The increased popularity in mobile devices and technology has motivated business to adopt the technology for increased productivity. However, not much research has investigated the adoption of mobile technology. The purpose of this thesis is to study the factors that influence the adoption of mobile technology and to develop a model of mobile technology adoption. The model can serve as a foundation for future research and provide useful guidelines for organizations that plan to adopting mobile technology. The model suggests two categories of factors that determine the decision of adopting mobile technology: fit and viability. Fit measures whether the functional capabilities of mobile technology match the need of a task, whereas viability measures whether an organization is ready for the technology. This research develops instruments for measuring fit and viability. A survey was conducted to collect data for model evaluation. Major findings from the study include: (1) the fitness between task and technology had a direct positive impact on the success of mobile system adoption. (2) Personal characteristic and organizational viability had indirect positive impacts on the success of mobile system adoption via the mediation of system quality. (3) Personal characteristic and organizational viability had positive impacts on the information quality and system quality but had no impact to the service quality. (4) Only the system quality had a positive impact on the success of mobile system adoption.

Internet of Things gör det möjligt att skapa “smarta miljöer” där information kan utbytas mellan olika typer av enheter. Denna teknik kan leda till effektivisering och automatisering på en mängd olika sätt, till exempel i våra hem och för affärsverksamheter. Ett område där intresset för denna teknik är stort är inom industrin, där området benämns som Industry 4.0. Där förväntas tekniken bland annat kunna användas för att effektivisera och förutse underhåll av maskiner, en inriktning som kallas e-maintenance. Denna nya teknik medför anpassning och utveckling av nya affärsmodeller och olika typer av informationssystem baserade på dessa. För att värde ska kunna skapas för verksamheter vid användande av en informationshanteringsplattform bör värdeskapande faktorer utforskas.   Syftet med denna studie är att undersöka, utifrån aspekter ur DeLone och McLeans (2003) Information System Success Model, hur värde kan skapas för ett fallföretag vid användning av en informationshanteringsplattform kopplad till sensorer i verksamheten genom Internet of things. Studien har genomförts med en abduktiv forskningsstrategi och en kvalitativ ansats. En fallstudie har genomförts på ett kundföretag till Sigma Technology, som studien görs i samarbete med. Utifrån ett urval av de anställda på fallföretaget har uppfattningar kring värdeskapande faktorer undersökts, genom enskilda semi- strukturerade intervjuer. Intervjuerna har analyserats och jämförts med Delone och McLeans (2003) Information Systems Success Model för att finna samband eller avvikelser.   I studien framkom det att de framstående variablerna för värdeskapande är enkelhet, informationsstruktur, tillgänglighet och pålitlighet. Dessa faktorer ansåg respondenterna vara särskilt viktiga vid utformning av en informationshanteringsplattform. Resultatet visar även att studien till stor del stämmer överens med det teoretiska ramverket och de beroendeförhållanden Information System Success Model presenterar. Faktorer som respondenterna inte ansåg vara lika betydande för värdeskapande och som därmed avvek från modellen är dimensionen servicekvalitet. Baserat på studiens resultat presenteras förslaget att vidareutveckla modellen med den nya dimensionen interaktionskvalité, eftersom att analysen av de värdeskapande faktorerna beskriver detta behov. / Internet of Things enables the creation of “smart environments”, where it is possible to exchange information between objects. This can lead to increased efficiency and automatization in different ways, for example in our homes and for business operations. An area where the interest for this technology is immense is in the industrial sector, and is referred to as Industry 4.0. For this area, the adoption of this technology is expected to, for example, improve efficiency and to predict maintenance, an approach known as e-maintenance. This new technology implies modification and development of business models and enables different types of information systems based on these. To be able to generate value for businesses when using an information management platform, variables that create value should be investigated.   The purpose of this study is to examine value-adding variables, with aspects from Delone & McLean’s Information System Success Model (2003), for a specific business case by using an information management platform through Internet of Things and sensors in their operations. This study has been carried out as a case study with one of Sigma Technology’s clients, which this study was made in collaboration with. This study was carried out with an abductive research approach and a qualitative method. To examine the opinions of the company’s employees, individual, semi-structured interview was conducted. The interviews was analyzed and compared with Delone & McLean's Information Systems Success Model, to identify resemblance or divergence.   The findings in this study show that the significant variables for value to be created are simplicity, information structure, accessibility and reliability. These factors are considered to be especially important, according to the respondents. Findings also show that the study is mostly consistent with the theoretical model, however, some variance has been discovered and some modifications of the model are presented. A dimension that the respondents did not consider equally important for value creation, and thus deviated from the theoretical framework, is service quality. Based on the significant factors presented in the study, the proposal is to further develop the model by adding an additional dimension, interaction quality, for the reason that the analysis of the value creating factors in this study describes this need.

