Enterprise Resource Planning Systems as a Service: Hur genomförs en framgångsrik implementation?
Denna uppsats har sin utgångspunkt i den tekniska evolution som har skett i affärssystemens värld. Syftet var att undersöka och beskriva implementat-ionsfasen av ett Enterprise Resource Planning System som tillhandahålls som en tjänst via internet. Fokus var att identifiera framgångsfaktorer för implementationen med hjälp av ett fallstudiebaserat tillvägagångssätt där tonvikt legat på intervjuer och andrahandsmaterial. Undersökningen visade att bland annat valet av ett för organisationen passande system, en omfattande verksamhetsanalys, implementeringshjälp av konsulter samt anpassning av affärsprocesser är viktiga faktorer för en framgångsrik implementation. Därtill såg vi att en tydlig projektplan, en Project Champion och dedikerade resurser också var viktiga faktorer för framgång..
Koordination genom informationsteknologi
Informations- och kommunikationsteknologins (IKT) utveckling har medfört nya sätt att organisera och genomföra arbete. Kommunikation och i slutändan dess innebörd information har förlängts i form av både tid och rum, då människan inte i samma utsträckning är beroende av en specifik tid och plats för att kommunicera med andra. Att organisera innebär i stora drag att dela upp ett övergripande mål i mindre delar (aktiviteter) samt fördela arbetet (vem gör vad och i vissa fall även hur). Att koordinera innebär att hantera beroenden mellan aktiviteter, som organisationeringen skapar. I och med att tekniken bidrar med nya sätt att kommunicera och organisera förändras även möjligheterna till att koordinera, dock är det problematiskt att veta hur tekniken bör användas för att på bästa sätt stödja detta, alltså vilken roll IKT bör ha i koordinationen.
Standardisering kontra flexibilitet : En fallstudie av utvecklingsprocesser
Process standardization is a topic that has generated a lot of research and literature. At first, the focus was on production; today processes are used in all different kind of business areas.The aim of this study has been to analyze how processes can be applied on development businesses and how IT systems affect the result of the process. To accomplish this, we have asked questions such as what standardization is in a development process? Why are the processes standardized? What difficulties can appear with standardization? And how the IT-systems affect the result of the process?To answer these questions, we have preformed a case study on Saab. Saab is a well know Swedish company who are working with a project called the GMS-project, where they develop processes to cover the whole company´s business areas.The literature gives the reader an understanding of processes and standardization.
"Harry Potter är inte lämplig i skolan" : En jämförande studie mellan serbiska och svenska lärares syn på litteraturundervisning.
This thesis is about Swedish and Serbian teachers and their views on how literature should be taught to students in high school. The twist is that these teachers live in two different European countries, and work under two different educational systems. Three of them work in Stockholm, Sweden and the other three in Belgrade, Serbia. The purpose of this thesis was to find similarities and differences in the practice of teaching literature among teachers in these two different educational systems. The teachers were interviewed separately and spoke freely about their views and methods when teaching literature.
Private Equity-bolags styrning av portföljbolag; En fallstudie av värderingsmodellens översättning till olika organisationsnivåer.
The aim of this thesis is to investigate how a valuation model of a Private Equity firm is interpreted into a management control system within the company's different organizational levels. A case study was developed based on the infra-net company Eltel. The management control systems developed by Malmi and Brown (2008)(1) was used to characterize the control systems at each organizational level. The building blocks of this system are planning, cybernetic, reward/compensation, administrative and culture. Miller and O'Learys (2007)(2) theory of mediating instruments and technology roadmaps was applied to analyze the mediating process of the valuation model.
Funktionsupphandling av solelanläggningar
This thesis aims to contribute to improved functional procurement of photovoltaic systems, PV systems. Functional procurement means that criteria concerning a function are set rather than specifying technical details or products. Possible advantages and difficulties in using functional procurement have been analyzed by interviews, simulations and a case study. Electricity production and surplus production for different scenarios have been simulated via MATLAB. The MATLAB script was also used to generate rules of thumb on feasible solar fraction for six different load profiles; a church, a farm, a car mechanic, an office, an industry and an apartment building.
Hastighets- och positionsinterface för motorer
The environmental requirements and laws on combustion engine emissions are very tough today andthey will become even more stringent in the future. To achieve these requirements there are highdemands on the control systems for these engines. An improved precision in the measurement of anengine's speed and position gives the electronic control system an even better timing when it comes tofuel injection and ignition. This makes the engine more fuel efficient, reducing the emissions. This thesisis part of a collaborative project between Hoerbiger Control Systems and subsidiaries.
Vad säger bilden?: En utvärdering av återvinningseffektiviteten i ImBrowse
The aim of this master thesis is to evaluate the performance of the content-based image retrieval system ImBrowse from a semantic point of view. Evaluation of retrieval performance is a problem in content-based image retrieval (CBIR). There are many different methods for measuring the performance of content-based image retrieval systems, but no common way for performing the evaluation. The main focus is on image retrieval regarding the extraction of the visual features in the image, from three semantic levels. The thesis tries to elucidate the semantic gap, which is the problem when the systems extraction of the visual features from the image and the user?s interpretation of that same information do not correspond.
