    Indicators predicting similarities in maturity between processes: An empirical Analysis with 35 European organizations2009Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Compliance audits and IT process evaluations are time-demanding to conduct and methods to simplify and support such evaluations are valuable. This article proposes a set of indicators that can be used to predict similarities in IT process maturity and thereby be used to optimize resource allocations when conducting process maturity evaluations and compliance audits. The indicators have been identified from the COBIT framework and tested against process maturity data from 35 European organizations. Four out of six proposed indicators were supported in the statistical analysis. These indicators can be used as an instrument in COBIT-based maturity evaluations and compliance audits to make the assessment process more resource-efficient.

    An IT management assessment framework: Evaluating enterprise architecture scenarios2007Inngår i: Information Systems and E-Business Management, ISSN 1617-9846, E-ISSN 1617-9854, Vol. 5, nr 4, s. 415-435Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Enterprise architecture, EA, is an established approach for the model-based and holistic management of IT. The scope of EA is however wide and the predominant EA frameworks suggest the creation of broad and detailed models. IT management cannot control all areas spanned by the present frameworks for EA models. In order to ensure well-informed decisions, IT management has a series of questions that need to be answered. This paper proposes an assessment framework that can be used to identify relevant questions for assessments of EA and EA scenarios, within the areas of EA that IT management can control. Three top dimensions in the proposed framework are presented: IT organization, IT systems, and Business organization. The framework further includes sub dimensions for identifying questions. An application of the assessment framework, as it was applied to assess EA scenarios in a power company, is also described.

    Enterprise architecture analysis with extended influence diagrams2007Inngår i: Information Systems Frontiers, ISSN 1387-3326, E-ISSN 1572-9419, Vol. 9, nr 2-3, s. 163-180Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The discipline of enterprise architecture advocates the use of models to support decision-making on enterprise-wide information system issues. In order to provide such support, enterprise architecture models should be amenable to analyses of various properties, as e.g. the level of enterprise information security. This paper proposes the use of a formal language to support such analysis. Such a language needs to be able to represent causal relations between, and definitions of, various concepts as well as uncertainty with respect to both concepts and relations. To support decision making properly, the language must also allow the representation of goals and decision alternatives. This paper evaluates a number of languages with respect to these requirements, and selects influence diagrams for further consideration. The influence diagrams are then extended to fully satisfy the requirements. The syntax and semantics of the extended influence diagrams are detailed in the paper, and their use is demonstrated in an example.

    Extended Influence Diagrams for System Quality Analysis2007Inngår i: Journal of Software, ISSN 1796-217X, Vol. 2, nr 3, s. 30-42Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Making major changes in enterprise information systems, such as large IT-investments, often have a significant impact on business operations. Moreover, when deliberating which IT-changes to make, the consequences of choosing a certain scenario may be difficult to grasp. One way to ascertain the quality of IT investment decisions is through the use of methods from decision theory. This paper proposes the use of one such method to facilitate IT-investment decision making, viz. extended influence diagrams. An extended influence diagram is a tool able to completely describe and analyse a decision situation. The applicability of extended influence diagrams is demonstrated at the end of the paper by using an extended influence diagram in combination with the ISO/IEC 9126 software quality characteristics and metrics as means to assist a decision maker in a decision regarding an IT-investment.

    A survey on CIO concerns - do enterprise architecture frameworks support them?2006Inngår i: Information Systems Frontiers, ISSN 1387-3326, E-ISSN 1572-9419, Vol. 8, nr 2, s. 81-90Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The challenge of IT management is today considerable. In industry, the organizational role of the Chief Information Officer (CIO) has been promoted as the owner of these challenges. In spite of a general acceptance of the problems associated with the responsibilities of the CIO, very little academic research has been conducted on the issues and constraints of this role. In order to address these shortcomings, this article presents the results of a survey in which Swedish CIOs have prioritized their most important concerns. In academia, a response to the IT system management challenges has presented itself in the discipline of Enterprise Architecture. The article argues that the CIO role is the primary stakeholder of Enterprise Architecture, so his/her need for decision support should guide Enterprise Architecture research and framework development. Therefore, the article presents a brief review over how well two existing Enterprise Architecture frameworks address the surveyed concerns of the CIO. Results from the survey indicate that the three highest prioritized concerns of CIOs are to decrease the cost related to the business organization, to improve the quality of the interplay between the IT organization and the business organization and to provide new computer-aided support to the business organization. The comparison between the CIOs' prioritization and the foci of the frameworks shows some discrepancies. The largest disharmony lies in the lack of decision support for issues related to the IT organization. Furthermore, support for explicitly estimating and managing costs is lacking within the frameworks.