Information technology (IT) plays an important role in contemporary organisations and this role continues to expand in scope and complexity and affects business operations dramatically. Advances in the IT industry have caused major changes in every industry sector. The banking industry is no exception and it has undergone a dramatic change over the past few decades. With the coming of the information age, IS investments are becoming increasingly important to banks` survival, growth and prosperity. IS managers are under increasing pressure to justify the value and contribution of IS expenditure to the productivity, quality and competitiveness of the organisation. This study aims to propose a model which investigates the success of information systems in the banking industry in order to help bank managers to evaluate the success of their IS, to be able to develop these systems and to improve the performance of bank managers and employees. Given that the ultimate dependent variable for this research is individual impacts, DeLone and McLean (2003) updated IS success model is leveraged and extended in this research. The study proposes a research model which is guided by the decision to select a suitable number of key potential demographic and situational variables, in addition to the adoption of DeLone and McLean (2003) updated model. This model proposes that a variety of factors were found to affect IS success in general, however, from the socio-technical viewpoint, IS success should capture both technological and human elements. Therefore, an effective Banking Information System (BIS) typically requires an appropriate combination of both. As such, Thus, the technological dimensions (i.e. system, service and information quality) and the human dimensions (e.g. user satisfaction, perceived system benefits, user involvement, user training, age, education and system use) can be a good starting point when considering suitable constructs for measuring BIS success. The research methodology of this study involved interviews with BIS practitioners and professionals to shape and refine the research model. Further, questionnaire survey was employed to collect data from bank managers in Egyptian banks. Structural Equation Modelling (SEM) using Partial Least Square (PLS) was used to test the research model. Three research models were proposed according to age groups and initial results from PLS analysis reported different results in each research model. Findings indicated that system, information and service quality, level of training, age, length of system use, user involvement and top management support were the main predictors (success constructs) of user satisfaction and individual impacts in the three proposed research models. However, the relationships between these constructs varied according to each age group of managers. The study offers important academic and practical contributions. Firstly, as a contribution to research, the study serves to extend the DeLone and McLean (2003) IS success model by introducing some key human and situational dimensions and confirming certain links in that model with the context of banking industry. The contribution to practice is especially relevant for bank CIOs, software designers and developers looking for ways to improve BIS developments by providing them with directions regarding the BIS success dimensions that should be considered to encourage bank managers to adopt and be more satisfied with BIS which in turn influence their job performance.

When measuring Information Systems (IS) success, it is important to know the type of IS being measured, the systems objectives, and the unit of analysis. As organizations invest in technology to help achieve strategic goals, they need to be able to measure IS success. Measuring the effectiveness of IS from an organizational perspective is the effect it has on achieving organizational goals. The effectiveness of information systems is a measure of net benefits. This empirical study investigated IS success in terms of the DeLone and McLean IS success model variable, net benefits. In order to measure IS success, the context of the investigation and the unit of analysis are as important as what is being measured. This investigation, in the context of a building automation system (BAS), evaluated the net benefits success measurement with the organization as the unit of analysis. Two hypothesis testing studies were conducted. The first study was a predictive investigation, which researched the relationship among the independent variables, kilowatt hours, kilowatt demand, and the dependent variable, the cost of energy. A multiple regression analysis was conducted to understand to what extent the independent variables could predict the dependent variable. The second study was a correlational investigation. This study was conducted to ascertain whether a building automation system affects the cost of energy. A Point Biserial Correlation Coefficient test was conducted to understand the relationship between the cost of energy and stores with a building automation system and those without. A t-test was conducted to understand the level of significance. The results of the analysis showed that the relationship between the cost of energy and a BAS is statistically significant and that the variables kilowatt hours and kilowatt demand are statistically significant as predictors of the cost of energy.

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.

Library automation in Ghana began barely 13 years ago with the University of Ghana Balme Library being the first to start automation in 2003. Library automation is attained by means of a specific type of information system, an integrated library system (ILS). Given that modern academic libraries rely heavily on their ILS to meet user needs, the success of the ILS is vital. In 1999 Farajpahlou published a set of 26 criteria to assess the success of ILS in university libraries that was subsequently validated in both developing and developed countries (Iran and Australia). In this case study of the University of Ghana Library System (UGLS) Farajpahlou‟s original set of criteria was assessed for applicability and used to assess the success of the UGLS by surveying 28 randomly selected library managers, IT specialists and selected paraprofessionals who work with the UGLS ILS. The study showed that, in the opinion of these respondents, the UGLS ILS conclusively satisfies 13 out of the 16 criteria accepted by the research respondents out of the 26 criteria that constitute the Farajpahlou (1999, 2002) success criteria. This outcome suggests that the UGLS ILS may not be conclusively deemed to be successful. Furthermore, the study also suggests that, although Farajpahlou‟s success criteria can serve as a basis for the assessment of ILS success in academic libraries, some criteria may need to be altered or removed and additional criteria added to make it a more robust set of criteria to assess ILS success globally. This research contributes to studies that seek to assess the success of library automation in academic libraries in Ghana and also contribute to the development of potentially suitable success assessment criteria, which may be of value to both researchers and practitioners.