LOST IN TRANSLATION: Kommunikation förlorad i informationssystem
This study investigates communication and data in information systems. The paper deals, more specificly, with communication in a CRM-system implemented in a Swedish-founded company in Beijing, China. It discusses cultural, political, linguistic and gender based dilemmas that can arise from the use of a CRM-system in an international and bilingual environment. Fifty-nine interviews were conducted in Sweden and in China, either in Swedish or English. The result of this study shows that communication in the information system is affected by factors, that are not originated in technical shortcomings of the system, but rather from cultural, political, linguistic and gender based pre-knowledge among individuals.
Vertikala samarbeten : Vad hindrar aktörerna på den svenska marknaden för dagligvaruhandel att samarbeta avseende informations- och kunskapsutbyte?
Bakgrund: Genom vertikala samarbeten i värdekedjan kan konkurrensfördelar skapas och parterna kan dra nytta av varandras kompletterande resurser. Brittiska aktörer inom dagligvaruhandeln har genom samarbeten uppvisat stora vinster, men på den svenska marknaden förekommer samarbete i begränsad utsträckning. Syfte: Studiens syfte är att explorativt undersöka och ge ett kunskapsbidrag kring faktorer som hindrar fördjupade vertikala samarbeten mellan handelsaktörer och leverantörer på den svenska marknaden för dagligvaruhandel. Genomförande: Empirisk data har samlats in genom totalt tolv intervjuer med handelsaktörer och leverantörer, varav fyra med brittiska aktörer. Studien är en komparativ fallstudie med explorativ inriktning.
Ändring av befintligt ridhus : Gävle Fältrittklubb
In past decades information technology has changed the conditions of organizations, not at least within the industry. Advanced IT systems have become a fact in order to cope with rapid changes in the market and to effectively manage an organization?s knowledge. When organizations became more flexible and customized expectations from customers and stakeholders also become higher. These expectations and guidelines are documented in a company?s management system, which can be designed differently depending on what standards the company chooses to implement.
Alternativ uppvärmning av reningsverket på Utö - En studie av energibesparingsmöjligheterna i syfte att minska uppvärmningskostnaderna
The projects objective is to find an alternative method of heating (the current method being via electric heating) the sewage treatment plant on the island Utö in Stockholm?s archipelago in order to reduce the energy consumption and ultimately the cost for heating the plant. The project is given by ?Skärgårdsstiftelsen? (The Archipelago Foundation) and is a part of the larger EU-project ?Green Islands?.A model for the plants total heating demand is established in order to get a good perception of how much money can be saved using alternative heating methods. The heating demand model gives an annual heating demand of approximately 32 500 kWh and a maximum heating power demand of around 24,7 kW.
Termisk analys av kompakta jordvärmesystem - Sensitivitetsanalys och korrektions faktorer baserat på fältmätningar i referensanläggningar i Östergötland
Chapter 1 defines the aim of the project and gives a general orientation about ground heat extractors. In chapter 2 physical processes that could be expected to be involved in the heat transport around a ground heat exchanger are discussed. It is shown from a literature study what amount of moisture transport due to thermal gradients there could be expected in a ground heat exchanger. The conclusion is drawn that the moisture gradient (Sr) is of same magnitude as the driving temperature gradient (°C). At the expected amount of increased moisture around the pipes the moisture transport could be considered to have a little effect on the brine temperature.
Uppföljning inom ett vårdvalssystem - En fallstudie av uppföljningen av husläkaruppdraget i Stockholms Läns Landsting
This study aims to examine the effect the evaluation system used by the Stockholm County Council, has on how the healthcare providers themselves conduct the evaluation regarding their own operations. This is done through a qualitative case study of the evaluation systems of the Stockholm County Council and of four primary healthcare producers concerning one primary healthcare contract. The evaluation systems were analysed using Merchant and Ver der Stede's (2007) framework for different types of control. In order to give a more detailed picture this framework was complemented with different types of performance measurement. The evaluation that the Stockholm County Council conducts was found to have little influence on the providers own evaluation with the exception of the quality indicators that are rewarded with a monetary bonus..
Business intelligence inverkan på styrning av affärsprocesser: Fallstudie på en medelstor organisation där studien beskriver aktörernas förväntningar på business intelligence
De dynamiska förhållanden som råder för företagen i omvärlden. Har bidragit till att beslutfattare inom företagen har påbörjat att tillämpa olika typer av informationssystem för att effektivisera beslutsprocesser och informationshanteringsprocesser Den ständigt pågående ökning av information som erhålls via dagens informationssystem kan utlösa information overload, som i sin tur skapar ett förvirrat och dysfunktionellt beteende hos beslutfattare. Genom att tillämpa business intelligence bidrar till att information overload problematiken reduceras markant. Studien har till ambition att med hjälp av de befintliga teorierna inom ämnesområdet upprätta en egen analysmodell i syfte för att kunna estimera studiens åtta stycken aktörers beteendemässiga avsikt till att tillämpa business intelligence. Det genom att beskriva och tolka aktörernas syn på hur business intelligence kan komma att inverka på den framtida styrningen av affärsprocesserna.
