Business intelligence is an effort to better understanding of company processes and business consequences in which company occur. The main goal of this thesis is to characterize the principles and possibilities of implementation and application Business intelligence in small or medium enterprise. This goal should be achieved by description of general needs which small or medium enterprise, looking forward to use business intelligence, has. This includes evaluation and universal description of information technologies in small and medium enterprises, as well as what data are used for managerial decisions and how are they made. In order to implement BI into the small or medium enterprise, it is necessary to imply how the Business intelligence work and on what principles. The application part of this thesis describes real procedures in preparation of BI implementation, impact on company and evaluation of the meaningfulness of this solution.

<p>När en organisation väljer att implementera ett affärssystem, leder det till en stor teknologisk förändring, men även en stor organisationsförändring. Det faller sig då naturligt att implementeringen kommer att ge intryck på organisationens övriga verksamhet. Uppsatsen redogör för om och hur de anställda i en organisation, som implementerat ett affärssystem, upplever förändring i sina arbetsroller samt i organisationens styrning. Arbetsroller inkluderar både de anställdas arbetsuppgifter samt deras relationer till kollegor. En fallstudie har gjorts på Lantmännen Cerealia Uppsala, där detta undersökts ur ett lednings- och avdelningsperspektiv. Till hjälp för att utreda om och hur förändring skett användes till insamlandet av det empiriska materialet, främst besöksintervjuer och en deltagande observation på den studerade avdelningen. Slutsatsen blev att alla de anställda upplevde en markant skillnad i arbetsuppgifterna, en viss förändring i relationer till andra anställda medan styrningen upplevdes som oförändrad. Studien utvisar att det finns olika starka samband mellan dessa faktorer, och/eller att förändringar i faktorerna tar olika lång tid.</p> / <p>When an organization chooses to implement an Enterprise Resource Planning (ERP) system it leads to a major technological change as well as to a major organizational change.

This thesis aims to answer if and how the employees of an organization, which has implemented an ERP system, are experiencing changes in their work roles, in terms of both their formal duties and their relationships to colleagues, as well as in the organization's management. In order to do so, a case study of the company of Lantmännen Cerealia Uppsala, in which both management and divisional perspectives were studied, was done. The case study entailed personal interviews as its central methodological choice, but also incorporated participant observations of the studied division. The conclusion is, that all employees experienced a significant change in their formal duties, a slight change in their relationships to colleagues and that the organization’s management remained unaffected. This study shows that there exist a variety of strong correlations between these variables, and that changes within these factors take varying amounts of time to occur.</p>

Altos investimentos são feitos na área de tecnologia da informação (TI), especialmente em sistemas de gestão empresarial (ERP). Entretanto, tais investimentos não garantem o sucesso do sistema. Estudos indicam que o sucesso de um sistema de informação pode ser avaliado através da satisfação dos usuários do sistema. O tema deste estudo é a satisfação do usuário final e do usuário-chave de um sistema de gestão empresarial (ERP) como forma de avaliar o sucesso do sistema. O objetivo da pesquisa é medir a satisfação dos usuários do sistema. O método utilizado é a pesquisa Survey, realizada a partir da combinação de dois modelos apresentados pela literatura, um para o usuário final e o outro para o usuário-chave. A pesquisa foi realizada em duas etapas: o estudo piloto e a pesquisa final. O processo de validação e refinamento do instrumento utilizou diferentes técnicas, como: Validade de Face e Conteúdo, Análise de Confiabilidade (Coeficiente Alfa de Cronbach), Análise de Item Total Corrigido (CITC), Análise Fatorial Exploratória Convergente (Teste de Unidimensionalidade) e Discriminante. Foi verificado que as variáveis Acuracidade e Confiabilidade se agruparam em uma única variável (Exatidão). As demais variáveis permaneceram iguais e nenhum item precisou ser excluído. Através da Análise de Regressão, foi possível constatar que existe uma relação entre as variáveis 'Percepção de Sucesso do Sistema’ e ‘Satisfação com o Sistema’. A principal contribuição desta pesquisa tanto para a prática gerencial como para o meio acadêmico e empresarial é a validação de um instrumento de pesquisa adaptado para a realidade brasileira, capaz de medir a satisfação do usuário de um sistema de gestão empresarial (ERP), através da percepção dos usuários do sistema. / Large investments are made in Information Technology (IT), specially in Enterprise Resource Planning Systems (ERP). But such investments are not a success guarantee. Previous researches show that the Information System (IS) success might be evaluated by determining the system users’ satisfaction. The subject of this paper is the ERP end-users’ and key-users’ satisfaction as a mean to evaluate ERP success. The purpose of this research is to measure ERP users’ satisfaction. The method used is a survey, which was based on a combination of two previous models, one about end-users’ and the other about key-users’ satisfaction. The survey was conducted in two steps: pre-test study and final study. The instrument was validated and refined through the use of qualitative and quantitative procedures such as face and content validity, reliability analysis (Cronbach Alfa), corrected item total correlation (CITC), exploratory factor analysis within and among blocks. As a result, the variables Accuracy and Reliability merged into a new variable (Exactness). All other variables remained the same, and none had to be excluded. Through the Regression Analysis it was possible to verify that there is a relationship between ‘System Perceived Success’ and ‘System Satisfaction’. The main academic and managerial contribution of this paper is a research instrument, duly validated and adapted to Brazilian reality, to measure ERP users’ satisfaction.