A number of approaches of assessment associated with IS effectiveness have been examined, fundamental guidelines for research in this area have been derived, and a novel model of IS effectiveness has been proposed. A process based assessment method (PB-ISAM) based on the proposed effectiveness model has been elaborated. The new model and the new assessment method have been evaluated via three case studies. Specific implications have been drawn concerning the relationships between processes and the information system assessed. The three case studies have provided insight into the IS effectiveness field and for future work.

Since the introduction of computers in to organisations in the 1950s, computer information systems have become powerful organisational instruments. The uptake of information technology including information systems (IS) and the impact of these technologies have been phenomenal, particularly in the least developed countries (LDCs). Organisations in these countries have continued to utilise IS as a development tool with the belief that it will enhance business processes, in many instances accelerated by foreign assistance. IS can have a positive effect on users, organisations and national development, measured economically or otherwise at the individual, organisational, and national levels. Yet IS implementation and the measure of its success is characterised by a high rate of failure and disagreement among scholars and practitioners. The success of organisational IS is influenced by a fabric of many variables, including contextual elements. In this regard IS can be influenced by both the organisational context in terms of strategies, structures, politics and culture, and by the wider political socio-economic, cultural, and technological climate within which organisations exist. Understanding the contributing variables and the barriers that impede IS success, would better prepare organisations to overcome the inherent difficulties. There is a large body of work documenting the usefulness and consequences of IS. However, these studies have been concentrated in the developed countries (DCs), hence, little is known about IS implementation in LDCs. DCs and LDCs differ in their contextual and social settings, and a uniform analysis may not be applicable in their disparate settings. Indeed the paucity of research and data in the IS domain indicates that the study would benefit an LDC such as Papua New Guinea (PNG) and contribute to knowledge in understanding IS implementation in an LDC environment. This thesis reports on a study that examined IS implementation success in PNG organisations in the context of an LDC. Computers were introduced to PNG in the 1960s, however, no studies have been undertaken to date in this domain that the author is aware of. Hence, the objective of this study was to provide detailed analysis of IS, the context in which it was implemented, its interaction with organisational and external settings, and elicit the underlying elements associated with its success. It also explores the emphasis placed on each of the elements and the extent to which organisations effectively addressed these elements to ensure IS success. The exploratory study employs a multi method design - beginning in Stage 1 with case studies, followed by a survey in Stage 2. Stage 1 adopted a multiple case study approach. Eight case studies were undertaken, however, results of only four case studies are reported in this thesis. Data obtained in the case studies provide a useful basis for the survey. The study in Stage 2 consolidated and expanded on the case study findings from the perspective of a wider population. All the organisations contacted but not involved in the Stage 1 study contributed by participating in the survey. The study identified more than fifty elements that contributed to the success of IS in PNG organisations. There were significant similarities to the findings of studies in other DCs and LDCs despite the disparate contextual conditions. Several elements, not identified in prior studies, were also revealed. Based on this study, a set of principles pertaining to IS implementation and management in PNG were postulated. Similarly a set of recommendations were also outlined.

Recent advances in information technologies and subsequent explosive growth of computer software use in practically all aspects of everyday life provide tremendous opportunities and benefits for improving people's lives. However, significant proportion of software projects represents cancelled, abandoned or otherwise failed projects. This situation exists not only in commercial software products or government information systems, but also in an increasingly popular and important domain of free/libre and open source software (FLOSS). The problem of failures in software development projects requires identification and understanding of the factors of success and their interrelationships. Practice and previous research suggest that governance of software development projects plays crucial role in their success. Increasing adoption and sponsorship of FLOSS by commercial firms and government organizations present additional challenges; such sponsorship may also interact with governance in FLOSS projects and play a role in determining their success. This dissertation focused on analyzing the role and significance of governance and organizational sponsorship in the success of FLOSS development. This study used both conceptual analysis and empirical methods. The conceptual analysis phase, a preliminary study based on the review of existing literature, produced a partial model of success in FLOSS development. This model was verified in an empirical phase, which statistically analyzed data from multiple FLOSS repositories and other public sources. The statistical analysis was based on structural equation modeling (SEM) approach. Results of this study did not confirm hypothesized effects of the main two factors (governance and organizational sponsorship) on FLOSS success, but confirmed a positive effect of project maturity on the success. The likely reason of the lack of support for the main factors is unavailability of sufficient and correct data for proper operationalization. This and other uncovered issues are planned to be addressed in the future research on the topic, for which this dissertation formed a solid conceptual and data analysis framework.
