The concept of Architecture has received widespread acceptance within the construction industry. However, its importance within the Information Technology industry is a contested one. Critics of Architecture in the Information Technology (IT) industry posit that there is inadequate evidence to assume that it makes a difference to performance of IT. Enterprises increasingly need to ensure that they leverage their IT benefits not only within their silos but across business units. This need has driven ideas to introduce enterprise-wide blueprints or Enterprise Architecture (EA) Planning solutions to guide them in the design and implementation of IT. This study uses a quantitative survey to attempt to answer two questions: 1) What factors influence EA Planning within organizations? 2) To what extent does EA Planning improve IT performance? The Diffusion of Innovation theory (Compatibility, Ease of Use and Relative Advantage) was used to investigate the use of EA Planning whilst the Resource Based View of the Firm was used to investigate the performance impact of EA Planning. IT Performance is measured by Heterogeneity of Physical IT Infrastructure, Replication of IT Infrastructure Services, Business Application Integration and Enterprise Data Integration. EA Planning is measured by EA Planning Human Capital, IT Infrastructure Flexibility and Partnership Quality. Data was collected from 90 architects, some from South African consulting companies and the rest from architects around the world linked to popular Enterprise Architecture virtual communities. The key findings were significant relationships between the following for the factors that influence use of EA Planning: Compatibility and IT Infrastructure Flexibility; Ease of Use of EA Planning Policies and EA Planning Human Capital; Relative Advantage and EA Planning Partnership Quality. Significant relationships were found between the following for factors that influence IT Performance: EA Planning Human Capital and IT Performance (a combination of Enterprise Data Integration, Business Application Integration, Replication of IT Infrastructure Service and Heterogeneity of Physical IT Infrastructure); EA Planning IT Infrastructure Flexibility and Heterogeneity of Physical IT Infrastructure; EA Planning IT Infrastructure Flexibility and Business Application Integration. EA Planning Partnership Quality was rejected as a determinant of IT Performance. This study sheds light on how resistance to EA Planning can be reduced and also highlights the potential benefits of EA Planning in organizations. The implications will directly affect the relationship between EA practitioners and IT projects.

This research intends to investigate the relationships among governance environment, organizational structure, information technology governance, information technology use, and information technology performance. An empirical study was conducted to collect from Taiwanese companies. The result shows three major findings. First, small positive effect exists between information technology use and the alignment between governance environment and organization structure. Second, information technology use has positive effects on information technology performance. Finally, the relative governance of IT department does not affect IT use. This research helps organizations understand how information technology governance affects IT use and performance. Organizations could adjust their organization governance strategy to fir its structural and cultural environment in order to improve information technology performance.

In last decades, we are viewers of the trend, when business informatics adopts and implements general managerial methodology, methods and tools. These are modified in the specific condition of business informatics. We can demonstrate this trend on the follow examples: Corporate Governance, derived IT Governance. Corporate Performance Measurement (CPM), derived IT Performance Measurement (IT PM) or Balanced Scorecard (BSC), derived IT Balanced Scorecard (IT BSC). There is enough scope for all this domains in the Czech written literature. But there is no scope for IT controlling. The main goal of this thesis is verify the Eschenbach concept of controlling can be adopted by business informatics in its specific condition. This diploma thesis also handles about problems and benefits caused by implementation this concept of controlling in business informatics. The main goal is reached by exploration literature, researches, case studies, articles and other paper or electronic essays, when the methods of deduction and synthesis are used for customizing general facts about controlling for IT Governance and IT Management Thesis is divided in three parts: At the beginning of this diploma thesis, there are introduced right assumptions for correct understanding of IT controlling. The benefits of this part we can see in the defining of system attributes of business informatics and comparison IT Management and IT Governance with two theoretical approaches to management control system. By this comparison is verified the possibility to adopt controlling in business informatics. In the second part of this diploma thesis, there is description of author concept IT controlling based on Eschenbach. There is description of main IT controlling function, institutionalization of IT controlling and the role of IT controller in organizational structure. The rest of this thesis is devoted to the concrete IT controlling functions, problems and solving of theirs. These are divides in two categories. The firs one is focused on performance oriented IT controlling. The second one is focused on IT costs oriented IT controlling. This thesis handles about IT controlling complexly. The result of this diploma thesis is author concept of IT controlling based on Eschenbach concept of controlling.

