Limited research has been conducted on how system administrators actually can affect information systems (IS) after they have been implemented; hence, this study examines how system administrators can affect IS success in an implemented IS. The study identified a system administrator´s affect on the three IS quality dimensions in the DeLone and McLean IS success model. The empirical findings was based on a single case study where the data was collected through interviews with the system administrator and the system assistants, but also through a questionnaire answered by the users of the IS. The empirical findings suggested that the system administrator can affect IS success through the IS quality dimensions both directly and indirectly. The system administrator´s affect on IS success proved to be highly dependent on the external system vendor and the structure of the internal support unit.

Das Thema dieser Arbeit ist die spektraltheoretische Untersuchung von zufälligen Operatoren, die zu einem minimal ergodischen bzw. strikt ergodischen Delone dynamischen System assoziiert sind. Es werden kontinuierliche sowie diskrete Modelle untersucht. Diese Modelle sind mathematische Modelle zur Beschreibung von Festkörpern, bei denen die Punkte der einzelnen, in einem Delone dynamischen System enthaltenen, Delone-Mengen die Atompositionen eines Festkörpers beschreiben. Delone-Mengen, die in einem minimal ergodischen Delone dynamischen System enthalten sind weisen eine sehr hohe Ordnungsstruktur auf, sind aber nicht notwendigerweise periodisch. Sie können daher zur Modellierung von Quasikristallen verwendet werden. In dieser Arbeit wird das Spektrum der assoziierten Operatoren im kontinuierlichen sowie im diskreten Fall untersucht.

For many years researchers have been troubled with the evaluation of Information Systems (IS) concluding to a lack of understanding as to the time, methods and tools for measuring the impact of IS on organisational performance. Motivated by this lacuna in the literature, this thesis explored the relationship between Information Systems’ Effectiveness and Organisational Performance. The theoretical framework is based on the Delone and McLean’s (D&M) IS success model which is widely adopted in the IS research. Based on a comprehensive literature review on the older and more recent studies the research framework incorporated several new items used by researchers for the measurement of the D&M dimensions. Following a web survey on 168 Greek firms this study sheds some light into the IS field by focusing on how IS effectiveness measures affect Organisational Performance. Data for this study was collected by means of a web-link questionnaire and a sample of 700 companies of different sizes operating in various industries. Many descriptive statistics of academic and managerial importance were produced. Following a correlation analysis and Exploratory Factor Analysis, 15 factors were used for Multiple Regression analysis conducted to test a number of hypotheses around the relationship between the dependent construct (organisational performance) and the independent construct (IS effectiveness). This thesis contributes to existing research in the following ways. First, this study extends our knowledge on IS effectiveness as we adapted and modified DeLone and McLean's model of IS success to incorporate new variables from recent research. The results indicate a significant statistical link between IS effectiveness and performance measures. Second, it provides a holistic framework for measuring Organisational Performance with financial and non-financial variables. Finally, the study presents findings from Greek companies that have adopted IS providing practioners with advice for the practices that can lead to possible and realistic benefits.

No / The purpose of this paper is to examine the success (by measuring intention to use and user satisfaction) of the online public grievance redressal system (OPGRS) from the perspective of the citizens of India. The success of this e-government system is examined using an integrated IS success model. The model developed includes the constructs such as system quality, information quality, service quality, perceived usefulness, perceived ease of use, perceived satisfaction, perceived risk, and behavioral intention. The proposed integrated research model of IS was validated using the response taken from 419 citizens from different cities of India. The empirical outcomes provided the positive significant connections between all 12 hypothesised relationships between eight constructs. The empirical evidence and discussion presented in the study can help the government to improve upon and fully utilise the potential of the OPGRS as a useful tool toward a transparent and corruption free country.

Information system is a crucial topic in today’s business world. Without a proper information system, it is very difficult to compete on the market. The purpose of the study was to analyze the impact an information system has on the users work and how those factors are assessing the users’ readiness to change to e.g. switch from an existing information system to a new more advanced one. The study was based on the DeLone and McLean IS success model and a single case study was conducted with an inductive research approach. The empirical data has been gathered through semi-structured interviews and the findings show that reliability, response time and IT service of the IS system are the factors with the most influence on the user’s perceived readiness to change. Moreover, the users are not ready to change the current information system that is running within the company for a more advanced one. Position, technical skills and top management are all impacting the user’s readiness to change. Organizationscan use these findings to analyze the users’ satisfaction, their behavior and readiness to face the future changes.