    A Reference Model for IT Management Responsibilities2006Inngår i: Proceedings - 2006 10th IEEE International Enterprise Distributed Object Computing Conference Workshops, EDOCW2006, 2006, s. nr. 4031286-Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This reference model for IT management responsibilities covers the most important aspects when modeling, analyzing and evaluating enterprise architecture, EA. The reference model can be employed to support IT management in their quest to make well-informed decisions, e.g. to derive architectural principles in order to obtain a proper scope for EA activities, measure the status of the current EA, follow up changes committed, and evaluate alternative EA scenarios. The model is based on extensive literature studies and has been tested in a series of empirical studies

    Predicting IT Governance Performance: A Method for Model-Based Decision Making2008Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Contemporary enterprises are largely dependent on Information Technology (IT), which makes decision making on IT matters important. There are numerous issues that confuse IT decision making, including contradictive business needs, financial constraints, lack of communication between business and IT stakeholders and difficulty in understanding the often heterogeneous and integrated IT systems. The discipline of IT governance aims at providing the decision making structures, processes, and relational mechanisms, needed in order for IT to support and perpetuate the business. The adjacent discipline of enterprise architecture provides a broad range of frameworks and tools for model-based management of IT. Enterprise architecture is a commonly and successfully used approach, but the frameworks need to be adapted with respect to the concerns at stake in order to become truly useful.

    The IT organization includes all people involved in decision making regarding IT. The quality of the IT organization differs between enterprises and depends on aspects such as: are rights and responsibilities assigned to the appropriate people, are formalized processes implemented, and does proper documentation exist? This internal IT organization efficiency is labeled IT governance maturity. One might argue that internal efficiency metrics of the IT organization are of moderate interest only. What really matters is the external effectiveness of services that the IT organization delivers to the business. This latter effectiveness is labeled IT governance performance. Even though it is reasonable to believe that enterprises with good IT governance maturity also achieve high IT governance performance, the validity of this assumption has never been tested. IT management’s ability to make well-informed decisions regarding internal IT organization matters would increase if it were possible to predict IT governance performance.

    The contribution of this thesis is a method for model-based IT governance decision making. The method includes a metamodel, i.e. a modeling language, and a framework for the assessment of IT governance maturity and performance. The method also allows prediction of IT governance performance. 

    This thesis is a composite thesis consisting of four papers and an introduction. Paper A presents an overview of the method for model-based IT governance decision making. Paper B presents the mathematical foundation of the prediction apparatus, i.e. a Bayesian network that is based on statistical data. Paper C presents how the method can be used in practice to support IT governance decision making. Finally, Paper D analyzes the correlation of IT governance maturity and performance. The analysis is based on statistical data from case studies in 35 organizations.

    Getting the Priorities Right: Literature vs Practice on IT Governance2006Inngår i: Technology Managment for the Global Future, 2006: PICMET 2006, 2006, s. 18-26Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The field of IT governance has emerged in order to address organizational issues for IT value delivery to the business. However, a shared view of the definition of IT governance is lacking between researchers and practitioners, and support for decision-making is neither present. A commonly agreed upon definition of IT governance would be useful but has until today not been available. This article presents an IT governance definition based on an extensive literature study. IT governance is the preparation for, making of and implementation of IT-related decisions regarding goals, processes, people and technology on a tactical or strategic level. The components of the definition are prioritized in two different ways. A theoretical prioritization was made to highlight the most important concerns according to 60 different publications. Another prioritization was carried out with a group of Swedish IT governance experts. The opinions of practitioners and literature did mostly align, but differences were identified in the importance of understanding the situation at hand prior to making decisions, and monitoring of the decisions' impacts

    Assessement of IT governance: A prioritization of cobit2006Inngår i: Proceedings of the Conference on Systems Engineering Research, Studentlitteratur, 2006Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    A shared view on the definition of IT governance is lacking and practitioners do not use present IT governance frameworks to support their decision-making. A commonly agreed upon definition of IT governance would be very useful and would serve the development and refinement of IT governance frameworks and assessment methodologies. This article presents an Architecture Theory Diagram, ATD, and a framework for defining IT governance based on an extensive literature study. IT governance is the preparation for, making of and implementation of IT-related decisions regarding goals, processes, people and technology on a tactical or strategic level. The framework for defining IT governance was used to compare how IT governance is defined in literature, and within a group of IT governance experts. Cobit is the most well-known framework for IT governance and it is frequently used by practitioners. While comparing Cobit?s definition of IT governance to the previously identified concerns of literature and practitioners, it showed that Cobit does support most needs, but lacks in providing information on how decisionmaking structures should be implemented.