The topic of this master thesis are the Systems for managing enterprise IT. This paper is divided into three parts, where the first and second part gives a comprehensive view and concentrates existing knowledge from the examined area. The third part consists of my own conclusions based on available resources. For the overall IT Management, it is necessary to manage and measure IT Performance. Therefore, the first part deals with IT Performance Management (ITPM).Performance Management should penetrate the entire organization and ITPM should be part of the overall Performance Management of the organization. It is necessary to manage and measure performance at all levels of the organization (strategic, tactical and operational level). To measure the organizational IT performance, it is necessary to design relevant metrics. To design these metrics it is recommendable to follow a framework, whether ITIL or COBIT. The second part of this paper deals with IT Management frameworks and their support for designing metrics. It deals with the new wave in IT -- ITSM (IT Service Management). The de facto standard for ITSM is ITIL. Furthermore, the second part discusses the de facto standard for IT Governance -- COBIT and IT Balanced Scorecard for clarifying and translating the vision and strategy into specific objectives. The third part describes a specific procedure for designing metrics according to the ITIL framework. In addition, this part describes the software Metricus which enables a centralized management of ITPM and uses a holistic view of the overall ITPM.

Purpose – Motivated by the increasing role of information technology (IT) in today’s organizations, the purpose of this paper is to examine the relationships between business and IT executives in order to improve the organizational performance of the different aspects of IT technology and related systems. In the process, special attention is given to drivers which facilitate the cooperation between the parties involved. Design/methodology/approach – This survey-based research utilizes structural equation modeling methodology to uncover the relevant variables pertaining to the promotion of a positive social and strategic context needed to increase the effectiveness of organizational IT facets. Findings – The effectiveness of IT in modern organizations is contingent on a social alignment, business – IT alignment, strategic consistency, and common vision among the people who manage the IT function and those who need the organization. Research limitations/implications – This study is based on a sample of Portuguese manufacturing organizations. Therefore, findings and conclusions should be interpreted accordingly. In this context, future research in other organizational cultural settings is called for in order to refine and validate the results of this study. Practical implications – The role of establishing an organizational culture which stresses the common goal and mutual trust and cooperation in creating effective IT organizational utilization is underscored. As such, business executives are encouraged to exercise their leadership skills in order to create an organizational strategy which aligns IT capabilities and investments with the competitive strategy of the organization. In this context, creating an organizational culture which promotes business – IT alignment in a healthy social context is necessary. Originality/value – The issues and concerns addressed in this study should bridge the gap between business and IT executives. In the process, this study facilitates and encourages the effective utilization of the different facets of IT technology as they better serve the people of the organization. This advances the cost and practice of the strategic organizational role of IT investments.

[ES] La presente tesis doctoral desarrolla un modelo para diagnosticar que valor puede aportar la infraestructura de tecnologías de la información a las empresas. Su objetivo principal es ofrecer herramientas que ayuden a mejorar la toma de decisiones sobre la inversión y explotación de tecnologías de la información, considerando sobre todo el impacto qu tienen en la generación de valor. Para ello, se basa en el análisis de diversos autores clave en la materia y en la aplicación del modelo propuesto en el sector Textil-Hogar de la Comunidad Valenciana. El modelo teórico planteado se construye sobre la idea de que la infraestructura de tecnologías de la información debe evaluarse en función del esfuerzo realizado por las empresas en cada una de las actividades de la cadena de valor de Porter. Posteriormente, se realiza una comparación, combinando técnicas de análisis cuantitativo y cualitativo, con datos obtenidos a partir de encuestas y bases de datos. A través de este proceso, se examinan hipótesis como la existencia de una relación entre la inversión en tecnologías de la información y la capacidad de creación de valor de la empresa, así como el impacto de dirigir estos esfuerzos hacia actividades críticas dentro de su sector. Los resultados de la investigación muestran que las empresas que gestionan estratégicamente su infraestructura tecnológica pueden mejorar su competitividad y generar un mayor valor. Se destaca la importancia de una adecuada planificación y asignación de recursos, ya que no toda inversión en tecnologías de la información garantiza automáticamente una mejora en el rendimiento empresarial. La tesis concluye que la combinación de metodologías cualitativas y cuantitativas permite obtener una visión más precisa del papel de la I en la creación de valor y ofrece un marco de referencia útil para la toma de decisiones en este ámbito. / [EN] This thesis develops a model for diagnosing the value contribution of Information Technology (IT) infrastructure in companies. Its main objective is to provide tools that help improve decision-making regarding IT investment and utilization, considering its impact on value creation. To achieve this, the research builds on the analysis of key authors in the field and applies the proposed model to the Home Textile sector in the Valencian Community. The theoretical model is based on the idea that IT infrastructure should be evaluated according to the effort made by companies in each of the activities within Porter’s value chain. An empirical validation is then carried out using a combination of quantitative and qualitative analysis techniques, with data obtained from surveys and databases. Through this process, hypotheses are examined, such as the existence of a relationship between IT investment and a company's value creation capacity, as well as the impact of directing these efforts toward critical activities within its sector. The research results show that companies that strategically manage their IT infrastructure can enhance their competitiveness and generate greater value. However, the study emphasizes the importance of proper planning and resource allocation, as not all IT investments automatically lead to improved business performance. The thesis concludes that combining qualitative and quantitative methodologies provides a more accurate view of IT’s role in value creation and offers a useful framework for decision-making in this field. / Miñana Terol, JL.
