS. Qualitative methods such as systematic literature review and interviews are adopted to execute the research, so data collected through different sources can complement each other in order to support presenting the framework of integrating conventional ERP system and cloud services. The integration at SaaS level is for achieving immediate business value and productivity enhancement. At PaaS level the objective of integration is to enhance software development life cycle management. And the main integrating intent at IaaS level is to enable scalability and reliability of hardware resources without changing existing IT infrastructure. Furthermore, challenges and opportunities for integrating ERP with different cloud services are studied and motivation is derived from analyzing. Finally the key points are arranged in the presented framework of integration between conventional ERP systems and cloud services.