    The IT Organization Modeling and Assessment Tool: Correlating IT Governance Maturity with the Effect of IT2008Inngår i: Proceedings of the 41st Hawaii International Conference on System Sciences, 2008Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Does good IT governance improve the effect of IT? This paper presents the IT Organization Modeling and Assessment Tool (ITOMAT) which has been created to overcome operationalization and subjectivity weaknesses in the Control Objectives for Information and related Technology (COBIT) framework. ITO-MAT was applied to assess IT governance maturity in four case studies. Simultaneously, external metrics of the effect of IT were collected and correlated to the maturity levels. Based on the correlations, a model linking internal and external measures was created. The model can be used to predict the effect of IT given the maturity levels of IT processes.

    IT Governance Decision Support using the IT Organization Modeling and Assessment Tool2008Inngår i: 2008 Portland International Center for Management of Engineering and Technology, Technology Management for a Sustainable Economy, PICMET '08, New York: IEEE , 2008, s. 802-810Konferansepaper (Fagfellevurdert)
    Abstract [en]

    It is important to ensure that the IT governance is not only designed to achieve internal efficiency in the IT organization, such as deploying good IT processes and making sure that the means and goals are docu-mented. The final goal of good IT governance is rather to provide the business with the support needed in order to conduct business in a good manner. This paper describes the IT Organization Modeling and As-sessment Tool (ITOMAT) and how it can be used for IT governance decision making. ITOMAT consists of an enterprise architecture metamodel that describes IT organizations. ITOMAT further contains a Bayesian network for making predictions on how changes to IT organization models will affect the IT governance performance as perceived by business stakeholders. In order to make such predictions accurately, the network learns from data on previous experience. Thorough case studies at 20 different companies have been conducted in order to calibrate the network. Finally, the paper describes a case study where ITOMAT was used to analyze the future impact of two IT organization change scenarios in a medium sized engineer-ing company.

    The Effect of IT Governance Maturity on IT Governance Performance2010Inngår i: Information systems management, ISSN 1058-0530, E-ISSN 1934-8703, Vol. 27, nr 1, s. 10-24Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    There are several best practice based frameworks that detail effective arrangements for the internal structure of an IT organization. Although it is reasonable that there is a correlation between the quality of the internal structure of an IT organization - labeled IT governance maturity, and the external impact of the same IT organization on the business - labeled IT governance performance, this has not been validated. The results, based on 35 case studies, confirm the hypotheses of a positive correlation between IT governance maturity and IT governance performance. Among IT processes described in 34 references, the internal structure of the IT organization, clearly defined organizational structures and relationships, mature quality management, and cost allocation show the strongest positive correlation to IT governance performance. The maturity of project management and service level management, as well as performance and capacity management, show almost no correlation to IT governance performance. The findings can be used to improve current frameworks for IT governance.

ITOMAT further contains a Bayesian network for making predictions on how changes to IT organization models will affect the IT governance performance as perceived by business stakeholders. In order to make such predictions accurately, the network teams from data on previous experience. Case studies at 35 companies have been utilized for calibration of the network.

