Designing a process-oriented framework for IT performance management systems

Abstract

In recent years, control and governance of internal services such as Information Technology (IT) have become quite critical in organisations due to the enormous size of their expenditure. As a result, managers have faced growing pressure to measure the performance of IT departments. Several concepts have been developed during the last few years such as IT governance, IT scorecards, and benchmarking that have been considered by IT and business execu-tives. But surprisingly, a recent study by the IT Governance Institute (ITGI) that covered 335 CEOs and CIOs in 21 countries, reported “while more than 91 percent of executives recog-nize that information technology (IT) is vital to the success of their businesses, more than two-thirds of CEOs are not comfortable answering questions about governance and control over their IT processes.” The study validates that the major problem continues to be “the inadequate view of how well IT is performing” (ITGI, 2004). Hence, decision-makers and stakeholders within private and public companies are insisting that IT executives provide hard facts on mission and IT performance. As such, a promising performance management system is required: setting performance targets, designing efficiency and effectiveness measure, systematically and accurately measuring outcomes, and then using the results for fact-based decision-making. This paper shows, which concepts and frameworks currently exist to measure the performance of the IT department and its delivered IS services. We discuss how a performance management system might be designed and implemented with the purpose to monitor and improve the IT function within a major financial institution in Europe. Finally, this paper pro-vides lessons learned and some recommendations for further research in the area of IT performance management.

IT Performance Management - Methodology, Metrics and Application

In: 3rd Conference on Performance Measurement and Management Control (EIASM); Nice/France

Abstract

As many organizations search for ways to compete more effectively in today’s ever-growing markets, managers are increasingly focusing on internal services. One internal service function that has especially gained a lot of attention is Information Technology (IT) due to the enormous size of its expenditure. Increasingly, decision authorities within private and public sector companies are insisting that IS executives provide hard facts on IT mission and performance. Key performance indicators, governance structures, and new reference models (e.g. CobiT) are aimed at demonstrating how well the IT department and relating processes perform and improve over time. In this context, “IT governance” has evolved as a challenge to provide a management control system that aims to annul various frequently found disadvantages of uncoordinated decisions, lack of transparency and insufficient alignment between business and IT goals. Based on a comprehensive analysis of current performance management frameworks, we have designed and deployed an IT management scorecard within a Major European Financial Institution. The paper provides valuable insigths concerning the different implementation steps of IT scorecards and related problems.

Designing a process-oriented framework for IT performance management systems

In: The 12th European Conference on Information Technology Evaluation (ECITE2005); Turku/Finnland

Category: Proceedings

Abstract

This paper show, which concepts and frameworks currently exist to measure the performance of the IT department and it’s delivered, IS services. We discuss how a performance management system might be designed and implemented with the purpose to monitor and improve the IT function. A performance metrics catalogue has been elaborated to document and to enable a common understanding of the individual metrics. Finally, this paper provides lessons learned and some recommendations for further research in the area of IT performance management.

Abstract

Erst die detaillierte Erfassung netzweiter Verkehrsströme hinsichtlich zeitlicher, quantitativer und qualitativer Aspekte kann das Dilemma des IT-Controlling im Rahmen der Erfassung, Bepreisung und Allokation von Netzkosten und -nutzen lösen. Neben den direkt zuordenbaren Netzerlösen bzw. Netzkosten existieren allerdings auch indirekte interdependente Effekte (Netzeffekte), die eine verursa-chergerechte Kosten- und Leistungsverrechnung der IT-Kosten innerhalb von IuK-Infrastrukturen erschweren. In diesem Zusammenhang werden altbewährte und neuartige Auslastungs- und Abrechnungsparameter, sog. Call Detail Records (CDRs) und Internet Protocol Detail Records (IPDRs), als elementare Informationseinheiten von Sprach- und Datennetzen vorgestellt. Ziel dieser Arbeit ist es, einen neuen Beitrag für die Erfassung, Bewertung und Allokation von Netzeffekten in Unternehmensnetzwerken zu liefern. Dabei stehen insbesondere die Quantifizierung sowie das Zuordnungsproblem der Kosten- und Nutzeneffekte in vernetzten Unternehmen im Vordergrund.