We address the task of mapping a given domain model (e.g., an industry-standard reference model) for a given domain (e.g., ERP), with the source code of an independently developed application in the same domain. This has applications in improving the understandability of an existing application, migrating it to a more flexible architecture, or integrating it with other related applications. We build on a previous approach, which uses relationships among source code elements for improving the precision of the mapping process. We extend this approach by considering relationships among domain model elements in addition to relationships among source code elements, and also by stating the mapping process as an optimization problem. We have implemented our approach, and compared it with the previous approach. We show that our approach gives significantly better precision as well as recall than the previous approach when applied on a real industry-standard domain model and an open-source application.

The global business environment has changed dramatically in recent years, as competition in complex knowledge-based economies has increased. Enterprise Resource Planning (ERP) systems have been viewed as a way to manage increased business complexity, leading to the rapid adoption and implementation of such systems, as ERP can support enterprises to improve their competitiveness. Knowledge management (KM) is crucial for ERP systems implementation, however a highly demanding task. Therefore, the primary concern of this research is to examine the effectiveness of knowledge management activities that would contribute to achieve ERP implementation success. This study adopted mixed methods approach by combining semi-structured interviews and a questionnaire to collect empirical data from ERP professionals in both manufacturing and service sector organisations. In the qualitative phase, it develops the “framework of integrative knowledge” based on empirical evidence, that can improve KM competence for ERP implementation success. Data analysis has been undertaken using a combination of thematic analysis and comparative analysis with respect to 14 ERP implementations in the UK. The framework integrates multiple perspectives in terms of knowledge components to enhance KM competence, including knowledge types, knowledge layers, KM lifecycle and knowledge determinants. It discovered 19 knowledge determinants to drive knowledge management activities during ERP projects, which is another vital contribution to the existing knowledge. Furthermore, the study develops the “knowledge network model” for ERP implementations in order to facilitate the knowledge flows between various stakeholders involved in ERP implementations, which can help to understand the interactions between the knowledge components. Moreover, sub-knowledge types (knowledge elements) under each knowledge type were discovered through empirical evidence. The quantitative phase was adopted to extend the findings of the qualitative phase. The knowledge types and knowledge elements were prioritised using Analytic Hierarchy Process (AHP) method through an online AHP based questionnaire with 77 responses from ERP professionals involved in UK ERP implementations. Furthermore, knowledge prioritisation demonstrates how effectively the framework of integrative knowledge can be used during ERP implementations with the help of prioritised knowledge. In total 4 knowledge types and 21 knowledge elements were ranked based on their contribution to achieve ERP success; four variables of information quality, systems quality, individual impact and organisational impact were used to measure ERP success. This study has number of theoretical contributions including framework of integrative knowledge, knowledge network model for ERP implementations and ERP knowledge prioritisation. Moreover, the framework of integrative knowledge can provide ERP practitioners with useful guidance on what the key knowledge determinants are and how the relationships between knowledge components should be best managed to achieve ERP implementation success in business reality.

There have been numerous studies on formal methods but little utilisation of formal methods in the commercial world. This can be attributed to many factors, such as that few specialists know how to use formal methods. Moreover, the use of mathematical notation leads to the perception that formal methods are difficult. Formal methods can be described as system design methods by which complex computer systems are built using mathematical notation and logic. Formal methods have been used in the software development world since 1940, that is to say, from the earliest stage of computer development. To date, there has been a slow adoption of formal methods, which are mostly used for mission-critical projects in, for example, the military and the aviation industry. Researchers worldwide are conducting studies on formal methods, but the research mostly deals with path planning and control and not the runtime verification of autonomous systems. The main focus of this dissertation is the question of how to increase the pace at which formal methods are adopted in the business or commercial world. As part of this dissertation, a framework was developed to facilitate the use of formal methods in the commercial world. The framework mainly focuses on education, support tools, buy-in and remuneration. The framework was validated using a case study to illustrate its practicality. This dissertation also focuses on different types of formal methods and how they are used, as well as the link between formal methods and other software development techniques. An ERP system specification is presented in both natural language (informal) and formal notation, which demonstrates how a formal specification can be derived from an informal specification using the enhanced established strategy for constructing a Z specification as a guideline. Success stories of companies that are applying formal methods in the commercial world are also presented. / School of Computing