    Modeling and Evaluating the Maturity of IT Governance2008Inngår i: Proceedings of the International Council on Large Electrical Systems, CIGRÉ, 2008, s. 8p-Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The enterprise-wide Information Technology (IT) platform at transmission network owners and electric utilities has normally been gradually developed for a long period of time. Each business unit within these companies have, unfortunately often independently, developed and acquired the IT systems needed. The IT platform is therefore normally composed of a considerable number of components, storing redundant data and implementing similar functionality. In the re-regulated power industry, the need for management of IT is made important by the frequent changes in the business environment, such as mergers, acquisitions, and new market rules. IT governance denotes how the IT organization is managed and structured and provides mechanisms that enable the development of integrated business and IT plans, allocation of responsibilities within the IT organization, and prioritization of IT initiatives. It is important to ensure that IT governance is designed not only to achieve internal efficiency in the IT organization, such as deploying good IT processes. The final goal of good IT governance is rather to provide the business with the support needed in order to conduct business in a good manner. Of particular interest is the impact on business performance that a well governed IT organization can have. The Control Objectives for Information and related Technology (CobiT) framework provides the most relevant and detailed support for IT governance processes, activities, roles, documents and metrics available. CobiT?s entities are mainly of desccriptive nature and propose how the IT organization should be structured according to best practice. Another inherent weakness is that CobiT focuses on entities inherent to the IT organization and do not address the external effectiveness of the IT organization. This article desccribes the IT Organization Modeling and Assessment Tool (ITOMAT) which is an IT governance decision support tool. It relies partly on the CobiT framework for internal maturity assessments of the IT organization and is also enhanced with information about statistical correlations to external IT governance performance metrics. This means that the ITOMAT is able to statistically predict external business effectiveness of suggested IT organization scenarios. The paper also presents an example in which ITOMAT is used to predict IT governance performance. The paper ends with discussion, conclusions and references.

    Model-based it governance maturity assessments with cobit2007Inngår i: Proceedings of the 15th European Conference on Information Systems, ECIS 2007, 2007, s. 1276-1287Konferansepaper (Fagfellevurdert)
    Abstract [en]

    IT governance is an executive level concern in many enterprises today, but a method for credible, reliable, and cost-efficient IT governance maturity assessment has been lacking. Control Objectives for Information and related Technology (Cobit) is best practice in the area, but the method requires an experienced analyst to perform the assessment and the provided analysis framework is vague and ambiguous. This paper presents a Cobit based method designed to overcome these featured problems. It comprises a modeling language for IT governance based on Cobit, and a transparent analysis framework which enables aggregation of single metrics into comprehensive maturity scores. The applicability was tested in a small case study. Results demonstrate that the method can be used to conduct time-efficient, valid and reliable IT governance maturity assessments without the help of an experienced analyst.

    A Bayesian Network for IT Governance Performance Prediction2008Inngår i: Proceedings of the 10th International Con-ference on Electronic Commerce, 2008Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The goal of IT governance is not only to achieve internal efficiency in an IT organization, but also to sup-port IT‟s role as a business enabler. The latter is an ability of an organization here denoted as IT gover-nance performance. IT management cannot control the IT governance performance directly. Instead, their realm of control includes several IT governance maturity indicators such as the existence of different IT activities, documents, metrics and roles. Current IT governance frameworks are suitable for describing IT governance, IT-systems, and business processes, but lack the ability to predict how changes to the IT gover-nance maturity indicators affect the IT governance performance. This paper presents a Bayesian network for IT governance performance prediction. Bayesian networks are widely used for goal modeling and prediction in other research fields. Data from 35 case studies conducted in a variety of organizations has been used to determine the behavior of the network. An assumption on linearity is introduced in order to compensate for the limited amount of data, and the network learns using the proposed Linear Conditional Probability Matrix Generator. The resulting Bayesian network for IT governance performance prediction can be used to support IT governance decision-making.

    Scenario-based evaluation of Enterprise Architecture: A top-down approach for chief information officer decision making2005Inngår i: 7th International Conference on Enterprise Information Systems, ICEIS 2005, Miami, FL, 2005, s. 130-137Konferansepaper (Fagfellevurdert)
    Abstract [en]

    As the primary stakeholder for the Enterprise Architecture, the Chief Information Officer (CIO) is responsible for the evolution of the enterprise IT system. An important part of the CIO role is therefore to make decisions about strategic and complex IT matters. This paper presents a cost effective and scenario-based approach for providing the CIO with an accurate basis for decision making. Scenarios are analyzed and compared against each other by Using a number of problem-specific easily measured system properties identified in literature. In order to test the usefulness of the approach, a case study has been carried out. A CIO needed guidance on how to assign functionality and data within four overlapping systems. The results are quantifiable and can be presented graphically, thus providing a cost-efficient and easily understood basis for decision making. The study shows that the scenario-based approach can make complex Enterprise Architecture decisions understandable for CIOs and other business-orientated stakeholders.