In an era of digital convergence, people in related fields are devoted to activities of digitalization, especially in digital TV. This research is based on the Information System Success Model from Technology Acceptance Model (TAM) and aimed to understand the factors that affect user satisfaction and acceptance behavior. The researcher adopts the methodology of questionnaire survey. After statistical data analyses, the results show the main factor that influences MOD users¡¦ intention to use is perceived usefulness. Furthermore, perceived usefulness is influenced by perceived ease of use and user satisfaction. Three factors related to perceived ease of use and user satisfaction are program content quality, system quality and service quality of MOD. However, the influence of information quality is not significant. This research successfully constructs a technology acceptance model for MOD development and contributes for reference not only to future researches on users concerning innovative technologies but also to specific guidance for MOD operators to improve their services, expediting the development of digital TV in Taiwan.

Denna studie och uppsats har behandlat samt fokuserat på att synliggöra användarproblem och bearbeta dessa genom bakomliggande teorier kring olika systemegenskaper. Studien utgår från det aktuella administrationsverktyget Everyware. Verktyget Everyware används idag av tidningar och mediehus för att bygga upp och underhålla webbtidningar. En ständig ökning av digital nyhetspublicering bidrar till en konkurrens inom tidnings- och mediebranschen. Detta betyder i sin tur att branschen vill publicera sina nyheter så snabbt och smidigt som möjligt. Detta har varit en bidragande faktor till studiens syfte. Syftet med studien har varit att ta fram ett nytänkande gränssnittsförslag som utifrån användaren ska upplevas som lätthanterligt, smidigt och responsivt. Det teoretiska ramverk som står till grund för studien är baserat på teorin IS Success Model. Med denna teori har studien undersökt vilka framgångsfaktorer ett informationssystem, enligt användarna, bör tillhandahålla. Som komplement till teorin har studien även använt sig av vetenskapliga områden som användarupplevelse, användbarhet och användarnytta. Genom både kedje- och ändamålsenligt urval har åtta potentiella användare av aktuellt verktyg involverats. Det empiriska materialet har samlats in genom individuella semistrukturerade intervjuer samt en gruppintervju. Utifrån det empiriska material som samlades in har sedan tydliga mönster tagits fram för att senare vidareutvecklas och bearbetas vidare i arbetsprocessen. En kategorisering utifrån olika upplevelser kring användandet av det aktuella verktyget, har tagit studien vidare mot gränssnittsarbetet. För att kunna skapa gränssnittsförslag krävdes en analys av det resultat som framkommit. En innehållsanalys och ett affinitetsdiagram skapades för att ta reda på primära önskemål hos användarna gällande administrationsverktygets egenskaper. Utifrån analysen kunde slutligen ett förslag på ett nytänkande gränssnitt för administrationsverktyget Everyware tas fram. Resultatet av denna studie har visat att användare av ett administrationsverktyg, för skapande av webbtidningar, är beroende av att verktyget tillhandahåller särskilda system, information och serviceegenskaper. Dessa egenskaper kan i sin tur leda till förmåner för användare av administrationsverktyget, tidningsbranschen samt läsarna. / This study has addressed and focused on visualizing user problems and processing them through underlying theories about different system properties. The study is based on the current administration tool Everyware. The tool is today used by newspapers and media houses to build and maintain web magazines. An ongoing increase in digital news publishing contributes to competition in the newspaper and media industry. This in turn means that the industry wants to publish news as quickly and smoothly as possible, which has been a contributing factor to the purpose of the study. The purpose of the study has been to develop a new-minded interface proposal which, according to the users, should be experienced as easy to use, smooth and responsively. The theoretical framework for the study is based on the theory IS Success Model. With this theory, the study has investigated what success factors an information system, according to users, should provide. As a complement to the theory, the study has also used scientific areas such as user experience, usability and utility. Through different methods has eight potential users of the current tool been involved. The empirical material has been collected through individual semi structured interviews and a group interview. Based on the collected data, patterns have been developed for further development and adaption in the work process. A categorization based on different experiences regarding the use of the current tool took the study further towards the interface proposal. In order to create interface proposals, an analysis of the result that was obtained was required. A content analysis and an affinity diagram were created to determine primary requirements of users regarding a management tool properties. Based on the analysis, a proposal of a new interface for the Everyware administration tool could finally be made. The result of this study has shown that users of administration tools are dependent on that the tool are providing specific system, information and service characteristics. These characteristics can in turn lead to net benefits for users of the administration tool but also the newspaper industry and the readers.
